Anyone use SAP software where they work?

Guys I am job hunting and a lot of jobs I am looking at say they prefer someone with SAP experience. Anyway what exactly is it, and is it that difficult to learn. I have a IT degree so I am guessing it is like any other software that you use. After a few times you get the hang of it easy.
Answer #1
Yes, it depends in which branch of the industry it’s used.Mainly to be used to scan incoming, outcoming goods, stock and so on.It gives Companies a global view, a bit outdated.
Parcel services use it too, digitized signature by delivery…..
