Infinite Rescheduling Horizon

Currently, the maximum rescheduling horizon is 999 days.  Our customer queues up sales orders out in 2025 until they have been approved.  When the order receives design approval from the customer, it is moved into the current period.  Most of the materials are not custom and purchase orders and production orders for long lead items are created while the sales order sits in 2025.  When the sales order is moved into 2007, new planned orders are created and the original purchase orders and production orders receive a cancellation message because they are outside the horizon. 
Is there any way to increase the rescheduling horizon to stop the duplication of orders?  Thank you in advance.

Hello Eric,
There is no option to increase the rescheduling horozon in customizing. Maximun will be 999 days only.
Why dont you limit the planning of the sales orders which are falling in 2025. You can limit this if you run the MRP with NETPL prpcessing key and defined some planning horizon (period) in customizing..for example 100 days...that means the sales orders whcih comes under these 100 working days from the day of the MRP are only relevent for the MRP and planned orders will be created for these sales orders only..for the rest of the orders there will be no planned orders.
There is no logic to have the planned orders for the requirements of the yesr 2025.
By doing this you can avoid cancellation messages and you can work with rescheduling horizon.
I still need the correct inputs from your side.

  • MRP-Rescheduling Horizon

    Hi Experts,
    Could u please, explain what is Rescheduling horizon (OMDQ)?
    In OMDQ , if I change planning horizon to 999 days from 100 days.What will be the effects of it?
    Thanks in advance

    Dear,
    The rescheduling horizon is the period in which the SAP System checks whether the existing dates still suit the requirements situation for receipt elements that can no longer be automatically changed in the planning run. If the dates of a particular element are no longer suitable, the following exception messages are created depending on the requirements situation.
    Rescheduling check is to change the dates of already existing firmed receipts which were not planned on the same day as the requirements day to suit the requirement.
    For this we need to define a rescheduling horizon.
    Rescheduling horizon defines the period for bringing the receipts that should be taken into account for rescheduling.
    For further info: Please visit: http://help.sap.com/saphelp_40b/helpdata/pt/b4/7055967935d1118b3f0060b03ca329/content.htm
    For second question, if you change it to 100 days,
    If you put 100 days, for net requirement calculation, system will consider the firmed planned orders & receipts within 100 days.
    If one firmed planned order is in 4 months before ie 120 days before, system will not consider for net req calculation.
    Say demand is 100 on 23.09.08
    Resheduling Horizon 100 days
    Firmed planned order in 23.04.08
    When MRP run system create planned order for 100 qty.
    If rescheduling horizon 999 days, system will not create planned order & system propose reschedule the firm planned order to 23.09.08

    Hi,
    The rescheduling horizon, defines the period for bringing forward the receipts, and the receipt elements, which should be taken into account in rescheduling, are included in these.
    In your example, you will get an exception message (depending on the tolerance values you have defined)to postpone the process , since the Sale Order is before the requirement.
    pls refer the foll links

  • Rescheduling horizon impact on net requirement calculation

    Dear MRP experts ,
    What is the impact of Recrudescing horizon on net requirement calculation .
    Regards
    Sasikanth

    Dear Sashikant,
    The rescheduling check is used to change the dates of already existing firmed receipts not planned on the same day as the requirement to suit the requirement date.
    If you look at MD04, the rescheduling date is based on the Stocks Requirement date. 
    In the net requirements calculation, the system checks whether warehouse stock or firmed receipts are available to cover requirements. If a material shortage exists, the system usually creates a new procurement proposal.
    Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.
    hope it helps. please revert back.

  • Rescheduling horizon at 999

    Hello, we set our rescheduling horizon at 999 days for the correct MRP group in configuration, however when we run MD04, the date of 12/24/2018 did not reschedule. It should have pulled it in. We put the date of 12/24/2018 as a test to see if it would pull it in to within the 999 days, but it did not. What else could be causing the problem?  Everything in the material master looks fine.
    Thank you.

