Not getting Mulltiple records from ODATA Service

Hi ,

I am not getting the  Multiple records  for a Gateway ODATA service.

For example:

http://123.XXXX/sap/opu/odata/sap/ZXXX_ORDARRY_SRV/ORDDETSet(Userid='XYZ',Type='11')?$format=json

The requirement : I need to get multiple orders data from  based on the User id 'XYZ'.

If I give the  URL as  '['http://123.XXXX/sap/opu/odata/sap/ZXXX_ORDARRY_SRV/ORDDETSet",
| http://123.XXXX/sap/opu/odata/sap/ZXXX_ORDARRY_SRV/ORDDETSet]

I will get the multiple orders.

 Entity set Mapping  is  referred to a Function module where the User ID is passed to Custom table and we are able to get the  Multiple values in the Tables Parameter.

But still the ODATA service returns the Single record.

Thanks,
Shreedhar
