Do you create products that you think you will sell more than once? Make it an item. In MKG, this can be done very easily from an existing sales quote or sales order. It saves a lot of input work when creating the next one, especially if you have an associated calculation that you can use as a bill of materials.

The advantage of a picklist is the control and oversight over the inventory situation. By not issuing material lines directly, an additional step is necessary, where it is checked whether the stock is actually available. As a result, a picklist must be reported back.
