How can I make Work Notes mandatory if anything is changed on an incident form?

[Sorren Day]

I'm trying to find a way of making it so that if any user looks at an Incident and changes any aspect of it, the 'Work Notes' field becomes mandatory as a reminder for them to write and record what they have done.

I have seen other people asking how to do this for a specific field change rather than any or all changes. The solution given to them is to use an onChange Client Script. I have looked at these and I can see how I would get it to make the work notes mandatory if the priority or assignment group (for example) is changed, but that's too specific for my needs.

Any suggestions?

This looks like it could achieve what I want, except I can't see how to state that Work Notes becomes a mandatory field when trying to update an Incident.

I am not sure, whether we can do via client script.

Best you could do is a Business Rule that checks for the State changing to Resolved, and if work notes is empty aborts the update.  Unfortunately this is ugly to the end user because they click Update and then are told something is wrong, instead of requiring Comments before they can even click Update.

Hmm, ok I will have a bit more of a play about. Thank you for your help.
