Final answer:
To enable Script Includes in the HR application, the ARCA status must be set to Allowed, which allows calls from other scopes, and custom ACLs may need to be created or the scope adjusted if necessary.
Step-by-step explanation:
The question you've asked pertains to configuration within a ServiceNow HR application or a similar platform that uses Script Includes. To allow the Script Includes to work properly in the HR application, one of the things you can do is adjust the Application Restricted Caller Access (ARCA) settings. Specifically, the status of the associated record on the Application Restricted Caller Access list must be set to Allowed. This is because setting the ARCA status to Allowed permits the Script Include to be called from other scopes, which is necessary for it to function as intended.
On the other hand, changing the status to Denied would prevent the Script Include from being called by applications outside of its own scope. Creating a custom Access Control List (ACL) can also be necessary, depending on what the Script Include needs to do and whether the default permissions allow for those actions. However, in some cases, simply changing the scope of the Script Include could suffice. In summary, the correct setup would mostly likely involve setting the ARCA status to Allowed and potentially creating custom ACLs or adjusting the scope as needed, depending on the specific requirements of the Script Include's functionality within the HR application.
