本來程式這樣寫～在OPEN_FORM後才接著定義SCRIPT要用的ITAB或相關變數

call function 'OPEN_FORM'
     exporting
          form               = 'ZSCRIPT01'
          language           = sy-langu
          device             = 'PRINTER'
     exceptions
          canceled                    = 1
          device                      = 2


DATA: z900 LIKE sp_konv OCCURS 0 WITH HEADER LINE.


*================================================
            LOOP AT Z900.
                  CALL FUNCTION 'WRITE_FORM'
                    EXPORTING
                      WINDOW = 'MAIN'
                      element = 'ITEM_LINE_Z900'.
             ENDLOOP.
*====================================================

結果報表怎輸出那個ITAB或變數都是空白的....................
後來測的半天
我把
DATA: z900 LIKE sp_konv OCCURS 0 WITH HEADER LINE.
往前移到
call function 'OPEN_FORM'
之前

就能正常輸出資料的
