The Manage CUs tab allows you to view, create, edit, or delete compatible units (CUs). Designer now uses CU referencing to better manage compatible units. CU referencing does not require any configuration.

Search

Use the Search field at the top of the Compatible Units list to search the list of CUs. Enter one or more characters. The list will display only the CUs that contain the string of characters you have entered. The list filters as you type.

To clear the search, delete the contents of the field or click the X to the right of the Search field.

Create CU

Use the Manage CUs tab to add compatible units to the CU library. You can create either spatial or non-spatial CUs.

On the Manage CUs tab, click the Create New button. This brings up the New Compatible Unit window.
In the New Compatible Unit window, select a Feature or Object class. Select <None> to create a non-spatial CU.

Select <None> in the Feature/Object Class field to create a non-spatial (or non-GIS) CU.

Select a Subtype. If the selected feature or object class does not have a Subtype, this field will be disabled.
Enter a WMS code.

Click Continue to create the CU. Click Cancel to return to the Manage CUs dialog without creating the CU.

After you've clicked Continue on the New Compatible Unit screen, the new CU will be selected in the Compatible Units list. Edit the associated information in the right column. This includes General Information, Design, Extended Data (if it exists), and Defining Attributes.

When you create multiple CUs with the same WMS code but a different subtype, we recommend you use the same description for each (in both the MM_CU_LIBRARY and MM_WMS_COMPATIBLE_UNIT_LIBRARY tables). In these cases, use the name field to differentiate which CUs represent your data model. Following this advice will prevent issues with display namers.

If you click Cancel at this point (or somehow fail to save), the new CU will not be saved to the Compatible Units list.

Click Save to add the new CU to the CU list.
If the new CU needs to be available for designs in Workflow Manager, you must add the CU to the MM_WMS_COMPATIBLE_UNIT_LIBRARY table.

Edit

Once you have selected a CU from the list, you can edit it using the column at the right side of the screen. This column allows you to edit various types of information about the CU.

General Information: This section allows you to edit the name and description associated with the CU. The Code is assigned to the CU when it is created and cannot be modified.

Typically, the following characters are invalid for CU naming: $ ^ * + | ?. Although we strongly recommend keeping this behavior, you can edit your Windows registry to accept these characters in CU naming. See the Allow Invalid Characters in CU Naming topic for more information.

Design: Use this section to modify the Designer-specific field values for the selected CU. This includes Workflow Status, Work Function, Units of Measure, and Available Work Functions.

An ArcFM Properties Manager option on the geodatabase allows you to remove "None" from the list of Work Functions in the CU Filter.

Clear the checkbox to remove the None option from the Work Function field in the CU Filter. If you give a CU only the work function of None, it will not appear in the CU Filter in ArcMap. This may be used to "retire" CUs that are no longer used.

Extended Data: If there is extended data associated with the selected CU, you can edit it here. If no extended data exists, this section will be empty. Refer to Extended Data section for more information about adding extended data to your CUs.

Event Log Warnings: In some cases you may experience a number of warnings in the event log when placing CUs in an open design. These warnings indicate old extended data attributes exist on the CU, but are not configured in Workflow Manager. The process to clean up old extended data attributes is complex and involves modifying the MM_CU_Extended_Data table as well as the XML for CUs and Favorites. It is safe to ignore these warnings.

Defining Attributes: This section displays the defining attributes for the CU. These are set when the CU is created and cannot be edited. However, you can edit the Work Function value associated with the CU.

The fields in the Defining Attributes list are determined by the value of the CU Defining field on the Field Info tab in the ArcFM Properties Manager. Any field with a CU Defining value of Yes will appear in the Defining Attributes list.

Click Save to save any changes you've made to the selected CU. If you attempt to select another CU before saving, you will be prompted to save the current CU first.

Click Cancel to undo any changes you've made and return the fields to the values assigned before you started editing.

Delete

To delete an existing CU, select it in the list and click the Delete button. You will be prompted to confirm that you want to delete the selected CU. Once deleted, a CU cannot be restored. It will have to be recreated. You can only delete one CU at a time.
