PM16474: Lethal Issue with DiffMerge

APAR status

• Closed as fixed if next.

Error description

• Summary:
  Lethal Issue with DiffMerge : The links of the Structure diagram
   go missing after merge leading to code issues.
  
  Description:
  In the attached zip you will find
  A) 3 sbs files (i.e. left, right and base)
  
  B) 4 Project folders which contains the above three sbs files an
  d the
  Merged sbs file respectively. Also the supporting sbs files and
  a
  Rhapsody Project which has the sbs files added to the model.
  C) A doc file with snapshots showing my Auto-Merge process.
  
  Open the Rhapsody Projects Left, Right, Base and Merged one by o
  ne. If
  there is any warning prompt ignore it. In each of the Projects
  
  navigate
  
  to:
  
  Packages -? OperatorAssistImplPkg -? NodeClass -? OperatorAssist
   -?
  Structure Diagrams -?
  
  OperatorAssist
  
  Look at the RED arrows in the structure diagrams in each of the
  
  projects. You will see that arrow heads exist in each of the Lef
  t,
  Right and Base projects but are not present in the Merged
  
  Project.
  
  
  This absence of the arrow head leads to the links being uninitia
  lized
  and hence unintended behavior of the code.
  
  
  As you can see from the snapshots of the merge decisions the Str
  ucture
  Diagram does not even show up as a DIFF between the versions.
  
  
  Customer Comments:
  Dif merge is a huge part of our development process.
  
  
  Business Impact:
  This problem has become very significant.  It is costing many ho
  urs per
  week fixing bad merges as well as having to rebuild/test our cod
  e.  I
  need someone to look into this ASAP.
