SAP HANA XSODATA service dateformat problem

Hi all,

i have a problem about xsodata service on calculation view (in calculation there's a single input parameter called P_NPLDA , a date type).

When i run this link on browser :

http://host:port/Project_DM/services/Test/TEST_INPUT_PARAMETERS.xsodata/InputParams(P_NPLDA='2014-04-14')/Results

the system gets the following error :

<messagexml:lang="en-US">Illegal query syntax.</message>

What does is it wrong in this url?

Thanks in advance.

Regards.

Dario.
