Is there a way to bypass activity type/ cost element for CJ20n Activity?

Hi Experts,

Is there a way to bypass the activity type set in the Internal tab of a particular activity in CJ20n?

Here's a background of the scenario:.

- In CJ20n, under WBS element 100->Network 10->Activity 1, under the internal tab, the activity type set up is ACT1

- Under person assignment, I have 2 resources assigned Person 1 and Person 2, with the following values:

  Person 1          Work: 1.0h Dur. 10D

  Person 2          Work: 2.0h Dur. 15D

- In infotype 135, person 1 has a cost element set as ACT2 and person 2 has a cost element ACT3.

- The problem is that when you bring up the Plan/ Actual comparision report (ctrl+F11 in CJ20n), the costs are consolidated for ACT1 and negates the cost elements for Person 1 and Person 2

Is there a way to bypass this and use the individual cost elements set up for person 1 and person 2?
