This typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with planning objects like product planning, demand planning, or similar scenarios.
  Cause:
  The error arises when the validity periods (horizons) of different planning objects or components overlap in a way that is not allowed by the system. This can happen due to:
  
  Incorrect Configuration: The validity periods for different planning objects may have been set incorrectly, leading to overlaps.
  Data Entry Errors: Manual entries for planning horizons may have been incorrectly inputted, causing overlaps.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Validity Periods: Review the validity periods of the planning objects involved. Ensure that there are no overlaps. You can do this by navigating to the relevant planning object in the SAP GUI and checking the validity settings.

  Review Configuration Settings: If the issue persists, check the configuration settings for the planning area or the specific planning object. Ensure that the settings align with your business requirements and do not allow for overlapping horizons.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on setting up validity periods in APO.
  
  
  Testing: After making adjustments, test the changes in a development or quality environment before applying them to production to ensure that the issue is resolved.
