Hi Dom,
it's been a while since I customized these topics, but if I remember correctly, SAP Standard should behave the following:
- WPMA (POS-Download): article requires a sales price (VKP0 or VKA0) to be sent out
- Assortment List: article without sales price can be sent out
[I even know some customers which implemted checks in Assortment List, so that articles without sales prices are not sent to POS]
I think, you could test that quite easily.
Regards
Tobias
