Creating a Setup Matrix
       Use the Setup Matrix form to define the
         required setup time for changing a resource's setup from working on one type of item to
         another.
   
      Just as you can define the Setup Basis on the operation for specifying when to apply setup time, you define the Setup Basis for the setup matrix to apply its setup time. A setup matrix can be based on the item, setup group, or resource group changing.
Note: You may 
 only specify setup matrices that match the Setup 
 Basis specification on the Job Operations 
 form. For example, if the current job operation record specifies Item 
 as the Setup Basis, then, in the Setup Matrix field, you may only choose a 
 matrix whose Setup Basis specification 
 is also Item.
