This topic explains how to resolve an unresolved reference to a 
      design element in another process app. When you validate a
      process app, a list of unresolved references, if any, is displayed in the
      Validation Results at the bottom of the 
      
SBM Composer
        window. 
        
Tip: In many cases, the process app containing a referenced
          
          application is missing from the 
          repository (that
            is, the referenced application existed when the reference was created, but was
            later deleted). After you resolve the application reference, the references to
            other design elements in the referenced application are usually resolved
            automatically. 
        
 
        
 
        Unresolved references are displayed with a red X.
