Hi Experts,
We are getting below error log in NWA while trying to send an IDOC (we19) from S4 system to PO(7.5) system.
We tried all the possible ways but no success.

This Logical system we have not created, this automatically popups when we trigger the IDOC. This comes automatically under sender port i.e S4HANA.

Could you please help here, we are trying to send an IDOC from S4 to PO from the past 2 days but no success.
PFB Screenshot for reference.
