title: Adding output types to multiple sales orders, purchase orders, delivery or invoice
body: <p>Can anyone tell me how to use <code>RV_MESSAGE_INSERT</code> and <code>RV_MESSAGE_UPDATE</code> function modules to insert output types to multiple orders, deliveries or quotations at a single time?</p>
  
  <p>How can this be achieved? If I am using select-options as an input to get OBJKY (NAST table), how to achieve that? Any other ideas are welcome.</p>
