Maintaining Control Data 
On the Control Data screen, you maintain a range of information that is used for tax reporting purposes.
You have customized the account groups so that the Representative’s Name, Type of Industry, and Type of Business fields appear in the master records. You do so in Customizing for Financial Accounting (FI), by choosing Accounts Receivable and Accounts Payable ® Vendor Accounts ® Master Data ® Preparations for Creating Vendor Master Data ® Define Account Groups with Screen Layout (Vendors). Maintain the field status for the Control Data tab, and set the Business Place field group to Req. Entry (Required Entry).
In the vendor master data, on the Control Data screen, fill out the fields as follows:
· Tax Number 1:Corporation ID (legal persons) or personal identification number (natural persons)
· Tax Number 2: VAT registration number
· Representative's Name
· Type of Industry
· Type of Business
If the vendor is a natural person, select Natural Person.
These fields are used in the VAT Summary Report and in income tax returns (see Generic Withholding Tax Reporting).
