Odata Service Creation Using SEGW Transaction

Hi All,

I am trying to create an Odata service using one RFC that takes three input parameters and returns one structure as output parameter.

When I am trying to do mapping of Get Entity Set it is saying that key variable does not have output mapping. But my key variable is input parameter so I am unable to change the mapping direction of key variable.

Please some body suggest how to change the mapping direction of mandatory import parameters in get entity set query.

With Regards
