Use rounding methods to create rounding rules that enable you to calculate a final base price. Sales price uses three types of rounding rules:

• Mathematical rounding.
• Price point rounding.
• A combination of mathematical rounding and price point rounding. For this method, the system uses mathematical rounding first, followed by price point rounding.

Use the Rounding Rules program (PCW19) to create rounding rules based on mathematical rounding methods, price point rounding methods, or a combination of the two. The system stores rounding rules in the Rounding Rules table (FCW36).

Prerequisites
Before setting up rounding methods and rounding rules, verify that the following UDCs are set up: 

• UDC 41F/RT
• UDC 41F/RM
• UDC 41F/ST
