Validation checks values entered by the user and substitutes incorrect values, while substitution removes incorrect values entered by the user. Validations can be applied at the document header, line item, and master data level to check for values like company code and business area. Substitutions can also be applied at various levels to replace values like profit centers or business areas. Both validations and substitutions use user exits and can be transported between systems after configuration.
