Applying a promo code to an existing order

[Craig Ambrose]

Hello,

Is there a service or, hopefully, some user interface in the Order Manager to apply a promotion code to an existing order? I see a mechanism to edit an order and to apply an adjustment with the type of adjustment (Discount, Donation, Promotion, etc.), a comment, and a dollar amount. This will create the proper OrderAdjustment DB entry. But it doesn't seem to use a promotion code and doesn't create a ProductPromoUse DB entry.

I would like for all the proper tables entries to be created as if the promotion was applied to the shopping cart and then the order submitted. We need this to keep our reporting consistent.

Thanks for your help
