EBP SUS NO PO RESPONSE and Invoice XML MESSAGE CREATED

Hi All,

We have configured EBP - SUS on SRM 7 server with extended classic scenario.PO's are transfering fine from EBP to SUS and are visible in SUS also expected follow on documents are PO response,Confirmation,Invoice.But wen we process the po and confirm all items no po response xml message is created and a local po response is created which is not transferred back to EBP.Later when we create a confirmation for the same po,it is transfered to EBP via serviceack xml message and is visible.

Finally wen v create a invoice it is also created locally and not tranferred to EBP,no xml message is created in this case too.

In XI we are using integration scenario which is based on SRM 5.5 contents.

Any kind of pointers will b appreciated.

Thanks.
