CHAPTER 14

Viewing and Debugging Analytic Models

This chapter provides an overview of the Analytic Model Viewer and discusses how to:

• View analytic model properties.

• Use Analytic Model Viewer alongside PeopleSoft Application Designer.

• Use the application log fence to provide additional debugging information.

Understanding the Analytic Model Viewer

The Analytic Model Viewer is a debugging tool with which you can view intermediate results from

calculations and modify data when testing c alculations. This tool is provided in the runtime environment

through the PeopleSoft Pure Internet Architecture. Using the Analytic Model Viewer, you can view metadata

(such as virtual data cubes) that may not appear to the end user, and edit analytic model data to see how

your results would then change.

Even though you create analytic model definitions in PeopleSoft Application Designer, you need to view

an analytic instance of the analytic model during runtime to determine whether the analytic calculation

engine is performing its calculations as intended. Simply viewing an analytic instance within the application

during runtime is not sufficient, because some parts and data of the analytic m odel may not be visible to end

users. Using the Analytic Model Viewer you can view, analyze, and debug all c ube collections in the model.

The Analytic Model Viewer operates during runtime because it depends on the analytic calculation engine

(for calculation) and the analytic server (for data transformation). In the Analytic Model Viewer, you view

a specific analytic instance of the a nalytic model.

Although you can modify data from within the Analytic Model Viewer, you cannot change metadata, including

rules, from this environment. Conversely, from within the analytic model in PeopleSoft Application Designer,

you can change metadata but cannot change the data itself. The ideal solution is to simultaneously view the

design time analytic model, in PeopleSoft Application Designer, and the runtime analytic model, in the

Analytic Model Viewer. This arrangement enables you to compare calculation results, and to change either

data or metadata, based upon your needs.

After you load an analytic instance for u se in the Analytic Model Viewer, closing the viewer does not

automatically unload the analytic instance. You must do that manually from the Analytic Instance Load/Unload

page.

Note. You c an view causes, effects, and inputs in both PeopleSoft Application Designer and the Analytic

Model Viewer. PeopleSoft Application Designer displays the causes , effects, and inputs of data cubes and cube

collections. The Analytic Model Viewer displays not only causes, effects, inputs, but also displays overrides

(which are determined during runtime), thus providing a more detailed display of causes, effects, and inputs.
