  Cause
  This error occurs during the planning run in SAP Warehouse Management (WM) or during the creation of transfer orders when the system tries to determine the next planning time period for a material but fails. The main reasons include:
  
  
  Missing or Incorrect Planning Time Periods:
  
  The system cannot find a valid next planning time period in the planning calendar or planning horizon for the material.
  
  
  
  Incorrect or Missing Planning Calendar:
  
  The planning calendar assigned to the material or warehouse number is not maintained or does not cover the required dates.
  
  
  
  Planning Horizon or Period Settings:
  
  The planning horizon or period settings in the system are not correctly defined or are too restrictive, so the system cannot calculate the next period.
