Wire ModelThe wire model can be used to create running FPM application by pure

configuration or at least with minimal coding effort. The runtime interdependencies

between UIBBs are defined by configuration entities called “wires” which are based on

reusable “connector” classes implementing the dependency semantics. The primary use

cases for the wire model are object models with generic access interfaces (for example,

ESF, BOPF, or BOL).

A wire controls the runtime interdependencies between two UIBBs; that is, they

determine the data content of the target UIBB depending on user interaction changing the

“outport” of the source UIBB. Outports can be of type lead selection, selection or

collection. For example, the execution of a search on a Search GUIBB will change its

collection outport and may therefore change the data content of a result list displayed in a

separate List GUIBB. Similarly, changing the lead selection in a list of sales orders may

change the data content of another list displaying the associated sales order items.

In order to be part of a wire model, a UIBB needs to implement a certain Web

Dynpro interface which in turn provides a feeder model implementation. The FPM

GUIBBs are automatically integrated if their feeder classes implement the feeder model

interface.

Application areas or object models define their own namespaces for which their

connector classes, feeder model classes can be reused. Moreover, they typically need to

provide a transaction handler class which manages transaction events like save, modify

or check and global message handling.

Wires are defined on the level of the floorplan configuration. For each model

UIBB contained in the floorplan configuration, a source UIBB with specified outport can

be defined. Furthermore, a connector class and, potentially, connector parameters must

be maintained.

If the floorplan contains composite components (tabbed components), the model

UIBBs contained in the tabbed components can also be wired. However, in order to

provide better reusability of composite components, it is also possible to define intrinsic

wiring for tabbed components. A tabbed component can define a model UIBB as a

“wire plug” (this is usually a master UIBB), which serves as an entry point for the wiring

of the tabbed component from the enveloping floorplan component. If a wire plug is

configured for a tabbed UIBB, only the wire plug UIBB can be wired from outside.

Transaction Handler class

The transaction interface provides methods for handling global and transactional

events. In the FPM configuration editor, one transaction handler implementation can be

assigned on the level of the wire model. However, it is not mandatory to specify. But it

can be used for wring some specific logic for Application level events.

Interface “IF_FPM_WIRE_MODEL_TRANSACTION” is implemented for

creating transaction handle class.

Method Method description

START It is called at the starting of FPM

application. It provides 3 things “FPM

Massage manger instance”, “Property

bag of FPM Application”, and

“Runtime information of FPM”. Here,

we can also specify application commit

capability.

AFTER_FLUSH This method is called after FLUSH has

been called for all current UIBBs. It

can be used to flush buffers.

AFTER_PROCESS_EVENT This method is called after

PROCESS_EVENT has been called

for all current UIBBs. It can be used

for handling transactional events for

example SAVE or CHECK.

Moreover, it can be used to collect

messages which here not handled inside

UIBBs and to forward them to the

FPM message handler.

AFTER_PROCESS_BEFORE_OUTPUT This method is called after PBO has

been called for all current UIBBs. It

can be used to collect messages at the

latest possible point in time before

screen output.

AFTER_NEEDS_CONFIRMATION This method is called after

NEEDS_CONFIRMATION has been

called for all UIBBs. It can be used to

analyze and add confirmation requests.

IS_DIRTY This method can be used to indicate a

dirty state for the work protection

mode.

Connector Class



The “IF_FPM_CONNECTOR” connector interface comprises an interface,

“IF_FPM_CONNECTOR_DEF”, defining the access by the FPM framework and an

interface “IF_FPM_CONNECTOR_RUN” for runtime access by the application feeder

model.

The definition interface possesses a static attribute, “SV_NAMESPACE”,

which should be filled with the namespace (ex. ‘FPM_DEMO’ or ‘BOL’ or user

specific) in the class constructor of a connector implementation (for example in a

common superclass).

