How to handle LE movement type 122 in SAP WM

HI All,

  How to handle return to vendor (IM mvmt 122) in SAP WM.

Senario is:

Step 1: Performed GR (101)  for PO in MIGO

           - System created TR(WM mvmt 101) and stock moved to interim storage location (902)

           - I have not created TO from TR purpusfully

Step 2:I found some thing wrong and want to return to vendor

      - Return to vendor (122) in MIGO

      - System created another TR (WM mvmt 102) to issue from interim storage location (902)

       - I tried to process TR and unable to complete as its ca't find source bin

Please advise.

Actually, If I move stock from interim storage to WM bins and process Return to vendor is successful.

Thanks
