updating database with import script in multi-user

[ggh]

I have a main database (A) that's related to a demographic database (. The demographic database gets its data from an excel spreadsheet. The two databases are hosted by filemaker server and accessed through FMP6 desktops.

I've written a script that imports the records into B from the excel spreadsheet, and I'm trying to determine the best way to trigger the script. Right now when A opens, it also opens B and triggers the import. Database B will have well over 2000 records, but the script will only be synchronizing the data. On my desktop this approach works beautifully. I'm concerned that it will be slow as sin in a multiuser environment. Has anyone done something like this?

My other thought was to use Events to trigger the script in the middle of the night (it really only needs to be once a day).
