<h3>VAT number check level 2: wrong behaviour during return code 1511 and 1513</h3>
<div>If a VAT number-relevant master data has been changed for the person and the following VAT number check was successful, the check code 1511 or 1513 was not successful. This change has slipped through the next check and has not been recognised anymore. The behaviour has been adjusted. A master data change is still recognised and taken into account in a later successful check. </div>
