Hi All,
I am attempting to use the SAP GWM Excel plugin to work with oData services exposed through HANA. I am able to GET data, DELETE data and even create new records using POST. However updating existing records fails. I consistently get the error message "Invalid HTTP method. Only GET, POST, PUT, DEL methods are allowed.".
After scratching my head and using Fiddler, I figured out that the Excel plugin is always using the "MERGE" operation as opposed to "PUT" for updating existing records. I guess that makes sense as it is only modifying some properties and not necessarily all. I tried to force all the fields to be changed, but still only MERGE operation is being used.
So I guess the question is, will the Excel add-in support oData services from HANA? If not, are there other alternatives to allow end users to use Excel as a front end to update data directly in HANA? Does HANA xsodata services framework have any roadmap to support MERGE operations?
I have also cross posted this in the "SAP Microsoft Interoperability" space.
thanks,
Nitin
