  The SAP error message C2357, which states "Reservation item &1: By-products not possible," typically occurs in the context of production planning and inventory management. This error indicates that there is an issue with the reservation item in relation to by-products in a production order or reservation.

  Reservation Type: The type of reservation being created may not support by-products. Certain reservation types may have restrictions on handling by-products.

  Solution:
  
  Check Material Master: Ensure that the material master for the main product and any by-products is correctly configured. This includes checking the "By-Product" indicator in the material master.
  Review Production Order: Verify the production order settings to ensure that by-products are allowed. Check the routing and ensure that by-products are defined in the process.

  Consult Documentation: Review SAP documentation or help files related to by-products and reservations to ensure compliance with best practices.
  System Configuration: If necessary, consult with your SAP Basis or configuration team to ensure that the system settings allow for by-products in reservations.
