This is a great feature. However the PSOS does have some limitations. You can't import from another Filemaker database. I thought there were some import/export restrictions with Excel documents on the server as well. Standard text files work pretty well, and as you mention, it is very fast.
Yes for imports from another FileMaker database we just export to the temp directory and import it back it - its an extra step but if you really need to import it can be done. As far as import/export restrictions ... I haven't done exporting and the import I did seemed to work just fine. So not aware of what other restrictions that might be there.
And obviously moving cautiously is always a good idea in this new area and lots of testing as you don't want to execute a script that gets into an endless loop.
I'm waiting for the authentication error to be corrected. Most of our solutions use muliple files. Then I'm all over it.
Thanks for your great presentation at FMDiSC a few weeks ago!
You are most welcome - would love to hear from you to see how it works out.
