Hi Mahmud
CATS is also Integrated with CO module, where all the costings will be based on the Cost center of the employee's and controlling areas for each activity types.moreover the activity's we use in CATS will be integrated with CO where they define actual Rates for each hours used in that activity's
Ex: If a employee who belongs to quality dept and works for 2 hrs in production dept then he choose the activity type which belongs to his work done in prd dept. As they have already defined a rate for that activity types.when we transfer the data to CO module through CATS they get hours & rate. where (1hr=100rs), then in CO module the rate calculates with hours & displays the amount as 200rs.
T-codes
CAC1 - Data Entry Profile
CAC2 - Field Selections
CAT2 - Initial Data Entry screen
CAT4 - Approval times
CAT7 - Transfer data to CO
Hope this Information
will be useful
Cheers
