一、工作区Work Area
代码语言：javascript复制DATA: gt_out TYPE STANDARD TABLE OF zssd005_out_1,
gs_out TYPE zssd005_out_1.
**********************************************
*OLD SYNTAX:先定义工作区ls_export
DATA: ls_export TYPE zssd005_out_2.
LOOP AT gt_out INTO gs_out.
MOVE-CORRESPONDING gs_out TO ls_export.
ENDLOOP.
**********************************************
*NEW SYNTAX:不需要预先定义工作区ls_export
LOOP AT gt_out INTO gs_out.
DATA(ls_export) = CORRESPONDING zssd005_out_2( gs_out ).
ENDLOOP.工作区（mapping&except）
代码语言：javascript复制REPORT ztest.

代码语言：javascript复制REPORT ZTEST.
DATA: LT_T001 TYPE STANDARD TABLE OF ACDOCA.
SELECT

UP TO 3 ROWS
INTO TABLE @DATA(LT_BSEG).
"CORRESPONDING
LT_T001 = CORRESPONDING #( LT_BSEG MAPPING RBUKRS = BUKRS

"Display data
CL_SALV_TABLE=>FACTORY(
IMPORTING
R_SALV_TABLE = DATA(LCL_ALV)
