Mukthar,
Thanks for your feedback.
In your reply,
"With a debit balance, the transaction is seen as "invoiced, but not delivered"."
So, in my example case, since inventory is canceled(returned), debit balance is remained.
(Dr.GRIR, Cr.Inv)
But, in this case, obviously, Not invoiced yet.
And, by F.19, it seems like SAP recognized as
negative value of "delivered, but not invoiced".
Since this is inventory cancel, SAP's action seems correct.
So, my question is "How SAP recognize it as "delivered, but not invoiced",
even though GR/IR balance is in debit side".
