Rephrase the problem: A supervisor wants to keep track of people. The people move around independently and the supervisor has no way to track them.
The people need to phone home to the supervisor regularly. The people change location but the supervisor will always be (and needs to be) at the same place.
It sounds as though you want some sort of synching solution. There are a couple around. EasySynch comes to mind.
I've already written scripts to handle checking out each database, and I'm working on the check-in scripts. I would just prefer to not have to put copies of each script in all my databases. I just want a simple script in each database that executes the Save a Copy as command, which I can then execute from the script in the parent database using the Perform command. I'm still stuck, however, with the manual process of having to use iTunes to download the database copy to FileMaker Pro on my iOS device.
Whether this proves to be a workable solution or not, I'd still like to know if it is possible to create views into multiple child databases from a single record in the parent database.
By the way, I Googled EasySncyh, and found something called FMEasySync. Is this what you're talking about. It needs a server to work. I'm just running FileMaker on my MacBook Pro.
