During CVI in ERP and when trying to convert a Vendor to BP, we get an error that duplicate Contact Person BP's are created.
Step 1. Vendor is having Contact Person and we are creating a Business Partner Vendor from MDS_LOAD_COCKPIT
Step 2. Due to an unexpected error in Tax Category, the BP Vendor is not created. But in background a BP Contact Person is created and it is available in BUT000.
Step 3. The BP Contact Person do not have a relationship as BP Vendor was not created in step 2.
Step 4. The error in vendor is corrected and again synchronized from MDS_LOAD_COCKPIT, this time a BP Vendor is created as expected, but this time an additional BP Contact person is also created with relationship with BP Vendor.
