Default package definitions
Because an individual warehouse may use a different package definition to handle the item, a default, possibly different, package definition is also provided in the Item Data by Warehouse (whwmd2110s000) session.
You can choose to assign a default package definition by business partner and item. This definition is used for a supplier who packages the item in a way that differs from other suppliers. When you create a purchase order for this item from this supplier, the package definition defaults to the one defined for this business partner and item. This default can be overridden in the Items - Purchase Business Partner (tdipu0110m000) session, if required.
For sales orders, a mandatory package definition can be selected in the Items - Sales Business Partner (tdisa0510m000) session. You cannot replace a mandatory package definition with another package definition, and the package definition is always mandatory for outbound order lines.
The package definitions specified for sales and purchase business partners overrule the default package definitions specified in the Item - Warehousing (whwmd4500m000) session or the Item Data by Warehouse (whwmd2110s000) session.
