How to retrieve fields from related list for a client script?

[Aeden Frost]

Hi everyone, hope you're all having a nice day.

I'm trying to run a shipping cost calculator in my instance and I was wondering how I would go about getting fields from a related list into the current list that I want to run client scripts for.

I have a volume field on the consumable model form and I want to import it to the product catalog form to run calculations from there to get my shipping cost.

Thank you very much for your help!

You have to resort to GlideAjax calls here, you have to write up a client script and make a ajax call to client callable script include. In the script include you can glide the related list table and fetch the information that you want.

Refer to Async GlideAjax in below article:
