Planning horizons of SNP and PP/DS

In didn't understand the  below terminolgy , can anyone please explain the meaning of it in detail..
The planning horizons of SNP andPP/DS overlap , if the SNP  production horizon is shorter than the PP/DS horizon

Please see the following two forum threads
SNP and PPDS planning horizons
Difference between Plannnig Horizon and Production Horizon
Also refer to SAP Note 481906 - SNP - PP/DS integration for more details (its a pretty lengthy note)
Hope this helps.

  • SNP and PPDS planning horizons

    Hai,
            I am reading through SNP and PP/DS planning horizons. I understand that SNP doesnot plan anything within SNP production horizon whereas PP/DS plans only within the PP/DS horizon.
    Now, I get confused when trying to understand the following sentences:
    1. If production horizon of SNP is smaller than the PP/DS horizon, the planning horizons of SNP and PP/DS overlap with each other. In this horizon, SNP determines the receipts with most cost-effective sources of supply and lot sizes and PP/DS plans the receipts in more detail.
    2. If requirements within the SNP production horizon cannot be covered by PP/DS, then SNP plans the receipt outside the SNP production horizon(this corresponds to the logic in the PP/DS planning time fence in short term planning).
    3. If the PP/DS horizon in the product master is set to be greater than SNP production horizon, this gives rise to an overlapping area in both SNP and PP/DS receipts are created.
    Can anyone please help me undestand the above? An example or somedocumentation reference is appreciated.
    Thank you.

    Hi Visu,
    Good question. You missed Planning Time Fence in the equation.
    |--||--
    >
    1.       PTF             SNP            PPDS
    You execute PPDS Heuristic (Product Heuristic) then requirements upto PPDS horizon will be covered by receipt elements (beyond Planning Time Fence). If you run SNP Heuristic then receipt elements will be created from SNP Horizon out in future deleting the receipt elements created by the previous PPDS run. But note that while PPDS planning is down to the second level SNP planning is minimum at a day level. If you have weekly buckets then all requirements for one week will be clubbed and single receipt element will get created. However you can consider SNP orders as fixed during PPDS Net Requirement Calculation through appropriate development.

    2. This is also not clear to me as I cannot build the scenario as described. The above diagram is the closest I could come up with. But in this case if you run SNP Heuristic and there are unmet requirements (sitting between PPDS and SNP horizon) then the receipt for that will be created only at the start of the SNP Horizon.
    3. This is correct but already explained in 1.
    Hope this clarifies or at least does not add to the confusion. BTW if you are interested then please read OSS Note 481906 - SNP - PP/DS integration (documentation).

  • Does Make To Order planning consider any SNP/PPDS Horizons

    Guys
    Does Make To Order planning consider any SNP/PPDS Horizons unike the Make to Stock scenario planning?
    Thanks

    Thanks for the response guys.
    In RRP3 view, when I look at the Individual project segment demand, I do not see any  SNP/PPDS Horizons. However, when I see the demands under the MTS segment, I can see the  SNP/PPDS Horizons.
    In MTS scenario, I understand that only those orders that falls within PPDS horizon are picked up by PPDS planning and orders outisde SNP horizon are picked up by SNP planning.
    However, as MTO is purely PPDS planning, I am just wondering whether  SNP or PPDS horizon comes into the picture in this scenario or not.
    Further more, my primary concern in MTO scenario is, if PPDS horizon is taken into the picture ( which is usually in the near visible term and < SNP horizon, say 15 days), and as PPDS planning doesn't pick the demand in the MTO segment until the demand falls with in this horizon, aren't we not leveraging the full functionality of procurement planning, as PPDS plans the demand by picking it just before 15 days (in this example) of the original requirement date, and the company might not be able to fulfil the customer order as the replenishment time might be long for this particular product being procured/produced.
    So, I am basically leaning towards an understanding that what ever demand that falls in the Individual Customer/Project segment (MTO), it will be picked up PPDS planning regard less of SNP/PPDS horizons.
    Please advice, if my understanding is wrong and I would appreciate if you quote some examples which might help me better understand the scenario.
    Thanks

  • SNP and PPDs horizons

    Hi,
        If I have SNP horizon of 0 days and PPDs horizon of 0 days. Then does the system plan twice and I see double the quantities because both SNP and PPDS are planning the same time? I mean does it create both SNP and PPDS planned orders doubling the planned qty.?
    Thanks.
    Edited by: Visu Venkat on Jul 30, 2008 3:14 PM

    Typically if both these horizons are zero in the Location Product, the system is supposed to check the PPDS horizon kept in /n/sapapo/mvm transaction. Usually its a best practice to have a non-zero value in the version level. under the situation where even PPDS horizon at version level is 0, I would expect PPDS orders not be created at all by any systemic process. (different PPDS heuristics work differently though) However it should be possible to create PPDS orders manually outside of the PPDS horizon. Usually SNP orders are deleted and PPDS orders created in its place by the PPDS solver as soon as those orders are inside the PPDS horizon. I would be surprised by what you are observing though.

