MRP Recalc Required - Control Supply and Demand with SapphireOne

Inventory > Inventory > Inventory Locations > MRP Recalc Required

MRP Recalc Required Overview

Material Requirements Planning (MRP) is a strategic supply planning method designed to assist organisations, particularly those in manufacturing, in understanding and managing their inventory needs. By maintaining a balance between supply and demand, MRP systems enable effective inventory management, production scheduling, and timely, cost-efficient delivery of finished goods.

The primary function of the MRP Recalc Required tool within SapphireOne is to overwrite existing inventory quantities based on forecasts or orders – whichever is greater. This ensures that inventory levels are optimised to meet future demand.

Administering and utilising a forecast with your Sapphire MRP creates a dynamic link with predictive analysis and planning. The Sapphire MRP Recalc Required tool balances supply and demand, providing the SapphireOne end user with a specific supply inventory quantity to cater for future demand.

The predictive nature of the inventory required quantity offers an intuitive understanding that allows for the prediction of future supply. However, predictions can be incorrect due to various factors, leading to errors, instability, or signal distortion in MRP forecasting. The SapphireOne user can rebalance and redistribute any inaccuracies in the Sapphire MRP Recalc Required tool for up to 2.5 years into the future, while analysing up to 4 years of historical data. This tool enables continuous rebalancing in a changing plan and world.

The MRP Recalc Forecast and MRP Recalc Required tools performs the necessary calculations to order inventory required to bring inventory levels up to their maximum. If a Minimum – Maximum calculation is required, navigate to Utilities > Master Defaults > Inventory Page and select the “Re-Order Ignores the MRP Formula” checkbox.

MRP Recalc Required Procedure

As time and business progress throughout the year, an update to your MRP inventory required quantity may be necessary. This tool is available in both Inventory and Inventory Locations. If executed on a Base Inventory Inquiry, the forecast will be applied to all Inventory Locations. The procedure is as follows:

  1. Navigate to Inventory > Inventory > Inventory or Inventory > Inventory > Inventory Location.
  2. Select the items that need the recalculation procedure executed upon them. 
  1. Navigate to Tools > MRP > Recalc Required to initiate recalculation. The Sapphire tool will display an alert to verify that the recalculation of the current inventory required quantity is to be updated on the selected inventory records.
  2. Once the procedure is completed, SapphireOne will re-display the list of inventory items, now filtered to only the items selected for recalculation.

By following these steps, you can ensure that your organisation’s inventory levels are accurately maintained, supporting efficient production and timely delivery of goods.

Executing the recalculating procedure on a large number of inventory items can be time-consuming and should only be performed at the close of business for the day, allowing it to run overnight. This recommendation is particularly relevant for SapphireOne server sites with thousands of users.
