save failed, status: error message: Import Failed: A Valid Name Must Be Provided for Datashape savin

Hi,

I created a service for displaying current date time "SELECT substring(convert(varchar(20), GetDate(), 9), 13, 5) + ' ' +substring(convert(varchar(30), GetDate(), 9), 25, 2)"

I am getting output correctly on saving but I am not able to create data shape, On saving I am getting an error "save failed, status: error message: Import Failed: A Valid Name Must Be Provided".

I checked the application log but it says the same error as Invalid name.

How do I resolve this issue.

Please provide some help.

Thanks,

V Shalini.
