Work Field In Resource Sheet

Question

The Work field in the Resource Sheet is calculated total hours for each resource based on the Duration in the Gantt chart. However, I have another field in the Gantt chart named Duration1 and I want Work field in the Resource Sheet to be calculated based
on Duration1 not Duration. What formula can I use to customize Work field in Resource Sheet?

Answer 1

Thanks guys! Since, there is no way to keep Duration different from the Actual Duration, I baselined Duration. Now, similarly, I would also like to baseline Work; however, baselined Work doesn't reflect
input values of Work field. Also, just how Duration and Work data are different in my plan, Actual Duration and Actual Work may also differ. I was able to keep the Work values different from the Duration by changing the Duration task type.
Is there a way to fix Actual Duration as well so that it's not same as Actual Work?
Duration = allocated duration to complete the task [Task Type: Fixed Duration]
Work = time it should take to complete the task [Different from Duration]
Actual Duration = taken duration to complete the task
Actual Work = time it took to complete the task
Also, in Resource Sheet, is there a way to compare Baseline Work with Actual Work for
each resource as well as Baseline Cost based on Baseline Work with Actual Cost based on Actual Work?
This would allow us to work in the same plan while comparing the plan (by Start/Finish, Work in Gantt, Work in Resource Sheet, and Cost) before and after implementation. If not, then I guess we can have two copies of the plan (one for before implementation
and the other for after) with Duration and Work where task type is fixed Duration.
A few comment: 
baselined Work doesn't reflect input values of Work field : when you
save a baseline, the behavior is the same for all data copied in the baseline fields. The current value is stored is the corresponding baseline field. Ie when saving baseline n, work is copied in the baselinework n and duration is copied in the baselineduration
n.
Actual Work = time it took to complete the task
: actual work is the effort and not the time it took to complete the task
is there a way to compare Baseline Work with Actual Work for each resource :  if you split your screen and display the task form with work
information, you'll see for each assignment work, actual work, baseline work, remaining work. Another way, if you need it timephased, is to use the resource or task usage views and add the baseline, actual and planned work (double clicking the right part of
your screen).
Hope this helps.
