Locking from OData URI

Hi Folks,

My requirement:

To Lock the document number from OData URI.

Locking concept is common everywhere. I already applied enqueue/dequeue mechanism in my back end logic and the document number is getting locked in the backend and as well as from oData URI, but here once I got the response from the OData URI, the lock is getting released for my document number where I did not applied the dequeue logic for this.

Questions:

1) Y the Lock is getting released?

2) is there anything related to eTag concept for this Lock Mechanism.

3) when I execute the OData URI, the lock should not be released, as I did not write the dequeue Logic, any suggestions?

4) From the back end its working as expected.

Please guide me and provide your inputs from gateway point of view.

Thanks & Regards,
