Error description

  • Customer has developed an IDOC D/S job.
    
    The user exports the job design only.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All parallel jobs using IDoc stage
    ****************************************************************
    PROBLEM DESCRIPTION:
    Importing a particular job which has not been compiled takes
    less than 1 minute.  Once the job is compiled and exported
    (including job executable) it takes over 30 minutes to import.
         This problem occurs when
    the job is using the parallel canvas   and contains the IDoc
    stage.
    ****************************************************************
    RECOMMENDATION:
    Install the patch if you have parallel jobs using the IDoc
    stageand long import times are impacting your project.
    This change is included in 8.0.1 Fix Pack 2.
    ****************************************************************
    

Problem conclusion

  • The IDoc stage on the parallel canvas in particular produces a
    single line of 3 million characters long when it is compiled,
    and this line is stored in the job.  When the job is imported,
    this line goes through a layer of code to convert DSX format
    escaping into the correct characters.  This part of the code is
    inefficient for long lines and has been corrected to perform
    better.  Using the same job which originally took over 30
    minutes to     import, with the patch applied import now takes
    around 2 minutes.
