How to shorten discount description sent from Order Management to AR

Summary:

We have many discounts that are based on Matrix Rules, and when those discounts are added to an order line, we see descriptions that might look something like this:

Freight-Delivery AUG2025 Discount rule applied because Item Number=null Freight Item Category: Blackberry B In Hierarchy Blackberry B ShipTo Site Number=1000968 Warehouse=1001DA0001 Ship Mode Of Transport=null RequestArrivalDate:01-01-1960<>2025-07-06 08:00:00.0

The rules of pricing aren't going to change and we have what we have.

When this gets sent to AR, we are getting errors because that explanation is more than 240 characters, which is the length of the invoice line description field.
