Having trouble in getting data from BPC to SAP

Hi,

Can anyone help me in fetching data from BPC to SAP ABAP

I can get the Dimensions into a table. But I want to get the properties of those dimensions.

I am using

TRY.

            CALL FUNCTION 'UJQ_RUN_RSDRI_QUERY'

              EXPORTING

                i_appset_id       = lv_appset_id

                i_appl_id         = lv_application_id

                it_dim_name       = lt_dim_name

                if_check_security = abap_true

                it_sel = it_sel

              IMPORTING

                et_data           = it_rate_data..

          CATCH cx_ujq_exception.

        ENDTRY.
I am not able to get any value in it_rate_data.
