File to Multiple Proxies - Tips & Tricks

Posted on Aug. 16, 2010 at 10.10 PM - Kuala Lumpur, Malaysia

Proxy is one of the most useful option when it comes to integrate SAP back end with SAP PI. However if we have to process million of records in one proxy call, then chances of having it ended up with error are high. So, it's also quite common for us to either chop the file into smaller chunk or create multiple proxy calls. The latter scenario will be discussed in this blog.

Tips:

1. We need to change the multiplicity of the target message from 1 to 0...Unbounded in both message and operation mapping
   • Over here, UDF is required to split the records into multiple Proxy. Please refer to my previous blog Controlling Multiplicity of IDOC using UDF.
2. Create SOAP receiver to point to local integration engine of your target system if you are not using SAP PI 7.1, or you can use Proxy receiver for SAP PI 7.11 and above.
3. Make sure interface determination is populated with the correct operation mapping and its multiplicity
   • Be careful, if you have created the configuration objects using process integration scenario model, as the generated interface determination, may not be correctly created. If it's not properly created, delete it and recreate it again.
4. During the configuration test, we should be able to see there are multiple generated messages once it passes interface determination step.
