There are different ways of getting acquainted with SAP Data Warehouse Cloud: you can read the guides on the Help Portal, you can browse the community, or you can just get started playing around in the system. When you are in the system, you might come across the in-app help, which is accessible via the question mark in the upper right-hand corner of the screen. In addition to descriptive texts, you will also find guided tours and video tutorials here.
I have also collected our videos (made by user assistance) in a library on the Help Portal for easy access from outside the system. This library is updated constantly, so check it regularly if you like learning from videos!
