MRP NAV 2015 - planning worksheet for purchase orders

  • 1.  MRP NAV 2015 - planning worksheet for purchase orders

    Posted Apr 01, 2021 12:32 PM
    Hello -

    Hoping someone may be able to help with an issue we are seeing when using the planning worksheet for purchase orders.

    Scenario
    We have a purchased item that when we run the worksheet instead of giving me an action message of reschedule in it is simply ignoring the released PO that is already in the system and asking me to create a new PO for a due date the week before.

    I would expect it to give me an attention and action message to rescheduling in a week so that it will meet the demand.

    On the purchase order the planning flexibility = unlimited (I believe all our PO's default to this)

    Item card
    Reorder policy = lot for lot
    Dampner Period = blank
    Dampner Quantity =  blank
    Rescheduling Period = blank

    I believe we are not getting the action message due to a setup issue but looking to see if anyone can give some advice.

    Thanks
    Kris

    Kristina,

    Based on the date moving CLOSER in time I was expecting to see Cancel/New suggestions from the system.  When you said it ignored the PO, I was expecting to see Planning Flexibility = None on the PO line.

    Is your demand source components on a Job?  I have seen some difficulties keeping Job supply/demand in sync, but generally not when it is Lot-for-Lot.

    Do you have any customizations or third party Extensions as part of your system?

    Just as FYI:
    Dampner Period controls the time period in which the system will ignore scheduling changes (generally within a few days) moving OUT in time.  Example: the demand shifts from the 15th to the 18th, and the Dampner Period is 5D, the system will leave the PO alone.  A Blank = 1D

    Rescheduling Period controls the length in time the system will suggest a reschedule when the demand moves OUT in time.  Example: the demand shifts from 4/15 to 5/15, and the Rescheduling Period is 2M, the system will suggest a reschedule.  OR If the Rescheduling Period was 14D, the system would suggest you cancel and create a new PO.  A blank = 1D

    Hi Ben -

    Thank you very much for the info.

    I've done some further testing with PO's and have another question.

    Today, when we create a PO for a product being made we assign the lot tracking on the item..  What I've noticed is if you add lot tracking on the PO, when you run the planning worksheet it will not give you any action message to reschedule.

    I removed the item tracking form the PO, re-ran the worksheet, and got the message to reschedule.

    Do you know how item tracking a lot number to line on a PO affects the planning worksheet meaning why doesn't it give signals to reschedule.

    Thanks so much.
    Kris

    The system thinks the Lot information was provided by the Vendor, therefore the Item is in the process of being received.

    What is the reasoning for adding the Lot No ahead of time?

    The standard process is to enter the Lot No at the time the product is received or when the info is provided by the Vendor.
