Venkatesh --
Amazingly enough, there IS a way to do what you wish. Before you do this,
however, I am assuming the following about your environment:
1. You saved your original baseline in the Baseline set of fields.
2. After a change control procedure, you saved your new baseline in the
Baseline 1 set of fields.
3. After another change control procedure, you saved your new baseline in
the Baseline 2 set of fields.
To restore a baseline, you would need to do a two-part operation. First,
you would need to back up the original baseline (saved in the Baseline set
of fields) into one of the additional 10 sets of Baseline fields (Baseline1
through Baseline10). Then, you would need to copy the desired baseline
information in Baseline 1-10 into the Baseline set of fields. Here's how:
1. Open the project in question.
2. Click Tools - Tracking - Save Baseline.
3. Select the Save Interim Plan option.
4. Click the Copy pick list and choose the Baseline item from the list.
5. Click the Into pick list and choose the first available Baseline set of
fields (Baseline 3 in your example).
6. Make sure the Entire Project option is selected and then click the OK
button.
The operation "backs up" the baseline information in the Baseline set of
fields into the Baseline 3 set of fields. Next, complete the following
steps:
1. Click Tools - Tracking - Save Baseline.
2. Select the Save Interim Plan option.
3. Click the Copy pick list and choose the Baseline 1 item from the list
(this is based on your example).
4. Click the Into pick list and choose the Baseline item from the list.
5. Make sure the Entire Project option is selected and then click the OK
button.
6. When prompted, click the Yes button.
The above set of steps copies the Baseline 1 information into the Baseline
set of fields and calculates all variance in the project based on this new
information. If you want to use this process, you will need to take a very
disciplined approach to managing baseline information to make sure you don't
lose any of your original baseline information in any of the Baseline sets
of fields. Hope this helps.
