Availability is the normalized ratio between the Allocation attribute and the Available To Sell (ATS) attribute of a product inventory record. Special rules apply for variation products, product sets, and potentially product bundles. Availability is the same for all sites that share an Inventory list, so it's basically a site-specific value.
Availability:
Example: Standard Product and Bundled Products Within an Inventory List
Allocation(p: 50)ATS(p: 10)
Availability(p: 10 / 50 = 0.20)
If the number of online variations is zero, then the availability of the base product is zero.
Otherwise, the availability of a base product is equal to the sum of the availability of each variation product divided by the total number of variation products. Availability is calculated using the following formula:
Availability(mp) =
SUM(Availability(vpX)) / X)
Where:
mp is a base product
vpX are online variantion products of the base product
X is the number of online variation products
Example: Base Product Within an Inventory List
Variation product 1
Allocation: 50ATS: 10
Availability: 0.20
Variation product 2
Allocation: 100ATS: 10
Availability: 0.10
Base Product
Availability: (0.20 + 0.10) / 2 = 0.15
A product bundle’s availability is the availability of its least available product, because products in a bundle can't be purchased separately. Availability is calculated using the following formula:
Availability(bp) =
MIN(Availability(cpX))
A product set’s availability is the availability of its most available product, because products are purchased individually, but are promoted through a set. So customers can purchase any item in a set that’s still available. Availability is calculated using the following formula:
Availability(sp) =
MAX(Availability(cpX))
Where
sp is a product set
cpX are online products in the set
Example: Product Set Within an Inventory List
Product 1 in set
Allocation: 50ATS: 10
Availability: 0.20
Product 2 in set
Allocation: 100ATS: 10
Availability: 0.10
Product set
Availability: MAX(0.20, 0.10) = 0.20
