OBYC KDM, KDW, KDV and KDR operations

Question

Hi,
I have a problem with differenciating the following OBYC operations:
- KDM - I think it should be used for GR/IR exchange rate differences /
            or is it used for Material Ledger Single level exchange rate differences
- KDR - I think it should be used for GR/IR exchange rate rounding differences
- KDV - I think it should be used for Material Ledger Multi level exchange rate differences
- KDW - is it used for GR/IR exchange rate differences?
If you could please tell me which operations shoud be used for Material Ledger exchange rate differences for single and multi level.
Best wishes,
Karol

Answer 1

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.
