In SAP PO, when you install from beginning, IDOCs sent from SAP S4 will not capture in “IDOC Adapter Monitoring”. Short tip below will show you how to solve that issue.
When SAP ERP (ECC, S4) send message to SAP PO via IDOC Adapter, SAP PO will capture IDOC message into “IDOC Adapter Monitor” that useful for you when you want to check inbound idocs from SAP ERP.
By default, this function was disabled. I am not sure why SAP don’t active it by default. With IDOC Integration monitoring this option really important for us when we can check whether SAP PO received IDOC or not.
IDOC messages empty in “IDOC Adapter Monitor”
Make sure you have right to change NWA parameters, refer link
After changed indicator, you can send testing idoc and see results.
