datasource - Problem with query as a new data source in Cognos PowerPlay -

-

normally can add query new data source in cognos powerplay (i'm running powerplay version 7.3), when try cannot select queries access database. dropdown menu shows existing queries in database empty. when add table new data source works fine, , tables shown in dropdown.

previously worked fine queries too, won't work. know if it's cognos error or system configuration on pc causes error appear?

i didn't find answers question, did come workaround solution problem.

the trick create new ms access database (fx called workarounddatabase) , create query has same name original query in mother database (the name of query wanted add data source in first place).

then first create new data source links query in workarounddatabase. secondly right-click on data source , change path mother database. since names of queries same data source links query in mother database (which wanted, byt couldn't directly because of cognos powerplay bug).

this procedure works fine in cognos powerplay, though doesn't give explanations on original error in cognos powerplay.
