Saving a query in Bex Portfolio

Hi all,

I am new to this portal thing, But i need some advice from you.

I am running a query from BW(writing a query in query designer and execute on web)which publishes it on portal. When i see the query, i see i save as button at the top and so i went there and i saw that i can save the query to bex portfolio ( which actually is my primary aim to get the query in left navigation panel of the page of BI or Bex). When i try to save under the Bex Portfolio its aske me for description so I put in some logical name and hit ok. But then it gives me two errors

"the technical name must be between 0-30 chars and 1-9 numbers" which I have it in the same format

"no valid element selected".

I am not getting what does it mean by valid element not selected.?

Can some one help me how can i save the query in BEX portfolio.

If any one has a related document which helps with issues about this whole query execution on portal I will highly appreciate it.

Thanks a lot in advance,