Method for “IF_FPM_CONNECTOR_DEF”


GET_PARAMETER_LIST Connector classes can be parameterized to

flexibly control their runtime behavior. The

parameter values are maintained for the wires

in the FPM configuration editor. A parameter

is defined by a name, its data type and a

descriptive text.

INITIALIZE With this method the connector is initialized

with the parameter values. This method is

called by the FPM runtime upon UIBB

instantiation.

GET_PARAMETER_VALUE_SET With this method, a connector implementation

can provide a value set for each parameter.

For example, in an object model a parameter

may carry the association name. For a wire

between specified UIBBs, the method may

provide a list of all associations between the

source and target business object node.

SET_INPUT Receives an object reference carrying the

actual data of the connected outport. This

method is called before the UIBB‟s PBO by

the FPM runtime.

Method for “IF_FPM_CONNECTOR_RUN”


GET_OUTPUT Returns an object reference carrying the actual data to

be displayed by a UIBB. This method can be called by

the UIBB at PBO for example in the GET_DATA

method of a feeder class.

IS_CREATE_ALLOWED Returns a Boolean indicator whether entity creation is

allowed. This method can be called by the UIBB at

PBO to dynamically control the activation of create

buttons for example to maintain the action usage

parameter in the GET_DATA method of a feeder

class.

CREATE_ENTITY Creates and returns a data entity which can be

arbitrarily typed. This method can be called by an

action handler of the UIBB for example in the

PROCESS_EVENT method of a feeder class.

There are total seven methods in connector interface “IF_FPM_CONNECTOR” that

should be implemented in connector class. We should also create class constructor for

setting “Namespace”. “SET_OUTPUT” and “GET_OUTPUT” is bridge between FPM

components, so these methods should be implemented properly.



Wire for Free UIBBs

Wire model is implemented on Web Dynpro component by implementing

“IF_FPM_UIBB_MODEL” Web Dynpro interface. It contains only one method

“GET_MODEL_API” which is used to set “FPM Feeder Model” for Free GUIBBs. It

contains only one parameter “RO_FEEDER_MODEL”. So, we have to create a FPM

Feeder Model class and assign to that parameter.

FPM Feeder Model Class – Interface “IF_FPM_FEEDER_MODEL” is

implemented for creating Feeder Model Class.

Method for “IF_FPM_ FEEDER_MODEL”


GET_NAMESPACE Returns the namespace of the underlying application

area. Method is called at design time.

SET_CONNECTOR Called upon instantiation of a UIBB. It hands over the

connector (reference to

IF_FPM_CONNECTOR_RUN) which can be

accessed for data retrieval at PBO.

GET_INPORT_KEY Returns a reference to an object key which characterizes

the meta data type expected at the import (for example

the business object node). Method is called at design

time.

GET_OUTPORTS Provides a table of outports comprising the object key,

the port type an identifier and a descriptive text. Method

is called at design time.

GET_OUTPORT_DATA Returns an object reference carrying the actual data

identifier for a certain port. Method is called at runtime.

Assistance class can also be used as Feeder Model Class and reference

“WD_ASSIT” can used as Feeder model instance.

Ex: METHOD get_model_api . ro_feeder_model = wd_assist.

ENDMETHOD.

Wire for GUIBBs

Nothing special we need to do that. Interface “IF_FPM_FEEDER_MODEL” is also

implemented on feeder class for getting port support. We need to set port

manually using structure “IF_FPM_FEEDER_MODEL=>CS_PORT_TYPE”.

It contains three constants “COLLECTION”, “SELECTION” and

“LEAD_SELECTION”. It should be properly configured.

Re: Create Wire Model in webdynpro FPM.

Wire ModelThe wire model can be used to create running FPM application by pure

configuration or at least with minimal coding effort. The runtime interdependencies between

UIBBs are defined by configuration entities called “wires” which are based on reusable

“connector” classes implementing the dependency semantics. The primary use cases for the

wire model are object models with generic access interfaces (for example, ESF, BOPF, or

BOL).

