3266815 - Error Message "Number <CENTRAL_PERSON> is already assigned to partner <BP number> for ID type HCM033" Displayed After Replication

When updating worker information in any channels, the following error message raised:

"Number <CENTRAL_PERSON> is already assigned to partner <BP number> for ID type HCM033"

Message no. R1477

 SAP S/4HANA Cloud

You already have an employment BP, but the supplier role was added manually to employee BP instead of employment BP. As per the New Business Partner Model, supplier role should be part of employment BP. When you perform any update for this worker afterward, you will get this error because ID type HCM033 is part of a separate employment BP, but the supplier role is incorrectly added to the employee BP.

For successful replication, remove the supplier role from Employee Business Partner. After that add the supplier role to Employment BP automatically by sending payment information during employee replication (recommended way) or add the supplier role to Employment BP manually.

You can follow the steps mentioned below to archive supplier role from Employee BP first. (Role Requirement: SAP_BR_DATA_PRIVACY_SPECIALIST role is required to view the applications mentioned below.)
