众所周知，在调用F4 help的时候，显示的字段的text是和数据库的字段相关的，那么在abap中如何修改该字段的text呢？敬请参考以下解决方法，希望对大家有所帮助。

首先要定义几个变量：

RETFIELD：这个就是数据库中的字段的名字

I_TAB： 这个是存放该帮助字段的具体值的表

I_FIELD: 这个就是存放该字段的相关信息的表

然后调用下面的form，把相关的变量传进去

PERFORM GET_FIELDS_OF_VALUE_TAB

 TABLES I_MBLNR I_FIELD

 CHANGING L_RETFIELD .

FORM GET_FIELDS_OF_VALUE_TAB TABLES VALUE_TAB FIELD_TAB STRUCTURE DFIES

                             CHANGING RETFIELD LIKE DFIES-FIELDNAME. DATA HLP(61).

  DATA OFFSET LIKE DFIES-OFFSET.

  DATA DFIES_ZWI LIKE DFIES.

  DATA DTELINFO_WA TYPE DTELINFO.

  DATA: TABNAME LIKE DD03P-TABNAME,

        LFIELDNAME LIKE DFIES-LFIELDNAME.

  FIELD-SYMBOLS: .

  DATA: I LIKE SY-INDEX.

  DATA: N(4) TYPE N.

  DESCRIBE FIELD VALUE_TAB HELP-ID HLP.

  DO.

    I = SY-INDEX.

    ASSIGN COMPONENT I OF STRUCTURE VALUE_TAB TO .

    IF SY-SUBRC <> 0 .

      EXIT.

    ENDIF.

    DESCRIBE FIELD HELP-ID HLP.

    SPLIT HLP AT '-' INTO TABNAME LFIELDNAME.

    CALL FUNCTION 'DDIF_FIELDINFO_GET'

      EXPORTING TABNAME = TABNAME

                LFIELDNAME = LFIELDNAME

                ALL_TYPES = 'X'

      IMPORTING DFIES_WA = DFIES_ZWI

      EXCEPTIONS NOT_FOUND = 1

                 INTERNAL_ERROR = 2

                 OTHERS = 3.

    CHECK SY-SUBRC = 0.

    DESCRIBE DISTANCE BETWEEN VALUE_TAB

         AND INTO DFIES_ZWI-OFFSET

          IN BYTE MODE.

    CLEAR DFIES_ZWI-TABNAME.

    DFIES_ZWI-POSITION = I.

    N = I.

    CONCATENATE 'F' N INTO DFIES_ZWI-FIELDNAME.

    DFIES_ZWI-MASK+2(1) = 'X'.

    CLEAR: DFIES_ZWI-F4AVAILABL,

           DTELINFO_WA.

    CALL FUNCTION 'DDIF_NAMETAB_GET'

      EXPORTING TABNAME = DFIES_ZWI-ROLLNAME

                ALL_TYPES = 'X'

      IMPORTING DTELINFO_WA = DTELINFO_WA

      EXCEPTIONS OTHERS = 0.

                 DFIES_ZWI-F4AVAILABL = DTELINFO_WA-F4AVAILABL.

    APPEND DFIES_ZWI TO FIELD_TAB.

  ENDDO.

  ASSIGN COMPONENT RETFIELD OF STRUCTURE VALUE_TAB TO  <F>.

  DESCRIBE DISTANCE BETWEEN VALUE_TAB AND INTO OFFSET IN BYTE MODE.

  READ TABLE FIELD_TAB WITH KEY OFFSET = OFFSET.

  CHECK SY-SUBRC = 0.

  RETFIELD = FIELD_TAB-FIELDNAME.

ENDFORM. " GET_FIELDS_OF_VALUE_TAB

然后修改得到的I_FIELD中的关于字段的text的值

  LOOP AT I_FIELD .

   I_FIELD-REPTEXT = 'xxxx' . “这个就是修改字段text的 MODIFY I_FIELD .

  ENDLOOP .

最后调用F4 help的函数，把得到的字段的值和字段的属性的表传进去

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

    EXPORTING RETFIELD = 'MBLNR'

              DYNPPROG = SY-REPID

              DYNPNR = SY-DYNNR

              DYNPROFIELD = L_FIELD

              VALUE_ORG = 'S'

              WINDOW_TITLE = 'xxxx' “帮助画面的title

    TABLES VALUE_TAB = I_TAB

           FIELD_TAB = I_FIELD

    EXCEPTIONS PARAMETER_ERROR = 1

               NO_VALUES_FOUND = 2

               OTHERS = 3.
