Viewing and Exporting Verification Results

After the verification tasks on the source and the target are executed, you can view and export the verification results of tables by batch. A batch is a group of verification tasks executed on the same day. If a task is executed multiple times on a single day, only the latest verification results are included in the statistics. Its previous results will be overwritten.

Prerequisites
