On my case I have a subgrid of a custom entity called service items. Case is a lookup value on that entity. When I create a new service item I want to automatically set the "name" value for the user using this format "ticketnumber - service item". I am attempting to do this using javascript but so far I can't seem to get the value of the ticketnumber or figure out how to pass it in. Getting the name of the service item works fine. How can I get that case number (ticketnumber) so that I can concatenate that value?
This is kind of urgent so any help would be appreciated. Thanks!
