GOpus® TIN Check

VAT ID validation for SAP ERP and SAP S/4HANA

VAT ID validation in your SAP ERP and SAP S/4HANA

Legal requirement:
According to the legal requirement the movement of goods within the EU is only exempt from sales tax if a valid sales tax ID is provided. In 2020, this regulation was tightened, so that the VAT ID no. now mandatory is to get the tax exemption.

Our solution:
Our solution is based on the SAP system of an EU-based company and enables the online request (individual or collective check) for the validation of the VAT ID to the European VAT Information Exchange System (VIES). Depending on the data protection regulations of the requested country, the GOpus® TIN Check either a qualified or a simple validation of the VAT ID.

The qualified check provides additional company-relevant data such as the company name and address for comparison with the master data in the SAP system. If the result of the check is invalid, you have the option of setting optional locks in master data and processes (customer master, vendor master, central business partners, sales documents and orders). Furthermore, the test results for transaction data can be stored in an audit-proof manner via SAP ArchiveLink.

Communication takes place via a secure HTTPS connection, whereby it is not necessary to set up an RFC connection in SAP. Instead, a direct connection is used via a consumer SOAP web service interface, with only data being transferred in XML format.
