Finally, I have the Developer Studio going and working for PI 7.31 and I was testing the message mapping of it. This experience had given me an edge in learning the message mapping. In the video, I look into message mapping definition. I explored the mapping as I go on. The layout of the mappings seems easy and organize with the help of Eclipse based mapping tool.
I was exploring the context of mapping but having a hard time in looking for it. I must admit that the tool you see on the video can be optimized for mapping documents. Its hard to determine and learn each functionality of a mapping especially if the context is not present. It hinders you from doing testing.
Check out the video and see how it looks like.
