I am working for the last 15 year in Automotive area, being part of a large IT Team. I've started to work in SAP in the last 5 years and because the tasks changed very much lately, I had to move my interest to learn how to connect C# applications with SAP.
In this period, I have worked with SAP functional consultants which taught me what to search for when I'm developing applications. But because in this area is only a few documentation, I had to do a lot of research in order to get to the proper results.
SAP, like other software, needs practice and proper training. In my courses I will try to help you have this.
