I want to update SPIT_VBRK table for print character and cert ID.

I have been trying to find a way to populate the table for some biling documents. the output is in error and hence won't print. Issue is that the SPIT_VBRK table doesn't have print character for these billing documents.

Is there a program and specific t code to populate them? I couldn't fid one online, although the SAP note i could find.
