Why is Validation and Substitution rule important?
As the user sets the Validation rule, it checks the validation rule defined on specific fields data. When user is trying to post the transaction and enters data in that specific field, which violates the validation rule, system throws an error message for the user and it will not allow the transaction to post.
It will succeed to post the transaction only when the data is posted in that specific field as defined in the validation rule. It helps to avoid wrong entry at initial stage of posting the transaction.
Whereas Substitution rule is set up to substitute the data immediately upon the entry made. As the user enters the value, system validates according to the prerequisite defined by the user. If the prerequisite rule is met, the system replaces the value entered with other values.
With SAP S/4HANA Cloud 2005, The Manage Substitution/Validation Rules app for JVA is enhanced with the new comparison operator Matches and the new substitution type Table Lookup.
The Matches operator can be used to match a string-type field value against a regular expression.
The Table Lookup substitution type allows user to choose a source field from a custom business object and uses its value to fill in the target field.