    Hi,
    What do you mean by "it should have pulled it in"? Are you expecting the PO lying outside the 999 day horizon to be brought inside it by MRP?

    If yes, then that's not the intended functionality. The functionality is intended to check if any firmed proposals that exist in future can cover new requirements by rescheduling the proposal. If true, the system will propose rescheduling. The original proposal should however be within the rescheduling horizon.
    In your case, the PO could very well be outside the 999 horizon as pointed by Caetano. Besides, you have a situation of surplus. Both your customer orders are already covered by the stock and planned order and MRP has proposed cancelling your PO.

  • How it works Rescheduling as well Planning horizon

    dear Gurus,
    I have a situation quite strange :
    I have a Customer requirement with del date 03.11.2008 which refer a planned order firmed that has been moved at 12.09.2009, the MPS run create another planned order with reference to the customer requirement.
    Now I check the planning horizon as well as the rescheduling horizon and respevectly are 253 and 180.
    I would like to understand how the rescheduling horizon is managed and as well the planning too.
    Could somebody give me the some help?
    regards
    Gianluca

    Ok then it is fine.
    Planning horizon -
    Those materials that have undergone a change that is relevant to MRP within the planning horizon are included in the planning run. Such materials receive a net change planning indicator in the planning file.
    example if it is say 30 days, then the requirements whaich are with in 3 months from today will be considered for net qty calculation during MRP.
    Rescheduling horizon - The rescheduling period represents the period in which the system checks whether the existing dates of the receipt elements that are no longer allowed to be changed automatically still suit the requirements situation. If the dates of these elements are no longer suitable, the system creates the following messages depending on the requirements situation:
    Bring operation forward, if the date of the requirement lies before the date of the receipt element.
    Postpone operation, if the date of the requirement lies after the date of the receipt element.
    Reverse operation, if the requirement no longer exists.
    In reschduling check if you activate the check for firmed planned orders in OMDW, then it will get the rescheduling date after the MRP run so that you can make the changes.
    If you donot activate the check, then system will not consider the firmed planned order even if it is with in resheduling horizon and create a planned order.
    Now tell me what setting you have in OMDW.

  • MRP Type V1 - Does it create Exception Message for "Reschedule-in"?

    Hello Experts,
    We are using MRP Type V1 (Which has the Manual Re-Order Planning + External Requirements). However we are facing and issue with the Rescheduling part. Scenario is as following:
    Material ROP is - 5000
    Open Pur Ord is - 5000 (due in 01 June'09) based on the Std Lead time of the Material
    Stok on hand is - 0
    At this point a Sales Order is entered for 1000 pcs
    After MRP Run, we expect an Exception Message for the Purchase Order to have "Reschedule-in". But, instead, system creates a PReq for 1000 pcs and the required date is NOT the Sales Order required Date but based on the Std Lead Time of the Material.
    I have set the Material Lead time - 60 Days
    I have set the Reschedule horizon - 0 Days ( I even tried with different Days but NO use)
    However, when I change the MRP Type to PD, system generates a "Reschedule-in" Exception Message for the Purchase Order.
    How can I get the "Reschedule-in" Exception Message for the Purchase Order with the MRP Type V1?
    Thanks for your help in Advance!

    Anil,
    Reorder point/External MRP performs net requirements calculation (within replenishment lead time).  If the existing firmed supply elements minus the existing requirements bring the projected stock below ROP, it will propose an order that will bring the projected stock back to reorder point.  The proposal will generally come at replenishment lead time.
    In the normal business cycle, your sales order would confirm to lead time, and you now have a confirmed sales requirement at lead time, plus a new purchase req to bring the stock back to the reorder point.  The scenario you have described is working exactly as it is designed.  Consumption based MRP will not normally try to reschedule supply elements to match requirements inside of lead time.
    Rescheduling horizon generally is counted from the end of lead time.  It won't help you here.
    I guess if you insist on having a reschedule message, you could change your lead time to 0 days.  Not a wise move in my opinion.  You then have locked yourself in your choices of types of Sales order availability checks into one that ignores lead time.  You also have to find a way to let your buyers/planners know what the 'real' lead time is when they place their orders on the vendors.
    I don't know why you are using a consumption-based planning type (reorder point).  It sounds like your business requirements are that you actually need to be using a demand-type planning method (eg, your supply elements are driven by your demand, not by a reorder point/desired stock level).  If PD works the way you want, why aren't you using it?

