Issue with SUS2MMOrderResponse E1EDPT2 SEGMENT

Hi Experts,

When I try to send a PO Confirmation with multiple items, PO returns an error while mapping PurchaseOrderConfirmation into ORDERS02 IDoc using the SAP standard mapping "SUS2MMOrderResponse"

Error:

Error before sending due to idoc parsing error: (7) IDOC_ERROR_PARSE_FAILURE: Illegal value "2" for attribute SEGMENT in <E1EDPT2 SEGMENT="1"> tag within IDoc-XML for type <ORDERS02>:
state=READING_ATTRIBUTE_VALUE, charPosition=2180, lineNumber=1, columnNumber=2181

Working fine in SAP PI. When migrated to SAP PO started issue.

Found a similar unanswered question before. So raised this new question for your inputs/suggestions to the solution.
