How to prevent transition according to Sub-Task type and Assignee

[GabrielJ]

Hi,

I want to prevent a transition at Parent level if SubTask, with Sub-Task Type (custom field) = X and Sub-Task Assignee is "unassigned".

How to do it?

Thanks, Gaby

Hi @gabyj,

You can implement that validation in parent's workflow using "Boolean validator with math, date-time or text-string terms" with the following boolean expression:

%{nnnnn} = "X" IMPLIES %{00003} != null

replacing nnnnn with field code for custom field Sub-Task Type.

Note that %{00003} is field code for Assignee.

Thanks, I will try it. But how the validation understand %{00003} != null represents Sub-Task "unassigned" ?

For learning purposes, how to use the following function in "Boolean validator with math, date-time or text-string terms" ? :

count(filterByPredicate(subtasks(), ^%{nnnnn} = "X", ^%{00003} != null)) = 0

Hi @gabyj,

Sorry, I made a mistake. The boolean expression you should use is this one:

count(filterByPredicate(subtasks(), ^%{nnnnn} = "X" AND ^%{00003} = null)) = 0

replacing nnnnn with field code for Sub-Task Type custom field.
