BPM generates duplicate messages (sometimes)

47 Views

Hi experts,

I have a strange problem.

Scenario:

- BPM Component sends message to interface A and interface B in PI, in parallell.

- Interface A is synchronous, interface B is asynchronous.

- If interface A answers with a normal response message, everything is fine (no duplicates are created).

- If interface A answers with a fault message type, two messages are generated for interface B. However, the BPM process itself says it only creates one message.

- Interface B is used in Integration Flow which via IDOC adapter sends two IDOC types to ECC (multimapping).

Why are duplicate messages sent to interface B, when interface A responds with fault message type? And why does BPM say it only created one?

BPM model attached below.

Thanks
