In a structure, you can set the quantity to be automatically updated as per the number of reference designators specified by a business user. You must do this before the users create or import structures. To set the quantity to be automatically updated, you can use the BOM_Enable_Quantity_Validation_Against_Ref_Designator preference. When you set the value of this preference to true, Teamcenter validates that the quantity and the reference designator list are consistent for every occurrence. In addition, when the reference designator list is modified by the user, the quantity is automatically set based on the number of reference designators specified by the user. For this validation to work, you must also set the value of the PS_Reference_Designator_Validation preference to true.
