Security prevents writing to this field

I am brand new to ServiceNow and working through the course, Welcome to ServiceNow. One of the exercises is to update Incident INC0000055 category to Software. However, when I try to do that, I get, "Security prevents writing to this field."

Therefore, when I try to Validate the task, it fails because I haven't done this.

I have looked at responses to similar questions and they talk about ACL. But, like I said, I'm brand new and have no idea what ACL is. Besides, I would think that ServiceNow Learning would have the exercise set up so that I could actually complete it?

Thanks for your help!

Hi @louiserp 

 

Check in the top-right corner that you're logged in as the System Administrator, and that you're not impersonating another user:

If you're impersonating a user, they may not have the access required to update the incident, but the Admin does.
