WORKING TO SPLIT THE VARIABLE AND FIXED EXPENSES FOR MATERIAL ZTFG
1) Go to the following patch
Path: Information system>general report selection
Application tree report selection general>report selection>controlling>customized reports>cost center reports
2) From the above ZSL2 / ZSL 3 report, in order to get the mapping of the allocation to material, go to Cost Center Report (program J1SIPAAX).
EXAMPLE :-
The following is the sample file extracted from Cost Center Actual Line Item Report for period 1 fiscal year 2007:-
From the above sample file, material 4900154401 (ZTFG) received 16.80 (0.2%) out of total 8,526.56. Hence, the following sender cost elements will be split  as below:-
5014700 => 296.87 x 0.2% = 0.59
5014800 => 157.49 x 0.2% = 0.32
5015202 => 314.29 x 0.2% = 0.63
and so on
According to the mapping logic in page 6, since 5014700 and 5014800 is categorised as Depreciation = Fixed Expenses, the sum received will be 0.91 (0.59 + 0.32). Whereas, for 5015202, it will be categorised as Sundry Tools = Variable Expenses in the new customised report.
