In the start, SAP NetWeaver was very difficult for me, but now I feel it is very easy using the solution. On a scale where one is a difficult setup, and ten is an easy setup, I rate the setup a ten. I have done deployments, taking around a year. Regarding deployment, there were some configuration issues that I have told my business consultant about since when I'm working, I face certain issues. There are many things related to Java and a few other things. So, some Java libraries are missing, and other crucial things are missing. I faced many issues when we were deploying the solution. The first time, I didn't know about the deployment. So, it felt very complicated since it was not working properly. I think these issues belong to business consultants. Also, configurations and solution-related issues fall upon the business consultant. But when we are working as a developer on it, then we face many issues, and we raise the ticket to SAP or a consultant to resolve it. Some Java directories are missing, and some SAP Connectors are missing. Also, some of the connectivity is not proper. Most of the time, components and channels are not available for us.
