Is there a way to create a dropdown in a sales order form from results of a saved search?

Your suitescript options depending on where you are doing it: Field.addSelectOption or Field.insertSelectOption

@battk Sorry I meant using a custom field dropdown not inside suitescript

wrong channel, buf if you are working with a non scripted field, than your suitebuilder option is Setting Filtering Criteria

@battk Got it. Thanks for that tip
