Maintaining sub element Costs for the Service Activity

Question

Dear Experts & MM Gurus,
Requirement is to maintain the Sub Cost Elements for the activity and to maintain different unit & Rate for the sub cost elements .
Scenario is explained below.
1. while making Purchase Requisition for Services
      in Services Tab at item level i maintained Service Activity and for that activity i had maintained sub cost elements (Such as cost estimate for the activity) like labour cost,material & consumables cost,Transportation cost with the help of Pricing MS0000.
2. My Concern is i need to maintain different unit and rate for the sub cost elements ,but system is not allowing to maintain different unit from unit available with activity unit.How can i maintain different unit for the Sub cost (pricing elements like PRSO,PRS1,PRS2) .
EXAMPLE :1. Activity is Laying of Road where unit is AU  and price will be combination of all Sub cost elements .
                  2. Sub Cost Elements like labour cost where unit is man days,system doesnt allow to maintain this unit.
pl comment /suggest on the above scenario.
Thanks in Advance ,

Hi
For services, U create activity group in AC03.
U can have upto four levels.
And Model service specifications u maintain in ML10.
Then mainatin service conditions in ML33 / ML 39 based on with or with out plant.
Then create the document, the price will pick it from the conditios u maintained.
Please check and revert back
