How to find an ACL for a field

[juliochacon23]

He, we recently upgraded to Helsink and now we are unable to modify the Approval field in the CCR form.   We get the below error.

Error: "Security prevents writing to this field."

How do I figure out what ACL is causing this so that I can modify this?   Is there a tool in ServiceNow that can tell me what ACL its using?

Thanks

1. Elevate role to Security Admin

2. Right click on filed and show security rules.   These will be all the rules which apply to the field.   Generally, you want to look for the rule at the field level, e.g., task.priority.   The part following the period.

This helped me, thank you Bill!

Thanks, but I don't get these options when I right click the field.   See below screenshot.   I don't think this is a regular field.

That looks like a list edit.   Right click the field from the form view.
