if a value is selected on a field can prevent to move to status done until we change the value?

[Ariel Gavillon]

Hi,

I'm trying to figure out how to configure or make a rule, that prevent moving to status done if a specific value is selected on a field. 

In my case i have a field with 3 different values: None, Required, Done.

So what i'm trying to do is, if i select the value Required on Status New i can't move the ticket to Status Done, must go throw Status In Progress.

Any idea how i can do this?

Ariel,

yes, of course, you can implement this with a workflow validation.

In the validation i don't see a option for the value, just for a required field

Are you using cloud or server?

Also, is the value set before you attempt the transition or on the transition screen. If before, you can use a condition test

Thx @Joe Pitt, actually that's what i was looking for.

I use the condition Value Field, 

Chose the field i needed, with condition !=, the correct value and Comparison Type String

and work how i expected.

Thank you very much!!