  • Rescheduling dependency on plant or stor loc.

    Is the Rescheduling plant or storage location dependant ?
    So if we have stock in SE01 L010 but not in L001 will rescheduling , as it is configured for SE today , allocate stock that it thinks is available to orders ?

    Dear,
    Rescheduling-in is the exception message in the MD05 and MD04 transaction list. If you are maintaining rescheduling horizon in the customizing (transaction ) and enabled the check boxes for the firmed receipts to check for the rescheduling then system will carry rescheduling check within the scheudling horizon and display the exception message.
    Rescheduling check will be carried out against the requirements with the firmed reciepts within the horizon. For example if you have the requiremenst today for 100 pieces and there is firmed reeciept like prurchase order in the next month...and if this requirement and firmed receipt falls within this rescheduling horizon then there will be exception message will come for the purchase order to bring forward (or reschedule-in) to the date to cover the requirements.
    We define it in OPPQ /OPPR these are plant specific hope clear to you.

  • Firmed planned order creates a type of firmed horizon

    Hi Gurus,
    we had following system behavior the other day (actually a few months ago) that we weren't able to explain.
    It was beginning of November and a colleague of mine was creating his production schedule for the week before x-mas (i.e. another 7 weeks in the future). He was working at it and was called away for something and postponed the planning to another day in the week. The next morning he noticed that the MRP considered everything between today (must have been around the 5th of November) up until the 18th of December (the day he had firmed the planned order to) as a firmed horizon and didn't want to put any planned order inside.
    Even worse... all planned orders created by the MRP - now scheduled for after the 18th - had an exception message to schedule them in, as they came too late.
    Did anybody ever experience this behavior? If yes, please let me know, where I can manipulate this!
    Any help greatly appreciated!
    Thanks & regards,
    Bobby

    Hi Rupesh,
    first of all: thanks for joining!
    here are the answers to your questions:
    1.) lot-size = EX (i.e. not periodic)
    2.) no overlaps defined for EX in OMI4
    3.) no time fence and the rescheduling horizon is set to 100 days
    Looking at the rescheduling horizon and what is described in the OSS-note, I think I found it. The system actually works as designed. What we failed to do was to update the factory calendar with the downtime over x-mas back then. If we had done so, the demand would have been pulled forward, which means that the firmed order would have been consumed, instead the demand was distributed over the following for weeks.
    With the rescheduling horizon being so long, the system used the firmed order to cover all up-coming demands first using the firmed order before the MRP created other planned orders. It just happened that this one order was so big that it covered everything until then and that it looked like a "firm period".
    Thx for your help!
    Points will be awarded for pointing in the right direction...
    Regards,
    Bobby

  • Exception message 30 & Reschedule date

    Hi All,
    This is about the exception message 30 which is displayed in MD04 and the rescheduling date.How is this date determined and what does the exception message signify. how the system determines this dates?Also, what is the criteria for this rescheduling date to be displayed in MD04?
    For Ex
    Material XYZ , MRP Type : PD, Lot size :Monthly,PIR is 100 for march, After MRP run I am getting reqmnt date is on 1st April. Reschedule dt is 02-March, Expn Msg is 30. Inhouse production is 1 day & GR time is 2 days.
    Please let me know how system arrives on 2 march as rescheduled date & what does it mean?
    Thanks and regards,

    Dear,
    Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement.

The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement.

