Add additional exercises

[BNAndras]

I might have an opportunity to work with some ABAP code later this year so this is a good excuse to add some more exercises over the next couple of weeks / months if the maintainers are interested. I'm in no rush to get these reviewed or merged so you can deal with these at your own pace. :)
