Microsoft Dynamics AX Inventory Tables & Classes

Hi Folks,

The inventDim table is table that holds the combinations of inventory attributes assigned to items at they progress through inventory transactions. For example, an item can be located in many different warehouse, at may different sites, and stored in certain locations. Imagine the number of combinations that can be associated with an items its endless.  Below are the inventory dimensions AX uses to segregate items as they process through the system

InventColorId Item table contains information about colors.
InventSizeId Item table contains information about item size.
ConfigId  table contains information about available configuration of the various items.
InventBatchId table contains information about batches.
InventSerialId table contains information about item serial numbers.
InventLocationId table contains information about warehouses.
InventSiteId table contains information about sites.
wmsLocationId table contains information about locations.
wmsPalletId table contains information about pallets.

The inventTrans table is what I like to call the parent table of all transactions. NO matter what is performed a record will be written to this table when posting occurs. The inventTrans table represents a flow of inventory transactions as data leaves and enters a company for example. If a product is ordered a status field will be set to ordered. If a item is transferred from one warehouse to another warehouse the status will then be set to transfer. The inventory transactions table is typically used for very detailed inventory reports.

InventSum classes are used to find the on-hand information of a certain item at a certain date. The InventOnHand class is used to find the current on-hand information.

InventMovement class validates and prepares data that will be used to generate inventory transactions. All the classes related to the inventMovement class will be prefixed with InvMov

For instance the InvMove_Transfer preps data for inventory transfer journals

The InventUpdate classes are used to insert and update inventory transactions. Whenever a transaction should be posted, the updateNow() method in the correct InventUpdate subclass will execute. The super class in the hierarchy is the InventUpdate class, and the other classes in the hierarchy are prefixed ‘InventUpd_’. For example, InventUpd_Estimated is used whenever an item line is entered in the system that will most likely generate a physical transaction in the future. A good example can be a sales order line that has the on-order sales status. When a line like this is entered or generated in AX, the InventUpd_Estimated is triggered so that the inventory transactions will reflect that the item is on-order can is taken into consideration when the same item is ordered.

Thanks & Happy DaXing…..
