In order to add FieldMaker fields as columns in your data grid, it must be  Full view, not Optimized. This is because Optimized views look at only the primary table for the module you are in.  Full views allow you to add fields from multiple tables. Although you don't have to do anything to link the tables, the fields from the FieldMaker table won't show up on the Columns or Selection tabs unless you change to a Full view.
To change to a Full view:
  1. Click on the Views tab inside View Settings
  2. Click on the Settings button on the right
  3. Change the Type value from Opt to Full
  4. Click OK  
  5. Click Save  
  6. Your FieldMaker fields should now appear
