Sample code for overriding the default server call that generates the type-ahead for an Item Field

FilterItemField.js

// Get the field we want to populate dynamically
var item = getFieldComponentByName('owned_by_id');

// Override the default server call
item.component.request = function() {
	var itemType = this.state.itemType;
	var maxCount = this.state.maxItemsCount;
	var label = this.state.label;

	var req =
	'<Item type="' + itemType + '" select="keyed_name" maxRecords="' + maxCount + '" action="get">' +
		'<keyed_name condition="like">' + label + '*</keyed_name>' +
		// Add our extra filters to this call
		'<is_alias>1</is_alias>' + 
	'</Item>';

	return ArasModules.soap(req, {async: true});
}
