Use

With validations, you can check values and combinations of values as they are being entered in the SAP R/3 System. As data is being entered it is checked against validation rules that are stored in the Rule Manager. Because validation occurs before data is posted, only valid information enters the FI-SL application component.

You can use a validation simultaneously at different callup points and you can create different dependencies for validating data. For more information, see validation/substitution callup points. Also, you can create validations in the system, even if they are not used anywhere (for example, for future use).

For more information on the additional functions for validations, see additional functions.

Recommendation

To troubleshoot validations, substitutions, or rules, you should use the Simulate and Switch on trace functions.

For more information, see:

Tracing a Validation/Substitution/Rule

Simulating a Validation/Substitution/Rule

Note

As from Release 4.6 there is a new interface with controls for processing rules. If you want to continue using the old interface, make the following settings: In the menu, choose System ® User profile ® Own data. Then choose Parameters and create an entry with the parameter GBK and the value X.
