What is the most effeciant way to send a record from one database to another database on the same server? I Have tried creating a relationship between them, but it slowed the system down a lot, when they were joined. The import/export method seems to work, but not sure how to trigger the import from the other database.

I seem to remember a white paper on a related matter some time back, that indicated an import to be the most efficient way to move data. To trigger the import script from another database, you'll need to have a script in both files. The script in the destination file will do the import, and the script in the other file will call the other script as a sub-script.

That is to say, when you add a "perfom subscript" step, it gives you the option to call a script in another file.

More detail would help. For instance the speed hit does not make much sense and relationships are the very foundation of FileMaker.

So we would need to know more about how you set up the relationship. Also, since you can make a table occurrence for file 2 inside file 1, you do not really have to do anything in file 2 to get the data over there.

And what is behind the request? Do you really need to move data? Or just "see it" across a relationship?
