AFFW records <> COGI!

Hello dear SAP gurus and friends,

I have a question regarding table AFFW and transaction COGI. How its possible that I have records in table AFFW and not in transaction COGI?

By others words, there are records inside the table AFFW that did not appear in transaction COGI. Is there a way to delete this records, and if yes, is it safe?

Thanks for your time.

Best regards,

Adelmo Silva
