3436181 - Error "Employee ID XYZ already exists" While Replicating Employees To SAP Sales & Service Cloud Version2

1. Go to Webservice Monitoring
2. Check the failed employee replication with error "Employee ID XYZ already exists"

Employee with same ID already exists in the system, created manually or imported via some other source

When an employee is replicated from S4HANA/ERP/EC to V2 system , we send the Employee ID as both "displayId"(ID from External System) & "receiverDisplayId"(Internal ID of V2). Employees Internal ID & External ID should be same in principle. Then if an employee with same Internal ID exists , system will trigger this error message.

To fix this issue, create the ID Mapping manually and reprocess the failed message.
