What is planning time fence

in material master we enter planning time fence & in house productiton & plnd delivery time
explain wirh a example

planning time fence: basically it is the period in which no changes to the plan happens automatically through MRP run
inhouse production time: the time required to produce a material in calender days
Pld delivery time: time required to procure a material if it is procured externally.
the latter 2 values are of significance in scheduling the delivery dates. inhouse production time for the product  and PDT for the components(sourced externally)

  • Scheduling Agreement & Planning Time Fence

    Hello,
    I read a lot of articles on Planning Time Fence and the MRP Types P1 to P4 that goes with it. And I have tested it out in a Testing Environment.
    But I can't get it to do what I need.
    This is a normal planning with no PTF and MRP Type PD.
    Sometimes we have false requirements that show up in the past due to human error. When this happens, MRP rolls during the night and adds a bunch of deliveries in the past to cover the requirement.
    I wanted to use the PTF to prevent this. Meaning that extra deliveries would get added by MRP but after a PTF and not Firm deliveries. So that once the error is corrected, MRP rolls again and deleted all the extra deliveries it added.
    ** Only P2 and P4 adds deliveries after the PTF, but I need it to act normal on a day to day basis aswell and have MRP create deliveries like the print screen above. To add non-Firm deliveries after the PTF is just in rare cases of human error.
    Not sure if my explanation is clear.

    Hi Patricia,
    The planning time fence is there to stop MRP from making changes to requirements that fall within the planning time fence.
    Your planning time fence is a rolling period which shifts by 1 day each day and is calculated as of the current date. Yesterdays date is passed so it would not make sense for a planning time fence to use a date in the past to start it's calculation.
    Everything that falls before the end of the planning time fence will not be changed by MRP and you will see that all these schedule lines in MD04 will have an * assigned meaning they are firmed for MRP.
    If you manually add schedule lines in the past, the planning time fence will not stop you from doing this. The planning time fence will only stop MRP from making changes.
    By the way:
    If you manually add requirements to the scheduling agreement then MRP will never change these requirements as these are fixed requirements.
    If your customer would add requirements in the past or you add independent requirements in the past and your current stock does not cover the requirements the system will generate schedule lines and will put these directly after the planning time fence with an exception message assigned to them.
    As a side note:
    I always wonder why such questions arrive in the forum as this is something that can be very easily tested in the test environment.

  • Planning Time Fence and Rescheduling Purchase Req

    How to Process the MD04 exception  u201C30 Plan Process According to Scheduleu201D for Purchase Req.
    Please provide me a Step by step procedure with example to Reschedule the Purchase Req with given rescheduling date.
    *Really I am confused with PLANNING TIME FENCE.
    What it does with Planned Order and Purchase Req ?
    Based on the some of threads in SDN, I couldnu2019t come to the conclusion of the terminology behind PTF.
    So could you please provide me an explanation with example will make clear idea on PTF.
    Thanks in Advance.

    dear friend,
    as far as i know, all planned orders that lie in the planning time fence are firmed. that means that they can no longer be changed automatically by the system in the planning run in long-term planning.
    outside the planning time fence, the system creates order proposals as usual according to the shortage quantity and the lot-sizing procedure. once these planned orders move into the planning time fence, they are automatically firmed depending on the how you have set the firming type.
    the planning time fence can be defined per material in the material master record or via the MRP group.

  • Planning time fence- MRP

    Hi Guys:
    Can I use Planning time fence if i am using MRP type PD?
    what are the settings i need to maintain for planning time fence and how it defined generally , is it a function of leadtime?
    Thanks
    Kodali

    Hi Padmasri :
    How to freeze the order proposals if i am using MRP Type PD.
    Because , I might run MRP Yesteraday it might have created Planned orders or Purchase requistions and Buyer might have issued purchase order to the vendor.
    today i got some more sales order and additional requirements , So when i run MRP today System propose Purchase requistions asking to change the previously created requistions on Previous Run?
    Could you explain how to manage this scenarious without timing fence and still using MRP type PD?
    Thanks

  • Firmed planning time fence

    Hi gurus,
    My business scenario is to firm my planning shop flloor during 60 days.
    To do it I used the planning Type P1. So If there is a requirement during these 60 days the planned orders is proposed at the end of this time fence. But this is the requirement date that is defined out the time fence. I have to begin the production (and so change the shop floor planning) during my firmed time fence of 60 days to respect the planning proposed by MRP.
    Is it possible to achieve my scenario ?
    Thanks.

