CSKA & CSKB Tables -Cost Element+ Controlling Area, Cost Element Category

Question

I have few questions on Chart Of Accounts and Controlling Areas and CSKA(Cost elements (data dependent on chart of accounts)) and CSKB (Cost elements (data dependent on controlling area)) Tables--
1) One Chart Of Accounts has one or more Controlling Areas. Is there any situation where One Controlling Area contains many Chart Of Accounts.
2) CSKA Table contains all the Cost Elements under the Chart Of Accounts. So does all these Cost Elements appear under CSKB Table. Are there any Cost Elements which doesn't fall under any of the Controlling Area and only exists under Chart Of Accounts Level in CSKA Table.
3) In CSKB Table How do we know the corresponding Chart Of Accounts for the Cost Element.
4) In CSKB Table Cost Element Category depends on both Cost Element and Controlling Area. So does a Cost Element can be Primary Cost Element for one Controlling Area which happens to be GL Account and Secondary Cost Element for some controlling Areas.
5) Are there any Company Codes under the Chart Of Accounts which doesn't belong to any of the Controlling Area and doesn't have any Cost Elements.

Answer 1

Hi,
1) One Chart Of Accounts has one or more Controlling Areas. Is there any situation where One Controlling Area contains many Chart Of Accounts. Never
One controlling area can be assigned to many company codes, but all must have been assigned to the same chart of accounts only. This is the pre requisite for the so called cross company controlling
2) CSKA Table contains all the Cost Elements under the Chart Of Accounts. So does all these Cost Elements appear under CSKB Table. Are there any Cost Elements which doesn't fall under any of the Controlling Area and only exists under Chart Of Accounts Level in CSKA Table.
If some data exists in CSKA table, it mean that, it must have been created as a CE in any of the controlling area
3) In CSKB Table How do we know the corresponding Chart Of Accounts for the Cost Element.
In CSKB, you wont get the correspondant COA for the given controlling area. If you want to know it pass field value CSKB-KOKRS to table field TKA01-KTOPL to get the assigned COA
4) In CSKB Table Cost Element Category depends on both Cost Element and Controlling Area. So does a Cost Element can be Primary Cost Element for one Controlling Area which happens to be GL Account and Secondary Cost Element for some controlling Areas.
You cannot create a secondary cost elemant using a key matching with an GL code in cross company controlling. In case of both company codes assigned to different controlling areas this can be possible
5) Are there any Company Codes under the Chart Of Accounts which doesn't belong to any of the Controlling Area and doesn't have any Cost Elements.
Only In case of CO module is not active for the a company code
Note: If you have more queries, post it separately rather than asking all in one thread. and be specific with your requirement with the actual scenario.
Thanks,
