• What is the cause and solution for SAP error message /SAPAPO/ND520 - No demand exists for specified period ?

  The SAP error message /SAPAPO/ND520 No demand exists for specified period typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a user attempts to access or analyze demand data for a specific time period, but there is no demand data available for that period.
  Cause:
  
  
  No Demand Data: The most common cause is that there is simply no demand data recorded for the specified period. This could be due to various reasons, such as:
  
  The demand planning process has not been executed for that period.
  The demand data has not been created or transferred from the source system.
  The planning horizon is not set correctly, and the period falls outside of it.
  
  
  
  Incorrect Selection Criteria: The selection criteria used to retrieve the demand data may be incorrect, leading to no results being found.
  
  
  Data Deletion: Demand data may have been deleted or archived, making it unavailable for the specified period.
  
  
  Planning Version: The planning version being used may not contain any demand data for the specified period.
  
  
  Solution:
  
  
  Check Demand Data: Verify if there is any demand data for the specified period. You can do this by checking the demand planning tables or using transaction codes like /SAPAPO/SDP94 (for demand planning) to see if any data exists.
  
  
  Adjust Selection Criteria: Review and adjust the selection criteria to ensure that you are looking for the correct data. Make sure the time period, product, location, and other parameters are set correctly.
  
  
  Run Planning Processes: If no demand data exists, ensure that the relevant planning processes (like demand planning or forecast generation) have been executed for that period. You may need to run the planning run again to generate the necessary data.
  
  
  Check Planning Version: Ensure that you are using the correct planning version that contains the demand data. You can switch to a different version if necessary.
  
  
  Consult with IT or Basis Team: If you suspect that data deletion or archiving has occurred, consult with your IT or Basis team to check the data retention policies and see if the data can be restored.
  
  
  Related Information:

  Planning Books and Data Views: Understand how planning books and data views are set up in your APO system, as they can affect the visibility of demand data.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to demand data in your version of SAP APO.
