The Design tab displays the compatible units (CUs) in your design. If you do not have a design open, this tab will remain blank and you will not be able to send CUs to it. Use Workflow Manager to create and manage designs.
The Design tab displays the work request and its currently open design. A single work request can have multiple designs, but only one design may be opened and visible in ArcMap. A design may have multiple GIS units (GUs) and CUs assigned to it.
Design Objects and the Design Tab
When you have a design object selected (e.g., design, work request, work location), the Design tab displays two tabs in its user interface: Attributes and Extended Data.
The Attributes tab displays the geodatabase fields associated with the object.
The Extended Data tab allows you to view data specific to your work management system (WMS). The Extended Data tab appears only if a design is open and the design object has been properly configured (see Configuration Guide).
How the Design tab works depends on the setting selected in the ArcFM Properties Manager on the geodatabase in ArcCatalog. If you want to change this setting, contact your Administrator. To use the new features, the 'WORKFUNCTION' field on the Work Location feature class is required. If that field is not present, behavior will be the same as it was prior to this new functionality. See Design Tab for ArcFM 10.2.1a.
