  Incorrect Planning Version: The planning version being used may not have the necessary data. If the version is not set up correctly or is inactive, it may lead to this error.
  
  
  Data Activation Issues: If the data has not been activated or has been incorrectly activated in the APO system, it may not be available for planning.
  
  
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to access the product or location data.
  
  
  Selection Criteria: The selection criteria used in the planning run may not match any existing products or locations, leading to no data being found.

  Data Activation: If there are issues with data activation, ensure that the data is properly activated in the APO system. You may need to run the data activation process again.

  Check for Errors in Data Transfer: If data is being transferred from SAP ERP to APO, check for any errors in the data transfer process that may have resulted in missing data.
