ACH Picking up Reversed Checks?

We are seeing in our system that the Advice Register and Direct Deposit file (DDP001 and DDP004) are creating ACH data for reversed paychecks in certain circumstances.

The scenario would be reproduced by:

• Generating a confirmed paycheck with paycheck option Check & Advice - where the employee has set up part of their check to go to a bank account and part of it as a physical check
• Reverse the confirmed paycheck
• Run the DDP001 or DDP004 for the pay end date the original check was created

When this occurs the Advice portion of the paycheck remains on the DDP001 and DDP004 for bank transmission. When creating this scenario for a check that is paycheck option Advice (where 100% of the check is assigned to a direct deposit account) the check is properly removed from the DDP001 and DDP004 files.
