AIS – Advanced Integration Service
Topics
• Overview of WebSphere Adapter for SAP
– WebSphere Adapter supports all SAP Interface Types
• Developing SAP Integration as SCA Service in 3 Steps
• Development Walk thru (Step-by-Step) using IBM Integration Designer (IID)
– Step 1: Generate SAP Interface (e.g., BAPI) as SCA Service Component
– Step 2 a: Create Business Object Data Mapping in IID
– Step 2 b: Create Mediation flow to transform Complex SAP BO to simplifed BO and vice-versa
– Step 2 c: Create BPEL Microflow for Invoking SAP Interface and for any related business logic
– Step 3: Unit Test developed SAP Service Interface
• IBM BPM v8.5.x includes AIS Pattern for SAP that simplifies “Step 2a-c” by generating interface artifacts, incorporating ‘good integration practices’
– the developer needs to ‘fill-in’ specific parameter values, thus saving significant time for rapid development. Helps address developer skills gap
– helps minimize developer learning curve and ensures consistency

WebSphere Adapter for SAP (v7.5.0.3)
• Iterative EIS metadata discovery with zero coding efforts • SAP Adapter Wizard discovers SAP metadata iteratively with no coding
• Supports SCA programming model (Import/Export/Interface)
• Bi-direction integration support • Supports both inbound and outbound interaction with EIS.
• Security • Connection properties either through Managed Connection Factory properties
• Java Authentication and Authorization Services (JAAS) alias

WebSphere Adapter enables Rapid SAP Integration in “3 Steps” Simplifies integration and eliminates custom coding. Improves reusability
Step 1 – Generate SAP Interface as SCA Service – Generate Service Component for the identified SAP function
(BAPI, RFC, IDoc, Table, etc). No SAP skills needed • This is done using External Service Wizard in IBM Integration
Designer (IID) and using WebSphere Adapter for SAP.
Step 2 – Complete Data Mapping & Service Invocation – Develop Data mapping using graphical tool to handle data
transformation.
– Create BPEL flow for ‘Service invocation’ and business logic
– Exposed as Advance Integration Service (AIS) for invocation by a Service Activity in a Process Application (BPD)
Step 3 – Unit Test the Service in IBM Integration Designer – Validate Service functions as designed using Unit test facility
in IID by connecting to SAP system (Dev / Test).
The generated Service (Adv Integration Service) is ready for use in any Process Applications (BPDs).
– Reuse the Service for different interaction styles • such as Web service, JMS call or plain old Java call by wiring with
any other Service Component (SCA)

Step 1: Generate SAP Interface as SCA Service Component
1. Generate Service Component for the identified SAP function (BAPI, RFC, IDoc, Table, etc). No SAP skills is needed, only name of BAPI, Function Module or IDoc
• An External Service Wizard for SAP Adapter in IBM Integration Designer (IID) guides the developer through steps needed to
• ‘discover’, generate’ SAP function as a ‘Service Component’ based on SCA standard.
Tool: IBM Integration Designer External Service Wizard External Service
Wizard to ‘discover’, ‘generate’ Service Interface for BAPI,
IDoc

Step 1: Generate SAP Interface a …. continued
2. Integration Artifacts generated by IID External Service Wizard for SAP
– Interface to invoke BAPI, ALE or RFC
• An Export for SAP Inbound call
• An Import for SAP Outbound call
– Business Objects for BAPI, IDoc, SAP Table
Tool: IBM Integration Designer External Service Wizard
Generated ‘Service Interface’ for BAPI
(PO GetDetail)
Generated ’Business Objects’ representing
SAP BAPI (PO GetDetail)
Complex SAP BAPI Business Object (Parent & Child Objects) The calling application must populate data for all fields in the required format to post a transaction in SAP
SAP PO BAPI Method
SAP PO BAPI Parent Object
SAP PO BAPI Child Object Data Structure
Step 2 a: Create Data Mapping in IID
Tool: IBM Integration Designer – Business Object Map Editor
Complex SAP BAPI Data Structure – needs to be mapped from source BO data
Simple Business Object used in BPMN human workflows
Custom Data mapping
Step 2b: Create Mediation flow
Service Activity in BPD invokes SAP AIS
• SAP Bos (BAPI, Idoc) are complex • Use of mediations for converting BAPI BOs
to easily consumable BOs intended for business users
Tool: IBM Integration Designer – Mediation Flow Editor
Step 2 c: Create BPEL Microflow for Invoking SAP Interface and for any related business logic
Tool: IBM Integration Designer – BPEL Process Editor
Step 3: Unit Test SAP Service Interface
Tool: IBM Integration Designer – ITC (Integration Test Client)
