When adding a DeptID Comp Adjustment in HCP, you can select any account from the available list.
Once the DeptID Comp Adjustment is created, the Distribution elements (DeptID / Entity, Salary Account, Fund or CF1) CANNOT be edited.
If a change is needed, right-click and select Add a DeptID Comp Adjustment that has the correct Distribution elements and then zero out the values from the incorrect DeptID Comp Adjustment as needed.
