How to Block Duplicate Record?

How to block the creation of a record through the record producer if the user has already made a request for the same record (course) and on the same date

[Rafael Batistot]

Hi @RobsonG10844545 

The best way is create a Business Rule > before > insert 

See an example of code 

var dup = new GlideRecord('u_course_registration');

    dup.addQuery('u_requested_for', current.u_requested_for);

    dup.addQuery('u_course', current.u_course);

    dup.addQuery('u_date', current.u_date);

    dup.query();

    if (dup.next()) {

        gs.addErrorMessage('You have already requested this course on this date.');

        current.setAbortAction(true); // If true,  will be aborted the record producer creation 

    }

This is an example, kindly send the names of fields from the form to give an code more correct

@RobsonG10844545 ,

By writing a Before Business Rule on the target table that queries for an existing record matching the user, course and date, and if found aborts the insert (for example by using current.setAbortAction(true) or setting an error) so the duplicate is prevented....try this out..
