(PM) Item model groups (form)

Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012

Click Inventory management > Setup > Inventory > Item model groups.

Use this form to create and maintain item model groups. Item model groups contain settings that determine how items are controlled and handled on item receipts and issues. They also determine how item consumption is calculated. A model group can be associated with many items. This enables maintenance, because many items are often controlled with the same setup.

The following tables provide descriptions for the controls in this form.


The information is specific to Process manufacturing production and logistics.

For more information about the features and controls in this form, see:

 Item model groups (form).





Set up and maintain parameters for the selected item model group.

Inventory model

Select the inventory model.




Same batch selection

Select this check box if the inventory for a related sales order line is to be picked from the same inventory batch.


This field is available only if the batch number tracking dimension for the item is set to Active. The Coverage plan by dimension field must also be selected for the batch dimension. However, if the batch number dimension and serial number dimension are both active for an item, Same batch selection is not available. You set these dimensions in the Tracking dimension group form.

Consolidate requirement

Select this check box if future inventory to be reserved for sales order lines should be consolidated into a single requirement. This field is available only if the Same batch selection field is selected.

FEFO date-controlled

Performs "first-expired-first-out" date-controlled reservation, which is used only for shelf life items. Select this check box if the oldest inventory batch that fulfills the complete order quantity should be reserved. When you set this flag you can select the Pick criteria when you perform picking, manual or automatic reservation, or master planning.

Pick criteria

Select the option that determines the date for master planning calculations and reservation logic. This date is an internal setting that decides whether an inventory batch can be used. The following options are available:

  • Expiry date – This is calculated based on the shelf life days of the item added to the date of the batch production.

  • Best before date – This is calculated based on the Best before days deducted from the Expiry date.

These fields work together with the Sellable days value that is specified in the Sellable days by customer form. These fields ensure that the appropriate inventory batch is reserved or picked for customer orders.

Batch disposition code

Select the disposition code to use as the default code. The batch disposition code determines whether the inventory for a batch is available or unavailable for issue.

Purchase registration

If the item that is received has the tracking batch dimension active, this field enables vendor batch details to be updated during the purchase registration process.

If selected, the Vendor batch details form is displayed automatically when you click the Post All button in the Registration form.

Approved vendor check method

Select the default method to use for new items that are associated with the item model group. The values are as follows:

  • No check – Validation is performed, and any vendor that you select is enabled.

  • Warning only – A warning message is displayed, but you can continue with the transaction. This option is the default method.

  • Not allowed – An error message is displayed, and you must select an approved vendor to continue with the transaction.
