Hiding Layers in the Administration Tool for Ease of Use
Under the View menu, consider displaying only the repository layers that you are working on. Your eyes will thank you! Viewing all three repository layers at once reduces visibility to objects with long names, especially in the logical layer.
Creating Time-Series Metrics Using the Calculation Wizard
After creating your base metrics, try using the Calculation Wizard to automate the process of creating time-series metrics or comparison metrics such as: Change, Percent Change, Index, and Percent. The Wizard may save you many hours of time and frustration, especially if you have to create more than a handful of these metrics. In addition, the Wizard allows you to include customized logic to handle nulls in the base metrics. You may refer to the Oracle documentation for further detail.
