Maintaining Control DataYou have activated the Tax Number 3 and Tax Number 4 fields in Customizing for Financial Accounting (FI), by choosing and ... Define Screen Layout Per Activity (Vendors).
On the Control Data screen, fill out the fields as follows:
In the Tax Number 1 field, enter the vendor’s INN.
In the Tax Number 2 field, enter the OKPO code
In the Tax Number 3 field, enter the KPP number.

Some companies have more than one KPP number. In that case, create a separate vendor master record for each.
If the vendor is a public body, enter its OFK number (see Entering OFK Numbers).
