In some situations when you try to delete a requisition, the following errors appear:
ERROR PRJ-XXXXX: One or more staff members cannot be removed. This may be due to security, committed actuals or booked requisition.
All CA PPM Versions.
Probably is because you have already a requisition created for that role.
When you create a requisition for a role and you booked, the role register remains on team tab with 0 allocation.
Delete a requisition:
1 - Go to Home > Resource Requisitions (In Resource Management)
2 - Search the requisition associated.
3 - Delete the requisition.
4 - Remove the role from Team tab.
Can a resource be removed from a task after posting hours on it?
