Dear Umesh ,
Thanks for sharing the excellent document ,
Now its clear the difference between by Product & Co-product from Configuration / Master data setup .
So in my case it is DIMP scenario
For co-product -- it is working fine and Auto GR is also working fine in Confirmations screen with mvt type 101 ..
For By-Product -- I have only maintained neg sign in BOM & in material master MRP-2 ; i have kept it blank --.
Still i m not getting the mvt type 531 in Auto GR nor in MIGO .
My Scenario is for DIMP (Discrete Industry Mill Product ) -- Fabrication Industry --- > if any comments
