An Access Control list (ACL) defines what data users can access and how they can access it in ServiceNow tables1. The ACL evaluates the user roles and the conditions defined in the ACL rules to determine the user's access level2. In this case, the ACL rules for the table are as follows:
* table.None read Access Control for users with the admin and itil roles: This means that users with the admin or itil roles cannot read any field in the table unless there is a more specific rule that grants them access3.
* table. * read Access Control for users with the admin role: This means that users with the admin role can read all fields in the table.
* table. field3 read Access Control for users with the itil role: This means that users with the itil role can read only the field3 in the table.
Therefore, a user with the itil role can read only the field3 in the table, and not the other fields.

A report is a graphical representation of data from one or more tables in ServiceNow. The following are true for reports in ServiceNow:
Can be a graphical representation of data. This is true because reports can use various chart types, such as pie, bar, line, or gauge, to visualize data in a meaningful way.
Can be run on demand by authorized users. This is true because reports can be accessed from the Reports menu or the Report Navigator and run by users who have the appropriate roles and permissions to view the data.
Can be scheduled to be run and distributed by email. This is true because reports can be configured to run at a specific time and frequency and send the results to one or more email recipients.
The following are not true for reports in ServiceNow:
Any user can see any report shared with them. This is false because users can only see reports that are shared with them if they also have access to the data source of the report. For example, a user who does not have the itil role cannot see a report based on the incident table, even if the report is shared with them.
All users can generate reports on any table. This is false because users can only generate reports on tables that they have access to and that are enabled for reporting. For example, a user who does not have the admin role cannot generate reports on the sys_user table, which is the table for user records. Reference: Reports, Report Security
