That would explain it. :-)
I was trying to add a monthly bill, that is split on Rent, Heating and Cable TV, and every three months it also has Parking.
I will enter them manually for now then.
Is this already a planned future function?
How can I make a split scheduled transaction?
If I try to right click a split transaction and create a schedule, nothing happens.
And if I right click a scheduled transaction, split is grey and not selectable.
