RE: Permanent date filter for orders today + 1 week day
Your date filter does not make sense.
If you want to filter any order that is due tomorrow, you just need to do like this.
..+1D
There is no need to use "or".
If you want to exclude weekends, there is no way to simply do this on date formula because you can't put conditional on date formula.
The only way is to code and assign the date formula based on the condition. Something like: if today is friday, filter until monday. else filter +1 day.
