Then Go to start menu Programs IBM Cognos 10 Transformer IBM Cognos Transformer. Click on Create New Modelgive your model name select the datasource type as package (as we are using the FM Model as our data source and hence the published package has to be selected) Next Other data sources can be seen in the dropdown viz.. Already created reports, Packages(FM Model), .iqd files, excel files, .csv files , Flat files etc select the particular package by clicking on Browse and locate your package from the Public folders/ My folders tab click next change the Query name as you requirein the source window expand the presentation layer to view the DIM & FACT tables Step 1: Select each DIM query subject (DIM Table) and each FACT query subject (FACT table) INDIVIDUALLY (Do not select all the tables at once) and click Add you can select the DIM completely for all columns or expand the DIM and select only the required columns.