A wire controls the runtime interdependencies between two UIBBs; that is, they

determine the data content of the target UIBB depending on user interaction changing the

“outport” of the source UIBB. Outports can be of type lead selection, selection or

collection. For example, the execution of a search on a Search GUIBB will change its

collection outport and may therefore change the data content of a result list displayed in a

separate List GUIBB. Similarly, changing the lead selection in a list of sales orders may

change the data content of another list displaying the associated sales order items.

In order to be part of a wire model, a UIBB needs to implement a certain Web

Dynpro interface which in turn provides a feeder model implementation. The FPM

GUIBBs are automatically integrated if their feeder classes implement the feeder model

interface.

Correct Answer

Manishekhar Singh Nov 26, 2012 7:48 AM (in response to Pappu Mehta)

http://scn.sap.com/message/13679972#13679972





Application areas or object models define their own namespaces for which their connector

classes, feeder model classes can be reused. Moreover, they typically need to provide a

transaction handler class which manages transaction events like save, modify or check and

global message handling.

Wires are defined on the level of the floorplan configuration. For each model UIBB

contained in the floorplan configuration, a source UIBB with specified outport can be

defined. Furthermore, a connector class and, potentially, connector parameters must be

maintained.

If the floorplan contains composite components (tabbed components), the model

UIBBs contained in the tabbed components can also be wired. However, in order to

provide better reusability of composite components, it is also possible to define intrinsic

wiring for tabbed components. A tabbed component can define a model UIBB as a “wire

plug” (this is usually a master UIBB), which serves as an entry point for the wiring of the

tabbed component from the enveloping floorplan component. If a wire plug is configured

for a tabbed UIBB, only the wire plug UIBB can be wired from outside.

Transaction Handler class

The transaction interface provides methods for handling global and transactional events.

In the FPM configuration editor, one transaction handler implementation can be assigned

on the level of the wire model. However, it is not mandatory to specify. But it can be used

for wring some specific logic for Application level events.

Interface “IF_FPM_WIRE_MODEL_TRANSACTION” is implemented for

creating transaction handle class.


START It is called at the starting of FPM

application. It provides 3 things “FPM

Massage manger instance”, “Property

bag of FPM Application”, and “Runtime

information of FPM”. Here, we can also

specify application commit capability.

AFTER_FLUSH This method is called after FLUSH has

been called for all current UIBBs. It can

be used to flush buffers.

AFTER_PROCESS_EVENT This method is called after

PROCESS_EVENT has been called for

all current UIBBs. It can be used for

handling transactional events for example

SAVE or CHECK. Moreover, it can be

used to collect messages which here not

handled inside UIBBs and to forward

them to the FPM message handler.

AFTER_PROCESS_BEFORE_OUTPUT This method is called after PBO has been

called for all current UIBBs. It can be

used to collect messages at the latest

possible point in time before screen

output.

AFTER_NEEDS_CONFIRMATION This method is called after

NEEDS_CONFIRMATION has been

called for all UIBBs. It can be used to

analyze and add confirmation requests.

IS_DIRTY This method can be used to indicate a

dirty state for the work protection mode.

Connector Class



The “IF_FPM_CONNECTOR” connector interface comprises an interface,

“IF_FPM_CONNECTOR_DEF”, defining the access by the FPM framework and an

interface “IF_FPM_CONNECTOR_RUN” for runtime access by the application feeder

model.

The definition interface possesses a static attribute, “SV_NAMESPACE”, which

should be filled with the namespace (ex. ‘FPM_DEMO’ or ‘BOL’ or user specific) in the

class constructor of a connector implementation (for example in a common superclass).

Method for “IF_FPM_CONNECTOR_DEF”


GET_PARAMETER_LIST Connector classes can be parameterized to

flexibly control their runtime behavior. The

parameter values are maintained for the wires in

the FPM configuration editor. A parameter is

defined by a name, its data type and a

descriptive text.

INITIALIZE With this method the connector is initialized with

the parameter values. This method is called by

the FPM runtime upon UIBB instantiation.

