Only those suppliers referenced at the Products-Suppliers level can be entered or selected.

1/Enter the associated code or click Select supplier-product using the Actions icon to select the code from the list of referenced products-suppliers.

The other data in the table cannot be entered.

2/ Below the table, enter the various fields relating to the management of this product-site for this supplier. In creation mode, fields inherit the setup defined at Product-Supplier level.

Once the fields have been entered, you can at a glance view the full list of the possible suppliers for this product-site: What is the priority level for each supplier? Which is the default supplier? Which is the default back-to-back order supplier? Is this a blocked supplier? A back-to-back order supplier?

In the supply plans and on document entry in the purchasing flows, the type of control performed on the referencing of the product-site with the supplier is dependent on the value of the ITMBPSFCY - Supplier-site referencing parameter (ACH chapter, REF group).
