System units define the units for length, mass, and volume that appear as suggested units of measure in Microsoft Dynamics AX.

Use the Preprocess fixed units form to set up the system units.


You must define shared units of measure before you can begin this task.

If you are upgrading to Microsoft Dynamics AX 2012 R2 or AX 2012 R3, you must identify a data partition when performing this task. If you have configured multiple partitions, the procedure must be repeated for each partition. For more information about data partitions and upgrade, see Configure partitions.

System units that are shared across all companies now replace fixed units, which were used in earlier versions of Microsoft Dynamics AX.

  1. Click Fixed units to open the Preprocess fixed units form.

  2. In the Partition key field, select a partition for preprocessing.

  3. In the Length, Mass, and Liquid volume fields, select the system units that you want to use.


    The units that you select must belong to the unit classes for length, mass, and liquid volume. You assign units of measure to unit classes in the Preprocess units form.

  4. Click Validate to check for validation errors.

  5. After you resolve all validation errors, click Set to ready for upgrade.
