Case 1

Item Details Qty. Case 1 Date parameter Date
Qt. on Hand 25 Starting Date 24/01/01
Safety Stock 40 Ending Date 24/12/31
In Purchase 15 on 23/12/01 Different Starting & Ending Date No
5 on 24/01/10 Starting Date Supply n.a.
In Sales 20 on 20/03/2024 Ending Date Supply n.a.
30 on 10/01/2025 Starting Date Demand n.a.

Understand the use of starting and ending dates in the calculation

Easy Purchasing requires there is a Starting Date and an Ending Date for the calculation. All requisition and supply will be filtered according to the given Starting Date and Ending Date in the request form. If you want to use alternate periods for the calculation of supply and demand you can enable Use different Starting Date and Ending date for Supply and Demand calculation in the Easy Purchasing Setup

Easy Purchasing - Case 2 Calculate Plan

Case 2

Quantity to supply (15) = Safety Stock Quantity (40) + Total of Demand (20) - Total of Supply (20) – Quantity on Hand (25)

You can set up the Starting and Ending Dates to ignore a Starting or Ending Date. This can be useful when you want to include all previous supply for example. When you set the option to ignore a Starting or Ending Date in the Easy Purchasing Setup, the date filter for the field will be set to unlimited when calculating the supply or demand. The ignored field will also be disabled in the request form Calculate Plan (Easy Purchasing)

Ignore Starting and Ending Dates

Set Ignore Starting Date for Supply Calculation to TRUE

Effect on Calculate Plan: Sets Ending Date Supply to 31-12-2024 and will calculate all the supply till date 31-12-2024.

set Ignore Ending Date for Demand Calculation to TRUE

Effect on Calculate Plan: Sets Starting Date Demand to 1-1-2024 and will calculate all the demand from 1-1-2024.
