PO update should block outbound idoc with Ref inbound IDOC for interface
I want to block PO chages aknowledgement though interface to other legacy system .
Probelm : When ever new PO created We send some of the perticular details to other legacy system throgh interface (EDI) outbound IDOC , Also we receive some changes from legacy system to SAP through inbound IDOC and it update in SAP . Now the probelm is changes in PO again trigering outbound IDOC to legacy system as exception message or aknowledgement , we want to stop this outbound IDOC creation when ever PO update happens in SAP through legacy system interface .
So how we can stop change update for perticular partner function . We want to send outbound IDOC for newly created PO and changes we do SAP system we don't want outbound idoc for auto updation of PO through interface (inbound idoc).
Is it any notes avilable for above problem or is it possible hard code any SAP standard program or any conditions we can use for this problem
