1 Overview This document describes the new features and enhancements in Preactor 12.1, as well as detailing

any defect fixes and considerations for upgrade scenarios.

The primary objective with this release of Preactor is to improve data integration with enhanced

import facilities. However, as detailed throughout this document, there are a number of significant

enhancements that, while beneficial to data integration, also benefit Preactor in other areas, leading

to enhanced performance and improved behaviour in a number of key areas.

It is recommended that you read this document before upgrading to Preactor 12.1. As always, it is

important to plan any deployment and take steps to ensure that you are able to recover from any

unforeseen issues. It is recommended that a backup of the database and configuration is taken prior

to attempting any upgrade. While every effort is made to ensure that upgrading from one version of

Preactor to another is as seamless as possible, it is nevertheless sensible to take such precautions.

1.1 Schema Change Warning

This warning is only applicable when upgrading an existing Preactor configuration from a previous

release. This does not apply to new deployments; the configurations that ship with Preactor 12.1

require no changes to the database schema and are ready for use.

When upgrading from a previous release, Preactor 12.1 requires some changes are made to the

database schema. Preactor will detect that changes are required and prompt you to update your

schema. Changes to the database schema are irreversible and previous versions of Preactor will not

open a database with a later schema version. For this reason you should always take a backup

before upgrading Preactor. The best way to take a backup is to initiate the Preactor Configuration

Manager from with your Preactor configuration by selecting the ‘Generate Support File’ option from

within the ‘Help and Support’ category.

2 New Features and Enhancements This section describes the major new features and enhancements introduced with this release of

Preactor. This is not an exhaustive description, but covers the most significant changes. For a more

complete list, please refer to the Detailed Change Notes.

2.1 Import Improvements

To facilitate improved data integration, the existing import functionality has been enhanced to

support importing from more sources and some limitations on target tables have been removed. In

addition, wizard driven imports for Preactor specific field types such as auto lists and auto dimension

matrix fields have been included in this release.

2.1.1 Import Sources

Previous releases of Preactor provided native support for importing from CSV files. Now, as well as

selecting from CSV files, it is possible to select from a number of other data sources including SQL

Server, Oracle, Access and Excel. Provided the query syntax is understood, data can be queried from

almost any data source and imported directly into Preactor. The procedure for defining import

scripts is unchanged, aside from the steps required to define the data source and the query for the

source data. Existing import scripts will continue to work without modification, though CSV parsing

is now based on a standard parser, so special care should be taken to ensure that any input CSV files

are compliant and any necessary escape sequences are correctly employed.

2.1.2 Wizard Based Matrix Import Scripts

While features do exist in previous releases of Preactor for importing data into auto list fields, those

features are file based, require a fixed header definition and could not be defined using the import

wizard. This approach is not suitable for importing data from alternative data sources.

Though the existing matrix import features continue to function, a new form of import script has

also been introduced in this release to facilitate importing into these field types from whatever data

source you have defined. Auto dimension matrix fields, such as those used for sequence dependent

setup times, are also supported.

For more information on how to define import scripts for matrix fields, please refer to the user

documentation.

2.1.3 Removed Import Table Limitations

In previous releases of Preactor, there were some limitations on the target table of an import script

that have been lifted in this release.

Firstly, in order to be able to import into a table, previous released required that the table was listed

in the ‘PIO Valid Formats’ table. This is no longer necessary, and any user data table can be the

target of an import script. In addition to this, a target table would require an IMPORT MARKER field to

be defined on that table. This is no longer necessary, and IMPORT MARKER fields can be removed

from target tables, provided that there is no subsequent process that relies on the IMPORT MARKER

values.

Finally, though not a limitation that affects only import scripts, the table size limit as defined in the

Preactor table definition (.prtdf) file is no longer a hard limit on the table size. This table size limit no

longer needs to be defined for any table and may be removed. If a table limit is specified, that limit

will be reported through the API method MaximumRecords() for compatibility reasons only.

2.2 Native 64-bit Support

Preactor is now available in both 32-bit (x86) and 64-bit (x64) variants. The 64-bit variant will

execute as a native 64-bit process on a 64-bit operating system. In this scenario, Preactor has access

to far more resources and can solve larger and more complex problems as a result.

