You can release a purge batch only if every project in the batch has passed validation. All projects in the batch that do not pass validation must be corrected or removed from the batch.

Projects that have passed validation have a validation status of Valid. Projects that do not pass validation have a status of Invalid. You can view the validation status of the projects in the Purge Batch Details window or the Purge Validation Report, which lists invalid projects and the reasons that the project failed validation.

To identify errors in a purge batch:

1. Navigate to the Purge Batches window.

2. In the Batch Name field, query the purge batch name and choose Edit Details. The Purge Batch Details window opens.

3. In the Purge Batch Details window, select a project that failed validation.

   For more information about the selected projects, use the Purge Batch Details Window (see: Step Two: Review and Refine the List).

4. Choose the Errors button to display the errors in the Validation Errors window. You can also view the errors in the Purge Validation Report.

5. Correct the errors. You can either remove the problem project from the purge batch (Choose Delete Record from the Edit menu) or correct the condition in the project that is causing the error.

   For more information about the conditions that must be met before a project can be purged, see: Prerequisites for Purging Projects.

6. Run the validation process again (see: Validate the Projects in a Purge Batch.)
