If the Inventory module has been activated, it is possible to create a load stock movement in two different ways:
With the registration of an Inventory adjustment movement
With the issue of a purchase stock receipt or the registration of a purchase invoice
In the first case, it is possible to post the Inventory additions without processing purchase documents by creating adjustment entries and booking them. To do this, you need to start the Inventory adjustments application under the Inventory > Adjustments and transfers menu item.
In the second case, however, the loading is carried out when the purchase receipt is issued, or in the case of registration of a purchase invoice in which the supplier and the products belong respectively to a supplier group and to a product group that's linked to Inventory withdrawal.
