Problem related to debit note and GRN

Question

Hi People
I am abhishek working as a SAP consultant in a Garment manufacturing firm
There was a PO made for some threading cones of different size
for example
one cone with 100 meter length and second cone with 200 metre length
in PO ordered qty was in metres
100 thread cones of 100 metres = 10000 metres
10 thread cones of 200 metre length  = 2000 mtrs
total metres is 12000 mtrs
price per metre is same for both the cones
now the guy who made the MIGO considered it as all the cones made are of same type and made the GRN as
110 cones recived  ie 110 * 100 = 11000
and we sent the vendor a debit note of 1000 mtrs
all the payment were carried out and the check has been sent to vendor as well
now the vendor came back and sai he sent all the order in PO correctly 
what should be done now?
i dont want to cancle the debit note and invoices and make a grn of remaining 1000 mtrs
can any one suggest me wht can be done ?

Answer 1

you have to pay to the vendor. its the mistake from the data entry point of view. either you have to cancel and recreate the entry or you have to pay. that it.
