| validation (EC-CS) |
A process of checking values and combinations of values as they are entered into the SAP System.
Entered values are checked using a user-defined Boolean statement (this is a prerequisite). If the statement is true, the SAP system validates the data using a second Boolean statement (as a check).
Whether the entry can be posted depends on the message type.
Validation occurs before the data is posted so that only valid data is posted.
