Hi all ! 

I'm planning to attend a SAP course but as they're so expensive I would have some suggestions by sap users.. I have no familiar with it so I need a preliminary overview and later a more detailed course. Do you think that is essential attending an introduction course in class or it could be easily attempt an online (cheaper) one? Regarding the selection, are there any specific course that you could suggest me ? I would improve my skills but I don't have particular needs, just knowing a little bit more about ERP. 

Thanks
