Hi,
If you don't intend to use many cubes: each for one year (it should be considered while a lot of data is going to be stored) I think you should rather choose selection 001.2015 - 016.9999.
Of course selection for all open periods (e.g. 012.2014 - 016.2014 ) should be considered.
For all selections run an init infopackage first otherwise you disturb delta loading.
