Hello Friends,

I have created a ODATA SERVICES based on easy Query.But whenI run the URL for metadata. It gives runtime error because it needs to pass Input parameter.

I dont know how to pass Input parameter in odata created based on Query. My Bex Query has 1 Input variable which needs to be passed at run time.

Please help to resolve this Issue.
