Changing an existing work breakdown structure (WBS)

1. Open the Estimate WBS Settings or the Database WBS Settings window.

   • On the ribbon, click the Data > WBS.
   • In classic view, click Database > WBS…

2. Select the source.

   Note: If both an estimate and a standard database are open, the Estimate WBS Settings window appears initially. (If only an estimate or a standard database is open, you cannot switch to the other option.)

   • To change a WBS code in the current estimate, select Estimate.

   • To change a WBS code in the standard database, select Database.

     Note: Changing WBS codes in the standard database does not affect existing estimates.

3. Change selected WBS codes as necessary.
   • To delete a WBS code, select the row, and then click [Delete].
   • To renumber WBS codes throughout the standard database, click [Move].
   • To remove all references to the WBS codes and their associated values from items, addons, spreadsheet sequences, and assemblies, click [Clear All]
4. When you finish making changes, click [OK] to save them.
5. Click [Close].
