Identification
Numbers 
Key figure, which is issued by an institution for administrative purposes (for example passport number) or by a business information company such as Dun & Bradstreet, and is used for identifying a business partner.
You can enter as many identification numbers as you like for each business partner during maintenance, in order to determine a business partner as precisely as possible. Select the corresponding identification number type using the F4 help, and assign the identification number.
In addition, you can use the search help to determine a business partner by means of identification number or identification number type.
The change history allows you to display the change information for an identification number.
In the Implementation Guide (IMG) you are free to choose which identification number type you set, for example: Dun & Bradstreet, passport or driver’s license number.
Make these settings, as well as settings for the identification category in Customizing of the Business Partner under Basic Settings ® Identification Numbers.
