 🚀 Dynamics 365 Tip – Filtering Lookup Fields Made Easy!

Ever needed to filter a Lookup field in Dynamics 365 so users see only relevant records?

Here's how you can do it 👇
🛠 Scenario:
You want the Contact lookup on a custom form to show only Contacts related to a specific Account, Role, or Status.
✅ Solution:
Use JavaScript and addPreSearch() on the form to apply a custom filter dynamically.

💡 You can also dynamically pass GUIDs, roles, or custom attributes depending on business logic.

function filterContacts(executionContext) {

    var formContext = executionContext.getFormContext();

    formContext.getControl("your_lookup_field").addPreSearch(function() {

        formContext.getControl("your_lookup_field").addCustomFilter(

            `<filter type='and'>

                <condition attribute='statuscode' operator='eq' value='1' />

            </filter>`,

            "contact"

        );

    });

}
