Process Overview for Returns for Purchase Order

Dear Friends...

Guide me through the following.... and suggest me if I am wrong.

1) I have created a PO for 10 Pc for a particular raw material (PO No: 4500017787), then with reference to this PO I have done

goods receipt.

*Note: I have not yet done Invoice verification

The accounting entries created are as follows...

Stock A/C GR/IR A/C

10000 Dr 10000 Cr

2) Now I have created the Returns for PO for 2 Pc (PO No: 4500017790). Then with reference to this PO I have done goods

receipt. Now with reference to same PO I have done Invoice Verification(Credit).

The accounting entries created are as follows...

Stock A/C GR/IR A/c Vendor A/C

2000 Cr 2000 Dr 2000 Dr

2000 Cr

This is what I have done...

Now my question is that how should I invoice the customer for the 1 st point

Regards...
