Search Help Exfit for Material

Question

Hi,
Scenario:
in the F4 dropdown for material, I have added a new elementary search help which will search a laterial based on material description(makt-maktx)/basic material(mara-wrkst)/size & dimension(mara-groes).
Requirement:
I need to add one more field in my search help "Global Search". In this field whatever has been entered has to be searched in all the tree fields mentioned above. For eg.
If i enter "valve" in my global search field, then 'valve' should be searched in makt-maktx & mara-wrkst & mara-groes and should give me the total result.
Solution Lead:
I created a search help exit and inside that I found out that I have to write my code under:
IF CALLCONTROL-STEP = 'SELECT'.
Now Im not able to figure out how to write the code inside IF CALLCONTROL-STEP = 'SELECT'.
Please help.

Hi!
Say you've define input parameter PARAM for your search help. Then you should proceed as follows:
IF callcontrol-step = 'SELECT'.
    DATA:
      param_val TYPE ddshiface-value.
    CALL FUNCTION 'F4UT_PARAMETER_VALUE_GET'
      EXPORTING
        parameter               = 'PARAM'
      OFF_RESULT              = 0
      LEN_RESULT              = 0
      FIELDNAME               = ' '
     IMPORTING
       value                   = param_val
      TABLES
        shlp_tab                = shlp_tab
        record_tab              = record_tab
      SELOPT_TAB              =
      RESULTS_TAB             =
      CHANGING
        shlp                    = shlp
        callcontrol             = callcontrol
     EXCEPTIONS
       parameter_unknown       = 1
       OTHERS                  = 2
    IF sy-subrc <> 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    DATA:
      it_hitlist TYPE STANDARD TABLE OF z_your_hitlist_structure.
    IF param_val IS INITIAL.
*TODO: fill it_hitlist correspondingly
    ELSE.
*TODO: fill it_hitlist correspondingly too
    ENDIF.
    IF sy-subrc = 0.
      callcontrol-step = 'DISP'.
    ELSE.
      callcontrol-step = 'EXIT'.
    ENDIF.
    CALL FUNCTION 'F4UT_RESULTS_MAP'
    EXPORTING
      SOURCE_STRUCTURE         =
      APPLY_RESTRICTIONS       = ' '
      TABLES
        shlp_tab                 = shlp_tab
        record_tab               = record_tab
        source_tab               = it_hitlist
      CHANGING
        shlp                     = shlp
        callcontrol              = callcontrol
     EXCEPTIONS
       illegal_structure        = 1
       OTHERS                   = 2
    IF sy-subrc <> 0.
      MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
        WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.
ENDIF.
