Use BW BEX Query with Dashboard doesn´t work

Hello.

I'm tryiing to use a bw bex query into dashboard, but it tells that query doesn´t have the mark olap connection, when it's false, because the query has the mark Olap connection.

Here is the image where shown that query doesn't have the olap mark

But it really has the mark in query designer. (it's the same query in same environment)

Could someone help me please ?

Thanks.

Angel.
