SAP

No,
In fact, I believe SAP has a lot of value in business. If you're good ATIT you can land very good job offers after an initial struggle of 34years. However the SAP landscape is quickly changing so you need to be up to date with the latest in SAP. You could choose to go to the functional side which doesn't undergo as many drastic changes and involves a more direct involvement with business processes. If you want to go into technical, you should learn one of S/4 Hana, Abap on Hana, SAP Hana Cloud Platform, UI 5, Data or SAP Hana live (for business warehousing) apart from basic ABAP. The prospects are great after an initial learning period, however what nobody tells you is that you will mainly be stuck in the service industry only with SAP. Big shots like Google, Microsoft, Adobe use their own databases nor is SAP employed by startups like Uber, Flipkart, etc. The initial few years you won't be able to switch your company as nobody hires SAP folks without a good knowledge Base and 24 years experience. As the SAP market saturates it becomes a little more difficult. There are smaller higher paying companies like if you don't want to be in the usual Infosys, Wipro, Cognizant league, like Tietos and Itelligens too but then expect the working hours to be, well, not defined. So yes, scope wise SAP experience carries a lot of value and after a few years you will rake in the money to compensate for everything especially if you go abroad. But only do it if you are okay with being in the service industry and if you have the patience and learning desire to stay with it for 34 years in the same company before you start seeing results.
