Webi - Cannot execute empty query. (QTJ 00521) (WIS 00000)

Hi all,

There is a webi report tht has 4 Data Providers, which works perfectly fine,

When we added couple more Data Providers to the webi report , made our changes and deleted  the first 4 Data providers, as they are no longer needed for my report, when we save and refresh the report it throws the below error.
Cannot execute empty query. (QTJ 00521) (WIS 00000)
We changed the datasource to be pointed to the same BICS connection, it goes to the query panel and still gives the same error when you "Run query", we get the same error
We are in BO 4.0 SP 7, Any work arounds will be helpful.
