What is GP Web Services?

Do you understand the GP Data Model?

Tables|Fields|Relations?WS is a way to talk to GP with out having to understand the BackEnd.Lets Hide\Encapsulate all the complex stuff and talk to something descriptive

(human readable!!)

GP Web Services

Workflow

Business Portal

BDC / Search

GP Web Services-Installs to IIS server, and to SQL server. -Consoles can be installed on any machine that can talk to IIS.-Dependency is on

- eConnect: It needs access to API through COM+, and stored procedures.

- IIS- ADAM/Azman for security

Workflow-Installs to MOSS/IIS Server -Dependency on GP Web Services and Windows Workflow

Role BasedWhat Operations belong to that Role?What Tasks Belong to those operations?(e.g., Sales Person)What do can you see?

Security Subsystem

Customized Data Based on Roles

You are a SalesPerson and you are assigned to a set of customersGetList (basedonCustomerId) returns only the customers you are assigned

Dynamics GP Policies

What is a Policy?Internal Policies

e.g., Force Credit Limit(s)External Policies

e.g., Create a customer with a default Class ID

Role BasedEach role can have a different set of policies.

Exception SubSystem

There is an error…Is it safe to send back the details?!

Not necessarily!We return a “error”, but to see all of the data, information behind the issue, you can retrieve it from the Exception ServiceExpose Exception Method

Data Access Layer

We talk to the Back Office For you…Business Logic/ Validation is done against the data, and performed automaticallyThis is the “magic” layer for you…

Using GP Web Services…

1) Create a Proxy, or use the shipped one

2) Generate a Context3) Decide, from the Proxy, What Web

Operation you are calling4) Build up your operation call using

strongly typed objects in the interface

Proxy-Up The Service…

DynamicsGP clientProxy = new DynamicsGP()That’s IT!Is this slow for you?

Why is it slow sometimes?!!!!![Best Practice]

What happens underneath?Do you really want to know?

Thinning the contract…

ASMX Can Be Customized!

How?!Create a new ASMX, point it to our assemblyThat’s it!Want a demo?

The Service Contract exposes various CRUD operations that include additional GP Specific operations

Get_ : Retrieves individual DocumentsGetList_ : Returns a Collection of objectsCreate_ : Creates new documentUpdate_ : Updates an existing documentDelete_ : Deletes an existing documentVoid_ : Voids an existing transactions

300+ Web Operations
