How to delete avaible database objects in Framework

Good morning,

My Facts and Dimensions are changed from datasource.
Inside the attributes, identifiers etc. are the same.

I thought it would be easy to just change the SQL statement from the query subject:
Like this: Adding the new datasource and change the select * statement:

But somehow it still recognizes the old database, anyone know how i can easy change of database object so i dont need to build the framework again.
This is the error:

Thx in advance

I know that this a bit older post, but in case you didn’t figure this out: select query object that you need to modify then go to Tools>Update Objects and execute that command which validate and update your query objects according latest database DDL. Hope that helps…
