External Credit Data 

Allows you to enter credit data about a customer from external sources. The standard version of the SAP System is set up for Dun & Bradstreet data. For example, you can enter the D & B credit information number (DUNs number) that refers to the customer, as well as the D & B indicator and rating. You can also see how up-to-date the external information is by entering the date you last acquired data.
