When Approver try to approve "Add Global Assignment" system throw error "Error occure while saving global assignment".
Employee Central: Global Assignment
This issue occure due to wrong HRIS Mappping for person id and user id field.
Please download succession data model and remove the HRIS mapping between Person-id-external and user id. You cannot sync the person-id-external to the userId since the person-id-external is unique for a person and the userId is unique per employment. Therefore, the system tries to set the userId of the global assignment to be the same as the one of the original employment which causes the operation to fail. If you do not have access to Provisioning, please contact your implementation partner or Cloud Product Support.
