The item availability check enables you to assess the following:
If a specific item is available
If a specific item is in a particular warehouse
If a specific item quantity is available
If a specific item is available for delivery on the required date
In addition, you can check:
The item quantity available on the requested delivery date
The earliest delivery date for the full quantity required in the sales order
A basic Available-to-Promise (ATP) report that provides additional information about item availability, such as the uncommitted stock and receipts available to satisfy potential customer orders. See Inventory Status Window.
The Item Availability Check window only appears when the quantity of an item required in a sales order is larger than the available quantity on the delivery date, minus the minimum level. The minimum level is defined on the item level or at the warehouse level (as defined in the Item Master Data window).
The quantity is calculated as follows:
Available = In Stock + Ordered – Committed from the current date to the requested delivery date.
If you update an existing sales order (instead of creating a new one), SAP Business One does not take into account the existing sales order values when calculating available quantity, as it does when you create a new sales order.
Example
A purchase order was created with a quantity of 10 items.
Sales order 1 was created with a quantity of 6 items.
Sales order 2 was created (this is a new sales order) with a quantity of 5 items, and the available quantity is calculated as 4 items.
If the quantity in sales order 1 is updated from 6 to 8 items the available quantity is calculated as 10 items.

Warehouse from which the item is ordered. |
The quantity that has been ordered by customers (sales orders), based on the following calculation: Quantity (as defined in the sales order) × Sales UoM (as defined in tab = IUoM.If units of measure are not defined for the item, this calculation is not displayed, and only the SUoM or IUoM appears. |
The delivery date (for the row) when the customer requires the ordered items. |
The quantity of an item that will be available for delivery on the Requested Due Date for the selected warehouse. If the Requested Due Date is beyond the item's lead time, then the Available Quantity is the requested quantity. SAP Business One determines the available quantity by checking that the amount in the Available Quantity field is greater than the following:
Note If a Delivery Date is not entered in the sales order the current system date is used. End of the note. |
The earliest date on which the requested stock will be available according to ATP logic (see Inventory Status Window (Normal and ATP Layout)). If the Earliest Availability date is beyond the lead time, a message appears. Lead time (LT) is the planned time interval between the shipping of a delivery in the ship-from location and the expected time of arrival at the location receiving the delivery (customer or ship-to location). The calculation of lead time is done as follows: Current date + lead time (as defined in tab) + holidays (as defined in tab).Example The example below describes how to calculate the earliest available date for an item. Lead Time − When calculating the Earliest Availability date for an item: The current date is Thursday May 22, 2008. The lead time defined in the Item Master Data window is 3 days. The weekend is defined as Saturday and Sunday in the Company Details window. In addition, May 27, 2008 is defined as a holiday. The earliest available date is calculated as Wednesday May 28, 2008.
