Fetch options for select field

I added two contacts for a supplier.In purchase order I have a select field “contact”.If select a supplier need to get supplier contacts as options for field contact in purchase order.How?

Please check it.

I need all contacts added for that supplier as options for purchase order contact select field.

Here right?

You should use the Overriding Link Query By Custom Script


Here when i select supplier I need that supplier whole contacts in supplier contacts options

Customization and logic are required.

reference:

How to get selected supplier contacts in purchase order through client script

You have to customize it in your own way by lifting the logic from the reference I gave you.

ok.thanks
