Deleting Writeback Data and Write-Disabling a Cube
You can delete the contents of a cube's writeback table by using the Delete Writeback Data dialog box, which is accessed by right-clicking a write-enabled cube from the Analysis Manager tree pane.
Important When you delete the writeback data for a cube, you also write-disable the cube. All Unrestricted Read/Write policies and read/write permissions for the cube's cells are disabled, and end users will not be able to change displayed cube data. (End users with disabled Unrestricted Read/Write policies or disabled read/write permissions will still be able to browse the cube.) Read and read contingent permissions are not affected.