For Preactor configurations that have been customised with scheduling rules, PESP custom actions

or sequencer or editor tools, some consideration should be given to this change. If those

customizations depend on components that are 32-bit only, they will not work with the 64-bit

variant of Preactor, and the 32-bit variant should be used instead. This is applicable to all

components that were authored in Visual Basic 6 or earlier. Components authored in a .Net

language are generally agnostic to processor architecture, but their dependencies can still be 32-bit

only. A .Net project that is compiled for a specific architecture (e.g. x86), and not ‘Any CPU’, will also

fail to execute within the 64-bit variant of Preactor.

Another point for consideration is COM registration. It is likely that existing components are

registered as 32-bit components, and therefore 64-bit Preactor will be unable to resolve them.

Components should be re-registered using 64-bit versions of the registration tools. If components

are deployed as part of an installation package, that package will need updating accordingly.

2.3 Performance Improvements

As part of an on-going programme of performance improvements, some significant alterations to

key areas of Preactor have been made for this release. The emphasis is on areas of the software that

affect import performance. The improvements detailed below each play into that theme.

2.3.1 Expressions

Evaluate expressions are a powerful feature in Preactor, allowing for dynamic calculations in table

definitions, event scripts, material control rules and through many other Preactor features. This

release of Preactor sees the evaluate expression engine completely overhauled to provide significant

improvements in evaluate performance as well as some improvements in behaviour.

To facilitate these improvements, expressions are now parsed at the earliest opportunity, and the

resulting expression tree is then re-used, yielding rapid execution along with more deterministic

behaviour. Expressions are now executed on-demand, rather than being updated periodically. This

eliminates delays in initialisation. See the API Methods section for more information on how this

affects the API.

In previous releases of Preactor, one would often need to give much consideration for execution

order and operator precedence, as well as avoiding value injection issues which could result in

altering the meaning of an expression. All of these considerations have been addressed in this

release. For a full explanation of the syntax and behaviour, please refer to the customization

documentation.

It should be noted that expression syntax is more strictly enforced in this release than it was in

previous releases. For this reason, any errors in expression syntax will become apparent when

upgrading, and should be addressed as part of the upgrade procedure.

Columns which are defined with an EVALUATE classification are now represented in the database as

computed columns. This means that those columns may be referenced in reports, but Preactor no

longer has to commit to the database the evaluated value. Should you wish to omit these computed

columns from the database, a new classification is provided for that purpose. For more information,

see the documentation for the classification EXCLUDE FROM DB.

2.3.2 Dynamic Indexing

When resolving record references, Preactor often needs to lookup values on columns defined within

the configuration. Indexing aids these lookups and significantly reduces the time required to

complete the operation. While indexes were applied in some strategic scenarios in previous releases

of Preactor, often relationships would need to be resolved without the aid of an index. In this

release, indexes are dynamically created on any defined column as and when required. This aids

performance in many different areas.

2.3.3 API Methods

EvaluateRecord()

Due to the improvements in the expression engine, the EvaluateRecord() method is now defunct,

and performs no useful action. Calling the method will cause no harm, but code that utilizes this

method should be reviewed, and calls to this method removed at the earliest opportunity.

EvaluateExpression()

EvaluateExpression() works in a different context to evaluate expressions that are defined on

columns, and therefore a different approach to performance is required for this method. Given that

the method takes an expression as an argument, that expression could change every time the

method is called. To achieve the objective of parse once, execute many, this method is backed with

an expression cache which stores the most frequently executed expressions. Performance is

improved because of this approach, but executing expressions using this method will be more

expensive than defining the expression on the table, which would be the preferred approach if

possible.

FindMatchingRecord()

As well as benefiting from improvements in expression performance, which are applicable when

using an expression as an argument to the FindMatchingRecord() method, the method is now

backed by the Dynamic Indexing described above. This will apply an index to columns that are used

with FindMatchingRecord(), drastically reducing the time required to find items.

CreateRecord() & DeleteRecord()

CreateRecord() and DeleteRecord() have been optimised to improve performance. The

improvements are most apparent when working with large data sets.

2.4 GMPS Viewer

Supported as of this release is a new GMPS product called GMPS viewer. Similar to the Preactor APS

Viewer product, this product facilitates the sharing of a GMPS plan between several users without

the need for further GMPS 400 licenses. Unlike the Preactor APS viewer, it is not possible to

manipulate any element of the plan in a GMPS Viewer.

For existing GMPS 400 users it is necessary to update the license, as some features that were not

previously license constrained are now constrained by the license. To request a license update,

please contact support@preactor.com.

offset to be taken from the setup start time and not the process start time.

