The dispute reason is what Lowe's will read when the dispute is submitted. By default, the dispute reason will default to be "Please review the attached documents". However, if you would like to create a new default message, you can do so by editing the Dispute Reason field found on the Dispute Default Settings page. This can be customized per code type.

Additionally, you can set the Dispute Reason Type per code. The Dispute Reason Types are unique to Lowe's and are based on different codes.

Once you make the desired changes, be sure to hit the "Save Changes" button. This will go ahead and update the dispute reason across all deductions that have not been disputed.
