dynamic source code generation

[Former Member]

Hi guys,

I would like to declare TYPES with five fields dynamically in my program and then use the same type in program later on. For that i have written the following code.

it_code-line = 'TYPES : BEGIN OF TY_TABLE,'.

APPEND it_code. CLEAR it_code.

CONCATENATE f1 'TYPE' f1 ',' INTO it_code separated by space.

APPEND it_code. CLEAR it_code.

CONCATENATE f2 'TYPE' f2 ',' INTO it_code separated by space.

APPEND it_code. CLEAR it_code.

CONCATENATE f3 'TYPE' f3 ',' INTO it_code separated by space.

APPEND it_code. CLEAR it_code.

CONCATENATE f4 'TYPE' f4 ',' INTO it_code separated by space.

APPEND it_code. CLEAR it_code.

CONCATENATE f5 'TYPE' f5 ',' INTO it_code separated by space.

APPEND it_code. CLEAR it_code.

it_code-line = 'END OF TY_TABLE.'.

APPEND it_code. CLEAR it_code.

INSERT REPORT 'ZIBM_DYN_INCLUDE' FROM it_code.

But i am getting syntax error ' Type TY_TABLE is unknown'. How to rectify this error.

Your help will be deeply appreciated.

Thanks,

Ibrahim

Here's the sample program for Dynamic source code generation.

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).

Thanks Mahesh but i have already seen this code on SDN. It wasn't helpful so i posted my query.

why don't you use form fields for dynamic table generation ??

in https://www.sdn.sap.com/irj/scn/wiki?path=/display/abap/individualcellcoloringindynamic+alv

I have made an example where you add the fields to the fieldcat. you generate the dynamic table and line.

in this report I create fields (employeenumbers) depending on the selection on the selection screen.

so if someone selects company A on the selection screen the programm creates a table with all the employees from company a where the employeenumber is the fieldname.

further on you can also declare static fields as well to this structure.

so perhaps I misunderstood you're requirement but dynamic generation is normally done with form fields

you can also search for the method that creates the table

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = it_lvc_cat

IMPORTING

*ep_table = ta_output.*** Create a new Line with the same structure of the table.

ASSIGN ta_output->* TO <ta_output>.*

CREATE DATA new_line LIKE LINE OF <ta_output>.

ASSIGN new_line->* TO <l_line>.

kind regards
