How to link the closure of the subtasks with the main task workflow

[Kantamneni_Nrupen]

When i create a subtasks for a parent tasks, i want to link the closure of the sub tasks to the main task ( meaning unless all the subtasks are resolved, the parent task cannot be resolved.) How do i create such a dependency

Hi Kantamneni Nrupen,
You can use the Sub-task Blocking Condition as Krister Broman already suggests.

In case you want to display an error message to warning your users why parent issue cannot be transitioned yet, install Workflow Magic Box (FREE) and use their SubTasks Status Validator

See the following documentation page, for further information.

Tell us if  the above proposal solves your problem,
Regards
