PowerCubes provide secure and fast data access. Keep in mind that Cognos cubes are static and building a PowerCube is a repetitive process cubes may be refreshed every day, every month or even once a year. Main PowerPlay Transformer features: Leverages aggregate and fact tables Intergation of the query data into the model The models are defined by dimension structures and measures which can be easily customized No custom programming required Time periods are handled in a specific way which makes data delivery easy High flexibilty and portability PowerPlay cubes modeling and development process The application development process in Cognos PowerPlay Transformer usually contains the following steps: Gather business users requirements Create a Model Plan which will include design and data requirements for the model and decide on the cube distribution methodology Select measures Design and develop the PowerPlay model in Transformer Create PowerPlay cubes and distribute them to the end users Analyze and explore the cube data using PowerPlay A Transformer Model can be also created using a wizard with AutoDesign function or manually. We strongly recommend to avoid the AutoDesign function as in most cases it does not provide the results expected. PowerPlay Transformer application The default Cognos PowerPlay transformer window is composed of the following windows depicted on the the screenshots below.

Mezikasa Cognos namespace on the Custom Views tab left pane v all the levels and categories in the selected dimension, in the category viewer right pane You can access the main menu, toolbar buttons, and pop-up menus from any pane and use these controls to fine-tune your model.
The following table lists the available Inclusion settings and provides a description of each. You can remove them entirely, powerpoay you can hide them from specific user groups defined in your configured Cognos namespace. The status value is listed in the PowerCube Properties box. The files are created in the order specified in the list of paths.
Specifying A Segmenting Prompt For An Sap Bw Query Since prompts apply to all queries in the Cognos Transformer model but are maintained separately for each query, the specified values should be the same in all queries. Modeling Your Key Performance Page 57 Show Scope command checking measure allocation scope using to troubleshoot model design problems 9 signon creating a Cognos 8 signon 55 samples creating a data source signon 55 Cognos Transformer signon processing employee expenses.
You have tried to either generate categories or create PowerCubes when no data sources are set to be run as part of the process.
The expectations were small, but the results overwhelming. Page Parameter name Description The name of the data source. When Cognos Transformer is installed on Windows Vista, if you do not run Cognos Transformer as an administrator and you make changes to the cogtr.
Cognos Transformer is unable to locate columns for use in the AutoDesign process. Omit Categories Using Suppress The values for the descendants of a suppressed category are rolled up and retained in the ancestor category.
Set the Level of Detail for Dates Values for some measures in a model often apply to time periods that are not at the lowest level in the time dimension.
Signons list, and is not saved in the model. CubeName This is a mandatory value. Dimension property sheet, click OK. Cognos Products and Tools — TechyLib Page data souces performing test builds samples PowerCubes open slowly data source scope publishing to IBM Cognos Connection verifying and troubleshooting 44 routine maintenance tasks data source types samples changing 33 security Disable Rollup On Special Categories In the diagram, the children of the special category appear both in the main hierarchy and in the special category branch.
This allows the consolidated records to be written to the cube as specified. To define the metadata that will populate the Cognos Transformer cube, you must change the properties of each characteristic that you have selected for inclusion. Generating Categories from a Specified Data Source If your model is based on more than one data source, you may find it useful to generate categories from a specific source, such as the one that supplies your key structural data or the values for your time dimension, rather than from all the data sources.
The first is a time-based control file. Disadvantages of a Time-based Partitioned Cube Category handling, sorting enhancements, and support for external rollup make time-based partitioning a useful optimization technique for production environments.
Constraints In developing your partitioning strategy, consider the following constraints: Page Choose this option when you want to maintain the view operations applied in the user class views and use the IBM Cognos Series 7 user classes, or if you want to transition to an alternate security provider but need to maintain the IBM Cognos Series 7 user class objects to ensure the transition is carried out correctly.
Cognos Products and Tools If you then attempt to recreate the cube, Cognos Transformer will not allow the operation because the cube may already contain some of the data from the most recent increment. For example, the year is represented as A negative Appendix F.
Procedure Instead of deleting the entire cube from the group, you can create a dimension view that excludes the data associated with the category tranzformer want to remove. Check the location of the temporary files, as specified on the Directories tab of the Preferences property sheet; for example, Data Temporary Files dir1;dir2. Cognos Transformer Samples The Cognos Transformer installation includes sample data sources, models, and cubes.
Results You are now ready to create a model in Cognos Transformer. Either you have referred to a category set by an object name or object identifier that Cognos Transformer is unable to locate, or you have not referenced coggnos category set.
IBM Cognos Express 0 views 41 pages. In the Password box, type the password. The name in the model The Windows location of the data source. Page The following dimension map icons are used to indicate the type of dimension or level. These analysis and investigation skills were quickly recognized and are, probably, one of the main reaso ns for my long lasting relationship with WestLB and I consider it a big advantage compared with other candidates. Note the different column names and the use of zero for the date.
Omit Categories Using Cloak For example, suppose that your company maintains branches throughout the world. Page Transfofmer can set up drill through to a cube on a UNIX or Linux server by creating a temporary file in the Custom reports list and entering the path of the targeted drill-through file. If you have specific data that you do not want changed within the cube, you can use externally rolled up measures to maintain control over which values are stored and displayed.
When Marthe moved from Vancouver to Ottawa gkidethe report displays the historical data for and in Vancouver, and the new data for in Ottawa. Change the data definition for the column using the string-to-number function, save the. Page These default dimension views are created for every dimension, and are used to include or exclude entire dimensions from a PowerCube. This action was taken to avoid syntax errors in MDL.
