Hi @sikhasarmah  ,

 

Create an ACL you should have 

  1. Elevated privilege roles to the security_admin role.
  2. Navigate to System Security > Access Control (ACL).
  3. Select New.
  4. Complete the form.
    Field Description
    Type Select what kind of object this ACL secures. The type of object determines how the object is named and what operations are available. This field becomes read only after the ACL is created. If you want to change the type, you must delete the ACL and create one with the correct type.
    Operation Select the operation that this ACL secures. Each object type has its own list of operations. An ACL can only secure one operation. To secure multiple operations, create a separate ACL for each.

    If you’re creating an ACL for a report_view operation, see also Report_view access control.

    Decision Type Select the decision type of the ACL. Allow If allows access upon successful evaluation. Deny Unless denies access unless there’s successful evaluation. See Deny-Unless ACL for more information.
    Admin overrides

    Select this check box to have users with the admin role automatically pass the permissions check for this ACL. Admin users pass regardless of what script or role restrictions apply. However, the nobody role, which only ServiceNow personnel can assign, takes precedence over the admin override option. If an ACL is assigned the nobody role, admin users can’t access the resource even when Admin overrides is selected. See Base system roles.

    Clear this check box if administrators must meet the permissions defined in this ACL to gain access to the secured object. Since administrators always pass role checks (see the description of the Requires role field), use the condition builder or Script field to create a permissions check that administrators must pass.

    Protection Policy Select this to set the protection policy on the ACL.
    Name Enter the name of the object being secured, either the record name or the table and field names. The more specific the name, the more specific the ACL. You can use the wildcard character asterisk (*) in place of a record, table, or field name to select all objects that match a record type, all tables, or all fields. You can’t combine a wildcard character and a text search. For example, inc* isn’t a valid ACL name, but incident.* and *.number are valid ACL names.
    Note: 
    Select the blue triangle to manually enter the record name or the table and field names of the object being secured. Use this option to secure an object that doesn’t appear in the dropdown.
    Description Enter a description of the object or permissions that this ACL secures.
    Applies To Select Add Filter Condition to create a filter for the table selected in the Name field. The ACL applies only to the records matching this filter condition. For example, you could create an ACL for the incident table that applies only to incidents with the Critical priority.
    Note: 
    You must select a table in the Name field to use this option. ACLs beginning with * cannot use the Applies To filter.
    Active Select this check box to enforce this ACL.
    Advanced Select this check box to display the Advanced Condition fields. See step 6.
  5. Optional: To narrow the scope of the ACL fill in the Conditions fields as necessary.
    Requires role Use this list to specify the roles a user must have to access the object. If you list multiple roles, a user with any one of the listed roles can access the object. The Requires role list appears as a related list. If none of the roles you add exist on the instance, the system will deny users access to the object.
    Note: 
    Users with the admin role always pass this permissions check because the admin role automatically grants users all other roles.
    Security Attribute Condition Use this section to define what the user can access based on user and environment criteria. For more information, see Security Attributes Fundamentals and Security Attribute Type.
    Note: 
    The Condition field is case-sensitive.
    Data Condition Use this condition builder to select the fields and values that must be true for users to access the object.
    Note: 
    The Condition field is case-sensitive
  6. Optional: If the Advanced box is checked, fill in the Advanced Conditions fields as necessary.
     
    Controlled by References Enforces the ACL on related records. See Related record access for more details.
    Script Enter a custom script describing the permissions required to access the object. The script can use the values of the current and previous Global variables in business rules as well as system properties. The script must generate a true or false response in one of two ways:
    • return an answer variable set to a value of true or false
    • evaluate to true or false

    In either case, users only gain access to the object when the script evaluates to true and the user meets any conditions the ACL has. Both the conditions and the script must evaluate to true for a user to access the object.

    If there’s a script in the Script field, this script executes even if the field isn’t displayed on the form.

    Note: 
    If the evaluated item is in a related list, current points to the item the related list is on, not to the current item the ACL is for. However, If the item you’re evaluating the ACL for isn’t in a related list, current points to the actual item.
  7. Select and hold (or right-click) the form header and select Save.
