Price Difference a/c is getting hit while doing reversal

Hi Friends

Its a Imported Material for which we have released a PO in USD.

Now we are doing MIRO in INR and the entry posted is GRIR Clearing Dr. and Vendor a/c Cr.

But before doing MIGO the user has reversed the MIRO document thro MR8M.

We found that insted of reversing the document the value has gone to price difference a/c.

Can anyone explain why its hitting PRD.

Material was maintained with std.price.

Regards,

Abul
