Hi Kashif
Planned and Baseline is same, you might be trying to compare %progress timewise planned/baseline vs actual
you can do one thing,
1) Define a resource nonlabor type (i.e. Dur ) keep price/unit as 0 and default unit/time and max unit/time as 1
so for any activity budgeted units is same as duration (i.e. 1* duration = duration).
2) Select all activity by pressing Ctrl+A (highlight all) Resource from the menu.
3) Select the new created resource (i.e. Dur ) and double click. (These will assign resource to all highlighted activities)
4) now go to reports Activity Resource and Role Assignments , see monthly/weekly and cummulative budgeted units for this resource (Dur), now u can plot these weekly/monthly values in excel to get the S-curve for planned duration complete.
5) once u update the schedule same way u can get the actual budgeted units for resource (Dur), and plot this against the planned curve.
this is just to compare duration complete planned vs actual
