• What is the cause and solution for SAP error message RPM_DATA_CONSISTNECY028 - Object ID &1 is not unique within the project &2 ?

  The SAP error message RPM_DATA_CONSISTENCY028 indicates that there is a data consistency issue within the project management module, specifically related to the uniqueness of an object ID within a project. This error typically arises in the context of SAP Project System (PS) or SAP Portfolio and Project Management (PPM).
  Cause:
  The error occurs when the system detects that the object ID (e.g., a work breakdown structure (WBS) element, project, or activity) is not unique within the specified project. This can happen due to:
  
  Duplicate Entries: There may be multiple entries with the same object ID within the project.
  Data Migration Issues: If data has been migrated from another system or if there have been manual entries that were not properly validated, duplicates may have been created.
  Incorrect Configuration: The project structure may not have been set up correctly, leading to conflicts in object IDs.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Use transaction codes like CJ20N (Project Builder) or CJ03 (Display Project) to review the project structure and identify any duplicate object IDs.
  Look for WBS elements, activities, or other objects that may have the same ID.
  
  
  
  Correct the Duplicates:
  
  If duplicates are found, you will need to either delete or rename the duplicate entries to ensure that each object ID is unique within the project.
  Ensure that any changes made do not affect the integrity of the project structure.
  
  
  
  Data Validation:
  
  If the issue arose from data migration, consider running data validation checks to ensure that all entries conform to the required standards.
  Use tools like SAP Data Services or LSMW (Legacy System Migration Workbench) to clean up the data if necessary.
  
  
  
  Review Configuration:
  
  Check the project configuration settings to ensure that they are set up correctly and that there are no settings that could lead to the creation of duplicate IDs.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support notes related to this error for any specific guidance or patches that may address the issue.
