Click the Study Configuration main menu icon from the navigation bar. Then, click the Validation Checks
tab.
Select the batch that contains the check.
To prevent a validation check from being executed when the batch is executed, select it and then select Disable Check from the Checks drop-down list.
To re-activate it, select it and then select Enable Check from the Checks drop-down list.
For validation checks that use a custom program, Oracle DMW checks if any discrepant
and secondary columns are marked as Not Used. It prevents you from
enabling a validation check with source tables or columns marked Not
Used. For validation checks that do not use a custom program, Oracle
DMW checks if any of the columns used by validation check are marked
as Not Used. If they are, you cannot enable the validation check. If
any of the tables used by validation check are marked Not Used in
the transformation, you cannot enable that validation check.
