Master planning (MRP/ planning optimization) fine tuning to ensure additional planned orders are not generated when there is some incoming supply in Microsoft Dynamics 365 Finance and Operations

Master planning MRP fine tuning to ensure additional planned orders are not generated when there is some incoming supply in Microsoft Dynamics 365 Finance and Operations

Important switch/config in MRP is usage of NEGATIVE and POSITIVE DAYS

while lot is available on positive days, keen to share something on negative days and planning optimization

Turn on in Master planning parameters: Use dynamic negative days

Select this option to use dynamic negative days in master scheduling calculations. This option and the Negative days field control when to use a scheduled receipt to fulfill a requirement, or when to generate a planned order instead. By using dynamic negative days, you can include the factor of remaining item lead time in the calculation. This provides increased accuracy in the master scheduling results. The formula for calculating dynamic negative days is: Negative days = Lead time + negative days – min{lead time, requirement due date – today's date}. The Negative days field is in the Item coverage and Coverage groups pages.

DO NOT FORGET TO Enable feature in planning optimization to use negative days
