Hi Florian,
You've managed to use all of the same ambiguous words that appear on the dialogue box in a slightly different order.
Can you describe a real world scenario where this would provide some different or extra behavior than specifying the Valid From / Valid To columns? The UI is designed in such a way that these parameters are required but I'm not clear what extra benefit this would provide. In our case the validity period *is*the Valid From / Valid To columns.
Thanks,
Zach
