The purpose of the Material Requirements Planning Whitepaper is to increase your working knowledge of the MRP process within Acumatica. It is strongly recommended to first complete the M100, M200 Manufacturing Education course and be familiar with Acumatica Manufacturing processes and general MRP Configuration.


Upon the completion of the whitepaper the readers should understand:

  • Inputs to MRP and what parameters to consider if results are not as expected.
  • How a parameter impacts planning results and where it is used in the MRP regeneration process.
  • How MRP performs calculations
  • The results presented by MRP by working an example backwards.
  • Why exceptions are generated.

The following topics are not addressed in detail in the Whitepaper as they are well covered in the M100 and M200 Acumatica Education courses

  • What is MRP
  • How to configure basic MRP Preferences

The following topics are not included in this whitepaper, but may be addressed in a future:

  • Forecast generation see On-line help LINK
  • Dependent Forecast and Dependent MPS calculation and reduction

Hi ​@angierowley75 , the White paper is great thanks for sharing. I have questions on figure 32-34 why reorder points are not highlighted? isn’t true that based on Inventory Planning setting Safety stock or reorder point either should be considered? I also noticed in the Acumatica training and webinars it is only referred to the safety stock and no where is mentioned about the “reorder point” should we assume system only looks at safety stock? Example  

also there is a typo here. 

Thank you 

Ghazal

Currently, MRP/DRP treats Safety Stock and Reorder Point the same.  The calculation for the Reorder Point is the same as the calculation for Safety Stock.  When the QoH falls below the specified value, a planning recommendation is made to replenish it.

There is an active development project to improve this functionality.

There is also an Idea related to the improvement.

We will look to fix the typo and repost - thanks.
