Metadata Export: When you export a Warehouse Builder project or specific objects using the Metadata Export Utility, Warehouse Builder records the details of the export in a log file. You can specify the name and location of this log file from the Metadata Export dialog box.

Metadata Import Using the Transfer Wizard

If you are importing design metadata using the Warehouse Builder Transfer Wizard, then you can view the log file after the import is complete. Warehouse Builder displays the My Metadata Transfer dialog box.

Double-click a message in the Message column to display the detailed error message in a message editor window. To save the message to your local system, select Code in the menu bar, then select Save as File.

Warehouse Builder saves the last validation messages for each previously validated objects. You can access these messages at any time by selecting the object from the console tree in the Project Explorer, select View from the menu bar, and then click Validation Messages.

You can store execution or deployment error and warning message logs on your local system by specifying a location for them. In the Project Explorer, select the project. Then from the Tools menu, select Preferences. In the Preferences dialog box, click the Logging option in the object tree to the left. In the list box on the right, you can set the log file path, file name and maximum file size. You can also select the types of logs you want to store.

You can view this log of deployment and error messages from the Warehouse Builder console by selecting View from the menu bar, and then Messages Log. This Message Log dialog box is read-only.

Runtime Audit Browser

If an error occurs while transforming or loading data, the audit routines report the errors into the runtime tables. You can easily access these error reports using the Runtime Audit Browser (RAB). The RAB provides detailed information about past deployments and executions. These reports are generated from data stored in the runtime repositories. Click the Execution tab in the Execution reports to view error messages and audit details.
