Hello, 
I am currently on a project with Seblod, and I have a little problem. 
I want to know how to successfully recover the customer with just the customer number. 
I explain: 
-First, the user connects and can fill out a form 
-The first step is to enter the form number of a client (eg 12345) and then press Next to complete the following form. 
! And this is what my problem! 
I want that if the user enters a customer number already exists in the table then its coordinated form is written and unchangeable! 
is this possible? 
Thank you for your help 
cordially
