有表 STXH (用于标题)和 STXL (用于行)，但是它们不可读开箱即用.
通常通过READ_TEXT FM来阅读文本:

There are tables STXH (for header) and STXL (for lines) but they are not readable out-of-the-box.
Usually reading texts is made by READ_TEXT FM:

CALL FUNCTION 'READ_TEXT'
 EXPORTING
  client = sy-mandt
  id = 'F01'
  language = 'E'
  name = %PO_number% + %PO_pos%
  object = 'EKPO'

要找出必要文本的ID/名称，应进入编辑模式，然后按转到>>标头，其中应检查对应字段

To find out ID/name of necessary text one should enter edit mode and press Goto >> Header where one should check correspondent fields

更新:根据上述示例大量提取文本

UPDATE: mass extraction of texts based on the above example
