Hi Gurus,

Pls help me to find what may be wrong with below Invoice Posting.

a) PO created for Return

b) GR with 161 MOVEMENT

c) MRRL run for this GR

d) Reversed the 161( 162 posted)

e) Now to cancell the Invoice I am trying to run MRRL with referance to reversed GR.

But the system says NO DOCUMENTS SELECTED.

Please help to resolve the issue..

Thanks..
