Every Stock Item which is found in the system with aDate Availabl f 01-01-00 indeed must be present in the Warehouse on the Location the system indicated. If the Availability Date of a Stock Item is not equal to 01-01-00, the Stock Item will not be on Stock until that Date.
Nb.: A.o. a Transform Order can generate StockItems per a certain Date. For after all from a Transform Order per entered Finished Date an already fixed Output will become available.
The exact Cost Price is known of the Stock Item, as well as the exact Weight (also for other Stock Units than KG).
In general the StockItems which are not yet available will be ignored by the system, they are only used by Functions which have been created specifically to execute Operations with StockItems not yet existing.
This way a Stock Item which will be available per next
Week, will not count today with respect to the Technical Stock, for the Technical Stock indicates what is actually on Stock and this Item will not be on Stock until next Week. As this Item is not counted for the Technical Stock, this Stock Item cannot be delivered, and correctly, for the Item is not on Stock. Should this Item be delivered, a Picklist would be created which indicates that an Item is to be picked which is not on Stock at all (so cannot be picked).
A typical example of Functions that do take the StockItems not yet existing into account, are the Transform Orders. It is possible to transform a not yet existing Stock Item per a certain Date. The Date on which this Item is to be transformed can never be prior to the Date on which this Item is available.
Suppose a Transform Order has been added which indicates that from a 10.000 Metre Bar a Piece of 6.000 Metre is to be sawed off. The Order will have been completed in 3 days. So in 3 days there will be a Piece of 6.000 Metres and a Piece of 4.000 Metres on Stock. The 6.000 Metre Piece will immediately have been reserved when executing the Transform Order for the Function that generated this order (for you do not just enter an Order to saw, this is done as there is a Demand for a 6.000 Metre Bar). The 4.000 Metre Piece, which is on Stock in 3 days time, will however, not have been reserved and can be used for new Transform Orders.
If there is a Demand for a Bar of 3.500 Metres in 4 days, a Transform Order could be generated which uses the 4.000 Metre Bar (which will be on Stock in 3 days) as input. When generating this Order the 4.000 Metre Bar will be reserved immediately so that it cannot be used again by another application.
Nb.: Note that the second Transform Order will result in yet two new StockItems (a 3.500 Metre Bar and a 0.500 Metre Bar).
