I have created the WBS element with business area. Then created the PR against that WBS element , converted the PR's to PO's.
Now I want to remove the business area from WBS element.
Now as Business area field become grayed out hence I canot remove the Business area from WBS element.
Hence I have cancelled the PO's then Cancelled the PR's. So now there is no actual cost & no commitment exists against the WBS element.
But still Business area field is grayed out for that WBS element.
Could you please let me know how to remove the business area in this case ???
