This error indicates that there is an attempt to create or modify a value for a specific operand in a season where that value already exists.
  Cause:
  
  Duplicate Entry: The primary cause of this error is that there is already an existing entry for the specified operand in the specified season. This could happen if you are trying to enter data that has already been recorded.
  Data Integrity Rules: The system enforces data integrity rules that prevent duplicate entries for certain operands within a defined season.
  
  Solution:
  
  Check Existing Values: Before attempting to create or modify an entry, check the existing values for the operand in the specified season. You can do this by navigating to the relevant transaction or report where these values are maintained.
  Modify Existing Entry: If you need to change the value, consider modifying the existing entry instead of creating a new one. This can often be done through the same interface where you would create a new entry.
  Delete Existing Entry: If the existing entry is no longer needed, you may delete it (if allowed) and then create the new entry. Ensure that this action complies with your organization's data management policies.
  Consult Documentation: Review the relevant SAP documentation or help files for specific instructions related to the module you are working with, as the steps may vary based on the context.
