Hi Thomas,

I'm not at all certain how you are using datapump to do that
anyway. I'm not up to date with latest versions of IBO, but
I thought datapump was a one-table-at-a-time sort of thing?

I'd probably do it outside the pump with cursors and dsql,
perhaps with the master dsql using a stored proc or execute
block that returns a true/false to indicate whether it
inserted or not, so you know whether to process the detail
for that row.

Probably not all that helpful, I just didn't like leaving you
to the sound of crickets echoing in the empty hall. :-)
