In the FI-SL application component, you use the OR (disjunction) operator when you want the system to check that at least one statement is true before using the data.
The following graphic uses a truth table for the OR (disjunction) operator to determine if transaction data should be substituted.
If the transaction is for account 500000 or for cost center 150, then the combined statement is TRUE and the data is substituted. If the transaction is not for account 500000 or for cost center 150, then the combined statement is FALSE and the data is not substituted.
