Hello Sunil

The class is basically a list writer. Have a look at my sample report ZUS_SDN_CL_DOPR_WRITER. Just play around with the class methods to understand their functionality.

*&---------------------------------------------------------------------*

  NO STANDARD PAGE HEADING.

  go_writer    TYPE REF TO cl_dopr_writer,
  gd_title_1 TYPE string,
  gd_title_part1 TYPE string,
  gd_title_part2 TYPE string,

  gd_hlp_txt1 TYPE c LENGTH 15,
  gd_hlp_string TYPE string,

  gd_hlp_i TYPE i.


START-OF-SELECTION.

  CREATE OBJECT go_writer.

  CONCATENATE syst-datum syst-uzeit syst-uname

  CALL METHOD go_writer->new_table

  go_writer->ruler_write( ).

  gd_title_1 = 'New title - table of type = 1'.

  CALL METHOD go_writer->new_table

      id_title = gd_title_1

  go_writer->add_header_field( text-560 ).

  RESERVE 10 LINES.
  go_writer->title_write( ).
  go_writer->ruler_write( ).

END-OF-SELECTION.

Hi Uwe Schieferstein ,

Thanx a lot for ur useful answer. I still i have some dbts plesae could you clear that.

1.Is there any documentation reagarding the Cl_dopr_writer so that i learn hw each method works.

2.When we are giveing header fields in first colum it is taking 3-4 variables in first column and after that a new column is generationg ? y so? i mean in first column it is taking some 3 to 4 varibles names and after that a new column is generating.

3.Can u give me a example such as taking a database table getting the values in internal table and getting output list using Cl_dopr_writer.? i have understood how to give the header name but i dont know how to assaing values in that. Please help me out coz atleast if i get the documentation reading all the methos how they use also i can try my self i have a requriremnt in which they used cl_dopr_writer so i cant understand anything my requirent is to insert a new field in between already existing fields.

Thanks a lot it was very useful answer to me....

use of CL_DOPR_WRITER

class CL_DOPR_WRITER (variable LO_WRITER in the report). You have to do some debugging of the report in order to understand how its methods work.

Hello Sunil

My sample report is based on the coding of the two reports which use class CL_DOPR_WRITER. Do some debugging of these rather simple reports in order to understand how to create an entire list. It is not that difficult.

Regards

Uwe
