How to merge data from multiple services running in multiple systems (multiple origin)

This blog will analyze how to achieve data merging of different two back end systems, we can assume the following scenario.


1. Step 1 : Create a Gateway builder project in SEGW in both CRM and BW with same EDM model.


2. Step 2 : Implement the data providers in CRM and BW systems.



3. Step 3: Register the service in GW Hub (from one system at-least)


4. Step 4: Assign the system alias of both CRM and BW in GW Hub.


5. Step 5 : Test and consume the services.
