  Solution:
  
  Check Substitution Settings: Verify that the substitution settings for the material in question are correctly configured. Ensure that there are valid substitutes defined in the system.
  Review Material Master Data: Check the material master data for the item to ensure that it is correctly set up and that there are no restrictions that would prevent substitution.
