Hi Gaurav
In that case, post the GR for the PO where you did not do GR, and similarly do the IR for the other PO
In that process, the GR/IR would be knocked off completely
Now comes, the extra Stock and Vendor LIability that you would be generating in the above process
Charge off the Stock to CC
CHarge off the vendor liability by Dr Vendor Cr a P&L Account
Thats the simplest way i can think of
