Question

does any body tell me how to fetch data using structure with full working example
the structure name is RSTXT and the field is TXLINE
the data in the form of text is entered from the functional side using t-code ME52N
from there i have to fetch the data
in smartform or in report

Answer 1

using this code to get text from ME52N  this is a structure still not getting output  
DATA:BEGIN OF TA_ROW occurs 0,
      TXZ01(1000) TYPE C,
      END OF TA_ROW.
  DATA:BEGIN OF IT_ROW OCCURS 0,
      TXZ01(1000) TYPE C,
      END OF IT_ROW.
   DATA: thread LIKE thead.
   DATA: headerid TYPE char24.
   DATA: it_text LIKE tline OCCURS 0 WITH HEADER LINE.
   data:wa_banfn like eban-banfn.
   thread-tdid = 'B01'.
   thread-tdname = headerid.
   thread-tdobject = 'EBAN'.
     select txz01 from eban into corresponding fields of table ta_row
      where banfn = wa_banfn.
   headerid = '  '.
   CALL FUNCTION 'READ_TEXT'
     EXPORTING
  CLIENT                        = SY-MANDT
       id                            = thread-tdid
       language                      = sy-langu
       name                          = thread-tdname
       object                        = thread-tdobject
  ARCHIVE_HANDLE
                                = 0
  LOCAL_CAT                     = ' '
IMPORTING
  HEADER                        =
     TABLES
lines                         = it_text
    EXCEPTIONS
      id                            = 1
      language                      = 2
      name                          = 3
      not_found                     = 4
      object                        = 5
      reference_check               = 6
      wrong_access_to_archive       = 7
      OTHERS                        = 8.
     LOOP AT it_text.
     CLEAR ta_row.
   BREAK-POINT.
  FROM THIS POINT TEXT IS COMING
     ta_row-txz01 = it_text-tdline.
     APPEND ta_row TO it_row.
     ENDLOOP.
