Calling a BAPI Asynchronously from an SAP System
This example demonstrates how to call a BAPI asynchronously from an SAP system over the Web. For this purpose, you have to create an ABAP program inside the SAP system. This program calls the proxy function module to generate an ALE message for a BAPI. After performing a COMMIT WORKcommand, the SAP system will generate an IDoc through the ALE service layer and send it to Adapter for SAP. There the IDoc will be transformed into the original BAPI representation and sent as XML using HTTP to any remote web system.
Note:
While BAPI function module names usually start with the prefix BAPI_, the corresponding ALE proxies are usually named equally with the prefix ALE_
To run an example, you should set up your SAP system for ALE processing as described in the SAP system documentation and in this guide. When defining the partner profile for the outgoing IDoc in the SAP system, ensure that the option Transfer IDoc immediatelyis selected because the BAPI conversion tool on Adapter for SAP does not support IDoc packages.
Create the following report in your SAP system to test the BAPI conversion with the BAPI Bank.Create(available as of SAP release 4.6C).
