Dear Forum,
I have got the help about this subject and quite clear. Thanks for all have helped.
Now I need to confirm 1 more part.
Assuming in PO there are 2 scenarios where gr based iv is ticked and also not ticked, after both GR and miro done (complete the process from PO until book vendor invoice in miro), I purposely do another miro invoice type referring to these 2 PO.
I just wonder why the item line still enabled with quantity and amount fields empty? I thought the line item should be totally grey out?
Need advice.
Thanks
Rgds
