I am trying to find a good place to start for a potentially SAP related project. Suppose I wanted to develop stand-alone software that could connect with an SAP ERP (S4/HANA) system and analyze material management and accounting data. What resources would I need to accomplish that? Where could I get an SDK/the proper training for this? How would I get a system to experiment on? I've tried Googling this question but there doesn't seem to be clear authoritative information on this and what I find also seems to be mostly about SAP Business One, which is a different product.
Insights would be much appreciated!
Thank you in advance, Joshua
