Hello Arun,
in your service definition you named the entity for the parameters "Input", in the URL you wrote "Inputs". Remove the "s" in your URL. In addition the column names CARRID and CONNID do not have to be enclosed in quotes.
You should also add "/Results" to your URL to get the results back. "Results" is the automatically generated navigation attribute to get the results.
So your URL should look like .../AB_Service.xsodata/Input(CARRID='AA', CONNID='0017')/Results
Best Regards,
Florian
