DDMRP Adjustment

Beta License: AGPL-3 OCA/ddmrp Translate me on Weblate Try me on Runbot

Allow to extend DDMRP App to be able to apply Adjustments for dynamically altering buffers for planned or anticipated events. This include:

  • Demand Adjustment Factor (DAF): is a manipulation of the ADU input within a specific time period. The system will look for existing DAFs when computing the ADU for each buffer and apply them. The system will also explode the resulting increase in demand of parent buffers to all their children buffers using the BoM.
  • Lead Time Adjustment Factor (LTAF): manipulates the Decoupled Lead Time for an individual part or group of parts (buffer profile, same partner...) to adjust for a planned or known expansions of LT.
  • Zone Adjustment Factor (ZAF): pending to implement

Table of contents


To plan buffer adjustments act as follows:

  1. Click on Inventory > Demand Planning > Create Buffer Adjustments.
  2. In the popup window fill the Period and Date Range Type to perform your planning.
  3. Check the boxes of the Factor to Apply in which you are interested.
  4. Select the DDMRP Buffers where to apply this factors.
  5. Under the title Sheet you will see a generated sheet in which you can fill the values for each period.
  6. Click Validate to confirm your planning and the system will end up showing you the newly created DDMRP adjustment records.

Known issues / Roadmap

  • Implement new factors
  • Reuse existing factor and modify them instead of always creating new ones.
  • Add small graph view in buffer form as a way to overview DAFs.
