Explanation
Box 1: Ordered reserved
On-hand inventory available for all transactions except for sales orders.
Query your on-hand inventory
To check the availability of inventory, go to Inventory management > Inquiries and reports > On-hand list.
The On-hand list page is automatically updated when transactions are made in inventory. Those transactions might be forecasted, physical, or financial transactions.
For each matching item, the On-hand grid provides the following columns of inventory information.
* Ordered reserved - The total quantity that is reserved on ordered receipts. The value in this field represents the total quantity of items in outbound transactions that have a status of Ordered reserved. Items that are reserved as ordered aren't physically available in inventory. Therefore, they can't be directly picked and delivered.
* Etc.
Box 2: Inventory blocking
Automatic hold on inbound purchase order inventory.
Inventory blocking is part of the quality inspection process in Supply Chain Management. You can use inventory blocking to prevent items from being processed or consumed.
You can block inventory items in the following ways:
Manually
By creating a quality order
By using a process that generates a quality order
By using inventory status blocking
Box 3: Inventory status
Damaged on-hand inventory that can be transferred from a mobile device, leaving the undamaged inventory available.
Set up and use inventory statuses
You can use inventory statuses to categorize inventory. You can then initiate appropriate actions, such as replenishment or put-away work.
Here are some examples of ways that you can use inventory statuses:
Create inventory statuses for on-hand inventory, inbound transactions, and outbound transactions.
Specify a default inventory status for warehouse transactions.
Change an inventory status for items before arrival, during arrival, or when the items are put away during inventory movement.
Use an inventory status to price items that are returned and to plan item coverage during master planning.
Incorrect:
* Quality Order
The Quality management for warehouse processes feature lets you integrate item sampling controls into the warehouse receiving process by using warehouse management processes (WMS). Warehouse work can be automatically generated to move inventory to the quality control location, based on a percentage or a fixed quantity, or based on every nth license plate. After a quality order has been completed, work can be automatically generated to move inventory to the next location in the process, depending on the quality results.
The Quality management for warehouse processes feature extends the capabilities of the basic quality management feature. It provides the option to create quality orders for the inventory that is sent to the quality control location, although quality orders aren't always required. Therefore, it allows for a lightweight quality control process that is based on warehouse work.
* Nonconformance
A nonconformance describes an item that has a quality problem. The nonconformance process lets you create a nonconformance order that describes a quantity of nonconforming material, the problem source, the problem type, and explanatory notes.

Explanation
Box 1: Product
Current environment. Items
Product numbering
All items are numbered by using a smart numbering format: [Product SKU+Size+Color+Style]. For reporting, items are queried for sales and inventory reports by using the first six digits of the item number or until the first dash is encountered.
* A t-shirt could be 01001-S-Red for item 1001 in a size small with the color red.
* A single energy drink could be 02001-12oz or 02001-20oz for the different sizes that product 02001 is sold in.
Product attributes
* All clothing shares the same set of product attributes.
* Supplements may share the same Product SKU but can have different attributes for the different size, color, or style variations of the product.
* Product attributes that are unnecessary for an item should be excluded from the item.
Box 2: Product variant
Product masters and product variants
In an agile world, where products must be quickly adapted to customer requirements, product definitions specify a set of products instead of distinct products. In Supply Chain Management, those generic products are known as product masters. Product masters hold the definition and rules that specify how distinct products are described and behave in business processes. Based on these definitions, distinct products can be generated.
These distinct products are known as product variants.
A product master is associated with a product dimension group and a configuration technology to specify the business rules. The product dimensions (Color, Size, Style, and Configuration) are a specific set of attributes that can be used throughout the application to define and track specific behaviors of the related products.
These dimensions also help users search for and identify the products.
