This might be a bit vague question, but real life is like this.
Our company is rolling out SAP system. I know they now do Web Services so we could simultaneously roll out the .NET thing for anything we know we can do in C#.
What are the pitfalls along the way of SAP – .NET integration? I understand that SAP’s logic is quite different from “standard” programming, but I hope to separate “business” part from “presentation” part, to be written in ASP.NET.
If your apps dont require SAP Portal integration and your clients dont ask for SAP-like look and feel then you are free to use whatever presentation layer you like.
I disagree with the stance that you have to use sap tools when you choose to do a SAP integration. Products like NWDI or old NWDS are a clear headache (im not gonna elaborate on that here, its a long story), training people to learn Webdynpro is in my opinion not worth the money if you arent a 100% dedicated sap integrator.
