Here is one idea: -Have the unit records be auto numbered in Salesforce. This will create a sequence that can be used to determine what the previous record was - create a condition that displays only Incomplete units. --Sort the unit model in as sending order based on the Salesforce auto number field. - restrict the number of records allowed to load in the model to 1. The idea is that no completed records would be displayed and only 1 incomplete record will be displayed which would be the lowest sequentially numbered record that is marked incomplete.
