• What is the cause and solution for SAP error message AJ688 - End of the last simulation period is not clear ?

  The SAP error message AJ688, which states "End of the last simulation period is not clear," typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with planning and simulation activities. This error indicates that the system is unable to determine the end of the last simulation period, which can hinder further processing or planning activities.
  Causes:
  
  Incomplete Simulation Data: The simulation data for the last period may not have been fully processed or saved, leading to ambiguity about the end of the simulation period.
  Configuration Issues: There may be configuration settings in the controlling area or planning version that are not set correctly, causing the system to be unable to identify the end of the simulation period.
  Missing or Incorrect Period Closing: If the previous periods have not been closed properly, the system may not recognize the end of the last simulation period.
  Data Consistency Issues: There may be inconsistencies in the data that prevent the system from determining the correct simulation period.
  
  Solutions:
  
  Check Simulation Data: Review the simulation data for the last period to ensure that it has been fully entered and saved. If necessary, re-enter or correct any missing or incorrect data.
  Review Configuration Settings: Verify the configuration settings in the controlling area and planning version. Ensure that all necessary settings are correctly configured to allow for proper simulation processing.
  Close Previous Periods: Ensure that all previous periods have been properly closed. If any periods are still open, close them to allow the system to recognize the end of the last simulation period.
  Run Consistency Checks: Use SAP tools to run consistency checks on the data to identify and resolve any inconsistencies that may be causing the error.
  Consult Documentation: Refer to SAP documentation or notes related to this error message for any specific guidance or patches that may address the issue.
