Couldn't find SAP standard query when I open from BEx Query Designer

Hi Guys,

              I try to open SAP Standard Query 0DF_MC01_Q0003 from BEx Query Designer.

But Couldn't find it.

is there a way to activate them or its available by default..?

if I want show a BI Report in Portal.. do I have to create it in BEx Web Application Designer and then publish in portal as BI iView..?

Thanks

Sam
