I have case in a Purchasing
Where GR and Invoice and posted for partial quantity and reversed for some reason by business
PO history shows multiple GR reversal and Invoice reversal..
But i see GR posted for one amount and reversal posted for different amount then received amount (Material has Moving average price valuations)
This situation might happen due to various reason where GR could have reversed after invoice posted with different price or the material could have been consumed which is updated moving average price and then GR is reversed..
Due to this when i see PO history i can see GR qty is ZERO but GR balance is some amount..
So how to clear this GR/IR balance & how to avoid such situation in future
