When to validate record in a master detail form?

This is a rather complex issue, because it depends on the design layout. There are a lot of ways to design a master-detail form. I'll show you three of them.

Master Single Record
Detail Tabular

Now you can move between the master and detail without firing unlockRecord in the master.


Master MRO (1-1)
Detail Tabular
In this case you will trigger unlockRecord when you leave the master


Master MRO (1-1)
Detail tabular
Check Nested at the left side of design layout.

Now you can move between master and detail without triggering UnlockRecord.

So it's up to you to pick a design layout, that gives what you want. And I think you can find some other interesting aspects on when to use Nested with a MRO.
