Use on hand inventory as safety stock


I am having a problem using on hand inventory as safety stock. So, even if I have more inventory on hand than the minimum stock key, a replenishment order is created.

The "Fulfill minimum" key is set as "Today" but as I get it, if I have enough inventory I should not have an order to replenish the safety stock today.

Negative days are set as zero and positive days are 365.

Any ideas?

Thank you all.

    I dont have time at the moment to re-run it, but I could only do it in CU10, I will try soon, but it will work for me, mainly because that is the way it has always worked in the years I have been doing this :-)

    Your next test on that item is to remove all demand, so delete any forecast - run planning, it should tell you to do nothing - does it? If it does not what is the planned supply pegged against?

    Hello Adam,

    If I remove the demand it doesn't create any order.

    There's the full picture of the net requirements.



  • In reply to Nacho Garcia:

    The first thing it has done as expected :-)

    Now raise a sales order due in 30 days time, run the planning - it should tell you a refill in 30 days.
    Then delete the sales order and enter a single demand forecast line for the same date. The logic would be it would be the same, but I am guessing it will not, so we then need to look at forecast consumption settings, but try these two first.
  • In reply to AdamRoue:

    Now there are two possibilities:

    • Sales order doesn't take available stock below minimum stock

    • Sales order does take available stock below minimum:

    There you are, a planned order to refill stock above minimum placed today. It will do the same with forecast.

  • In reply to Nacho Garcia:

    I would not worry demand forecast it will be the same, the question is why the planned production is moving to immediate when it is not needed. Let me try to break it like you have :-)
  • In reply to Nacho Garcia:

    Just curious, but why is the reference field showing "planned works orders"? That doesn't look like something created organically through the MRP process...
  • In reply to Chan Stevens:

    It is because the item is a production item, it is not purchased, it is made.
  • In reply to AdamRoue:

    My point was that I don't think the term "planned works orders" is what AX uses. I believe that AX would use "planned production order". AX doesn't use "works" and wouldn't typo the plural orders for the singular order record. That looks like evidence of a customization.
  • In reply to Chan Stevens:

    Sorry missed that point! I thought that was a language element to be honest but worth an ask
  • In reply to AdamRoue:

    Split the difference :-) I just checked and AX does throw the plural "orders" on every single planned production order record, but definitely doesn't use "works".
  • In reply to Chan Stevens:

    OK. It's a language issue. I had AX2012 set to EN-GB, if I set AX2012 to EN-US it changes to Planned production orders:

    Good to know!



  • In reply to Chan Stevens:

    Hi Chan, I've just set my settings with EN-GB lenguaje, I review the enums for the (ReqTrans).RefType that you pointed out. "Planned works order" is a valid label, there is no customization there.

    Nacho... the finished product you are using, are you creating it from scratch inside AX with native functionality? Are you using any customization or import tool to create the item?

    Hi Hector,

    I began with an already created product but recently I created a completely new one by hand without any tool.
  • In reply to Nacho Garcia:

    Hi Nacho

    I cannot break it to do what you are seeing. I am only on a CU10 system but I have played around with the coverage settings and the plan settings, I cannot get the planned production order to move to today when the demand creation is triggered by a sales order in the future breaking the minimum stock level. I have looked at the whats new for CU12 and there are no new flags around demand and CU11 only has performance impact.

    We removed the forecast elements so there is nothing there, the items are not batch controlled so there is no expiry impact or indeed stock impact.

    There are however a few things I want you to do
    1. I note this is a CatchWeight item - is this true? If it is can you please test the same scenario on a non-Catchweight item.
    2. Can you tell me which dimensions group elements are set to item coverage, it looks like Site and Warehouse.
    3. Can you post a screen shot of your static plan general tab please.

  • In reply to AdamRoue:

    Hi Steve,

    As long as I know this is not a CatchWeight item:

    Dimension group are the following:

    Static plan has the following configuration:

    And the planning table is empty because I'm not using it:

    Thank you very much,
