We must access the application settings, and select the field in question (productid).

 

 

2. Next, we must change the type of the field to an auto-complete number, as it is of the type number.

3. Finally, we must configure the display lookup, using the products table to find the product names.

4. Next, we will create an ajax event (onChange) in the productid field, to find the unit price in the table when informing the product name.
