Hello Janisero, thanks for your reply. I created you 3 screen captures.
At screencapture1 you can see the Contact details with many custom fields I created.
At screencapture2 you can see the products related module to Contacts.
My goal is to show fields from related product at Contact details. It’s to say, I need to show a field like “CÓDIGO FARMACIA” that belongs to product module, at a field inside Contact details (screencapture1).
The other goal is: when I need to add a new related product to contact, I click on select and appears a screen like screencapture3. I need to show fields from contact in the search result grid. Now at result grid only appears fields from products, but I need to show data from related contacts of each product.
Do you know if I can do that anyway?.
Thanks a lot for your help.
