48 -== 3.4 Complete message mapping ==
31 +Navigate to Design and open the message definition option of at least one integration within your project.
32 +This assignment can be completed within the (Academy) project that you have created/used in the previous assignment.
49 49  
50 -Now that you have completed these steps, go to Message mapping and complete the mapping.
34 +== 5. Key takeaways ==
51 51

53 -
36 +* A message definition is a visual representation of how the elements are related to each other, whether they are mandatory and the data types they have that can be used in the message mapping
37 +* Some message definitions are specific to a system. Others are generic across systems
54 54  
55 -== 4. Key takeaways ==
56 56  
57 -* The CDM holds all entities and attributes that are relevant within the context of your complete integration landscape.
58 -* The CDM message is tailor-made for a specific piece of data and only holds the entities and attributes relevant for that piece of data.
59 -* A system message is specific to a system.
