I am trying to generate an Assortment List IDOC for a wholesale customer. I am able to create the assortment via WSOA1, and list articles via WSM3, but I am not able to generate the Assortment list via WDBx_HPR as there is no site. These WDBx_HPR transactions seem to require that the customer is a retail customer with a site. Since there is no site associated with the wholesale customer, is there a different transaction that can be used to generate the Assortment List IDOC?
