Only CU's (compatible units) are listed in the Design tab of the ArcFM Attribute Editor. It appears as though the GIS features have been removed from the design, although their symbols may still appear on the map. See the following images.
This only affects clients who utilize both Designs (Workflow Manager) and Sessions (Session Manager) in the same environment.
This issue may be related to the following bug resolved in ArcFM 9.3.1 SP1.
MM40006: Session Manager -- SessionDeleter deletes from MM_HIDDEN_PACKAGES where SessionID = Name(DesignID).
The problem occurs when sessionIDs overlap with designIDs.
The workaround is to increase the value of the MM_PX_SEQUENCE SessionID field to avoid overlapping with Design IDs.
A patch is available for the following versions.
9.3 Rev 2
