Write_form_lines not printing the internal table

[Former Member]

Hi,

I'm using write_form_lines to print an internal table in a normal window.This is the code I'm using. The t_header table does not contain any records and there are 10 lines in the itab.But its not printing anything.

CALL FUNCTION 'WRITE_FORM_LINES'

EXPORTING

function = 'APPEND'

header = t_header

window = 'FIRST'

TABLES

lines = itab.

Thanks

Hello Nidhi,

In the query you have written that t_header is a table, I hope its a workarea not table. I mean header should be a workarea of type (Line of itab).

Data: t_header like line of itab.

I hope its the same. May be you can allow the execption of the function module and see if any aception is raised by checking the value of sy-subrc.

Hi Sesh,

Its a work area only. This is actually on the second page and it does not have a main window. Would that make any difference?

The sy-subrc returned by the function is zero.

Hi try this code.

Its working perfectly.

Replace the form name with yours and also window used.

try to use main window just for testing.

REPORT ZWA_TEST2 .

Data: t_header type thead .

DATA: itab like tline occurs 0 with header line.

itab-tdformat = '01'.

itab-tdline = 'HEllo this is first line'.

append itab.

itab-tdformat = '02'.

itab-tdline = 'HEllo this is second line'.

append itab.

CALL FUNCTION 'OPEN_FORM'

EXPORTING

FORM = 'ZWA_FD_PERMANENT'.

CALL FUNCTION 'WRITE_FORM_LINES'

EXPORTING

function = 'APPEND'

header = t_header

window = 'MAIN'

TABLES

lines = itab.

CALL FUNCTION 'CLOSE_FORM' .

Hi,

The problem was that the page did not have a main window.So now I've put a main window for the page and that sorted out the problem.

Thanks
