PP - View Production Order Cost Balance

I need help regarding the following situation. I need to see the Legal Valuation in Cost Balance for some Production Orders (Collective View). The Information I need can be obtained for a single PO by entering the PO (transaction CO03) -> GoTo-> Costs-> Balance-> an I find the Information in Balance in controlling area currency in Legal valuation.

The Information I need is the field WKG_0 in the Structure KPARALLEL_VAL. Can someone please tell me in which Database table I can find this information?

The information is also to be found in the field ISTKOST_G of the structure KKBCS_OUT.

So if you think you can help me please send a e-mail at calinmri@schaeffler.com.

Thanks.
