ABAP CL_RSAR_FUNCTION class in BW4/HANA

I wrote about the ABAP class CL_RSAR_FUNCTION a long time ago here. In a nutshell it provides a collection of static utility methods for common data transformations and calculations, particularly focused on date and string operations. The methods can be called directly without instantiating the class.

Now in a BW4/HANA based BW system there are few more methods added into the class.
