  The SAP error message /PM0/ABB_MESSAGES421 indicates that there is an issue with the assignment of rankings in a subcoverage type. Specifically, it states that a ranking (denoted as &1) cannot be assigned more than once within the specified subcoverage type (denoted as &2). This typically occurs in the context of configuration or data entry in SAP modules related to project management, service management, or similar areas where rankings or priorities are assigned to items.
  Cause:
  
  Duplicate Ranking Assignment: The most common cause of this error is that the same ranking value is being assigned to multiple entries within the same subcoverage type. This violates the uniqueness constraint for rankings in that context.
  Configuration Issues: There may be a misconfiguration in the system settings that allows for duplicate rankings to be attempted.
  Data Entry Errors: Users may inadvertently enter the same ranking for different items without realizing it.
  
  Solution:
  
  Check for Duplicates: Review the entries in the subcoverage type specified in the error message. Look for any duplicate rankings that may have been assigned. Ensure that each ranking is unique within that subcoverage type.
  Modify Rankings: If duplicates are found, modify the rankings to ensure that each one is unique. This may involve changing the ranking of one or more entries.
  Review Configuration: If the issue persists, review the configuration settings for the subcoverage type to ensure that it is set up correctly and does not allow for duplicate rankings.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on how rankings should be assigned within the context of your specific module or application.
  User Training: If data entry errors are common, consider providing additional training to users on how to properly assign rankings to avoid this issue in the future.
