Hi Michael,
Thanks for your suggestion.
I found that item stage data for Ship to / ship from location along with country code are missing while transferring from SAP TM to SAP ERP.
I have been using the same master data in my previous testing were it was working perfectly.
Suddenly when i have tried to generate billing document in SAP ERP for same FWO, the error persists.
Please let me know is there any configuration available in SAP TM to generate the billing document as item stage wise.
Thanks
Satish
