A moov configuration for a specific client allows you to override the standard transformations if necessary. For example, you may have a plan with John Hancock where the Safe Harbor Employer Match value needs to be mapped to the 'SHMAC' field instead the standard John Hancock 'SHMAC' field.
To override a transformation on the client moov configuration, click moovs on the left-hand navigation menu and select the moov associated with the configuration.

Select a client configuration under the moov configuration section on the right-hand side.

Click Next in the lower right corner of the 'edit configuration' page.
Under the Action - Transform step, click the Transformation Overrides panel and click the ADD button.

For our John Hancock example, we will first need to remove the mapping on the SHMAC field.
To remove the mapping, select field 38: SHMAC from the dropdown menu and click the 'ADD OVERRIDE' button.

On the New Transformation Override page, hover over the 'Remove Separators Leave Decimal Point' Transformation rule and click the trashcan icon to delete this rule.

Click on the Input fields dropdown and uncheck the Current Payroll Safe Harbor Employer Match and then click OK.

Under the Action - Transform step, click the Transformation Overrides panel and click the ADD button.

In our example, we now need to map to the ERMT1 field. Select field 38: SHMAC from the dropdown menu and click the 'ADD OVERRIDE' button.

On the New Transformation Override page, click on the Input fields dropdown and select Current Payroll Safe Harbor Match.

Click on ADD Rule and select the rule Remove Separators Leave Decimal Point and then click OK.

To complete the transformation override, click the NEXT button in the lower right corner, then click the SAVE button on the summary page.
