Hello @Suzy_Hyslip ,

 As per my understanding , it is normal field and its already present on Resolution information tab. It will not diversely affect on other forms .

Steps to create kb article

1)state=resolved , close notes and close code must filled.

2)saved.

3)check ( ✅ ) that knowledge checkbox 

4)when state goes to close state at that time kb article get created .

if this helps you then mark it as helpful and accept as solution.

Regards,

Aditya
