You should be able to accomplish the ask with a Business Rule. You'll want to check advanced, make it a before BR. Set your conditions and on the actions tab select abort and add message. See below screenshots
Hi @jayaprakash1998,
You can achieve this through UI Policy, write a UI policy like below on Incident table.
And you can write the alert in the Execute if true like below.
And when ever you try to change the state to on-hold and the on-hold reason is Awaiting problem, It will show the alert on the Incident like below.
If you want the problem field also to be mandatory, you can write UI policy action under this making the problem field mandatory to true.
Mark this answer as correct and helpful if it solves your issue.
