Date date item creation in report studio

[umareddy0706]

Hello everyone,

I have created date data item, using with this expression. data item name:

_last_of_month ( 2014-11-30 12:10:10.000 )

but I have given this data item reference to another data item. It is not recognized.

Another data item expression :

case
when ([Presentation View].[Roadmap Comments (many to 1)].[Line Item STC Comment Date Modified] is null ) then [date]
else ([Presentation View].[Roadmap Comments (many to 1)].[Line Item STC Comment Date Modified])
end

which I have created the date data item it is not working as I expected in my report. ( where ever the date is null .. it is not applied)

Can you please guide me.

thanks in advance
