How do we create a new Child node without updating or creating the root node in SAP Gateway Client?

345 Views

Hi,

I have a parent entity and a child entity in my oData Service that was created using CDS views.

The scenario is to be able to just add a new child node to an existing root node. How could we do this in the SAP Gateway Client.

I tried the POST operation on the Child entity Set by providing the Parent key and other field values but I got an error message 'Invalid method invocation: 'CREATE' method is called on the non-root entity 'ZXXXXXXX''.

I tried calling PUT at root entity level and tried to pass child node values but that failed too.

So how would we deal with this scenario? Please guide.

Best Regards,

Raju
