Access Control rules in ServiceNow define who can create, read, write, or delete records in a table or specific fields. These rules are applied at the table or field level and follow a specific naming convention:
TableName.FieldName
Why is the Correct Answer "incident.major_incident"?
Naming Convention for Access Control Rules:
If an Access Control rule applies to a specific table, its format is TableName (e.g., incident).
If it applies to a specific field, it follows TableName.FieldName (e.g., incident.major_incident).
Major Incident is a field in the Incident table:
The incident table represents the ITSM Incident Management module.
Major Incident is a specific field within the incident table.
To apply an Access Control Rule to this field, the rule name must be incident.major_incident.
Why Not the Other Options?
A . Incident.Major_Incident: ❌ Incorrect because ServiceNow Access Control rules do not use uppercase table or field names-they are always lowercase.
B . incident=>major_incident: ❌ Incorrect syntax-ServiceNow does not use => in Access Control names.
C . incident<=>major_incident: ❌ Incorrect syntax-ServiceNow does not use <=> in rule naming conventions.
D . incident||major_incident: ❌ Incorrect syntax-ServiceNow does not use || (logical OR) in Access Control naming.
