Posting confirmation via ORDRSP needs to generate PO output ORDCHG
We have a requirement where we would like to trigger change output on purchase order when PO confirmation posts via ORDRSP, when we add confirmation manually system triggers the output successfully but when we post idoc ORDRSP system doesn't recognize the change and doesn't trigger the output, however I see change on the PO.
How can we achieve this requirement? is there any standard config? or do we need to put any custom logic?
