Deleting Objects with References

When Delete is Disabled

If an object appears unused but can't be deleted:

  1. Search References
    • Use Find Results panel
    • Enter object name
    • Review all locations
  2. Remove References
    • Double-click each reference
    • Delete or replace usage
    • Repeat until clear
  3. Final Deletion
    • Return to object definition
    • Delete from main table
    • Or delete from Unused Objects
