Specifically, it means that the coverage key is not unique, which can lead to issues in processing costs or charges associated with a project.
  Cause:
  
  Duplicate Coverage Keys: The most common cause of this error is that there are multiple entries in the system with the same coverage key. This can happen if the same key is assigned to different cost elements or if there are multiple records in the database that have not been properly managed.
  Configuration Issues: There may be issues in the configuration of the coverage keys in the system, leading to conflicts or overlaps.
  Data Entry Errors: Manual data entry errors can also lead to the creation of duplicate coverage keys.
  
  Solution:
  
  Identify Duplicates: Use transaction codes like SE16 or SE11 to check the relevant database tables (e.g., COVKEY or similar) for duplicate entries of the coverage key. You can run queries to find all instances of the coverage key in question.
  Correct Duplicates: Once duplicates are identified, you will need to either delete or modify the duplicate entries to ensure that each coverage key is unique.
  Review Configuration: Check the configuration settings for coverage keys in the system. Ensure that the settings are correct and that there are no overlaps in the definitions.
  Data Validation: Implement data validation checks to prevent the entry of duplicate coverage keys in the future. This can include user training or system checks during data entry.
  Consult Documentation: Review SAP documentation or consult with your SAP support team for specific guidelines related to coverage keys and their configuration.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CJ20N (Project Builder), CJI3 (Project Actual Line Items), and CJI5 (Project Actual/Plan/Variance) to analyze project costs and charges.
