Dear Experts
I have a question on the activity types defined for capturing the cost of internal activities. I want to know how to define (in concept and not in system) activity types. Let examine a case:
there are 6 work centers in which different personnel work in each of them. the range of the salary for the personnel in each work center is wide e.g. from 10$/hr to 50$/hr. The personnel are not fixed for specific projects and a person may work on several projects.
I define e.g. 5 activity types in a work center with rates of 14$/hr, 22$/hr, 30$/hr, 38$/hr, and 46$/hr, and I assign the activity type with the rate of 14$/hr to activity A but a person works on this activity with real salary rate of 50$/hr. In such a case, the actual cost of the personnel assigned to a activity differs significantly from the rate of the activity type assigned to that activity and hence the calculated costs of project are not true.
What should I do in such a case and what in the solution?
What are the differentiation measures for defining activity types to capture this difference between the salary rates of personnel?
Please give some suggestions and helps for this issue.
Thanks in advance
