Gateway Batch Calls from SAPUI5

One of the features available with the latest release of the UI Development Toolkit for HTML5 (1.8.4) is the ability to batch multiple OData operations into a single call.

I thought I would share a quick example of how its done.

Below is a code snippet showing how to batch the creation of multiple Contact entities and POST them to SAP Netweaver Gateway. The code is part of a simple applications which displays Contacts retrieved from a Gateway OData call in a Table Control. The application has a button ‘Batch Save’, when the button is pressed the function below is called, on completion of the $Batch operation the Table Control shows the new Contact Entities.  The code also shows how easy it is to deep insert a second entity (CREATE_DEEP_ENTITY), Contact_Status represents a separate Entity which has a many to one relationship with the Contact entity.

Here is the HTTP Request, multiple operations wrapped up in a single Multipart MIME message.

And the results of the Gateway callback.
