This is a vendor Management Inventory scenario (VMI).We have XI setup between SAP and 3rd party system.
We have a requirement where we are receiving ORDRSP IDOC (Inbound) message from 3rd party system via XI into SAP whenever stock falls below threshold level it creates PO in SAP MM .
Now we want to send technical acknowledgement for the same whenever successful idoc ORDRSP is posted . There are no contents of this acknowledgement message just it means IDOC is "Received".
How can we do this.
