"Cannot delete projectApprover (X) for project (Y). This project requires a primary projectApprover."
When deleting a project approver, you may get the following error:
When importing projects via Project Administrators import, if the Approve Time column is ‘Y’ and the Role column includes projectApprover, then there has to be a project approver imported to the project.
If there is a project approver set on the project with Approve Time or Approve Expense checked, then that project approver cannot be deleted via the Project Administrators import.
In the import file, set the Approve Time column to ‘N’ or specify a valid project approver in the username column.
In the user interface, uncheck the Approve Time box or import a row with the Approve Time column set to ‘N’ before (above) the row attempting to delete the project approver.
