Hi Joseph,
I didn't hear about notification sent from SUS to MM side.
But I know field 'message to purchaser' text sent from SUS to MM:
==========
"In MM-SUS scenario: 'Message to Purchaser' text is not supported by
standard. Reason behind this is the corresponding IDOC is not configured
accordingly from ERP side.This is supported in EBP-SUS scenario only."
==========
However later we provide two notes which are consulting notes to
realize this functionality to address customer's requirements:
761150 - MM-SUS: sending texts from SUS (ORDRSP) to R/3-MM
1342975 - 'Message to Purchaser' field unavailable in MM-SUS scenario
So maybe this would be of help to realize this.
best regards,
Ivy
