I have to write an ABAP program to check VAT numbers before making any VAT declaration. SAP checks the logic of the number, however it does not check if a VAT number is still valid for that company. The European Commission has a website (http://ec.europa.eu/taxation_customs/vies/) where you can check centrally all VAT numbers used in the EU. According to the Commission's web site it should be possible to have an open interface. A SOAP service is available (Its WSDL file can be obtained also on the website).
Does anyone has an idea how this can be done (Current SAP version = SAP ECC 6.0) taken into account there is no XI (or IP) aviable or set up or used.
