I have seen few SCN posts regarding same issue but I didn't get solution.
I also read SAP Note 597326 but again no luck.
My scenario is : DataSource > DSO > InfoCube > Bex Query
I have modified DSO/Infocube (which is already transported to quality) with some new characteristics & also I have removed few characteristics.
While transporting, the infocube & BexQuery is getting transported without any error but DSO gives below error while transporting.
We are getting same error when we create new DSO (Not present in QA) in Dev & try to transport it to quality.
