How can I convert the person-id-external (Person ID) of existing employees?

[AndyBoolean]

Hello everyone,

According to the SAP Help documentation here, changing the person-id-external is allowed for existing employee data.

I have two questions about this:

• How and where can I change this person-id-external for existing employees?
• What are the restrictions?

I have searched SAP Help and SAP Notes on this topic and found nothing.

Thank you for your help 😄

Best regards,
Andy

Hi,

Never needed to update the person ID external but the note referred to below by pboulicaut mentions API ConvertAssignmentIdExternal.

We have used this api to update our external assignment Ids via an integration in CPI which takes a file of old/new numbers and does the update

Hi bg,
I would like to convert the person-id-external.
I know the conversion with the assignment ID in self-service.

Best regards,
Andy
