SAP中所有的长文本都存在如下两张表中：

STXH 长文本的抬头信息
STXL 长文本的明细信息

长文本在使用前，需要先进行配置，如果不配置是不可能往表STXH和STXL中写入文本值的。

配置在视图V_TTXIDI和视图V_TTXOBI中进行。

前台事务代码：SE75

保存之后，双击“ZSD001”进入维护ID。

相应的对长文本进行增加、保存、删除的ABAP代码示例如下：把

变量的声明

DATA: lines TYPE STANDARD TABLE OF tline ,
      it_line TYPE TABLE OF line,
      header LIKE thead .
DATA: container1 TYPE REF TO cl_gui_custom_container,
      editor1    TYPE REF TO cl_gui_textedit.
DATA: ok_code LIKE sy-ucomm,
      save_ok LIKE sy-ucomm.

长文本的初始化

  IF container1 IS INITIAL.
    CREATE OBJECT:container1 EXPORTING container_name = 'COMMENT1',
                  editor1    EXPORTING parent = container1.
  CALL METHOD editor1->set_statusbar_mode
    EXPORTING
      statusbar_mode = 0.
 
  CALL METHOD editor1->set_toolbar_mode
    EXPORTING
      toolbar_mode = 0.
ENDIF.
  CALL METHOD editor1->set_text_as_stream
    EXPORTING
      text = it_line.

长文本的保存

 REFRESH it_line.
  CALL METHOD editor1->get_text_as_stream
    IMPORTING
      text = it_line.
*--长文本保存
    header-tdobject  = 'Z_TEST01'.     "object
    header-tdname    = '001'.
    header-tdid      = 'LTXT'.
    header-tdspras   = sy-langu.
    CALL FUNCTION 'CONVERT_STREAM_TO_ITF_TEXT'
      EXPORTING
        language    = sy-langu
      TABLES
        text_stream = it_line
        itf_text    = lines.
    CALL FUNCTION 'SAVE_TEXT'
      EXPORTING
        header          = header
        savemode_direct = 'X'
      TABLES
        lines           = lines
      EXCEPTIONS
        id              = 1
        language        = 2
        name            = 3
        object          = 4
        OTHERS          = 5.
    CLEAR header.
    REFRESH lines.

长文本的显示

   header-tdobject  = 'Z_TEST01'.     "object
   header-tdname    = '001'.
   header-tdid      = 'LTXT'.
   header-tdspras   = sy-langu.
   CALL FUNCTION 'READ_TEXT'
     EXPORTING
       id                      = header-tdid
       language                = sy-langu
       name                    = header-tdname
       object                  = header-tdobject
     TABLES
       lines                   = lines
     EXCEPTIONS
       id                      = 1
       language                = 2
       name                    = 3
       not_found               = 4
       object                  = 5
       reference_check         = 6
       wrong_access_to_archive = 7
       OTHERS                  = 8.
   CALL FUNCTION 'CONVERT_ITF_TO_STREAM_TEXT'
     EXPORTING
       language    = sy-langu
     TABLES
       itf_text    = lines
       text_stream = it_line.
   CALL METHOD editor1->set_statusbar_mode
     EXPORTING
       statusbar_mode = 0.
   CALL METHOD editor1->set_toolbar_mode
     EXPORTING
       toolbar_mode = 0.
   CALL METHOD editor1->set_text_as_stream
     EXPORTING
       text = it_line.
   CALL METHOD editor1->set_readonly_mode
     EXPORTING
       readonly_mode = '1'.

长文本的删除

header-tdobject  = 'Z_TEST01'.     "object
   header-tdname    = '001'.
   header-tdid      = 'LTXT'.
   header-tdspras   = sy-langu.
  CALL FUNCTION 'DELETE_TEXT'
   EXPORTING
       id                      = header-tdid
       language                = sy-langu
       name                    = header-tdname
       object                  = header-tdobject
*     SAVEMODE_DIRECT       = ' '
*     TEXTMEMORY_ONLY       = ' '
*     LOCAL_CAT             = ' '
*   EXCEPTIONS
*     NOT_FOUND             = 1
*     OTHERS                = 2
          .
  IF sy-subrc <> 0.
   MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
           WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

在ABAP的长文本操作中，我们是无法直接看到存储的长文本的，只能通过程序读取长文本在界面中显示，这点是和其他类型的变量区别开来的。