Resolved an issue where sorting the Demand Colours table in the planner would result in the

colours not updating.

Fixed an issue where the advanced pivot view would not maintain headers when scrolling.

has logged in if the security module is enabled.

Resolved an issue where the ‘Dynamic Bottleneck’ and ‘Min WIP’ APS rules were broken

since they attempted to write to the 'due date' field. It is not possible to do this since it is an

evaluated field and is read only.

Resolved an issue in the Planner where there was a rounding issue with lead times against

the BoM. This happened when the plan was in variable hours.

Resolved an issue where the Bar Text configuration (i.e. the text that is displayed in the bar

on the overview) was not maintained over Sequencer restarts.

Time if the capacity plots are shown by Item in the planner.

Fixed an issue where the calendar resource names would not be properly updated.

Fixed an issue in the planner whereby the item calendars are ignored if the item is planned

weekly mode.

Fixed an index out of range issue whilst dragging demand bars on the stock profile chart.

Fixed an issue where an index out of range exception would be raised whilst using the global

using MADE FROM classification.

Fixed an issue where Preactor would place operations on the planning board later than

necessary when recursively scheduling linked operations where shifts have varying lengths.

Improved performance of Drag and Drop by removing unnecessary recalculation of

secondary constrains.

Fixed an issue where the API couldn't be used during an 'After File Load' event.

3.2 Preactor 12.1 SP1

3.2.1 Features and Enhancements

Added encoding options when importing from file. Options are 'Unicode' or 'Windows

Encoding'. Each option allows several sub-options. ‘Default’, in the case of 'Windows

Encoding', means use the current locale to determine the code page to use. In each case the

encoding or code page can be explicitly set.

Added schema upgrade tasks to add required encoding fields to the Import/Export scripts

table. If upgrading from 12.0 or earlier then the assumed encoding will be Windows

Encoding (Default). If upgrading from an existing release of 12.1 the assumed encoding will

be Unicode (UTF-8).

3.2.2 Defect Fixes

Fixed an issue where the separator specified in an import script would be ignored if Preactor

is not running in English and the separator names have been translated.

Fixed issue where Preactor would fail to import SQL dates where a time element is specified

but the imported value is at midnight.

Improved the capacity smoothing process in GMPS for items with similar days of cover.

Fixed an issue where the Open Planning Board method GetAvailableCapacity() could get

into an infinite loop where a job ends and a calendar shift starts at precisely the same time.

Fixed an issue where resource names in the overview window could be corrupted if the

resource name field has an EVALUATE defined.

Fixed an issue where the example configurations contained incorrect time formatters in

their import scripts.

Fixed an issue using calendar edit mode in Dutch.

Fixed an issue where regional settings could affect the parsing of dates and times when

importing with an explicit formatter defined.

Resolved an issue whereby a DB upgrade failed if there were no import or export scripts

defined.

Fixed an issue where fields that have a name that correlates to a SQL keyword would cause a

schema upgrade step to fail.

Fixed an issue which prevented the renaming of tables using the PREVIOUS TABLE NAME

classification.

Fixed an issue where NULL values would not be evaluated correctly within the corresponding

computed column in the database.

Fixed an issue where evaluating many expressions could cause an ACCESS VIOLATION or

unpredictable results.

Fixed issue where import scripts fail to apply default values where the field name is

translated.

Fixed an issue where EVALUATEs would fail to convert to a computed column when a

comparison to an empty string existed.

Fixed an issue where existing matrix imports might not work if a separator other than a

comma is used.

Fixed an issue where duration fields with custom formats were not imported correctly.

3.3 Preactor 12.1 SP2

3.3.1 Defect Fixes

Fixed issue when sequencing orders which Increment and Decrement secondary constrains

over multiple operations whereby the operations would be placed on the planning board

later than necessary if multiple primary resources could process the operations using

different secondary constraints.

Fixed an issue where the precedence of brackets was ignored in evaluated columns in SQL.

Fixed an issue where Preactor would fail to load data for translatable tables on SQL servers

with a case sensitive collation setting.

Fixed an issue where Preactor would find a record that had been deleted when using the API

method FindMatchingRecord().

Fixed issue where START OFFSET would be ineffective if the quantity field is an evaluated

field.

Fixed an issue where Material Explorer could crash Preactor on opening.

