Key Figure in Days
I have a requirement to present a key figure in days. I noticed that in the KF infoobject screen I could model it as a quantity with either a fixed unit of measure of DAY or Unit/Currency of 0UNIT_DAY.
Could someone explain (in simple terms) or point me to good documentation that explains the significance and benefits of doing it this way. Which is best ie. fixed unit or Unit/currency.
I have currently modelled it as a number which uses a an ABAP routine to calculate the value.
Points will be awarded.
Thanx in advance
