function onAction(context){
var itemRec = context.newRecord;
var itemId = itemRec.id;
var item = record.load({
type: record.Type.ASSEMBLY_ITEM,
id: itemId
});

    item.setSublistValue({
        sublistId: 'itemvendor',
        fieldId: 'vendor',
        line:0,
        value: 101
    }); //value is a Vendor internal ID that you want to set as preferred

    item.setSublistValue({
        sublistId: 'itemvendor',
        fieldId: 'preferredvendor',
        line:0,
