How to fix this error?

Before you can output forms using WRITE_FORM, you must open a form with
OPEN_FORM or START_FORM.
There are two main causes for this error:
If you attempt to use a non-existing form, OPEN_FORM or START_FORM
returns an exception (FORM). If the application does not respond to
this exception and tries to continue printing, the system terminates.
Check in Customizing if the required from is defined for printing and
whether it exists (transaction SE71, Form Painter).
The error can also occur if form printing was implicitly terminated.
This happens if a page does not have any subsequent page although
additional data is to be printed.
Check if all pages of your form have a subsequent page. In many cases,
this entry is missing. The error then occurs if other pages are to be
printed.
