Hi Parag,
Controlling has to create the required fixed cost centers and cost types.
(Has to create G/L accounts in Financial Accounting (FI) for the primary cost elements.
Then you have to enter this dates in 'Set up Postings for Fixed Costs'.
The wage type has to be assigned to the symbolic account which is assigned to the Primary cost element/GL account.
During the posting process the system refers to the entry of 'Set up Postings for Fixed Costs' and posts the wage type to the according fix Cost Center and not the the Cost Center of the employee.
Please check attached short Doku.
Hope this helps!
