ABAP ALV显示前排序合并及布局显示

有时候会有用户要求显示出来的ALV立即就是升序或者降序,或者是上下同一个字段值一样的情况显示一次,如

ABAP ALV显示前排序合并及布局显示变为ABAP ALV显示前排序合并及布局显示

 

 

 这个时候内表用SORT有时候会不好用,可以使用函数

<style></style>

REUSE_ALV_GRID_DISPLAY

自带的排序属性参数---》it_sort.  布局也是需要调用相关的参数i_save。

DATA:IT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,
     WA_FIELDCAT TYPE SLIS_FIELDCAT_ALV,
     WA_LAYOUT   TYPE SLIS_LAYOUT_ALV,
     IT_SORT     TYPE SLIS_T_SORTINFO_ALV,
     WA_SORT     TYPE SLIS_SORTINFO_ALV.
SELECT * FROM EKPO INTO TABLE @DATA(IT_EKPO) UP TO 50 ROWS.
*SORT IT_EKPO BY EBELN.
*CL_DEMO_OUTPUT=>DISPLAY_DATA( IT_EKPO ).
WA_SORT-FIELDNAME = 'EBELN'.  "对需要排序的字段进行赋值
WA_SORT-UP = 'X'."up是升序,down是降序
APPEND WA_SORT TO IT_SORT.
CLEAR WA_SORT.
DATA:POS TYPE I.
POS = 1.
WA_FIELDCAT-COL_POS = POS.
WA_FIELDCAT-FIELDNAME = 'EBELN'.
WA_FIELDCAT-TABNAME = 'IT_EKPO'.
WA_FIELDCAT-SELTEXT_M = '采购订单号'.
APPEND WA_FIELDCAT TO IT_FIELDCAT.
CLEAR WA_FIELDCAT.
POS = POS + 1.
WA_FIELDCAT-COL_POS = POS.
WA_FIELDCAT-FIELDNAME = 'BUKRS'.
WA_FIELDCAT-TABNAME = 'IT_EKPO'.
WA_FIELDCAT-SELTEXT_M = '公司代码'.
APPEND WA_FIELDCAT TO IT_FIELDCAT.
CLEAR WA_FIELDCAT.
POS = POS + 1.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
  EXPORTING
    I_CALLBACK_PROGRAM = SY-REPID
    IS_LAYOUT          = WA_LAYOUT
    IT_FIELDCAT        = IT_FIELDCAT
    IT_SORT            = IT_SORT[] "这里不能忘记调用参数
    I_SAVE             = 'A'"这个是生成布局的参数
  TABLES
    T_OUTTAB           = IT_EKPO.
