Today, I encountered strange error while posting goods receipt against STO (at receiving plant) in MIGO. User was posting GR with reference to Outbound delivery (of sending plant).
MSSA-SATRA exceeded by 23.300 TO
Was stuck and found no help online.
Then upon searching in MB51, I found that user posted a document with two line items of same delivery!
Cancelled the document, and posted without error!
You learn everyday!
