BADI Macro for Disaggregation in DP(APO)

Hi,

I have a planning book in APO with CVC combination Material , Program and Location.

I need to consider lowest level of history data for calculation of forecast weeks.

Hence created a BADI macro and fetching data from planning book.

Using  BAPI_PBSRVAPS_GETDETAIL2  BAPI for keyfigure data in  key_figure_value.

Also using

C_T_TAB

C_T_TAB_OLD for retrieving planning book data.

I am able to get highest level data(total value for key figures) but I need lowest level (material,program and location wise disaggregated) data.

Any suggestions on this?

Regards
