I have seen some posts with similar issues, but nothing exact to my organization; but apologies in advance if this is a duplicate.

I am trying to figure out how to update the Last Modified Date/Time field when an Activity is added to a case. We do not use email to case, we have our own process in which the support engineer uses the "Log a call" button in the Activity section when information is either sent to the customer or received from the customer.

If that is the only field edited then Last Modified Date/Time is NOT updated. I understand that this is the functionality, but I need to have this field update in order to report on the "Time Since Last Touch" which is a formula I created that compares the Last Modify field with NOW().

I have been told I need an Apex trigger to do this, but as a newbiew to Apex and Salesforce administration tasks I need help. Is this something simple to implement or shoud I just give up?

Any help would be greatly appreciated!
