Use the Merge or Delete WBS Element(s) dialog box to confirm that you want to delete a WBS element. Also, if the WBS you are deleting has activities associated with it, choose one of the following options before clicking OK to confirm the delete action.
Delete Element(s): Deletes the selected WBS element and all activities assigned to it.
Merge Element(s): Deletes the selected WBS element and reassigns its activities to the WBS element.
Note
- These two options also appear if the WBS has both activities and planned resource allocations. However, resource allocations cannot be merged. Regardless of the option you choose, the planned resource allocations are deleted. For this reason, when a WBS has planned resource allocations but no activities, these options do not appear.
