Review all fields and rows in the batch looking for invalid characters.
To export the batch, right-click in the Member Contributions Notifications grid and select Save Grid.
Once you find the data causing the error, close the batch and the Super Clearing Batches window.
Fix the data (e.g. fix the employee's name on the employee record).
Return to Payroll, Transactions, End of Period, Super Clearing Batches.
Select the batch.
Click Validate to ensure that after the fix the data is valid.
Then, click Submit.
