Tax Number ValidationYou can specify check rules for country-specific definitions. In the Netherlands, you have to set the check rule for VAT registration numbers. The system then automatically carries out formal checks on the length of these numbers.
To activate the checks, in Customizing for General Settings, choose Set Countries ® Set Country-Specific Checks. Set the VAT registration number length to 14 and the checking rule to 3. You can also set additional special checks to avoid input errors with VAT registration numbers by selecting Other Data under Further Checks.
