The Project manager is trying to set the assignment finish date for a resource that has 0 ETC and 0 actuals against the particular task. When you try to remove the resource from the assignment, you receive the following error:
PRJ-07582: One or more assignments cannot be deleted. This may be due to committed assignment actuals when trying to delete a resource from a task.
Is it possible to unassign a resource from a task / delete a task if actuals / time has been posted for one or more assignments?
Release: All Supported
Component: Clarity Project Management
It is not possible to delete assignments with posted actuals. Clarity does not allow actual units of work to be deleted on an assignment or task with submitted, approved or posted actual units through timesheets. If you try to delete an assignment with actuals, you will see the error noted above.
You also cannot remove a resource from a project that has submitted, approved or posted actuals through timesheets or from within the Investment Team
NOTE: If you delete the time periods where the actuals were entered, ALL associated timesheets are deleted. If you do this, you will be able to remove the resource from the project, and delete the task. However, deleting the time reporting period also deletes ALL Timesheets for that time period, so be careful that you do not delete data you still need. See Remove resource from task after posting hours on it for more details.
