Hi, just for the benefit in the same boat (no official
training, yada yada). Here's what to do.
Provided you've got the full version of SQL7 installed.

If possible, back up your work first.

1. Start up Enterprise manage
2. Locate your local server
3. Right click on DATA TRANSFORMATION SERVICE
4. Click on ALL TASKS
5. Click on OPEN DTS PACKAGE
6. Locate the package involved and make the necessary
changes

Remember to back up first.
If the instruction aren't exact, my apologies. I'm at home
right now and I prefer not memorise that sort of things.
There's better things I could be using the space for.

All the best.

Yours truly,

Ka Kwok
