Posted on by phong.pham 384

Hi All,

I got this issue below.

I run a master plan after that I firm planned order for FG item and Component item to Production Order. The next step I will update update batch number for FG and Component Item. But When I run a master planned again . I see the system create another planned order component which I already created on Production Order.

How can I prevent Master Planned create planned order for component which I already create on Production order.

Please note all FG item and Component item I control by batch number.

Thanks

    Hi Pham,

    Know that updating batch number doesn't block MRP to do what it is supposed to do.

    As far as MRP suggesting planned order - do you have inventory for component in stock? If not MRP will consider your production order component as demand and generate Planned order.

    Thanks,

    Hi Satish,

    We haven't got component Stock. 

    Your told me  MRP will consider our production order component as demand and generate Planned order.-> If We do like that when I firm planned order to Production order. The system will create double production order. 

    I don't know why MRP create more planned order of this component -> How can stop it. 

    I try to setup MRP by Makes to Order on dynamic 365 But I see it only works for finished good item. It doesn't work for sub component. The system always create more planned order for component.

    If system is suggesting planned order for component, it's only for component. It's not going to create production order for FG item. Suggest that you try this in non-production environment and get more clarity.

    Dear Satish,

    I don't know why the system create planned order for component. I already did a lot of testing on UAT.

    Planned order create component the same with Production Order.

    If I create production order for FG item , update batch number -> when I run MP the system doesn't create planned order for FG item.

    If I create Production order for Component Item , update batch number -> When I run MP the system create another planned order for component again.

    I do setup for FG item and component are the same. Both of them is setup with coverage group is Requirement. 

    I also setup tracking dimension group by batch number

    Thanks Pham for clarification. Can you check if your component production order has any inventory transactions. Do an estimation on component production order that you already created and run MRP again and see if it creates the planned production order for component again.

    Dear Satish,

    I has just reset status on Production. I reset status to Create and run MRP again -> I see the system don't create planned order for sub component any more. 

    It look like when production order status is Created. It will auto reservation subcomponent. 

    Please note - It only works correct when I reset status of Production Order is created. If I reset Production Order to Stated or Estimation It doesn't work.

    Do you know why I reset status of production order to Created -> the system don't create planned order for sub component again ?

    It's difficult to know without more info. Maybe your manually released order is for a different date than mrp calculates.

    Check messages and explanation tab and you should then understand the reasons.

    Negative days might reduce such problems.

    Do you run net change or full regeneration mrp?

    Hi ,

    I run MRP with Regeneration.

    What do you means with "Negative days might reduce such problems" ?

    I try to find a solutions -> If I already create production for sub component by batch number when I run MRP again -> the system doesn't create more planned order for this sub component again. Because Our company makes product by MTO.

    Please note I already setup sub component -> coverage group by REQ.

    Thanks

    If you run full regenerative mrp then it should take into account any manually created orders. It will  see the supply of that component.If it does not think the completion date for that component production is going to  be on time based on its calculations (which depend on many settings) then it will plan another orde;

    When your manually created order has a different start and end date than mrp expects then use of negative days (i.e.the days tolerance you can accept on a  date ) would trigger a message to either to redate or expedite rather than h=generate a new order.

    If you have approved an mrp planned order, but not firmed, then mrp will not plan it again for the same date and quantity.

    If you turn on messages and run mrp and look a the explanation tab then you may get a better  understanding of what mrp is doing  in your particular case..
