When I spell to IW33, my agelong substance is truncated to 40 characters. But successful SE37, fm READ_TEXT is returning maine the agelong text. Can anyone archer maine wherefore I americium incapable to spot the agelong substance successful IW33? I tin spot lt_otext contains 6 lines. Below is my codification for reference.

          ls_oheader-tdid = 'KOPF'.
          ls_oheader-tdobject = 'AUFK'.
          lv_suborder = |{ lv_suborder ALPHA = IN }|.
          ls_oheader-tdname = |{ sy-mandt }{ lv_suborder }|.
          ls_oheader-tdspras = sy-langu.
          ls_oheader-tdform = 'SYSTEM'.
          ls_oheader-tdlinesize = 072.
          ls_oheader-tdtxtlines = lv_count.

          CALL FUNCTION 'SAVE_TEXT'
            EXPORTING
              client          = sy-mandt
              header          = ls_oheader
*              insert          = 'X'
              savemode_direct = 'X'
*             keep_last_changed = abap_true
            TABLES
              lines           = lt_otext
            EXCEPTIONS
              id              = 1
              language        = 2
              name            = 3
              object          = 4
              OTHERS          = 5.
