Purchase order change inbound idoc ?

There are lot of threads on Purchase Order change idoc but there's no one explaining the scenrio below.

Scenerio: Client has legacy sytem(E) and S/4 HANA system(S). Now the requirement is to send change PO from E -> S. So from Source system(E) we are able to trigger ORDCHG message type but same message type does not work in target system(S) because it tries to change Sales Order.

Similarly, we tried to explore PORDCHG but this message type is only for inbound and not for outbound.

So do we have any message type which we can use in both source and target systems for PO Change. Otherwise we have to build Z message type(that would have lot of efforts.).

Please suggest.

Could you clarify ?

You are trying to udpate a Purchase Order using ORDCHG ? But ORDCHG is for Sales order, no ?

In system E and S you have a Purchase Order ?

You have to perform some ALE customizing (partner profiles and the like)

Read a blog such as Integrating MM & SD Modules in Same Client to Create Sales order in Supplying Company Code Using PO ... and Part2

And adapt it to your case.

ORDCHG in target syste is for updating sales order and not purchase order but we only want to update Purchase order in target system.

Is the sales order in the legacy system ?

Is the purchase order in the S4 system ?

If yes then it means you change the sales order in the legacy and you want this change to be reflected in the purchase order in S4 ?

==> outbound Idoc from legacy (sales order change) ==> inbound Idoc S4 (purchase order change)
