If the sn_hr_core.impersonateCheck system property is changed to True, impersonating a user to complete HR Tasks user may find themselves unable to access some dataIssue A client script was not populating the fields as expected for a HR Task on HR Portal. Customer was impersonating the user that the task is assigned toOpening the HR Service Portal (in nav) or /hrportalGo to My HR To-dosClick on the task in the list In a reference field they had the option to select a user, you can pick any user.Expected: The client script populates the other fields automatically based on this user. Actual: Nothing populated. It seems the issue was happening only when impersonating due to the above system property. When the user actually logs into instance (as opposed to impersonating), this issue should not happen even if the property is set to true.CauseThe HR impersonate check system property was set to true in the customers instance. This property makes sure that users can access HR information only when they actually log into the instance and prevents the access if impersonating.https://<instancename>.service-now.com/nav_to.do?uri=sys_properties.do?sys_id=7a5330019f22120047a2d126c42e70f0ResolutionAfter setting this property to false, can no longer reproduce the issue.
