You use this parameter to control if the system compares purchasing documents in a foreign currency on the key date specified and which exchange rate it uses to do this.
The following entries are possible:
'A' - The system makes no comparison, that is, all documents are included in the market price determination at their original rates (default setting).
'B' - The system compares prices with the middle rate. On the key date specified, if the middle rate leads to a lower price, the system uses this price for the market price determination instead of the original exchange rate.
'C' - The system compares the lowest value from among the selling rate, the bid rate, and the middle rate. On the key date specified, if at least one of these exchange rates leads to a lower price, the system uses the exchange rate that results in the lowest price for the market price determination instead of the original exchange rate.
D' - The system always uses an exchange rate for the key date specified for the market price determination. This is the bid rate, the middle rate, or the selling rate, depending on which one results in the lowest price.
