In Progress
Material Purchasing Planning (contract manufacturer)

started a topic 7 months ago

We operate using a contract manufacturer so the majority of the heavy lifting concerning production is taken care of for us. We just need to make sure that we give a few weeks notice to get the production complete. 


We are however responsible for ensuring raw materials and components are in stock at our contract manufacturer.


A report in DEAR that would allow us to add multiple assemblies (at the same time) and then calculate what material we need to purchase based on what we already have in stock would be useful. This way we could run several different scenarios based on our forecasts.




  • Hi,


    There is an issue with the Co-Manufacturing functionality 


    When you raise the Co-Man Production Order you have to create Production Run 1 to generate the PO (and stock Tx).   This requires Production Run 1 to be for the full quantity.


    So, when the Co-man order is received in smaller batches, it can't be received into the system because Production run 1 (linked to the PO) can't have the quantity changed to match the receipted quantity from the PO.   The only way to change the quantity on the production order is to void that Production Run 1 which also voids the attached PO and Stock Transfer.  Voiding the PO contract is unacceptable, especially as it may well have prepayments against it synced into our accounting tool..


    The issue is that the system doesn't have a work around for the quantity amendment required in production run 1 on the Production Order (to keep the link to the PO).  Everything else is handled.   


    I'm happy to accept the logic of not having units per cycle for Co-Man but that doesn't mean the system shouldn't or can't have a workaround to allow the quantity in Production Run 1 to be amended.    


    In fact it needs that workaround - obviously - because the Co-Man function breaks if the supplier sends less than the full quantity of the PO and you need to use that partial receipt before the rest are sent.


  • Hello,


    In case if you know the planned received quantity from co-man, you can create several runs for Production Order. For example, Production Run is created for 10 items. But you know that you will receive only 5 items from co-man. You can change the Quantity to Produce in Production Run to 5 items before co-man operation is started. And then create the second Production Run.  

    The Purchase and Transfer orders are created by clicking the Start for co-man. Thus, if you change the quantity in Production Run before start of co-man, PO will be created for updated in run quantity.

  • Hi Elena - I can't see what you said '3 days ago'  Can you pm me or re-write your response.



  • Hello John Harley,


    In case if you know the planned received quantity from co-man, you  can create several runs for Production Order. For example, Production  Run is created for 10 items. But you know that you will receive only 5  items from co-man. You can change the Quantity to Produce in Production  Run to 5 items before co-man operation is started. And then create the  second Production Run.  

    The Purchase and Transfer orders are  created by clicking the Start for co-man. Thus, if you change the  quantity in Production Run before start of co-man, PO will be created  for updated in run quantity.

  • Hi Elena,


    I don't understand why your responses are no longer visible?


    Anyway, You say that we can break the PO down to smaller runs and the system will align smaller quantity PO's to these runs but that is explicitly what I said we can't do.  


    A single PO is required for the entire quantity & to raise this PO the first production run needs to be created & released for the entire quantity.  


    In some circumstances -  When the PO is raised it can't possibly be known how many items will be received back against the PO, we are likely to receive multiple batches of parts against this PO.  To elaborate, we will do a run of say 1000 machined parts that we will send to the surface treatment plant for anodising.   At this point we want to generate the PO for 1000 x Surface treatments with our contract manufacturer  and transfer 1000x Machined parts to his location.   When he send us the first 117 completed parts (for example) we want to be able to complete production run #1 for 117 parts that are now available to use by our assembly team and create a second production run for the parts on the order not yet received.  so on and so forth.



    All we therefore need is the ability to amend the quantity of Production Run 1 when the first batch is received,  we can then push the remaining batches into future runs on the production order.


    So; 1 PO = Multiple receipts (just like an advanced PO).
