Is your temporary index an IDX or a CDX? I had some nasty problems that bit me a while back using a temporary IDX, and will never use them again! Tableupdate failed when I had an IDX for the table in a different private datasession.

IAC, this may be more of a change than you want to make right now, but I'd use an updateable view for this. You can create a CDX tag on the view.
