Running SQL 2005 SP4
I am trying to use the Import/Export Wizard to copy 40 table from Server A to Server B. After selecting all the tables, I set them all to "Delete Rows In Destination Table" and "Enable Identity Insert".
I deselect "Optimize for Many Tables" so I can save the package & edit it later.

When I run the package as the last step in the Wizard, it fails and tells me I cannot insert a duplicate - Violation of primary key.
There are no duplicates in the source. "TableA" only had 1 record anyway !
When I run it again, "TableA" completes cleanly, but now I get an error that "TableC" has duplicates.

It seems that the truncates and copies are running at the same time, so sometimes a copy is happening before the truncate and throws an error, and sometimes after the truncate and completes normally.

Any thoughts on this crazy situation ?

EDIT: I saved the package, opened it in BIDS, and see that only 4 of the tables have a "truncate" statement even though in the GUI, they all have "Delete Rows In Destination Table" checked ?!?!? WTF ?!?!

EDIT2: I didn't manually check "Delete Rows In Destination Table" on each table. I highlight all the tables, then choose "Edit Mappings" and check "delete" 1 time and it applies to all the tables ..... except I guess it doesn't really apply to all the tables, just LOOKS like it does, since the check mark is there, but it does not execute.

Is there a workaround for this bug ???

Yes, manually set it for each table

Or you can just create truncate table statements for each table and paste it into the package.
What you do yourself, is often better
