DDMRP Calculate Buffer Value asks for Average Daily Usage

Posted on by Jefry Then 1,982

Hi everyone,

When I run calculate buffer values, I get an error message "You must specify the average daily usage for this item before we can calculate its minimum, maximum, and reorder-point stock levels."

From the documentation here, average daily usage in the coverage group is an optional field since this is a calculated field when we run buffer calculations.

So why do I get an error saying I need average daily usage to calculate buffer values if calculate buffer values will calculate the average daily usage? 

Kindly need your advice.

Thanks.

Jefry

    Got the same question, plus many more on this functionality. 

    Is the entity "Historical external demand" used in the ADU calculation?

    If not, how do I load historical daily usage information to start my project.

    Hi Dtyler4390,

    I think as long as we have any inventory transactions in FinOps, DDMRP can calculate ADU. 

    Based on my current understanding, DDMRP is intended to run daily and the decoupling point's main focus is the inventory level (minimum, reorder point, and maximum). So, It's not how to fulfil a demand directly.

    From the documentation here, for the past periods, ADU is calculated based on inventory transactions with status On order, Reserved ordered, Reserved physical, Picked, Deducted, or Sold. For the forward periods, DDMRP will calculate average daily usage based on our "forecast time fence" in our coverage group.

    But again, maybe there is something wrong with my understanding currently. Because with this understanding in my mind, I still have this error when running calculate buffer values.

    Jefry, make sure you have the item coverage setup to calculate buffer values over time to Yes, also when you run the Calculate buffer values batch job say Yes to Calculate average daily usage

    If you have transactions in the system for the Past and Forward the system should be able to generate the daily calculations

    This is great for an ongoing setup or movement from AX but doesn't work for migrations from other systems. You should be able to use historical external demand entity to load past sales.

    I spoke to PM about it and got "Good Idea" add to Idealist.

    Doesn't help my implementation of a large distribution operation.
