Validation Groups
Sometimes you may want to run a group of validations against one or more records at the same time.

For example, Trading Partner X may have a total of 125 validations while Trading Partner Y has a total of 143 validations, many of them in common with Trading Partner X.
MDM supports this by allowing you to assign each validation to one or more validation groups. A validation group is a set of validations that you can run at the same time just by invoking the name of the group rather than the name of the individual validation.
When you run a validation group against a set of records, it is as if you have run each individual validation in the group, and you get an individual success or failure result for each validation for each record.
To add a validation to one or more validation groups:
1. If necessary, click on the Validations tab to make it the active tab.
2. In the Validations pane, select the validation you want to add to the group(s).
3. In the Properties pane, double-click on the Group cell.
MDM opens a dual-list drop-down hierarchy control for multiple-item selection, as shown in the following figure.

4. Move one or more groups between the Available Groups list and the Selected Groups list.
5. Press Enter or click on the up triangle to close the drop-down control.
6. To save the validation, right-click on the Properties pane and choose Save Validation from the context menu, or press Shift + Enter.

Validation groups allow you to organize large sets of related validations, eliminating the likelihood of forgetting to run any of the individual validations in the group.
