ABAP S4HANA 7.4 新语法总结

1.READ

SELECT * FROM ekkn INTO TABLE @DATA(lt_ekkn) UP TO 100 ROWS. DATA lv_aufnr TYPE ekkn-aufnr. READ TABLE lt_ekkn INTO DATA(ls_ekkn) WITH KEY aufnr = lv_aufnr. IF sy-subrc = 0. ENDIF. * 新语法 " 其中 OPTIONAL 是防止 lv_aufnr 读不到值抛异常 DATA(ls_ekkn) = VALUE #( lt_ekkn[ aufnr = lv_aufnr ] OPTIONAL ).

2.VALUE 添加行

* 添加单条 APPEND VALUE #( matnr = ls_ekkn-matnr aufnr = ls_ekkn-aufnr ) TO lt_alv. * 添加多条 RANGES r_aufnr FOR ekkn-aufnr. r_aufnr = VALUE #( ( sign = 'I' option = 'EQ' low = '210001245641') ( sign = 'I' option = 'EQ' low = '210001245642') ).

3. FOR 循环 替代 LOOP 循环

* FOR 循环汇总 DATA(lv_menge_sum) = REDUCE menge_d( INIT sum = 0 FOR ls_ekkn IN lt_ekkn NEXT sum = sum + ls_ekkn-menge ). * 将 A表 数据 按条件 导进B表 SELECT * FROM ekkn INTO TABLE @DATA(lt_ekkn) UP TO 100 ROWS. TYPES:BEGIN OF ty_ebeln, ebeln TYPE ekkn-ebeln, sakto TYPE ekkn-sakto, END OF ty_ebeln. DATA lt_ebeln TYPE TABLE OF ty_ebeln. lt_ebeln = VALUE #( FOR ls_ekkn IN lt_ekkn WHERE ( sakto = '210001245642' ) ( ebeln = ls_ekkn-ebeln sakto = ls_ekkn-sakto ) ).

4.字符串拼接

" 字符串拼接 去前导零 DATA(lv_vbeln) = '0000012345'. WRITE: | 销售订单号：{ lv_vbeln ALPHA = OUT } 已发货 |. " 字符串拼接 补前导零 lv_vbeln = '12345'. WRITE: | 销售订单号：{ lv_vbeln ALPHA = IN } 已发货 |. " 大小写 转换 WRITE: |{ 'Abc' CASE = UPPER }|. WRITE: |{ 'Abc' CASE = LOWER }|. " 对齐 长度 填充 WRITE: |{ 'Left' WIDTH = 30 ALIGN = LEFT PAD = '0' }|. " 左对齐 用 0 填充右侧 WRITE: |{ 'Right' WIDTH = 20 ALIGN = RIGHT PAD = '0' }|. " 右对齐 用 0 填充左侧 WRITE: |{ 'Mid' WIDTH = 20 ALIGN = CENTER PAD = '0' }|. " 居中对齐 用 0 填充左右两侧 " 日期时间转换 WRITE: / |{ sy-datum DATE = ISO }|. " 2026-09-09 WRITE: / |{ sy-datum DATE = USER }|. " 按用户主数据格式，如 09.09.2026 WRITE: / |{ sy-uzeit TIME = ISO }|. " 13:40:58
