Database changes for Commerce inventory service
This document describes changes done to the database schema for the inventory service used when extracting inventory data directly from the EPiServer Commerce database. Refer to Inventory requests for information on how to access warehouse inventory information.
Accessing inventory information
Direct database access is usually not a recommended practice. The database schema is considered an internal artifact of the system and database schema changes may occur at any release without affecting the semantic versioning scheme. This means that a breaking change such as changing tables or table names in the database schema will not result in a major version update of EPiServer Commerce.
Database schema changes
The modifications to the databse schema involves migration of information from the old WarehouseInventory table to the new InventoryService table. If you have reporting running against the old WarehouseInventory table, this table will not receive any new or updated information, but the existing information will remain.
Below is an overview of the two tables.
When migrating data between the systems, the script below will be executed.
insert into [dbo].[InventoryService]
cast(case wi.[InventoryStatus] when 1 then 1 else 0 end as bit) as [IsTracked],
wi.[InStockQuantity] - wi.[ReservedQuantity] as [PurchaseAvailableQuantity],
wi.[PreorderQuantity] as [PreorderAvailableQuantity],
wi.[BackorderQuantity] as [BackorderAvailableQuantity],
0 as [PurchaseRequestedQuantity],
0 as [PreorderRequestedQuantity],
0 as [BackorderRequestedQuantity],
ce.[StartDate] as [PurchaseAvailableDate],
when wi.[AllowPreorder] = 1 and wi.[PreorderAvailabilityDate] < ce.[StartDate] then wi.[PreorderAvailabilityDate]
end as [PreorderAvailableUtc],
wi.[BackorderAvailabilityDate] as [BackorderAvailableUtc],
wi.[ReservedQuantity] as [AdditionalQuantity],
from [dbo].[WarehouseInventory] wi
join [dbo].[CatalogEntry] ce on wi.[ApplicationId] = ce.[ApplicationId] and wi.[CatalogEntryCode] = ce.[Code]
