Hi Chandan, OData 4.0 explicitly disallows this: Deep Insert is allowed, but not Deep Upsert or Deep Update:
11.4.3 Update an Entity (http://docs.oasis-open.org/odata/odata/v4.0/cos01/part1-protocol/odata-v4.0-cos01-part1-protocol.html#_Toc372793719) [...] The entity MUST NOT contain related entities as inline content. It MAY contain binding information for navigation properties. For single-valued navigation properties this replaces the relationship. For collection-valued navigation properties this adds to the relationship. [...] The OData 2.0 specification is less explicit, but we shouldn't add things to 2.0 that we know not to be allowed in 4.0 Regards! --Ralf -----Original Message----- From: Amend, Christian [mailto:christian.am...@sap.com] Sent: Thursday, 16.

The core library already provides the processor with the data. So it is up to the application to make the update in their database or however they store their data. So in my opinion the JPA Processor has to decide here if this should be supported or not. Or if there is a way to leave this to an application to decide. Also the question is what status code to give as a response. Best Regards, Christian -----Original Message----- From: Klevenz, Stephan [mailto:stephan.klev...@sap.com] Sent: Donnerstag, 16.

In my opinion OData does not disallow this use case. Because of the customer already exists the return code has to be 204 [1]. < Stephan [1] http://www.odata.org/documentation/odata-v2-documentation/operations/#26_Up dating_Entries On 16.01.14 14:08, "V.A, Chandan" <chandan....@sap.com> wrote: >Hello All, >I have couple of doubts with respect to Deep insert. > > >1) Can we perform an HTTP Put on an Entity with inline entries that >are yet to be created? >Say I have a Customer entity "A" already created.
