Edit joined checkout

[DarrenWiens2]

Is there a fundamental problem with editing a checkout (or parent database) that is joined to another feature class?

Background: we have a personal SQL Express database as the parent database. Checkouts are distributed from it. In one of the checkouts, two columns were added and populated (yes, I'm sure that makes some of you cringe). Of course, on check-in to the parent, those new columns are ignored. Is there any way to get those columns into the parent db? I am allowed to create the new columns in the parent, but once I join the checkout to either the parent or a new checkout in order to join and transfer data from column to column with the Field Calculator, the Field Calculator is disabled. Any help is greatly appreciated!

The Replica schema synchronization tools can help you here
http://resources.arcgis.com/en/help/main/10.1/#/Schema_changes/003n000000wn000000/

First you will use the Compare Replica Schema command or gp tool to compare the parent and the checkout replica gdb's schema.
You can then import the resultant schema differences to the parent and apply the schema changes (addition of 2 columns)
Then when you sync the Checkout itself - the values that were populated in the Checkout will come in as part of the sync.

Thanks,
