I am creating a DTS package in SQL 2000 with SP3. (Same issue in SP4)

This package has one "Execute SQL task". The task calls a stored procedure
which takes parameters. Using parameter mapping, I try to map the global
variables already defined to the parameters for my procedure. No problems
while mapping. When I click OK and come of edit mode, I loose the mapping. Is
there any known issue? workaround / fixes?

Ironically it does not happen on all the SQL servers I use. It is not a
consistent issue.

Thanks for any help.

Well guys, I found a fix myself. Re-installing SQL Client tools did the trick.
Don't know if this was a problem only for me. But since it was identical on
more than one server, I am guessing not.
