This error typically arises during the planning process when the system is unable to determine a valid availability date for a product or resource due to various reasons.
  Causes:
  
  Resource Constraints: The resources required for production may be fully booked or unavailable, leading to scheduling conflicts.
  Incorrect Master Data: Issues with master data such as incorrect lead times, production versions, or resource settings can cause scheduling errors.

  Solutions:
  
  Check Resource Availability: Review the availability of resources and ensure that they are not overbooked. Adjust the scheduling of orders if necessary.
