SOP and MC

The following describes changes made as a result of SOP MC. The focus of this discussion is on a non-MC SOP transaction. In SBF, multiple currencies are not supported.

Currency Index-This should be the 'Functional Currency Index' of globals for non-MC SOP transactions.
Rate Type ID-This should be blank for non-MC SOP transactions.

Exchange Rate-This should be blank for non-MC SOP transactions.
Exchange Date-This should be blank for non-MC SOP transactions.
Time-This should be blank for non-MC SOP transactions.
Rate Calculation Method-This should be blank for non-MC SOP transactions.

"Originating" values-The originating currency values (typically in the format "Originating ") are the primary currency values used for a SOP transaction. The corresponding functional currency values (typically in the format "") are calculated from the corresponding originating currency value. For a non-MC SOP transaction, the originating and functional currency values will be the same. Leaving either the originating currency value or the functional currency value blank for a non-MC SOP transaction is not allowed. If the value is not being used, both the originating and functional currency values should be blank.

Tax Date - Required for VAT.
Denomination Exchange Rate - Required for Euro Triangulation.
