  The SAP error message AFWGO_MESSAGES420 indicates that there are already existing key figure values for a specified benchmark and key figure within a defined time period. This error typically arises in the context of planning or forecasting scenarios in SAP, particularly when working with the SAP Integrated Business Planning (IBP) or SAP Advanced Planning and Optimization (APO) modules.
  Cause:
  The error occurs when you attempt to enter or upload key figure values that overlap with existing values for the same benchmark and key figure within the specified date range. This can happen due to:
  
  Duplicate data entries.
  An attempt to overwrite existing data without the necessary permissions or settings.
  Incorrect configuration of the planning area or key figures.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Data: Review the existing key figure values for the specified benchmark and key figure within the date range mentioned in the error message. You can do this by querying the relevant planning area or using transaction codes like /SAPAPO/SDP94 for planning book analysis.
  
  
  Modify Input Data: If you are trying to upload or enter new data, ensure that the new values do not overlap with existing values. You may need to adjust the date range or the key figure values you are trying to input.
  
  
  Delete or Adjust Existing Values: If the existing values are no longer needed, you can delete or adjust them to make room for the new entries. Be cautious with this approach, as it may affect other planning processes.
  
  
  Check Configuration: Ensure that the configuration for the planning area and key figures is set up correctly. This includes checking the settings for data locking, overwrite permissions, and any relevant planning functions.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling key figure values and planning scenarios.
