Error in using key predicates

Hi all,

When executing the service URL with key predicates i am getting an error raised by exception /IWBEP/CX_MGW_TECH_EXCEPTION (message Internal error occurred, contact your system.).

The Associations, Referential constraints and Navigation properties have been maintained correctly.

The key predicates being passed are:

Airlineid='AA',Connectid='0017',Flightdate=datetime'2013-09-04T00:00:00'

The complete URL looks like:

http://<host>:<port>/sap/opu/odata/SAP/FLIGHTLISTDCR/FlightLists(Airlineid='AA',Connectid='0017',Flightdate=datetime'2013-09-04T00:00:00')/FlightDetail where FlightLists is the name of the Entity set and FlightDetail is the name of the Navigation property. Without the key predicates the entity set  returns the desired result.

The Error log message is vague and is as follows:

Internal error occurred, contact your system administrator.

Shall be grateful for any hints which could help me resolve this issue.
