Multi mapping error, Split mapping created no messages

pi_consultant1 — Mon, 20 Nov 2023 09:13:23 GMT

Hello Experts,

I get the following error when there is no message created in a multi mapping:

Transmitting the message to endpoint <local> using connection HTTP_AAE_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.RetryControlException: Split mapping created no messages, cannot proceed. Review your mapping setup: splitting to 0 messages is not allowed.

Ive already removed the empty tags and namespace so only XML declaration in first line is passing through, but I still get an error.

Can you please advise what I need to do and how to do it, so that I dont get this error.

Thank you in advance,

John

Hi! Do you have 0..unbounded occurence in operation mappings target message chosen?

Hi, yes, all set to 0..unbounded.

Any advice/suggestion what to do and where to look next?

If you exactly know when the message will not be created then you can add filtering on receiver determination step in iFlow/iCo and avoid running the flow for empty messages.
