Issues while using PUT in Sapui5 using odata services..

Hi Experts,

I'm using Odata services, Everything is working fine Except the moment when I try updating or using "PUT" operation.

In the gateway side while using the same URL, I been able to update it but the same is not happening through SAPui5,

I'm getting a 403 forbidden error, attaching a screen shot of the error.

I try reading other blogs, but it was not helpful...I can even post the codes also if anybody want it.

Need help !

Regards,

Ashwin
