• What is the cause and solution for SAP error message UCM0301 - Redundant characteristic &4 removed: &1 &2 &3 ?

  The SAP error message UCM0301, which states "Redundant characteristic &4 removed: &1 &2 &3," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with characteristics in InfoObjects or data models. This message indicates that a characteristic has been identified as redundant and has been removed from the data model or InfoObject.
  Cause:
  
  Redundant Characteristics: The error usually arises when there are multiple characteristics that serve the same purpose or have overlapping values. SAP identifies one of these characteristics as redundant and removes it to maintain data integrity and avoid confusion.
  Modeling Issues: It can also occur due to incorrect modeling practices, such as having characteristics that are not properly defined or that do not contribute unique information to the data model.
  Data Source Changes: Changes in the underlying data source or the way data is being extracted can lead to characteristics being deemed redundant.
  
  Solution:
  
  Review Characteristics: Check the characteristics involved in the error message. Analyze their definitions and ensure that they are distinct and necessary for your data model.
  Adjust Data Model: If you find that certain characteristics are indeed redundant, consider removing or consolidating them in your data model to avoid conflicts.
  Reconfigure InfoObjects: If the characteristics are part of InfoObjects, you may need to reconfigure them to ensure that they are set up correctly and do not overlap in functionality.
  Check Data Sources: Review the data sources and extraction processes to ensure that they are aligned with the characteristics you want to keep. Make sure that the data being pulled does not lead to redundancy.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to your version of SAP BW or HANA, as there may be version-specific considerations.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
