Maintaining the Internet Address of a Customer 
The initial screen appears.

The address of the customer contact person is taken into account and not the business address. You can maintain the address directly in partner details. The system uses the postal address of the company (customer) for the address in partner details. You can maintain other communication addresses such as FAX or INT specially for the contact person.
Result
You can enter an internet mail address directly into the company address. Substance reports from the R/3 component Sales and Distribution can be shipped to this internet mail address.
