oDataModel v2 update (PUT) fails in batch

[pdominique]

Hi,

I'm using SAP UI5 1.44.11 and I have to disable batch mode to update my entities otherwise I get the following error:

The Data Services Request could not be understood due to malformed syntax

I replayed the batch request in the GW client and I noticed that the PUT keyword was not in upper case (i.e Put instead of PUT). When I modify the keyword manually in the GW client then the request works as expected.

I was going to disable batch globally in the manifest for my model when I noticed something:

"": {
	"dataSource": "mainService",
	"preload": true,
	"settings": {
			"defaultBindingMode": "TwoWay",
			"defaultUpdateMethod": "Put"
	}
},

I changed Put to PUT in the manifest and now everything works just fine. Maybe a check should be added somewhere.

Now this was really a bad situation. Many thanks for reporting this incident and the solution as well - we experienced the exact same issue. This should definitely be checked in the manifest.json and corrected automatically by the framework to uppercase PUT in requests.

This is a known issue and should be improved. See #4201

Hello @pdominique, @szebenyib,
Thank you for sharing this finding. I've created an internal incident DINC0398068. The status of the issue will be updated here in GitHub.

Hello,
To avoid spelling issue we deprecated the old sap.ui.model.odata.UpdateMethod enum keys Put and Merge in the current UI5 1.x codeline and replaced them by PUT and MERGE.
Additionally to that we map the deprecated enum keys Put and Merge in the sap.ui.model.odata.v2.ODataModel constructor to the corresponding values PUT and MERGE.
Best Regards,
Sven
