  Data Inconsistencies: There may be inconsistencies in the data related to the material request, such as invalid or missing entries in the material master or planning data.
  
  
  Planning Parameters: The planning parameters for the constellation may not allow for the requested material. This could include settings related to lead times, lot sizes, or other constraints.
  
  
  Resource Availability: The resources required to fulfill the material request may not be available, leading to the inability to process the request.
