how to manipulate table c_t_data in IF_EX_RSROA_OLAP_BADI~COMPUTE_TABLE

Dear all,

I'm implementing virtual KF into my BEx query. I'm using new kernel based BADI RSROA_OLAP_BADI concept.

The logic that I need to implement requires to delete/add entries of table C_T_DATA (retrieved by BW Data Manager) as per condition.

The condition is that I need to delete entries older than date field from BEx query's variable from selection screen.

I'd like to process whole table C_T_DATA at once so I placed my code to method COMPUTE_TABLE.

However I have a troubles to LOOP table C_T_DATA. As table is of generic type ANY I think I need to describe the table structure by RTTS (Run Time Type Service) in order to manipulate it...

Can someone provide example code of how to treat the table C_T_DATA in COMPUTE_TABLE method of RSROA_OLAP_BADI BADI?

Thanks in advance
