Black list declaration in SAP

Hi everyone,

I have recently learned about the black list declaration report which is elementary for Italian reports.

Could you please tell me more about its:

Definition / Utility for business,

What does it explain / report?

What are the steps to implement in SAP this black list declaration?

What are the main functional steps and customizing? Especially when the company has to buy and sell with intercompany codes from other countries

Thank you in advance for your help

Kind regards.
