In this step, you will add the elements for the Customer entity. Some elements will be defined using Data Types and some elements will be defined manually.
The Customer entity will have the following elements: Customer Number, Customer Name, Address Line 1, Address Line 2, Address Line 3, Address Line 4, Postal Code and Country.
Note: If you compare the Customer Entity to the one in the sample, you will see that it has a different structure. In tutorial LMG004, you will transfer some of these elements to a Conceptual Entity and use relationships to include them into the Customer Entity so that it matches the sample model.

7. The Customer Number element will be added to the list of elements and the Create Element window will be redisplayed.
