Unable to use RSDRI_INFOPROV_READ in IF_UJD_ROUTINE

hi Guys,

During end_routine ( BW data loading to BPC model)  in  BADI_UJD_ROUTINE, i am able to read data from a model using  RUN_RSDRI_QUERY provided i clear the staging cube  ZCOOM_C08 that is currently running using the below code:

CALL FUNCTION 'RSDRI_INFOPROV_READ'

     EXPORTING

       i_infoprov           = 'DUMMY'

       i_th_sfc             = i_th_sfc

       i_th_sfk             = lt_sfk

*     i_t_range            = g_t_range

*     i_packagesize        = 10000

*     i_use_db_aggregation = ' '

       i_clear              = rs_c_true

     IMPORTING

       e_t_data             = <lt_eq> "lt_cube

     CHANGING

       c_first_call         = lv_first_call.

this way, i am successfully able to read data from a model but this  has caused endless loop in the entire logic IF_UJD_ROUTINE~RUNROUTINE and not able to complete this BW loading , how can i read a data from a model during BW loading at the same time not causing endless loop ?
