Could not able to pass parameters in URL

Hi,

I developed one custom RFC instead of using BAPI_ADDRESSEMP_GETLIST, as i have many custom fields in PA0006, i created this custom RFC.

After that I  used SEGW ,gateway service builder to import the RFC and created entity and entity set.

can you just help me in how to do mapping in GET_ENTITYSET and GET_ENTITY, what values to be passed and mapped and at the same time how to check the values in output URL like $filter, $select.

NoTE: In my Custom RFC importing parameter pernr is mandatory.
