Vendor Duplicate check messages 144, 145

Dear Team,

We want to check duplicate check for Vendor. We have ECC. Before implementing SAP Note 2005187, SAP Note 2005206, SAP Note 2005203, do we need to activate messages in ECC in OBA5 or SPRO>> Financial Accounting(New)->Accounts Receivable and Accounts Payable->Vendor Accounts->Master Data->Preparations for Creating Vendor Master Data->Change Message Control for Vendor Master Data.

Shall I more Idea on below points:

1. Whehther it will check for some field like name, address of vendor

2. It will chekc while transferring

Regards,
