# actual number of employees in confirmation not update the cost

As the requirement costing need to calculate the costing for the labors that drive the work center

They want to add the activity type price by labor

The case is the work center has 3 labors and in some time could be 2 labors

According to that I made the below formula in work center costing tab

(SAP_02 * SAP_09 * SAP_17 / SAP_08 )

And assigned it to the work center as below

Activity rate for machine 7 EGB & for labor 5 EGB

So formula calculate right as the formula testÂ

100 Pc per hour and operation will be 200 so need 2 hours from

In routing I said there are 3 employees and 100 for 1 hour for machine and labor

In production order by 500 PC found the formula calculating right

In confirmation I made for 300 PC with 3 labors as below

- The question is why when I change the number of labors in confirmation the number of hour not updated?
- And the actual cost calculated for the number of hours not for the number of labor
- Should I update the number of labors and calculate the need hours out of system to update the confirmation?
