Hello JK S,
This can be known through CM01. Run this for your WorkCenter and Planner Group of Technical Objects to know the Workload. And then run for Planner Group of Other jobs. Thus both the loads are known.
If PlGroup option is not suitable to you, then Run this with only WorkCenter value and in the output you can know the details through Cap. details/period button.
Note that out put is available with week number of the year.(Presently we are in 43rd week of the year)
