Is there someone who didn't have the case to verify that a field value is unique per form type/business entity/step(s)? I for my part now, did implement this dozens of times
Finally, I realized, that I should streamline this approach and create a business rule for this. Even if it's easy to create the check, the business rule will force you to think about each parameter
You can read up on the business rule and the parameters: here.
But it shows again that WebCon is a poor tool as low-code. So many business requirements can be done only via SQL, JScript and with lot of tricks...
And what is a big disadvantage that you can not support yourself with any AI tool. It can be done aside but not within Designer Studio... It is closed solution, not modern and ... not good because of that.
