How to add author name while creating major incidents in knowledge

[udayakumar m]

While closing major incidents it's showing add knowledge if we clicked on that and later it's not showing author name in knowledge 

[Luke Van Epen]

This sounds custom, 

If you're talking about the "knowledge" checkbox, this is handled in the Business Rule "Incident Create Knowledge"

If you've got a button, you'll have to edit the button code to set it there.
