[Blog bot]

==============


Actually, when you set up alternative item with “Nothing in inventory” and create sales order line, system will check the total physical available of ALL site and warehouses. If there is not enough stock, AX will change to the alternative item.
Sometimes, this is confused when you turn on the “Auto reservation” functionality. Because the reservation will only work at warehouse level, not site level. Therefore, if you have enough stock in all sites, system will not replace the item. But it doesn’t reserve against the other site, and you always have something to be available for checking of “Nothing in inventory” functionality.
Here is an example:
Scenario
Sample data
Expected Results
Open item master file, select item number 1501
- Use alternative = “Nothing in stock”
- Alternative item number = “1509”  
Check the inventory on-hand of item 1501, make necessary quantity adjustment to make sure the on-hand quantity (available physical) is
- Site 1, warehouse 11 = 10
- Site 2, warehouse 21 = 294
- Site 3 = 0  
Create a new sales order line
- Item id = 1501
- Site = 2
- Warehouse = 21
- Quantity = 304
- Reservation = Automatic
AX to save the sales order line without replacing the item with alternative item.
Create a new sales order line
- Item id = 1501
- Site = 2
- Warehouse = 21
- Quantity = 11
- Reservation = Automatic
System will change the item id from 1501 to 1509
