I guess there must be a lot of opportunities in the SAP ecosystem (edit: or replacing said ecosystem), but I haven't seen it myself and it's VERY closed, there isn't even good reference material out there (and official training is quite expensive). Though I just Googled and it doesn't seem to be that bade anymore, I found they lauched openSAP https://open.sap.com/ https://open.sap.com/ though it doesn't seem to have any useful courses for beginners (I guess they don't want to kill their partners' cash cow) and an Udemy course https://www.udemy.com/learn-sap/ https://www.udemy.com/learn-sap/ In my country learning SAP / ABAP is seen as a fast track to a good salary (if you can find one of the limited job opportunities). I've been passed over for a good opportunity for not knowing SAP basics.
