SAP PI/PO Body filter the data in Message Mapping only

[Devin_wei]

Hello experts,

I want to set conditional filtering data on the BODY in Message Mapping to send the data that meets the conditions to a third-party system.But once I've configured it, I'm testing to only map the first piece of data.

I didn't see any difference when I compared it with other interfaces. Is it possible that the other party's interface is causing it?Here's a screenshot of my configuration and testing.

Please support . Thanks.
