Re: An error has occured. In a dynamic filter, cannot compare fields of different da

if one field is a VALUE and another is a TEXT then you can get this sort of problem

but if you’ve got another report using the same method, check there to see what is potentially different ?

also.. what sort of ‘filter’ are you using? there are many ways you can work with filters. in the datasource, using Filter Input/Selectors and also in behaviours as well