  • SNP and PPDS Horizon

    Hi All,
    Can anyone please let mw know what exactly is the difference between SNP and PPDS Horizon ??
    How is it identified. .
    What are the applications of using these horizons . .
    Thanks in Advance,
    Prasad.

    SNP Horizon: Time segment, during which SAP APO Supply Network Planning (SNP) does not plan production. This means that SNP does not create any planned orders in it but shifts production to the first day after the end of the production horizon.
    PPDS Horizon: Time segment in which Production Planning and Detailed Scheduling (PP/DS) can automatically create, change, or delete receipts. The duration of the horizon begins on the current date and continues for this number of calendar days into the future.

  • Getting an error while activating a planning area "Enter values for planning horizon From and planning horizon To for the storage time profile level"

    Dear S&OP community,
    I am getting following error while creating a planning ares in a newly installed sandbox. "Enter values for planning horizon From and planning horizon To for the storage time profile level".
    This what I did...
    1) Created new attributes and master data objects and activated them successfully.
    2) Time profile created and activated successfully
    3) Trying to create planing area by assigning  time profile in step 2 and assigned master data from step1..Unable to save the data and system returns 
    this error - "Enter values for planning horizon From and planning horizon To for the storage time profile level"
    My understanding is time profile needs to be active  but doesn't have to have values...
    Any help is appreciated.
    Thanks,

  • 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 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.

  • Planning horizon and scheduling agreements

    We have a planning horizon that goes out 1 year.  However MRP stock requirements is showing planned orders for scheduling agreements that go out beyond the planning horizon.
    Is there a reason MRP sees these MRP elements with dates well beyond the planning horizon of 1 year?

    Hi,
    In MRP we can run the MRP with Planning run Type  With indicator
    NETCH(Net change planning) and NETPL(Net change planning in the Planning Horizon)
    Planning Run Type in the Initial Screen
    Use
    You use the planning run type (Processing key indicator in the initial screen of the planning run) to determine which materials are to be planned.
    Features
    There are three different planning run types:
    During regenerative planning, all materials are planned for a plant. This makes sense when you are carrying out the planning run for the first time as well as later during production if data consistency cannot be guaranteed due to technical error.
    The disadvantage of regenerative planning is the fact that the system has to deal with high capacity loads because all materials are planned, including materials, which may not be affected by the planning run.
    To overcome this disadvantage, it makes sense during production to carry out the planning run using the net change planning procedure. The only materials that are included in the planning run are those, which have undergone a change relevant to MRP since the last planning run, for example, because of warehouse issues or sales orders, changes to the BOM and so on.
    The net change planning procedure makes it possible for you to execute the planning run in short intervals, for example, in daily intervals. You can thus always work with the most up-to-date planning result.
    You can use net change planning in the planning horizon to shorten the MRP planning run even further. The system then only plans materials that have undergone a change relevant to MRP within the planning horizon. In order to also plan changes outside of the planning horizon, you must execute the net change planning run in greater time intervals.
    You define the planning horizon per plant or per MRP group in Customizing for MRP in the IMG activity Define planning horizon. The planning horizon should be at least long enough to cover the period when sales orders are received. It must also accommodate delivery periods and the total lead times of the materials.
    In single-item planning, you can only choose between net change planning and net change planning in the planning horizon. Regenerative planning is not useful, because the material has already been defined and does not have to be determined after the evaluation of the planning file.
    The system automatically flags the materials that have undergone a change relevant to MRP with a corresponding planning file entry in the planning file (see also  Checking the Planning File and  Planning Run Type).

  • What is business logic of selecting stock transfer horizon in snp

    Hi Team,
    what is business criteria of selecting stock transfer horizon in snp.
    What are the parameter we need to take into account to select stock transfer horizon?
    Regards,
    Sunil Patil

    Hi,
    Yes,Stock is not planned during this period.
    But what is business criteria of selecting stock transfer horizon in snp? Client intially do not what is stock transfer horizon and why they have to used and how much days of horizon is required.
    When this kind of situation arises so that they use this stock transfer horizon.

