Advise how to set GL account for GR/IR difference due to different exchange

Question

Hi Experts,
You could find that price in GR and IR is the same, but the exchange rate in IR(32.395) is differenct from exchange rate in GR (32.37000).
There are some line items of Price differences in inventories from procurement (GL 490400) in the accounting document of GR, but they are derivative from differenct exchange rate rather than price differences.
So, we would like to change the configuration to let the exchange rate differences posted to GL account of income or expense from exchange rate differences (GL 396000/796000), other differences posted price differences in inventories from procurement (GL 490400).
Kindly advise.
Thanks.

hi
Differences due to exchange rate rounding, Materials Management (KDR)
An exchange rate rounding difference can arise in the case of an invoice made out in a foreign currency. If a difference arises when the posting lines are translated into local currency (as a result of rounding), the system automatically generates a posting line for this rounding difference.
Exchange rate differences from lower levels (KDV)
In multi-level periodic settlement in the material ledger, some of the exchange rate differences that have been posted during the period in respect of the raw materials and semi-finished products used in the manufacture of a semi-finished or finished product are debited or credited to that semi-finished or finished product.
Exchange rate differences in the case of open items (KDM)
Exchange rate differences in the case of open items arise when an invoice relating to a purchase order is posted with a different exchange rate to that of the goods receipt and the material cannot be debited or credited due to standard price control or stock undercoverage/shortage.

Price differences (PRD)
Price differences arise for materials valuated at standard price inthe case of all movements and invoices with a value that differs from the standard price. Examples: goods receipts against purchase orders (if the PO price differs from the standard pricedardpreis), Goods issues in respect of which an external amount is entered,invoices (if the invoice price differs from the PO price and the
standard price).
-   None     for goods and invoice receipts against purchase orders
-   PRF      for goods receipts against production orders and
         order settlement
-   PRA      for goods issues and other movements
-   PRU      for transfer postings (price differences in the case
         of external amounts)
