It may not be shown in iDrive, but it is in the manual, where it says:
Requirements (for detailed oil measurement)
▷ Vehicle is on level road.
▷ Steptronic transmission: selector lever in
selector lever position N or P and accelerator
pedal not depressed.
▷ Engine is running
and is at operating temperature.
