当选择屏幕上的一个字段所参考的数据元素没有建立搜索帮助时，可以手工建立一个：
　　1、在se11创建一个搜索帮助ZAUTEST，需要输入：
　　（1）描述；
　　（2）选择方法：即搜索帮助显示字段所在的透明表；
　　（3）搜索帮助参数：即搜索帮助要显示的字段；
　　（4）IMP：输入字段，勾上即表示显示该字段；
　　（5）EXP：输出字段，勾上即表示该字段是搜索帮助需要的输入字段；
（6）Lpos：搜索帮助下半部分字段排序；Spos：搜索帮助上半部分字段排序。
　　如下图：

在Dialog屏幕中给输入字段建立搜索帮助，有以下三种情况：
一：直接使用系统已有的搜索帮助，对于系统已存在搜索帮助的输入字段可直接使用：在屏幕格式器里双击输入字段框，在其“属性”栏的“搜索帮助”框内填入该字段的搜索帮助名称。如物料“matnr”的搜索帮助名称为“MAT1”。注意：MAT1一定要大写，对于所有在屏幕输入的字符，不管以任何形式输入都要大写，否则系统是不认识的，就如在代码里引号内的字符串要大写才正确一样。

二：自建搜索帮助，其过程如下：
1、在dialog屏幕的逻辑流里在user_command后定义module，如下：
process before output.
...
process after input.
module user_command_0100.
process on value-request. "输入字段的响应
field t_pline module f4_help_for_pline. "“t_plnnr”是输入字段的“name”，“f4_help_for_pline”是module名，自己随便起吧
2、双击“f4_help_for_pline”创建该module，这时进入程序代码编辑，module如下：
module f4_help_for_pline input.
  call function 'F4IF_INT_TABLE_VALUE_REQUEST' "调用函数
    exporting
      retfield    = 'PLINE'  "搜索帮助内表要输出的的帮助字段名，注：要大写
      dynpprog    = sy-repid
      dynpnr      = sy-dynnr
*      dynprofield = ''
      value_org   = 'S'
    tables
      value_tab   = ithp_pline. "存储搜索帮助内容的内表
endmodule.                 " f4_help_for_pline  INPUT
注：“retfield”的内表输出字段的名字要和输入字段保持一致，并最好和透明表的字段名一致，否则弹出的搜索帮助会显示不了字段名。
3、在屏幕输出前或在上一屏幕进入本屏幕的动作发生后，取得搜索帮助的内容，如下：
    clear ithp_pline[].
    select pline pltxt
     into corresponding fields of table ithp_pline
     from afpo
     where dwerk = t_werks
     and matnr = t_matnr.
内表ithp_pline有两个字段pline、pltxt即是搜索帮助将显示的两个列，其中ithp_pline是输入字段。

三：联动搜索帮助的建立：有两个输入字段要建立搜索帮助，并且这两个字段是相互关联的，选择一个字段的输入值同时也选择了另一个字段的值，比如顺序与工序的关系必需是相互的。
1、定义
data:field_tab_vgn type dfies occurs 0,
     dynpfld_mapping_vgn type dselc occurs 0,
     wa_map_vgn type dselc,
     field_tab_pln type dfies occurs 0,
     dynpfld_mapping_pln type dselc occurs 0,
     wa_map_pln type dselc.
2、在dialog屏幕的逻辑流里在user_command后定义module，如下：
process before output.
...
process after input.
module user_command_0100.
process on value-request.
field:it_bg-plnfl module f4_help_for_vornr, "顺序、工序的联动搜索
      it_bg-vornr module f4_help_for_vornr.
3、双击“f4_help_for_vornr”创建该module，这时进入程序代码编辑，module如下：
module f4_help_for_vornr input.
  call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
      retfield    = 'PLNFL'  "搜索帮助要输出的的帮助字段名
      dynpprog    = sy-repid
      dynpnr      = sy-dynnr
      dynprofield = 'T_PLNFL'   "“T_PLNFL”为输入字段，在此用T_VORNR也可以但上面的retfield名也要改
      value_org   = 'S'
    tables
      field_tab   = field_tab_vgn  "联动关系表
      dynpfld_mapping = dynpfld_mapping_vgn "存储联动内容的内表
      value_tab   = ithp_vgn. "存储搜索帮助的内表
endmodule.                 " f4_help_for_vornr  INPUT
4、在屏幕输出前或在上一屏幕进入本屏幕的动作发生后，取得搜索帮助的内容，如下：
   clear ithp_vgn[].
   select plnfl vornr ltxa1
    into corresponding fields of table ithp_vgn
    from afko
    inner join afvc on afvc~aufpl = afko~aufpl
    where afko~aufnr = t_aufnr.
  "调用联动函数
  call function 'ZSET_F4_FIELD_FROM_VALUE_TAB'
    tables
      value_tab = ithp_vgn       "存储搜索帮助的内表
      field_tab = field_tab_vgn. "联动关系表
  clear dynpfld_mapping_vgn[].
  wa_map_vgn-fldname = 'PLNFL'.  "帮助内表字段
  wa_map_vgn-dyfldname = 'T_PLNFL'. "输入字段
  append wa_map_vgn to dynpfld_mapping_vgn.
  wa_map_vgn-fldname = 'VORNR'.
  wa_map_vgn-dyfldname = 'T_VORNR'.
  append wa_map_vgn to dynpfld_mapping_vgn.
