ALE IDOC Tutorial for ABAPers

The purpose of ALE IDOC is to help the ABAP Developers to get an idea on how to setup all the necessary configs needed to send and receive idocs. This is the MUST guide for you if you are wondering where to start with the ALE IDOC Development and this pretty much covers around all the required business cases. All the below steps are explained in detail.

1. Understanding and Configuring client to client setup: Walks you through defining logical system, assign logical system to the client, create RFC Destination and preparing distribution model, generating partner profile, view partner profile created in the sender system, view port information in sender, how to distribute customer distribution model and generate partner profile in the receiving client and a sample example of configuring and distributing material master across other systems.

2. System to system ALE setup: Create Logical Systems for both sender and Receiver, Assign Logical Systems to Clients, Create RFC Destination, Maintain Customer Distribution Model, Generate Partner Profile, Distribute Customer Distribution Model, Generating Partner Profile in the Receiving Logical Systems, Create /Change Material master records, Distributing Records in the Receiving logical system, Checking IDoc status in the receiver system and Check Material in Receiver System. 3. Two way server to server communication:  Practical examples to customizing for Sending Vendor master from one client to another, additional customizing required to send material master from one system to another and customizing for receiving idocs from another system.

4. Covers other important topics on IDOCS: T-RFC Reporting, Setting up Audit Reporting, Manually Process IDoc in Receiving System, Collect IDoc and Transfer,Creating Filter Objects, Segment Filtering
Creating Reduced message type, Change Pointers Technique, Reprocessing IDocs not posted due to errors & Processing Idiocy waiting in the queue.

5. Developing and Transmitting new IDoc:  Prepare data container in both sender and receiver, Prepare Segments(WE31), Prepare IDocs with the segments in both systems (WE30), Create new message type in both the systems (WE81), Link new message type with IDoc type in both systems (WE82), Maintain two logical systems, one for sender- another for receiver in both the systems (BD54) , Assign Logical System for Receiver to appropriate client in Receiver system and assign logical system for sender to appropriate client in sender system (SCC4) and Create RFC Destination for Receiver in sender system and for sender in receiver system(SM59), Create Customer Distribution Model for the Message type in sender systems(BD64), Generate the partner profile in the sender system(BD82), Distribute the CDM from sender system to the reciver system(BD64), Create the outbound program in sender system to populate and distribute the Idocs(SE38) , Develop Inbound Function Module in the Receiver System(SE37), Create new Idoc Object in Business Object Repository(SWO1) in Receiver system, Create a new task based on Application Idoc object(PFTC) in Receiver system, Allocate Function Module to the Message type(WE57) in Receiver system, Define settings for Inbound FM in Receiver system(BD51), Create New Process code for the Inbound process(WE42) in Receiver system, Assign Input Methods(BD67) in Receiver System & Generate Partner Profile in Receiver System(BD82).

6. Standard IDOC Extension: Building Append structure, adjusting exits to populate data in the extended idoc structure, linkage with the message type and the basic idoc type in sender system, adjusting partner profiles, testing, writing code in the receiving system and checking if the data has been received corrrectly.

7. Creating change documents for the new information & Configuring and developing for change pointers for a custom message type.

8. Downloading IDoc into Application Server: Creating the file port, changing outbound partner profiles, trigger the outbound process.
