Since MediaMarktSaturn (MMS) does not support B2B orders, the VAT ID is now stored purely for informational purposes in the Name 4 field of the address. This means that the VAT ID can be shown on the invoice without being entered in the dedicated VAT ID field in PlentyONE.

Note: The VAT ID is not automatically displayed on the invoice. You can define whether it should be displayed on the invoice in DocumentBuilder within your invoice document.

Background: Storing it in the standard VAT ID field would automatically trigger changes to price and tax calculation. Since this behavior is not intended for MediaMarktSaturn orders, the VAT ID is instead stored in the Name 4 address field, thus keeping it visible on the invoice without affecting order prices.
