An account assignment reference is required for each subledger position and each class position in a securities account for parallel position management. You can use the account assignment reference to determine the FI G/L account in which the position is to be managed. In contrast to the operative valuation area, the G/L account for a parallel valuation area is not assigned directly to an account assignment reference. Instead, you assign the G/L accounts in the IMG activity Define Account Determination , where the account assignment references are available as possible assignment criteria.
