Understanding the Product structure:

In this post, I would like to share some Product information in Ax 2012 that will help to understand
 Inventory structure. In AX 2012 Inventory structure has been completely changed. So in brief
 we can understand the same as:


Understanding the Product structure:


Product type
  Item type - This option will be selected if the product is an inventoried product
       Service type - This option will be selected if the product is a non-inventoried product

Product sub type

                 Product master - Products of this sub-type must have a product dimension group that
         specifies the product dimensions that are active for the product (color, size, and configuration)
o    Configuration technology
§  Predefined variant - This type should be chosen if the product will not be
  configured, but simply rely on the user’s choice of Color, and/or Size, and/or
  Configuration for each transaction
§  Dimension-based configuration - This type should be chosen if the user will 
  build a configurable BOM that relies on configuration rules to build the
  Config ID and the BOM lines. (This technology may only be chosen if 
  Configuration is active on the Product dimension group selected for the
  product)
§  Rule-based configuration - This type should be chosen if the product will
 use Product builder
§  Constraint-based configuration - This type should be chosen if the product
 will use the new AX 2009 Constraint based product configuration method. 
(This technology may only be chosen if Configuration is active and is the lone 
Product dimension active for the Product dimension group selected for the
 product)

         Product - Products of this sub-type do NOT have any product dimensions, and therefore do
    not have a product dimension group
        Product variant - A large amount of information may be maintained at the Product master
          level, including, but not   limited to:
o    Product dimensions
o    Images
o    Product categories
o    Product attributes
o   Unit conversions
For Product master products, Product dimensions and Product variants are
      extremely important. Both may be managed from menu items in the ribbons
      section of the Products form:

Dimensions
                                   Product dimensions: Color, Size, Configuration
                       Storage dimensions: Site, Warehouse, Location, Pallet ID
                       Tracking dimensions: Batch number, Serial number

Release product
Once product variants have been created at the instance level, they must be released
 to individual companies before transactions may be performed in the respective 
company. Variants may be released from any of the Products forms (All, Distinct,
 Product masters), or from the Product variants form by clicking Release products in 
the ribbon section of the form.
