Pickware WMS
Drop-shipping items are not listed in the Picking app of Pickware WMS, as the dropshipping is handled by the dropshipper.
Product Sets
A dropshipping e-mail address can be stored for sub-items independently of the product set item. This allows the dropshipper to be informed only about the sub-items, independent of the ordered virtual product set item, if this is desired.
Custom Products
The plugin from Shopware is compatible from version 1.2.6 to the extent that all information on the Custom Products items is listed in the dropshipping e-mail.
