Introduction (0:00)
A basic introduction to the content of the presentation.
Why stock movements (0:45)
With stock movements, it is possible to register the amount and flow of stock. This is useful if you do not want to sell more products than you have in stock, to track the exact position of the current stock, which is useful for order picking.
Note: Stock changes also have an impact on finance if the stock value is tracked.
Positive and negative stock movement (3:57)
The current amount of stock in the warehouse is the sum of all stock movements. A positive stock movement is a stock movement which adds products to the stock, a negative stock movement decreases the amount of stock. There are several reasons for positive stock movements: Purchase, Returns, Movement, Manual correction. A negative stock movement exists because of either a sale, a movement or a manual correction.
Tallying (7:00)
It is important to know that every negative stock movement should have a positive counterpart. When 1 bike is sold (-1) there should have been at least 1 bike added earlier to the stock (+1).
Tallying is the concept of countering every negative stock movement with a positive one.
Moving stock (10:35)
When moving stock, a stock change of type ‘movement’ is created. Every negative stock change has a ‘corresponding positive stock change’ as its counterpart.
This way you can justify removing stock from one location, as it is added at another location with the “corresponding positive stock change” and the total amount f stock did not change.
Inventory corrections (NL: voorraadcorrectie) (25:38)
Inventory corrections help users to create multiple stock movements and group them together. Be aware that the screens of inventory corrections are somewhat similar to stock movements. There are several types:
- Movement (by choosing location A and location B with the amount, the system creates every underlying stock movement automatically).
- Mutation (This is for adding or removing stock at one location).
- Revaluation (this can be used when a wrong purchase value is registered. For a specific amount of products, a revaluation corrects the value).
- Product stock batch change (KB839), this type is not covered by this video.
Reservations (33:20)
Reservations are needed to prevent double selling a product. When a product is sold, a reservation is made. This means the reserved product can not be sold again, despite the fact that it is in stock. A reservation is always linked to a positive stock movement (tally) that has products left. This way, the application knows that the products in that specific stock movement are reserved.
