We are having a peculiar issue of 'Error while reading the PO in the Backend system. Inform system admin'.
The P.O is in ordered status in SRM but the same is not getting transferred to backend ECC system.
No error messages or logs in RZ20, SLG1 any where.
All programmes like BBP_GET_STATUS_2 and CLEAN_REQREQ_UP are running fine.
Tried pushing the P.Os manually using function module (BBP_PD_PO_TRANSFER_EXEC_V2) to backend ECC.
It was working fine till a week ago and suddenly this problem is coming.
We had implemented few OSS notes suggested by SAP for the issue of 'shopping carts appearing in sourcing cockpit even after P.O creation' in both development and test system.
Now this issue is coming up in test system where as development system is working fine.
Please let us know where to look and how to resolve this issue.
A quick response would be highly appreciated.
