On-call calendar showing incorrect results when sys_user record has schedule field populated with a Resource management schedule. Issue When viewing the On-Call Calendar, the system is displaying the incorrect user to provide coverage for a shift. When trying to select a specific user from a Roster to "Provide Coverage" the system keeps inserting the same incorrect user each time. This issue is also happening when trying to schedule time-off through the On-Call Calendar, the system just defaults to the wrong user. ReleaseQuebecCause- Observed that the schedule field of the user records is populated with "Resource Allocation 10 Hours Per Week". This field should be empty in order to on-call scheduling to work fine.- Test by clearing their schedule field and reproducing the issue, should get resolved then. - However, for customer organization to properly gauge capacity on project/enhancement work, they are leveraging Resource Management. If we set users schedules to 0, that defeats the purpose of using Resource Management since we won't be able to see availability. - As per https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0715326But it should be fixed in current customer release. Resolution- As per PRB684820, below are the steps of what needs to be done -If a user is part of both On-call and resource management, please use user_has_schedule("schedules" related list on the "Resource Manager" view of User form ) table to populate resource management schedule. Schedule field on the user table will be used by on-call and it would create a separate schedule for each user.Resource management would look at entry in "user_has_schedule" first, if it is not present, it will look for schedule field on user record. By creating a record in user_has_schedule for that user, resource management should work properly.In this customer case, they have to populate the "Resource Allocation 10 Hours Per Week" schedule in user_has_schedule table for all the users and clear off the schedule field on the User form.Related Linkshttps://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0715326
