SAP PI 7.3 AEX Multi mapping: Mapping failed with exception


I am encountering an issue with the multi mapping in SAP PI 7.3 AEX system.

Requirement for my interface is to pull a single file which has multiple records from the file directory.

Interface need to split the single file to multiple files.

For this I have implemented multi mapping in SAP PI 7.3(Stand alone Java) to split the single file to multiple files just like the way it is done in SAP PI 7.1. Tried this interface in SAP PI 7.1 system and works fine end to end.

I have done the testing in mapping(Test tab) in operational mapping, I could see response is getting generated successfully.

But when testing end to end,

I could see message is getting failed during mapping with the exception "failed to execute: ArrayIndexOutOfBoundsException: 1” .


Occurrence has been changed to 0..unbounded in the Signature tab of the message mapping & same interface works fine in SAP PI 7.1

Our system is currently on SAP PI 7.31 (AEX) SP05 Patch "0".

Kindly let me know if someone has any idea on this particular exception in SAP PI 7.31 multi mapping Interface.

Thanks & Regards

    Hi Rama,

    In PI 7.3.1, the multi mapping is different. In source side, the occurrence should be 1 and in the target side the occurrence should be 0..unbounded.

    It will work

    Kind regards,
