Ever wonder where to hard code your text ? I mean not within your program but in another place where you can call them? useful for pdf/email and etc
Recently found out from my colleague that we could use transaction

so10 (standard text) where we could create the text and import them using function call

  "Retrieve email template in ITF format
  CALL FUNCTION 'READ_TEXT'
    EXPORTING
      ID                      = 'ST'
      LANGUAGE                = SY-LANGU
      NAME                    = I_TEMPLATE_NAME
      OBJECT                  = 'TEXT'
    IMPORTING
      HEADER                  = LS_HEADER
    TABLES
      LINES                   = LT_EMAIL_TEMPLATE_RAW
    EXCEPTIONS
      ID                      = 1
      LANGUAGE                = 2
      NAME                    = 3
      NOT_FOUND               = 4
      OBJECT                  = 5
      REFERENCE_CHECK         = 6
      WRONG_ACCESS_TO_ARCHIVE = 7
      OTHERS                  = 8.
  IF SY-SUBRC <> 0.
    EXIT. "No email to be sent
  ENDIF.
