Traceability Link 'Traceability Link' (Traceability Link): Both link extremities should be defined

Hi,

I need some help with Traceability Links. I'm getting following error message when checking in the model into the repository:

  Traceability Link 'Business Process Model 'Corporate Funding Back Office'' (Business Process Model 'Corporate Funding Back Office'): Both link extremities should be defined

The check in of the document has been cancelled.

I don't undestand the error message, since everything looks OK:

1. Outgoing Traceability Link

2. Incomming Traceability Link

And this is how it looks like in the Impact Analysis:

This is the procedure I'm using to create the Traceability Links:

Sub CreateOTL(linkSource, linkTarget)
   Dim otl, otl_exists, new_otl
   otl_exists = FALSE
  
   For Each otl In linkSource.OutgoingTraceabilityLinks
      If (otl.SourceObject = linkSource) Then
         If (otl.LinkedObject.isShortcut()) Then
            If Not (otl.LinkedObject.TargetObject Is Nothing) Then
               If (otl.LinkedObject.TargetObject = linkTarget) Then
                  otl_exists = TRUE
               End If
            End If
         Else
            If (otl.LinkedObject = linkTarget) Then
               otl_exists = TRUE
            End If
         End If
      End If
      If (otl_exists) Then
         Exit For
      End If
   Next

   If Not (otl_exists) Then
      Set new_otl = linkSource.Model.CreateObject(cls_ExtendedDependency)
      new_otl.LinkType = "Created automatically by Sync Script"
      linkSource.OutgoingTraceabilityLinks.Add(new_otl)
      linkTarget.IncomingTraceabilityLinks.Add(new_otl)
     
      Print "INFO", "OutputTraceabilityLink >>> " + linkSource + " (from " + linkSource.Model + ") --> " + linkTarget + " (from " + linkTarget.Model + ") <<< created"
   Else
      Print "DEBUG", "OutputTraceabilityLink >>> " + linkSource + " (from " + linkSource.Model + ") --> " + linkTarget + " (from " + linkTarget.Model + ") <<< already exists"
   End If
End Sub

What am I doing wrong? The links looks OK, the only problem is the Chech-In

Any ideas?
