allow populating a field only when a condition is fulfiled

[gowri goli]

We have a requirement that users can update the root cause field only after the story moved to 'Ready for Approval'. This is to prevent users entering any reason just so the issue is populated without doing the proper research and fix.

Hi @gowri goli

I recommend using a transition screen where you can add the field only when it transitions.  

See this tutorial: https://www.youtube.com/watch?v=RIKYX-z4meM

1. Create transition screen

2. add it to the workflow transition and make the root cause field mandatory with a validator

3. Make the root cause field only viewable and not editable in the edit screen.

I hope this helps.
