Hi,
I want to validate that my agreement period (agreement entity) does not overlap with a renewal period (renewal entity) the relationship is 0,N between the two entities.
So, I need to get all renewals from the Renewal entity for my agreement and for each registration, I need to check if my agreement period does not overlap with the renewal period.
And I also have to check that the period of the agreement is not smaller than the first renewal period.
Is there a way to do that without programming in javascript a validation?
