I am new to cognos and I am having a problem adding a datasource to transformer which maintains the structure of the tables which have been published in the datasource. I have a fact table with several separate lookup tables. When I add them to the package all appears to be Ok. When I import them in transformer the table structure has disappeared to be replaces by a single table/list of attributes. How can I avoid this from happening without having to create a separate package for each table?
