3258078 - Error When Creating A New Individual Customer "Business Partner ID XXX Is Already Used By Account ABC"

When trying to import an individual customer to the system using Data Workbench, the system is showing the following error:
"Business Partner ID "xxx" is already used by account "ABC"."

SAP Cloud for Customer

1. Go to Data Workbench work center.
2. Open the Import work center view.
3. Attach your Excel file.
4. Select Import.
5. On monitor download the .csv file with the error.
6. "Business Partner ID "xxx" is already used by account "ABC"."

The system does not have specific number ranges.
All these objects as accounts, individual customers, contacts, competitors, partners and so on, share the same number ranges.

If you try to create an individual customer with ID "123" and a corporate account with the ID "123" already exists, the error message "Business Partner ID "123" is already used by account "ABC"." is raised.

 This is the system expected behavior.