Fixed an issue that could cause a significant reduction in performance when committing data

tables.

4 Known Issues

4.1 Deployment

Upgrades and Side-by-side

Due to changes in technology, Preactor 12.1 has limited compatibility with previous versions of

Preactor 12 and Preactor 11.

If older versions of Preactor are installed after Preactor 12.1 a number of ActiveX related issues will

arise, such as GetTypeInfoCount messages and errors when running certain Preactor modules. To

resolve this uninstall all versions of Preactor and then re-install in chronological order (i.e. 12.0 then

12.1).

The product allows the side by side installation of both the 32 bit and 64 bit version. This is not

supported, and should not be done.

If it is done by mistake - uninstall the version not required, and repair or re-install the version that is.

4.2 Licensing

Network License Activation

If activate is selected, the user is given the choice to activate either local or network license. Only

local licenses can be activated and the network license option should not be offered or used.

Offline License Upgrades

When a user generates a manual upgrade, a request is generated and stored in the licensing storage.

If a new manual upgrade is created, this cancels the existing request and generates a new one. If a

user then tries to apply the result of the first request, it will fail.

This can leave their license in an inconsistent state.

4.3 Import

Import with Country Code

Some demonstration data may not be compatible with all languages. Running a configuration in a

language where Day, Hours and Mins has been translated on DURATION field type, values in

DURATION type fields such as Op. Time Per Item or Batch Time etc. may not be interpreted correctly

when importing data from the import files that ship with the product, resulting in incorrect

operation times and operations that cannot be scheduled. The workaround is to modify the import

file to use the language equivalent for Days, Hours, Mins etc.

4.4 Evaluate Fields

Configuration Changes and Evaluate Fields

The process which makes schema changes to the database in response to changes to the Preactor

Table Definition file can fail when fields with an EVALUATE classification are removed. The process

fails if a field with an EVALUATE classification is removed at the same time as one or more fields

referenced by the EVALUATE statement. The workaround is to remove the field with the EVALUATE

statement, run Preactor so the database is changed, and then remove the remaining fields.

4.5 APS Sequencer

Backward scheduling with constraints

Backward Scheduling an infinite capacity resource with a secondary constraint on setup time only,

does not work as expected. It works like a finite resource.

Highlighting All Bi-Directional Ops

Highlighting ‘all bi-directional ops’ in a configuration with material control will highlight operations

following all material relationships, rather than just the immediate predecessors and successors.

Rounding Issue causing SMC shortages

An issue exists in Preactor where Date/Time values can lose accuracy after a round trip to the

database. This can manifest in a number of ways and typically causes operation sequences that

were valid on commit to become invalid on load. To work around this issue on SQL Server 2008 or

later, the data type for DateTime columns should be changed to DateTime2.

MATCH FIELD and Backward Sequencing

This is an incompatibility between two features. The use of MATCH FIELD only works with forward

sequencing.

Increment for Setup and Backwards Sequencing

This is an incompatibility between the two features. The problem causes the setup time to be

applied twice.

4.6 GMPS Planner

Out of Life Production in Constrained Mode

In a Make to Order GMPS configuration in Constrained Mode, when planning in Hours, Update Out

of Life production needs to be called to refresh the values to state if any production goes out of life.

5 Feature End of Life Notices

5.1 MANIP Module

The MANIP module and all of its functions are deprecated. This module will be removed in an

upcoming version of the software and selected features will be replaced with alternatives.

5.2 Legacy Material Control

The material control module issued prior to version Preactor 11.0 and associated functionality

(includes Static Material Control or SMC, legacy PBX, Dynamic Material Control or DMC) will be

removed in an upcoming version of the software.

We recommend migrating to the latest version of the material control module.

5.3 Legacy GMPS

Legacy GMPS has been replaced by Preactor 400GMPS (introduced in version 12.0). Legacy GMPS

features will be removed in an upcoming version of the software.

We recommend migrating to the Planner module.

5.4 Schedule Analysis

The Schedule Analysis feature has been superseded by the SQL Schedule Analysis Reports. This

feature will be removed in an upcoming version of the software.

5.5 ActiveX tools and rules

The Preactor COM interface has been deprecated and will be replaced by a new API in a future

release.

We recommend all developers to reduce their dependency on the Preactor COM objects

(PreactorObj and OpenPlanningBoard) and instead use the interfaces IPreactor and IPlanningBoard.