    Hello Laurent,
    If I've well understood what you want :
    you would keep normal run of P1 for any planned orders which cover a requirement inside the planning time fence, and in the same time, you would get new proposals from the MRP in the planning time fence if the requirement date is outside the planning time fence.
    In this case, it seems me to be a bit difficult.
    The planning time fence is done to take in account the procurement proposal and not the requirement level. Basically, it's firmed the production plan in a defined horizon whatever the requirements could be.
    In anyway, we could imagine a specific program which runs after the MRP with these internal steps:
    . selection of the planned orders which have been rejected outside the planning fence,
    . filtering the selection against the requirement date (keep the date outside the planning time fence),
    . changing the start date of each good planned order and firming it ( & setting an opération code ).
    In my opinion, technically speaking, the bolt-on is very simple but the impacts on the MRP process has to be evaluate for the final users (understanding and maintenance). Moreover, there is the difficulty to determine the requirement origin in some context.
    I hope to be helpfull,
    With regards,

  • MD04 - Planning time fence for materials that are planned externally

    Hi,
    I have to develop a report in R/3 which will pick up values from MD04 (for a particular material/plant combination) and show the output in ALV grid of materials which are not planned in R/3 but APO.
    It should also show the planning time fence.
    For example, if i goto MD04 in R/3 and enter a material-plant combination which has MRP type X0 (external planning), it doesnt show me the planning time fence.
    This value/row has to be picked up from APO.
    Any idea how to go about it and what are the Function Modules I should use or is there any alternative for this ?
    Regards,
    Anand.

    Hello Anand,
    Try looking at user exit in MD04 that can change the values in MD04. Then, check for material-plant type of the order. If it is X0, call RFC to APO function module to read the information you want.
    I have develop before a report in R/3 that read the correct time of an order in APO to be displayed in R/3.

  • Firmimg the orders and planning time fence

    Hi, Pls explain about firming and non-firming and planning time fence while running mrp or mps?what is meant by firming the orders?  i do not know how it work and how can we interpret the reults? pls explain with one example.

    Firming: When an order is firmed , indicates that the Order  no longer needs to be planned in MRP.
                  Order gets firmed, when we change plannde order manually and save .
    Planning time fence: the time period during which if any Order comes it gets firmed subject the Compatible MRP type.
                                    Depedning on whether they need to be firmed or not and when a new requirement is creatd in the planning horizon, How the receipt needs to be planned within the Planning time fence or out side is controlled in the MRP type.

  • Planning horizon and planning time fence

    What is the meaning of terms
    - planning horizon.
    - planning time fence.
    Where and how we can use these terms?
    Kindly explain with a example.

    Hi,
    1. planning horizon
    Net change planning in the system only plans materials that have undergone a change that is relevant to the planning run within the period which you defined as the planning horizon. The system sets the net change planning horizon indicator automatically for these materials.
    In net change planning in the planning horizon, the system only plans those materials provided with the net change planning horizon indicator.
    2. planning time fence
    The planning time fence dictates a firm period for planning purposes. Subsequent MRP runs will not create planned orders within the time fence but will place them just outside it. Orders must be manually moved forward if desired. The idea is to create a short term period of plan stability.Check the MRP tabs on the Material Master for the planning time fence
    period for the material.

  • Planning time Fence and  Firmed Planned Orders

    Hi,
    Withing our 30 days planning time Fence, MD04 is showing * mark against the planned order, but when we drill inside the planned order, Firming indicator is missing.
    Using M1/ P1 MRP type.
    1) Is this a correct oservation?
    2) How does it affect the availability check, if we are considering Firmed Planned order to be included in the Av Chk. Will this planned order be considered with the Availability check?
    Thnx!
    Abhi.

    Dear,
    Let us understand with an example
    MRP type = P1
    Time fence = 30 days
    Let say you have created 3 requirements
    01.12.2007 - 100 TO
    01.01.2008 - 100 TO
    01.02.2008 - 100 TO
    Let me know what are you expecting the syatme to do if you run MRP  today?

  • Planning time fence and Lot size

    Hi,
    MRP type=P3, Planning time fence=28 days, lot sizs=EX and all 28 days are working days.
    so today =05/112009 and i check the MD04 End of planning time fence is 03/12/2009
    But when i change the lot size to =ZC(3 Months lot size) keeping the rest all same as above.
    and when i check MD04 The planning time fence moved to 01/01/2010
    What should be done to keep the planning time fence as 03/12/2009 and i don not want to change either MRP Type or lot size

    Praveen,
    I think your Lotsize Indicator is based on Planning Calendar. Please check the period definations of the planning calendar assigned to the material in the MRP2 view.

