I have couple of questions.
1) How to handle sender proxys across different systems (DEV , QA , PROD)
do we need to create proxys in each systems or is there any way to
transport them across different systems.
2) Is it good to have one namespace for each scenario under a software
component or is it better to have one component per scenario
1. Ususally it is transported in thesimilar manner in which any other ABAP object is transported.
2. The abstraction of Software Componenet and namespace depends upon the complexity of the system integration landscape. If ur scenaio involves many interfaces, then the logical distinction can b done by creating several Software Components. If it involves just 2-3 interfaces, it is better to go for one SWC and 2-3 namespaces.
