Percent complete issue

Hi,
I’m using P5.
I have a schedule (baseline, let’s call it Schedule A) wherein it was the orignal schedule submitted to the client. In this schedule resources are not loaded and it is simply showing the Start / Finish date of every tasks and the work/units (budgetted units) per task.

Now, I have an actual schedule (let’s call it Schedule B) which we are now using to enter the actuals.

Question is if I want to know our progress in comparison to Schedle A, how to do it? Say today is June 6 and each tasks on Schedule B has some percent % complete how to compare it to Schedule A?

Just like this....
Schedule A:
Task 1: Build wall, Start (May 30), Finish (June 7) = meaning by June 7 should be 100% complete

Schedule B:
Task 1: Build wall, Actual Start (May 30), percent complete only 10% (today is already June 6)

So, how to know the percent complete of Task 1 in Schedule A as of June 6? Like asking a question, if our actual percent complete is 10% as of June 6 (as per Scheudle B), how many % complete we should have been as per the target on Schedule A?



Thanks.
