Handling of Draft documents using ODATA

Fiori elements support Draft documents. For example, you can create a draft product, then update it in various stages (the draft gets updated/merged in backend - o data supports it). This is done in SAP UI5 library which has a draftcontroller. I wanted to do the same thing using JAVA - calling the POST/MERGE on same o-data entities (and its associations).

Is there any existing library which I can use for this in Java? O-lingo doesn't really help much here - but any suggestions are welcome.

    Hi Vivek,

    I'm not sure if there is a difference in Java, the ODATA created for draft should handle everything.

    When Calling the OData, there is no difference between a normal OData and a Draft OData.

    Create Method of OData would create an entry in Draft.

    Update Method of OData would Update the Draft.

    Basically, all the Operations are based on draft table ( except Read, Read considers both Draft and Active Table ).

    Once you finish all the changes to your data, then we move it to Active Table by calling a function Import called Activation.

    Now the next time when you want to edit an existing entry( from Active Table), you call the EDIT Function Import. This will create a copy of the data in Draft Table and once you finish all your changes, its again moved to Active table using Activation Function Import.

    Hope this was your question.
