E1 9.2 Field Entry Validation without customization

Hi,

Has anyone work with field validation in 9.2 with the new features?

We are looking if there is any feature in 9.2 to control the data entry in the form. I try to explain myself .. we are trying to add some validations in the data entry but in the standard (for example, if the user choose order type XX the Tax Area should be YY or something like this) we can perform an alert telling the user that the data are not correct but we are looking for something in the moment when the user add information in the system

 

We want to avoid some little customization with features from 9.2 we have look into the Form Extension that it is really powerful, but we missed something like validations or little controls … and maybe you can help us or tell us where to look
