I can at least say this:
If you are editing a Job which is related to a Customer, OR
You are viewing a Grid of Jobs, THEN
any EDIT OBJECT or VIEW OBJECT command that you can attach to a Button will EDIT OR VIEW the JOB, not the CUST.
(this is what you have found, no doubt)
A Job can be related to a Customer, a Sales Rep, a Territory, a Plant Location, etc etc.
So what "easier" automatic way can Aware know of when you want to see details about one of those Relations?
Yes, it might seem "over kill" or "extra work" to have to go make a Process with 1 line in it - and you may never use this process anywhere else.
But doing in a process also allows you to add intelligence to:
- Check a value before going to the form. Maybe Display a MESSAGE first (like "Account is past due"),
- Based on the logged in user, EDIT Customer USING (a specific Form based on user, or Customer type, or anything)
So, its not that much work to do it via Process. Spend the 30 seconds and some day you'll actually take advantage of some Logic in the Process.
