搜索帮助——选择屏幕SCREEN

前言:有时候SAP系统报表程序的选择屏幕条件是没有F4帮助的，这时候就需要通过函数自定义实现，通过函数F4IF_INT_TABLE_VALUE_REQUEST可以实现这一需求。

案例：给选择条件物料特性值包装规格添加搜索帮助

步骤如下代码所示：

DATA:gv_zbzgg    TYPE ausp-atinn.
 
*--------------------------------------------------------------------*
*&--------------------------「PROCESS」-----------------------------&*
*--------------------------------------------------------------------*
INITIALIZATION.    "获取ZBGGG的内部特性值
  PERFORM frm_atinn_trans USING 'ZBZGG' CHANGING gv_zbzgg     .
    
AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_zbzgg-low.
  PERFORM frm_get_atwrt USING gv_zbzgg.    "调用自定义搜索帮助
    
    
*&---------------------------------------------------------------------*
*& Form frm_atinn_trans
*&---------------------------------------------------------------------*
*& 特性值转换
*&---------------------------------------------------------------------*
FORM frm_atinn_trans  USING p_atinn_i CHANGING p_atinn_o.
  CALL FUNCTION 'CONVERSION_EXIT_ATINN_INPUT'
    EXPORTING
      input  = p_atinn_i
    IMPORTING
      output = p_atinn_o.
ENDFORM.
    
*&---------------------------------------------------------------------*
*& Form frm_get_atwrt
*&---------------------------------------------------------------------*
*& 获取cawn特性值
*&---------------------------------------------------------------------*
FORM frm_get_atwrt USING p_atinn.
  SELECT atwrt INTO TABLE @DATA(lt_cawn) FROM cawn WHERE atinn = @p_atinn.  "获取数据
  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'    "实现搜索帮助"
    EXPORTING
      retfield        = 'ATWRT'     "值-关联指端
      dynpprog        = sy-repid
      dynpnr          = sy-dynnr
      dynprofield     = 'S_ZYYYHG'     "关联的屏幕字段
      value_org       = 'S'            "屏幕字段类型
    TABLES
      value_tab       = lt_cawn        "值表
    EXCEPTIONS
      parameter_error = 1
      no_values_found = 2
      OTHERS          = 3.
ENDFORM.

效果如下图：
