How to set workflow validators from one status to other when status change set to all

[Prathap DL]

We have workflow which user can change status from any to any. Now i want to add workflow validator from one state to other. How to do that?

For Ex: Workflow

Open--->All

InProgress--->All

Closed--->All

deferred--->All

Reopened--->All

With above example user can change the status from any to any.

Now i want to add validator from "Closed" to "reopened" only. the validator should work only from "Closed" to "reopened" only.

Hi Prathap,

You would need to add another transition from Closed to Reopened. In my opinion you should get rid of the All transition to Reopened - that doesn't look like it should be something that is implemented because you wouldn't go from any of those other statuses to Reopened - just from Closed.

Hi John,

Thanks for the Reply.

I just gave the example workflow. Actual workflow is different and user will go from any state to any.

So, we need the exact scenario in order to provide the best answer.

Hi John

If you look at the below Transition diagram, User can travel from any state to close. Now i want to add validator from "[QA] Updating DHR" to "Closed". whenever transition is moving from "[QA] Updating DHR" to "Closed"
