ABAP--如何使用'F4IF_INT_TABLE_VALUE_REQUEST'填写屏幕的多个字段

样例屏幕
 

1定义输入帮助处理

PROCESS ON VALUE-REQUEST.

 FIELD ACTIVE_SZKART MODULE YCURVE_VALUE_REQUEST.

 FIELD ACTIVE_WWAER MODULE YCURVE_VALUE_REQUEST.

 FIELD ACTIVE_DKOND MODULE YCURVE_VALUE_REQUEST.

2编写YCURVE_VALUE_REQUEST module代码

module ycurve_value_request input.

* Dieses Modul wird bei F4 auf szkart, wwaer oder dkond ausgef黨rt und

* liefert eine Liste der selektierten Zinskurven.

 data: return_tab like ddshretval occurs 1 with header line,

        field_tab like dfies occurs 1 with header line,

        dynpfields like dynpread occurs 3 with header line.

 call function 'F4IF_INT_TABLE_VALUE_REQUEST'

       exporting

            ddic_structure   = 'JBIZKARTLIST'

            retfield         = 'ACTIVE_SZKART'

            dynpprog        = 'SAPLJBYCDETAIL'

            dynpnr           = '1000'

            dynprofield      = 'X'     "Felder aufs Dynpro zur點kstellen

            window_title     = text-003

            value_org        = 'S'

            callback_program = 'SAPLJBYCDETAIL'

            callback_form    = 'BO_CALLBACK_FORM'

       tables

            value_tab        = selected_zkartlist

            field_tab        = field_tab

            return_tab       = return_tab

       exceptions

            parameter_error = 1

            no_values_found = 2

            others           = 3.

 if sy-subrc eq 0.

*   read table selected_zkartlist with key szkart = active_szkart

*                                            wwaer = active_wwaer

*                                            dkond = active_dkond.

*   move sy-tabix to active_index.

* Aktualisiere die Table Control-Daten f黵 das Tab Strip

*   perform bo_data_transfer_for_tab_strip.

 endif.

endmodule.                             " YCURVE_VALUE_REQUEST INPUT

3.编写回调函数BO_CALLBACK_FORM代码

注意红色代码块，那里定义了返回三个字段并填写到操作屏幕

form bo_callback_form

      tables   record_tab structure seahlpres

      changing shlp type shlp_descr_t

               callcontrol like ddshf4ctrl.

 data: interface like line of shlp-interface,

        fp like line of shlp-fieldprop.

 clear interface.

 clear fp.

 fp-shlpoutput = 'X'.

 modify shlp-fieldprop from fp transporting shlpoutput

          where shlpoutput = space.

 interface-shlpfield = 'SZKART'.

 interface-valfield = 'ACTIVE_SZKART'.

 append interface to shlp-interface.

 interface-shlpfield = 'WWAER'.

 interface-valfield = 'ACTIVE_WWAER'.

 append interface to shlp-interface.

 interface-shlpfield = 'DKOND'.

 interface-valfield = 'ACTIVE_DKOND'.

 append interface to shlp-interface.

 

endform.                               " BO_CALLBACK_FORM
