How can I set such validations 1. The "Date To" of an event should come after the "Date From" 2. The date should not be in the past 3. The amount should not be less than 0

Hello Arkadiusz Polus, in order to perform this kind of validation you need to write a little bit of code in the schema page. Perhaps this article of the academy will light things up for you.

what about business rules?
Arkadiusz Polus,
Business rules do not permit these operators >, >=, <, <=, so it would not be possible to solve these three cases that you mentioned earlier.
Maybe something that should be included in business rules in the future ? ?
