Right-click context menu for some tasks does not provide Delete option
ITMS 8.7
Any task which has currently running incomplete task instances won't allow deletion.
Behavior is by design. Tasks cannot be removed if there are incomplete task instances.
The following query may show this condition:
EXECUTE tmCanDeleteTask @taskGuid='71f87ec3-89df-48a5-a4c8-455a64488b7f'
1 - True 0 - False
