Create a custom field validation
A question had once been raised in the community regarding customizing a page.
What I need is that on the Dispatch List Revision page I can customize the validation of the "To Transact" field so that it is less than or equal to the "Required" field.
I read the documentation they sent me, but when testing the syntax, it was not possible to produce an error message, or show the user that there was a problem to be fixed.
Here are the syntaxes that my team and I tried to execute:
#{
if(row.RequiredQuantity != row.TransactionQuantity){
throw new ValidationException("TESTE")
