Validation Result Columns 

When you press OK to clear the warning dialog that reports the failure of one or more validations run manually or one or more warning validations run automatically, MDM adds a Validation Result column to the Recordsgrid indicating whether each record succeeded or failed for that validation, as shown in the figure below.

Each Validation Result column is named with the validation name in square brackets ([]).

When you move the mouse pointer over a validation failure, MDM pops up a tooltip with the error message associated with the validation, as shown in the figure below.

You can sort by each Validation Result column to group records that failed the validation, and edit them to correct the error.

When you test a multi-valued field or text attribute for equality to a value or values, “=” means “identically equal” (that is, the same set of one or more values in exactly the same sequence).

NULL interpretation differs between validations and search. Specifically, an expression that returns a NULL result evaluates to: (1) TRUE for validations (validation SUCCESS); and (2) FALSE for search (included in the search results for the is FALSE operator).
