Summary:Unable to add/modify/delete Work Schedule for one employee in Work Schedule Assignment page. I also checked transaction console page but there are no stuck transactions. I have also run Employment Diagnostic Master report and fixed it. But still i am unable to add any Work Schedule for that employee. We are able to add the resource via Work Schedule Assignment Administrators page and the same we are able to see in employees Work schedule. We are getting ADF error when we are updating work schedules via person Management»Workschedule assignment page
