How to filter an OVS in list?

Hello,

I am trying to make a filter to an extended OVS based on product ID in new purchase order.

I've created this OVS from a Custom BO. the Custom BO has a number and product id (few catalog numbers can be assign with the same product ID from the database).

so when i choose a random Product ID, i want to see only the relavent Manufacture Cat NO. in the OVS.

how can i do that? here is a picture to demonstrate.

Thank you,
