The LoadNames view was not created or does not have the MspLoadNames model name assigned. Network Adapter exports loads from the LoadCase table. In order to manage the size of the LoadCase table, Network Adapter creates a view on that table containing unique load names. The Network Adapter Implementation Guide includes a page called Supported Attributes for MultiSpeak Loads, which describes how to configure the LoadCase table, a related feature class, and the LoadNames view.
