Troubleshooting Ongoing Errors

This section assumes that successful tests have been created and run before the error occurred.

In general, you should always check for the following sources of errors:

Incorrect connection

The Data Validation Option folder is open in the Designer, Workflow Manager, or Repository Manager

The following table describes common ongoing errors:

Error	Possible Cause and Solution
Installation or run errors	Verify that the Data Validation Option folder is closed in the Designer, Workflow Manager and Repository Manager. Verify that the PowerCenter environment is functioning correctly, for example, services are running and the repository is up. If the error occurred right after you created an expression either in a test editor dialog box or as a WHERE clause, check the syntax. Open the session log and verify that the PowerCenter connections are correct.
No results	Verify that there is data in the data set you are analyzing. Tables should have records. Filters or joins should not result in an empty set.
Inability to generate reports	Verify that you have read and write permissions on the Data Validation Option installation directory and subdirectories.
Inability to copy folders	Verify that the repository, data sources, and folders that contain the data sources have identical names in the source and the target workspaces. Object names in Data Validation Option are case sensitive. Verify that all data sources associated with the objects to copy exist in the target workspace in the same location and that the names match.
