Baseline Cumulative Work and Cumulative Actual Work not avaialble

[SSayan]

Hello everyone,

I'm using MS project for my schedule and I'm usually having a pretty standard and simple usage of it I just use the duration and links between task.

However, I decided to go to the next level and get my As built and my project S-Curve.
I found a large number of tutorial on how to do that, however I get stuck when I'm asked to add the following columns to the report:
- Baseline Cumulative Work
- Cumulative Actual Work

I can't find them in the list.
My Actual Work and Baseline Work are available but not the cumulative. I can't find any explanation why.

Could anyone help me with that?

Thanks
