Dynamic source code generation

Hi,

sorry if it's a noob question but I didn't use to develop since à long time.

I remember that there was a way to generate dynamic ABAP source code.

Fro example, generate the source code of an ABAP form depending on input parameters.

I do not remember exactly how it worked, I think that was something like that :

- you do à form that generate à string variable

- you pass the string variable + a form name too a standard function module

- the standard function module generate a form that contain the code in string variable

Please help,

Regards

Morgan

Hey Morgan,

Here's the logic for dynamic program generation

Report z_dynamic.

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).
