Hi @shashanksha 

The post button comes with "Activities(filtered) Formatter", any change with that may impact other module form as well. The best you can try a business rule on table with applied condition on Work Notes/Additional Comments, if it matched with desired condition value you can allow or abort the change.

You have to make changes on the POST button. Go to System Definitions>UI Actions search for the POST  button related UI Action and then write a script accordingly.

Hello @yuvarajkate ,

We dont have any POST ui action in Ui actions.

Not possible to do this, best thing you can try is to disable post button that too requires DOM manipulation which ServiceNow doesn't recommend but you can give try. My suggestion is to not to do with this requirement as this requires changes to OOB behavior which again ServiceNow doesn't recommend. For DOM solution try below.
