How to add Customer VAT number in Retail POS Receipt.

Hi There,

I am customizing Retail POS receipt and i need to add Customer VAT Number on Header.

In Receipt profile we have one field Customer VAT, which is picking the data from CustTable, VATNUM field.

I need to pick the Customer VAT number from TAXRegistration Table, but in retail store database i can't find TAXRegistration  Table.

Can you please guide me how to add customer VAT number in POS receipt.

Thanks.