GET_PARAMETER_VALUE_SET With this method, a connector implementation

can provide a value set for each parameter. For

example, in an object model a parameter may

carry the association name. For a wire between

specified UIBBs, the method may provide a list

of all associations between the source and target

business object node.

SET_INPUT Receives an object reference carrying the actual

data of the connected outport. This method is

called before the UIBB‟s PBO by the FPM

runtime.

Method for “IF_FPM_CONNECTOR_RUN”


GET_OUTPUT Returns an object reference carrying the actual data to be

displayed by a UIBB. This method can be called by the

UIBB at PBO for example in the GET_DATA method of

a feeder class.

IS_CREATE_ALLOWED Returns a Boolean indicator whether entity creation is

allowed. This method can be called by the UIBB at PBO

to dynamically control the activation of create buttons for

example to maintain the action usage parameter in the

GET_DATA method of a feeder class.

CREATE_ENTITY Creates and returns a data entity which can be arbitrarily

typed. This method can be called by an action handler of

the UIBB for example in the PROCESS_EVENT

method of a feeder class.

There are total seven methods in connector interface “IF_FPM_CONNECTOR” that

should be implemented in connector class. We should also create class constructor for

setting “Namespace”. “SET_OUTPUT” and “GET_OUTPUT” is bridge between FPM

components, so these methods should be implemented properly.

Wire for Free UIBBs










Method for “IF_FPM_ FEEDER_MODEL”


GET_NAMESPACE Returns the namespace of the underlying application area.

Method is called at design time.

SET_CONNECTOR Called upon instantiation of a UIBB. It hands over the

connector (reference to IF_FPM_CONNECTOR_RUN)

which can be accessed for data retrieval at PBO.

GET_INPORT_KEY Returns a reference to an object key which characterizes

the meta data type expected at the import (for example the

business object node). Method is called at design time.

GET_OUTPORTS Provides a table of outports comprising the object key, the

port type an identifier and a descriptive text. Method is

called at design time.

GET_OUTPORT_DATA Returns an object reference carrying the actual data

identifier for a certain port. Method is called at runtime.



Ex: METHOD get_model_api . ro_feeder_model = wd_assist.

ENDMETHOD.

Wire for GUIBBs

Nothing special we need to do that. Interface “IF_FPM_FEEDER_MODEL” is also

implemented on feeder class for getting port support. We need to set port manually

using structure “IF_FPM_FEEDER_MODEL=>CS_PORT_TYPE”. It contains

three constants “COLLECTION”, “SELECTION” and “LEAD_SELECTION”.

It should be properly configured.

Dear all,

Wiring between components can be done mainly by two type of FPM class.

Transaction Handler class: It is implemented globally for a FPM Application.

However, it is not mandatory to specify. So, you can make an application without using

any transaction handler.

Use interface IF_FPM_WIRE_MODEL_TRANSACTION

Connector Class: It is main and mandatory part for implementing wire model. Here

you can specify the Namespace and this namespace plays big role for passing data.

Namespace: The definition interface possesses a static attribute,

“SV_NAMESPACE”, which should be filled with the namespace (ex. ‘FPM_DEMO’

or ‘BOL’ or user specific such as XYZ_NS) in the class constructor of a connector

implementation.

Wire for Free UIBBs










Ex: METHOD get_model_api .


ENDMETHOD. Wire for GUIBBs: Nothing special we need to do that. Interface

“IF_FPM_FEEDER_MODEL” is also implemented on feeder class for getting port

support. We need to set port manually using structure

“IF_FPM_FEEDER_MODEL=>CS_PORT_TYPE”. It contains three constants

“COLLECTION”, “SELECTION” and “LEAD_SELECTION”. It should be properly

configured.

In addition of this, create collection handler class that will be passed between

components for retrieving and fetching data.

Hi Manishekhar Singh ,

While I appreciate the info you provided in a few discussions, I've found it a bit complicated

to follow and understand. Why don't you write a nice Blog or How To Document on this

subject?

Cheers,

Custodio
