Costcenter/Profit center/Internal order transaction data tables

Hi

Are there any tables other than from BSEG table for extracting transactional data of Cost center/Profit center/Internal order data .

We are in the process of extracting data for cost objects for BW reporting purpose.

I understand if we extract data from BSEG it may give performance issues.

Is there any other tables we get transactional data for cost objects other than BSEG.

regards
