A price only concerns the customers of the group (inter-site customers).
In that case, a price setup with an identical code must be created in both modules (Purchasing and Sales) in order to make sure that the discounts and the charges are consistent. It implies that the price list structure of the inter-site supplier is the same as the sales price list structure of the company representing the supplier.
Entering the prices is only carried out on the Sales side. The Group purchasing price lists will then point to the sales price lists.
