multiple datasources in DSV creates error.

hi Friends

I'm using Two data sources.

i need to add table from these two data sources.

When i add table from first data source and  process the cube it works fine.

but when i add second data source table and process dimension it return error.

Errors in the high-level relational engine. The 'Test' secondary data source is not a relational data source, or does not use an OLE DB provider.

My using MYSQL datasource

i'm using  connectionstring;

server=172.16.10.13;database=asterisk;Allow Zero Datetime=True;Sql Server Mode=True;Persist Security Info=True;Convert Zero Datetime=True;password=**********;User Id=cron

server=172.16.10.13;database=test;Allow Zero Datetime=True;Sql Server Mode=True;Persist Security Info=True;Convert Zero Datetime=True;password=**********;User Id=cron...

kindly suggest something needful.