  • Firming logic of planning time fence

    Hello PP experts,
    I have a question about the firmming logic of planning time fence, based on the test of mine, the firmming date will consider the available date.
    For an example, GR processing time = 10 days, MRP type = P1, planning time fence = 5 dyas, today is Mar.10, and after the MRP run, if a schedule line GR date is Mar. 12, but the AV date is on Mar.22, then this schedule line will not be firmed, cause it considers the AV date.
    So my question is , can I firm the schedule line according to the GR date but not AV?
    Further more, why I use the GR processing time, because it can distingush the delivery date and the arriving date, since this purchasing part is an Ex-work part. Our user wants to know what is the date user pick-up the goods from the port. Useing GR processing time can display the pick-up date. Even though the GR time is a plant internal disposing time. So if anyone has a good idea that where can I put the transportation time in order to let the MRP run can consider the time difference, that will be better.

    For the planning run, the firming type determines how procurement proposals are firmed and scheduled within the planning time fence. There are the following firming types:
    Hi,
    It depends on the MRP type selected. and the Firming type maintained in the MRP type.
    If the Firming type is
    0
    Procurement proposals are not firmed automatically. No firming takes place with this firming type.
    1
    Procurement proposals within the planning time fence are firmed automatically as soon as their date is at least one day before the end date of the planning time fence. The date of new procurement proposals created in the planning time fence is moved to the end date of the planning time fence. As a result, these new procurement proposals are not firmed.
    2
    Procurement proposals within the planning time fence are firmed automatically as soon as their date is at least one day before the end date of the planning time fence. No new procurement proposals are created automatically within the planning time fence; that is, the shortage situation is not adjusted within the planning time fence.
    3
    Procurement proposals within the planning time fence are not firmed automatically. All procurement proposals required to cover the requirements are moved to the end of the planning time fence.
    4
    No procurement proposals are created automatically within the planning time fence; that is, the shortage situation is not adjusted within the planning time fence.
    Hope it is clear

  • What is planning time fense in simple words?

    what is planning time fense and demand time fense?

    Hi
           This concept is used for master production schedule items . Which are A class and any planning change for these components might affect company adversely .
    Now this is provision to lock or restrict the plan from changing .
    Depending upon your setting in material master m1, m2 , m3 etc and planning time fence it will firm the planning proposal and any new requirement will be shifted at the end of the planning time fence .
    In MD04 you can see the proposals created and shifted at the end of planning time fence . ( depending on your settings )
    IN Simple words it is time within which no automatic changes will be made and your MPS planned will be saved .
    If satisfied , please reward and close .

  • Diff. bet PLANNING TIME FENCE & PLANNING HORIZON

    Hi all,
    whats the diffrence between , planning time fence & planning horizon ?? where it use ???

    time fence - like a fence beyond with in which some changes are not entertained.
    horizon- will tell the system not to consider some requirement if the requirement date lies outside the horizon.
    Horizon is defined at plant/mrpgroup/mrparea level
    Time fence is defined at material level.
    Fence is usually used in MPS scenario where in some special very important materials are considered and any changes may affect the company profit.
    with time fence- i can make the system not to consider the change with in the fence, with horizon system considers the change with in horizon, not outside.
    I hope now you are clear about the application of it.

  • Capacity levelling Auto release at planning time fence

    Is it possible to have a background report run which will convert process orders to released process orders when they reach the planning time fence?  I can set planned orders to release when converted to process orders automatically but this is not what i want as it removes any flexibility in CM29 plans.  I don't know how to set this up and was wondering if anyone could give me some advice on how i could do this.  Thanks.

    Hi Sam,
    to do what you ask, you need a custom report (Z).
    I do not know standard report that do this.

  • Managing planning time fence ( P1 MRP type ) and firm zone in ME32L

    Hello,
    I want to know if there is or are some documents to know how to manage planning time fence in MM02 and firm zone in ME32L ?
    For me, in ME32L the firm zone is the firmed quantities sent to suppliers but not firmed for MRP so how to manage this easily ?
    Thanks.
    Romeo.

    Dear,
    Firm ZOne in SA, says that that much qty will be procured from that vendor with in that date specified, if not taken the production cost and cost related to that will be paid.
    Now the planing time fence, is the time with in which no change is allowed. Hence if there is any new requirement to that RM, then it will be pushed to outside the time fence.
    Hence if there is a schedule line which is already there and requirement is coved with in that, then your requirement is met, if not system will create a new schedule line in the trade off zone/planning zone.
    I hope you got the point.
