Adjustment of GR and IR quantity after GR and IR had been done.

Question

Hello experts,
my business scenario is like that.
my purchasing material is very minute.
so initially when we go for GR and IR, we don't check it physically.
but when we  use the material physically, we check it physically and if there is any mismatch in physical quantity and my system quantity.(GR /IR).
But is it possible in SAP.
because when i go for return delivery it is asking deficit of PO IR QUANTITY
EXAMPLE:
PO QUANTITY: 200 PC
GR QUANTITY: 200 PC
IR QUANTITY: 200 PC,
AFTER physical checking we found that we received only 190 pc,
so we for credit memo for 10 pc.
now my ir quantity becomes 190 pc.
then i go for return delivery for 10 pc.but it didnt allow me to do this...the error is coming like this..
Deficit of PU IR quantity 10 pc
can anybody tell me how to overcome this issue.
regards.
raghu.

Answer 1

you can always make return to vendor for the quantity you have not received.
but once postings is done you cant reverse the posting through lot.
for this purpose , it is suggested to use inbound delivery
VL31N
after inbound w.r.t inbound number you can make GRN after counting the quantity of the material .
So GRN is made in correct received QTY.then process Quality lot and so payment also happens smoothly without credit memo.
moreover once IR is done for whole qty you can only accept the material not other way because credit memo is a accounting document which can be raised for many purposes like change in pricing, duty., etc., not only quantity deficiency...
