Server-Side Import From .fp7 in Documents folder

Sorry if this is already known, but I couldn't find this information anywhere and stumbled upon it.

FileMaker's KB says this: Importing/exporting directly to and from another FileMaker Pro file is not supported via a FileMaker Server scheduled script.

However; I found that if you have a .fp7 file in the documents folder and attempt to import from it, the error that came back was 212 (Invalid user account and/or password; please try again). Even though I had matching account credentials in the files with full access, as well as running the scheduled script with the same full access account.

What did work was when I modified the data source file (in the documents folder) to grant the Guest account full access, and set the file to open using the guest account [File-->File Options]. Now when I run the scheduled server-side import it works!

Obviously not the ideal from a security standpoint, but interesting to know it’s possible.
