Try to capture the dynamic selections of a standard LDB

Question

Hi experts,
I checked on the SDN, some people said we can use set parameter and EXPORT/IMPORT to do it. Does it mean we use this statement in the LDB and send the value of selections to memory then get them in the program? If there is a standard LDB, how can I get the value of its dynamic selections?
Also There are some FMs, such as FREE_SELECT_*, but the INIT and DIALOG FM are used to show the user dialog and fetch its results. The rest FMs in the FG are used to convert the format of the selection reults. So is there any FM which can be used to get the value of the dynamic selections of a standard  LDB in my program? I hope there is a selection ID for the LDB's dynamic selection and it can be captured by a FM.
Thanks for reading and help.

use fm RS_REFRESH_FROM_DYNAMICAL_SEL
here's a sample to search for a free selection (her field XBILK)
DATA RANGE TYPE RSDS_TRANGE.
DATA : BEGIN OF WA OCCURS 0,
         TABLENAME LIKE RSDSTABS-PRIM_TAB,
         FRANGE_T TYPE RSDS_FRANGE_T,
       END OF WA.
DATA : BEGIN OF CA OCCURS 0,
         FIELDNAME LIKE RSDSTABS-PRIM_FNAME,
         SELOPT_T TYPE RSDS_SELOPT_T,
       END OF CA.
DATA ERR.
DATA: RSDSSELOPT LIKE RSDSSELOPT OCCURS   0 WITH HEADER LINE.
CALL FUNCTION 'RS_REFRESH_FROM_DYNAMICAL_SEL'
       EXPORTING
            CURR_REPORT        = SY-REPID
            MODE_WRITE_OR_MOVE = 'M'
       IMPORTING
            P_TRANGE           = RANGE
       EXCEPTIONS
            NOT_FOUND          = 1
            WRONG_TYPE         = 2
            OTHERS             = 3.
  ERR = 9.
  LOOP AT RANGE INTO WA.
    APPEND WA.
    IF WA-TABLENAME = 'SKA1'.
      ERR = 0.
    ENDIF.
  ENDLOOP.
  CHECK ERR = 0.
  ERR = 9.
  LOOP AT WA-FRANGE_T INTO CA.
    APPEND CA.
    IF CA-FIELDNAME = 'XBILK'.
      ERR = 0.
    ENDIF.
  ENDLOOP.
  CHECK ERR = 0.
  ERR = 9.
  LOOP AT CA-SELOPT_T INTO RSDSSELOPT.
    IF RSDSSELOPT = 'IEQX'.
      ERR = 0.
    ENDIF.
  ENDLOOP.
hope that helps
