VAT Number Validation 

Use

The system checks VAT registration numbers in country-specific field checks. SAP has coded country-specific validations for European VAT numbers, which are used as a basis for these checks.

Activities

The UK VAT registration number is often printed with two spaces, for example, GB 123 456789, but we recommend that you use 11 characters instead of 13 characters for validation purposes. You can specify the rule used to check the maximum length of VAT numbers for GB company codes in Customizing by choosing SAPNet Weaver → General Settings → Set countries → Set country-specific checks. Select the country code GB and choose the Details button. On the next screen, enter 11 in the Length column and 1in the Checking Rule column for VAT registration no. Select the Other Data checkbox under Further Checks to activate country-specific VAT number validation checking and then save your entries.

If your business partner is a UK Government department or a UK Health Authority, deselect the Other Data checkbox under Further Checks as these bodies have VAT numbers that do not satisfy the general modulus 97 rule.
