Hi Experts,

i need to develop a program which has selection screen to take the input from user like target program name, fields and tables from which the data comes, data selection conditions etc. . On dat basis it will create a new alv program code. Do u guys have any idea?

Thanks.

Hi,

Could you please be more specific , do you want to display the code on the alv or create a new program based on the selection

Its pretty simple we can easily do this in both the cases

This very much sounds like building a query via transaction SQVI, right? Better to use that instead of re-inventing the wheel....

Whenever there is a need to generate reports without doing any ABAP coding in a quick span of time, go for ABAP Queries.

The transaction codes associated with ABAP Query are

SQ01 - ABAP Query

SQ02 - Infoset

SQ03 - User group

Or use report painter

Tcode FGRP - It shows a sap menu structure only for report painter/writer.

Hi,

If your requirement is creating a report from within a report then its quite easy:

REPORT  ZRAJ_DYNAMIC.

DATA: code TYPE TABLE OF rssource-line.

APPEND  'REPORT ZRAJ_DYN1.'
   TO code.

APPEND  'WRITE / ''This is a dynamically created report...''.'
   TO code.

.............................
(you may append watever code you need to append this way)
.............................

INSERT REPORT 'ZRAJ_DYN1' FROM code.

Hope this helps..

Regards.

If you are looking for dynamic source code generation within the program.

Here's sample code

data: begin of itab occurs 0,
        line(150),
        end of itab.

data: v_name like sy-repid.

parameters: p_table like dd02l-tabname.

itab-line = 'Report sy-repid.'.
append itab. clear itab.
itab-line = 'tables:'.
append itab. clear itab.
concatenate p_table '.' into itab.
itab-line = 'data: begin of itab occurs 0.'.
append itab. clear itab.
concatenate 'include structure' p_table '.' into itab separated by space.
itab-line = 'data:end of itab.'.
append itab. clear itab.
itab-line = 'form f_select.'.
append itab. clear itab.
itab-line = 'select * into table itab'.
append itab. clear itab.
concatenate 'FROM' p_table '.' INTO itab separated by space.
itab-line = 'endform.'.
append itab. clear itab.


generate subroutine pool itab name v_name.
perform f_select in program (v_name).

I dont need to generate the code in same program...i need it to make a new program from my existing program..In my existing prog selection screen, it takes the names of required tables and fields which are used in target prog . .this target prog is totally diffrent from existing prog.

Use INSERT REPORT <Target Program Name> FROM <internal table> PROGRAM TYPE <pid>

pid indicates whethe the program is Executable program , Function group or function pool , Include program ,M Module pool,Subroutine pool . Try this one

Thanks
