I'm trying to attach a Work Order to a Transfer Order using the following,

recordModule.attach({
    record: {
        type: recordModule.Type.WORK_ORDER,
        id: workOrderId
    },
    to: {
        type: recordModule.Type.TRANSFER_ORDER,
        id: transferOrderId
    }
});

Error:

TypeError: Cannot find function attach in object standard record.

Am I correct in calling

recordModule.attach

?
