Hi Chris.

>I suspected that the ADDs were taking place before the DROPs. That explains the error. Any chance of a 'DropBeforeAdd' switch? Is that feasible?

Try this: near the end of SDTMgr.HowToSyncTable is this statement:

if laToDo[lnI] <> 'drop column'

Change it to:

if laToDo[lnI] <> 'add column'

and see if that works for you.

>Anyway, thanks for a great product. Highly recommended.

Thanks for the kind words.