  • SNP and R3

    Hi, all guru
    I'm new to SNP, would like to clarify the process flow .
    What is the output of each SNP process after release the forecast from DP to SNP
    1. is the first process is DRP ? when we run optimizer, what is the output , any order send to R3
    2. how about Deployment and TLB run , any output , any order type created ? any data sent to R3
    3. when R/3 received those data , what R/3 do with it .
    4 what is the flow between SNP and MM/PP at R3
    5. what is Rough cut capacity planning , it is seperate data being load to SNP, how to relate to SNP process
    it will be very helpful if we can have a scenario base of example
    many thanks

    Hi :
    following are the steps :
    Once the demand plan is released form DP to SNP , Planned Independent Requirements are created for SNP / PPDS.
    Now performing SNP Runs through Heuristics , CTM or  Optimizer Results in Distribution & Production Plan for
    Medium to long term horizon . After SNP run you can generate alerts for any exception and resolve them .
    SNP plan now consist of Transaction data (Purchase requisition , SNP Stock transfer order or SNP Planned order)  . If you are using PPDS , SNP orders can be converted to PPDS orders which are more detailed .
    After production planning is complete , Deployment confirms stock transfer order based on current receipts and  demand .
    TLB runs groups together stock transfer orders into  shipments .
    All these transaction data is passed to R/3 through CIF .
    SNP planning is rough cut only if you are utilizing SNP PPM which only contains critical resources and material .

  • Difference between SNP and PPDS.

    Hi all,
    i want to know the functional diff betwn Snp and PPDS. .
    i mean what activities come under Snp, after what activities it is under PPDS. . .
    Any info on the same will be highly appreciated.
    Regards,
    Prasad.

    Hi Prasad,
    SNP basically does rough cut capacity planning on a constrained or unconstraint situation whereas PPDS does time continous finite capacity based on constraint or unconstaint situation.
    SNP & PPDS works on horizons.  There are scenarios were SNP horizon can overlap with PPDS horizon. 
    SNP uses SNP PPM as master data whereas PPDS PPM as master data.  The output are SNP orders and PPDS orders. 
    The minimum day for SNP planning is 1 day whereas PPDS can go upto even 1 sec(ie microscopic planning)
    Starting from a demand plan, Supply Network Planning determines a permissible short- to medium-term plan for fulfilling the estimated sales volumes. This plan covers both the quantities that must be transported between two locations (for example, distribution center to customer or production plant to distribution center), and the quantities to be produced and procured. When making a recommendation, Supply Network Planning compares all logistical activities to the available capacity
    We use the Production Planning and Detailed Scheduling (PP/DS) component
    a) To create procurement proposals for in-house production or external procurement to cover product requirements
    b)  To optimize and plan the resource schedule and the order dates/times in detail

  • BADI for planning PRT with SNP

    Dear Experts ,
    I am facing some problems with PRT planning .
    I need to send to SNP suboperation from main operation that is using PRT.
    How do I plan PRT with SNP PDS ?
    How the standard  PRT works with SNP?
    For PPDS i am using BADI CUSLNTRTO_ADDIN .... is there any specific BADI for SNP ?
    Hope some one can help me ....
    Nice Regards
    Mauricio

    I believe, 10 days are because of stock transfer horizon.
    I am just guessing over here, in case of Heuristics, you must be planning finished product only.
    While CTM plans for entire supply chain. CTM may not have found supply available for semi finished product and is trying to procure it. Hence, distribution receipt is getting created after Stock transfer horizon.

  • Min max lot size time based for use with SNP and PPDS

    Hi all, Is there anyway to set up time based min and max lot sizes? ie we want to have a Max lot size which is small for use with the first 3 months of our plan which starts life in SNP and then converts to PPDS and into blocks for block planning, but months 4 to 36 we want to leave as large max lot sizes as there is no need to have the small max lot sizes for the different horizon.
    As far as I can see there is only a material/plant lot size  and Max lot size and no way to have a different setting in a different time period.
    Thanks
    j

    Hi John,
    As you know, in the product master, the lot size maintenance is time-independent, so that obviously can not be used for your scenario. As per my understanding, to meet this using standard functionality, you can maintain multiple product specific t-lanes (for STRs) and PDSs (planned orders) with required lot size ranges and validity dates (for short or long term horizon). But, again since the validity of t-lanes and PDSs will not be automatically rolling forward so the updating the validities will be a challenge.
    The other option could be to enhance the heuristic functionality at lot size selection step while creating order.
