From SAP PI 7.3 to 7.4
I am in SAP PI 7.3 dual stack and worked in utility projects.
Now I am moving in 7.4 Java stack and its a retail project.
My question is -
1) What I need to know to move to 7.4 Java stack. Is it completely different or few knowledge regarding that is enough to work there.
2) What are the scenarios generally handled in Retail projects using SAP PI.
Experts please help ...
