Understanding Company Setup for Tax Reporting Entities
You must set up your reporting company with a value of 3 in the Person/Corporation Code field (data item TXC) in the Address Book Revisions program (P01012). When you set up the company with a value of 3, the system enables you to complete both the Tax ID (data item TAX) and the Add'l Ind Tax ID field (data item TX2).
You must complete both the Tax ID and Add'l Ind Tax ID fields or the system will not generate the Multi-Purpose VAT Communication. You can enter the same value for both fields.
