BP and Customer Master Data CVI Functionality

[ahmet_berk]

Hi

I create a business partner(for customer data) and I want to extend it to customer for sd.

I selected customer(New) in Create in BP Role field but sap (version16.10) said to me business partner 90000053 already exits. I thought that I can create it but it said it already exist.

In ECC, I could extend to customer data(customer number) in sd area company code in the past.

Does BP funcionality be so different from the ECC version? I thought that They are in the same rule.

Can you help me to understand this bp functionality?
