Depends what you mean by 'technology.' If you're limiting yourself to computers, IT, and even electronics you'll be continually challenged because of the rapid changes. However, if you're talking about the sorts of courses taught at technical colleges (in Australia, anyway) then it's a wider field. Some services are always needed and the people who can provide those services can usually find work just about anywhere, e.g. the trades such as carptenter, plumber, electrician, bricklayer, tiler.
Then there is the health services, nurse (male or femaile) radiographer et cetera.
Even if you do not plan to make a life-long career of any of these, it pays to have a qualification in such areas as a fall back. Take a look around. Note all those pick-up trucks and vans the tradesmen drive. Sure there's a lot of them. But there is a lot of work for them, too, as a rule.
I could be right off target here, for I don't know what you're really after...and I don't even know what SAP is. But whatever skills you do decide to learn, and whatever experience you gain, be sure to 'go with your heart' when it comes to the greater part of your work. Being content and enjoying the job is far more important than either the status or the pay.