    The rescheduling horizon is always calculated from the MRP date.

  • Hi.Query on rescheduling proposal

    Hi.I have a doubt on "On what basis the system chooses the MRP Element which is proposed for 'reschedule in' whenever there is sudden requirement.

    Hi,
    Rescheduling horizon defines the period for bringing the receipts that should be
    taken into account for rescheduling.
    There are two process
    1.Reschedule in - Bringing the process forward Exception message 10
    1. Within the recheduling horizon the system checks whether after the
    requirement a firmend receipts exists which can be used to cover this
    requirement.
    2. Then the system displays the message Bring the process forward and
    exception message 10
    3. The net requirement calculation uses the receipt and the system will create
    new procurement proposal only if there is any shortage.
    4. For this we need to define a tolerance value for bringing the process in
    tcode OPPQ /OPPR
    The system checks compares this value with the difference between order
    finish date- Reqmts date.If this difference is more than the tolerance value
    the system issues the message for the MRP element to bring the process
    forward if the reqmts date lies before the firmed receipt element date.
    5. Same process for Postponing the process Exception message 15.
    During MRP the system carries out Rescheduling check automatically. No Tcode is reqd.
    Rescheduling check is to change the dates of already existing firmed receipts
    which were not planned on the same day as the requirements day to suit the
    requirement.

  • PPDS Horizon  is set 'Zero' ,Still PP heuristic is generating PP/DS Planned

    Dear All,
    We have a semifinished material for which SNP optimizer has generated SNP Planned orders for this component.
    User has deleted SNP planned orders from Planning book,and execute PP Heuristic inorder to generate PP/DS planned orders.
    PP/DS Horizon & SNP Horizon is defined as 'zero',the issue is why PP heuristic generating PP/DS Planned Orders up to 33 weeks.
    I have checked PPDS Horizon is mainatined as 'zero' in Product master (/n/sapapo/mat1) & in version management.
    My question is apart from this, Is there any other field from where 'PP/DS horizon' can be picked by PP heuristic.
    Thhanks with regards,
    Sajit

    Answer is no.
    Other then product master and version management no other place we can maintain the ppds Horizon.
    if you do not maintain any value any where then system will consider infinite PPDS Horizon.

  • PR is generating beyond planning horizon

    Hi All,
    We have an issue with MRP.
    MRP type-VB / V1
    Lot size-HB
    Planning Horizon-90
    Rescheduling Horizon-100
    Recorder pt=100
    Max stock level=150
    Stock =1130
    Requirement= 1300 (Requirement date for 300 quantities is on 01.12.2011)
    As requirement is too far still it is creating PR after MRP run, Can you please check?
    Not sure whether Planning Horizon will consider for V1 and VB also?
    Thanks,
    Suhas

    I guess that it only creates a PR with V1, not VB, right?
    I think that even with V1 it will not if you run MRP in "net change in planning horizon" mode.

  • Planning horizon and scheduling horizon

    hi gurus
    what is the difference beween planning horizon and scheduling horizon
    and how it will effect on production planning/MRP
    pls give me a detailed answer
    Faisal

    hi,
    planning horizon
    planning horizon specifies the period for the "Net change planning in the planning horizon".
    In this kind of net change planning, only those materials that have undergone a change that is relevant to MRP within the planning horizon are included in the planning run. Such materials receive a net change planning indicator in the planning file.
    The length of the planning horizon should include at least the following:
    the period in which sales orders are received
    the delivery periods
    the total lead times of the materials
    re-schedule horizon
    Define Rescheduling Horizon
    The rescheduling horizon is the period in which System checks whether the existing dates still suit the requirements situation for receipt elements that can no longer be automatically changed in the planning run. If the dates of a particular element are no longer suitable
    effect:
    If no rescheduling horizon has been maintained, the system will not carry out a rescheduling check.
    The system calculates the rescheduling horizon from the end of the replenishment lead time in reorder point planning.
