  The SAP error message /SAPAPO/ND505 Enter non-overlapping periods typically occurs in the context of SAP Advanced Planning and Optimization (APO) when users attempt to enter or manipulate planning periods that overlap in a way that is not allowed by the system. This error is often encountered in scenarios involving planning books, data views, or when defining time periods for planning activities.
  Cause:
  The error is triggered when:
  
  Overlapping Time Periods: The user is trying to enter periods (e.g., planning intervals, time buckets) that overlap with existing periods. For example, if you have a period defined from January 1 to January 10, and you try to define another period from January 5 to January 15, this will cause the error.
  Incorrect Configuration: The configuration of the planning book or the data view may not allow for overlapping periods, which is a common requirement in planning scenarios to ensure data integrity and accuracy.

  Review Planning Book Configuration: If you have access to the configuration settings, check the planning book settings to ensure that they are set up correctly to handle the periods you are trying to enter.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on how to define periods in your planning book or data view.
