TYPES: RSDS_SELOPT_T LIKE RSDSSELOPT OCCURS 10.
TYPES: BEGIN OF RSDS_FRANGE,
FIELDNAME LIKE RSDSTABS-PRIM_FNAME,
SELOPT_T TYPE RSDS_SELOPT_T,
END OF RSDS_FRANGE.
TYPES: RSDS_FRANGE_T TYPE RSDS_FRANGE OCCURS 10.
TYPES: BEGIN OF RSDS_RANGE,
TABLENAME LIKE RSDSTABS-PRIM_TAB,
FRANGE_T TYPE RSDS_FRANGE_T,
END OF RSDS_RANGE.
DATA: WA_RSDS_RANGE TYPE RSDS_RANGE.
CALL FUNCTION 'RS_REFRESH_FROM_DYNAMICAL_SEL'
  EXPORTING
    CURR_REPORT              = sy-cprog
    MODE_WRITE_OR_MOVE       = 'M'
