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 .

  • Releasing a portion of Forecast for SAME product to SNP and a portion to R3

    After running  DP forecasting, can a portion of the forecast for the SAME product be released to SNP and a portion transferred to R3 ?
    The requirement here is for a product, say Prod1, demand comes from 2 Business lines. Through Project System u2013 PS module, system differentiated the business lines
    From a DP phase 1 perspective, client want to do global forecasting for 2 business lines
    The challenge we r facing is demand coming from Business line 2 cannot be consumed in SNP as demand comes in the form of Automatic Reservations and CIF doesnt have the capability to CIF automatic reservations. Standard CIF only cifs manual reservations. So client wants the forecast for Business line 2 (Note that this is for the same product) to be transferred to R3.
    So can a portion of the forecast for the SAME product be released to SNP and a portion transferred to R3 ?
    TIA

    Hi Visu, thanks for the reply
    So if If I want to release the demand plan as a background job to both R/3 and SNP based on certain characteristic(Business Line), I  am thinking of doing the below things.
    Release to R3 -- >
    1. Create a Transfer Profile
    2 . Create an Activity using "MC8T- Define Activities for Mass Processing" and assign this transfer profile to the activity.
    3. Create a Planning Job by selecting a Selection ID( that has the demand separation characteristic)
    4. Schedule the Planning Job
    Release to SNP -- >
    1. Create a Release Profile
    2 . Create an Activity using "MC8T- Define Activities for Mass Processing" and assign this Release profile to the activity.
    3. Create a Planning Job by selecting a Selection ID( that has the demand separation characteristic)
    4. Schedule the Planning Job
    However, I am not sur eif I can do the follwoing.
    1. Can I create a SINGLE Planning job to release demand BOTH to R3 and SNP ?
    2. If I am using Different Key Figures in the planning area( per business line), do I have the need to maintain a separate characteristic value in the POS, as anyway I can load the data from cube to these separate key figures based on business line ?
    3. MOST IMPORTANTLY, if I use different planning jobs to release to R3 and SNP, I can have different selection ID's ( per business line) and select these in the planning job instead of maintaing TWO DIFFERENT Key figures. do you think this is feasible ? Any thoughts/advice ?
    TIA

  • 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.
    |--||--
    >
           PTF              PPDS           SNP
    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).

    do i need to have sales bom for SNP PDS  is it mandatory ,
    or just normal production bom is enough for having both snp and ppds Product data structure
    Thanks & Regards

    Dear Satya,
    Thanks for your reply
    I know PV is needed for SNP PDS , is the PV which is used for SNP PDS is same for PDS PP/DS, or we need to use and special key during CIF ing to APO from ECC 6

  • Fetch SNP and PPDS orders

    hi,
    I am new to APO. How to get PPDS and SNP planned orders from livecache.
    Regards
    Dhanu

    1)     I am able to get all SNP and PPDS order using BAPI called BAPI_PPDSSRVAPS_GET_IO_NODES from Live cache. This BAPI fetching order id as key field.
    2)     I need to fetch the data from DMCP table using this order id but there is no link with this order id with DMCP table.
    3)     There is a field called GUID in DMCP table. I used one FM to convert order ids to GUIDs to get the data from DMCP table. All order ids got converted into GUID.
    4)     Till here everything is good.
    5)     But when I am trying to pull the data from DMCP table based on GUID, it is pulling only SNP orders not PP/DS orders.
    6)     I have tried so many ways but I am getting SNP orders only.
    7) I need SNP and PPDS orders
    Can you help me on this?

  • 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.

  • 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

  • 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.

  • Difference between Release DP to SNP and Release profile

    Hi Experts,
    What is the difference between Release DP to SNP
    And maintain Release profile. Can u suggest am lot of confusion about these?
    Explain in brief. 
    prasad

    Hi Prasad,
    Aparna point is absolutely correct. From usage point of view, date is the only difference.
    There are 2 options to release forecast from DP to SNP.
    1. Demand Planning -> Planning  -> Release -> Release to Supply Network Planning.
    2. By creating Rlease profile, activity , planning job, etc
    1 is used for online purpose & for few product/location combinations. However 2 is used for the mass processing.
    Use 1 to release a limited amount of data (a few product / location combinations only) from Demand Planning to Supply Network Planning. Do not use it for mass releases, for example large planning books.
    If you try to release too much data with this transaction, memory problems are likely, since the system tries to read all the data
    simultaneously. For mass processing, use 2 - Releasing the Demand Plan with Mass Processing.
    Decision is based on data volume & performance.
    Hope this helps.

  • 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.

    Umesh
