Hi,

look at your previous call of method: set_table_for_first_display.

There you defined a parameter for it_outtab, which is also used in method add_node:

...

assign mt_outtab->* to <tab1>.

...

When you define it_outtab of method set_table_for_first_display and is_outtab_line of method add_node the same way, the problem should be solved.

Best regards,
