Purpose

This document will go into greater detail on the use and setup of Planning Fence Rules and Planning Fence Days. Use this in addition to the 9.2 Online Requirements Planning Guide, Chapter 3.4.3 Time Fences and the Time Series.

Overview

Planning Fence Rules and Days are used by Material Requirements Planning (R3482 and R3483), to determine what sources of demand - sales (actual demand) or forecast, should be used within time periods. A rule of thumb is to set the planing fence days that would equate to replenishment lead time. Most Planning Fence Rules are used at the manufactured or 'M' level, but purchased components may also use if sold for spare parts, and requiring additional restrictions.

The planning fence rules can be viewed via the MRP Time Series (P3413). The S&D Inquiry uses the rules, but cannot be viewed. When troubleshooting issues, use the Time Series to properly calculate the demand sources.

Leaving the rule and fence days blank, will display all demand from both Sales and Forecast. When first testing MRP, it is recommended to leave these blank values, before adding restrictions to the item. It is also easier to see the impact of the rule type, and test with different rules and day combinations to find out what is right for the business needs.
