Pack reference designators when packing structure elements

Learn how to control whether reference designator values are packed when structure elements are packed. While packed reference designators cannot be edited, business users can modify them for unpacked lines. You can specify if the system must pack the reference designator values while packing structure elements. You can do this using the BOM_Enable_Ref_Designator_Value_Packing preference. Because this preference is set to true by default, the system packs the reference designators. For example, consider that an element occurs six times in a structure. The reference designator values for these occurrences are C1, C2, C3, C6, C12, and C13. When a user packs this element, the reference designators too are packed. The Ref Designator column shows the values as C1-C3, C6, and C12-C13. The user cannot edit the reference designators of packed lines. For the lines that are not packed, the user can modify the reference designator values irrespective of the value set for the preference.
