Reding values of DTP filter.

Hi,

I am trying to understand the logic for a code used to get the values entered in some fields of DTP filter.

But I am new to SAP BW, so please help to understand the logic behind the following code.

Loop at I_dtp INTO w_dtp.

r_rsbk_dtp = cl_rsbk_dtp=>factory(w_dtp-dtp).

r_rsbc_filter = cl_rsbk_dtp->if_rsbk_dtp_display~get_obj_ref_filter().

t_dtprule = r_rsbc_filter->n_t_dtprule.

Regards,

Aman Kumar Sharma
