The error message you're encountering, "Function setCannotCancel is not allowed in scope x_syslt_iam," indicates a scope-related restriction in ServiceNow. In ServiceNow, application scopes isolate custom application data and prevent global applications from accessing the custom application data directly, enforcing data security and integrity.
Do you know where the function setCannotCancel is located?
If so, I would recommend to watch this video from Chuck https://www.youtube.com/watch?v=yx23wKB7uYM
