The document discusses the key elements involved in the pricing procedure in SAP, including condition tables, access sequences, condition types, condition records, schema groups, and calculation schemas. Condition tables store pricing data fields, access sequences define the search strategy to find pricing data, condition types represent different charge types like price and discount, and condition records store the pricing values. Schema groups are assigned to vendors and purchase organizations and determine the applicable pricing procedure. Finally, calculation schemas define the sequence of condition types used in the pricing procedure to calculate the final price.
