Currently, we have all customers setup to receive an order confirmation as soon as the order is saved. This is accomplished via VV12 and putting a value of '4' in the "Date/Time" field (Send immediately). However, I'd like to change that value to '1' for specfic customers, which means "send with periodically scheduled job'. My question is this. Is there an SAP delivery job / t-code that I can setup as a background job that runs every night, or must I write a custom ABAP program?
