Target Days Supply in SNP Heuristics and Deployment

Dear Experts,
Does the Target Days supply only define the minimum and not the maximum stock levels?
Example: consider a Period P1
The target dayu2019s supply is 20 days, and the Days Supply in Period P1 is more than 20 (suppose 35)
The Total Demand in that week is not big enough to bring the Days supply < 20
Question:
Does the system still create a Distribution Reciept (Planned) in this case and keeps increasing the day's supply of dest location? Or does it create stock transfers only if Days Supply is threatening to fall below the Target Days Supply?
In other words:
Does Target Days Supply only come into picture when Days Supply < Target Days Supply, in which case the system adds the difference (Target Stock Level u2013 Current Stock Level) to total demand while creating stock transfers.
When Days Supply is >> Target Days Supply, does the SNP Heuristic still create a Stock Transfer even though there is enough stock to cater to the current total demand and not fall below Target Stock?
Hope you can help in understanding this concept.
Regards,
Rimjhim

Thanks for your reply.
Please correct if I have misunderstood:
While calculating the net requirement during SNP Heuristic run, the system will apply Target Stock Level into consideration and will only create a Pur Req if the stock is falling below the Target stock.

Rimjhim

  • Targets days supply

    Hi Gurus,
    Please let me know on targets days supply in PP DS and the effect of it on planning. what are the necessary settings to be maintained for achieving the same ?
    Thanks,
    Prasanth

    Hi Prasanth,
    In APO the requirements is rolling that is if you have Forecasting then the forecast for a month it is
    disaggregated into days or weeks hence if you plan to have a safety stock planning done by APO this method
    of maintaining Target days helps to maintain the stocks at the location all the time so if you define 4 days
    as the Target days of supply then at all time Heuristics run or optimizer run will ensure that stocks are
    there to meet the requirement of next 4 days as is in your case. In case of shortfall system will generate
    a requirement on the Source plant based on the transportation lane.
    Settings are maintained in Product Master under Lot size tab (Quantity and date Determination).
    Please let me know if you need any further information on this
    Thanks,

  • Difference between SNP Heuristics and PP/DS Heuristics

    Dear Friends,
    I have a basic question regarding Heuristics , is SNP Heuristics and PP/DS Heuristics are same
    if not what is the key difference between them
    i am very clear about PP/DS heuristics but not sure how heuristics is used for planning in SNP , i am able to read sap help , but could not able to get clear answer
    Please help
    Thanks & Regards
    Raj

    Hi Raj,
    Heuristics is the simple algorithm which can be attached to any working
    module to perform our business requirements.
    PPDS Heuristics is used to create procurement proposals for uncovered product requirements
    and to carry out planning tasks for products or orders. 
    This will be used during Production planning run and in interactive planning.
    whereas
    SNP heuristic is used during capacity levelling and deployment.  The SNP Heuristic performs
    requirements planning through the entire supply chain network to determine how to satisfy
    the customer and/or consumer demand.
    SNP heuristic, based on a repair-based planning approach, efficiently plans complex distribution
    networks in multi-site production environments.

  • Differece between SNP Optimizer and Deployment Optimizer

    Hi,
    Can anyone please list down the difference in the planning method for a deployment optimizer and SNP Optimizer?
    Thanks & Regards,
    Sanjog Mishrikotkar

    Hi Sanjog,
    First of all if we understand the difference between SNP Heuristic Planning run which finds the 'Source' of Supply with dates and quantities and Deployment Planning run which CONFIRMs the Supply .... then it is easy to understand the difference between SNP & Deployment Optimizer.
    The Optimizer as you know Optimizes based on Costs and Objectively tries to MINIMIZE it.  Therefore while the SNP Optimizer finds the most cost effective way of finding the Source of Supply with dates and quantities, identifying where in SC it is better to Store or move the Product,  while the Deployment Optimizer generates the Best way to CONFIRM whether the Supply can ACTUALLY be done for the next few days.  Deployment precedes the TLB Run which after confirmation we put the Quantities on a Transport Load to build Orders for Execution (Shipping).
    Both are Cost based & use the Same Costs Information ... however one Plans and the Other Confirms.  During Deployment Optimization run, the Optimizer may decide to confirm the supply from a different source than what the SNP Optimizer planned based on the Available to Deploy Stock Quanties and the Cost of Confirming the Supply.  The Deployment Optimizer will apply Fairshare & Push/Pull Rules and looks at the Push and Pull Deployment Horizons which SNP Optimizer cannot.  The Difference is also in Planning Time Range.  You plan SNP Supply for mid to long term time range.  The Deployment looks at Confirming the supply in the next few days from TODAY. 
    So in short first understand the Difference between a SNP Heuristic and Deployment Heuristic and apply the same principle to a cost based optimization. This should tell you the difference between the two.
    Try read this ...  First para on Deployment Optimizer ...

  • SNP heuristics and optimiser using transport lane validity dates

    I am using APO SNP 5.1.
    In particular I am trying to use the SNP heuristics and optimiser for supply planning.
    Can anyone confirm whether transport lane validity dates are respected by (a) SNP heuristics and (b) SNP optimiser, ie no transport requisitions will be created during times when the transport lane is not 'open' in terms of validity dates.
    Thanks for any advice on this...

    Hi,
    Irrespective of the SNP planning engine you are using, a t-lane will only be considered if the t-lane is active as per the validity dates.

  • How to calculated "Target days' supply" in SOP Planning

    Hello all
    after input "Target days' supply" in SOP. then run "Create Product Plan"
    there will create production plan in screen. thus i used "Target days' supply" strategy.
    there have one quesion, how to calculated product quantity?
    Thanks.

    Dear,
    System calculate days supply automaticly, this that no of days required to maintain that stock level,
    In the standard planning table, choose Edit-Create production plan-and the desired strategy (either Synchronous to sales, Zero stock level, Target stock level, Target daysu2019 supply, or Plan externally).

  • Runtime for heuristics and Deployment

    Hello All,
              When I execute the Heuristics or Deployment (SCM 7.0) even for a single product it takes around 15 minutes.
    So let me know how to improve the run time.
    Or do we need to install any support packages?
    Thanks,
    Siva.

    Hi Siva,
    Check the following
    1) Any master data error in the location product planned (MRP views, resource used, PPM, lane, material master etc.,)
    2) Check the job log in sm37, if no log created, delete the job and rerun again
    3) Check inbound and outbound queues
    4) Check the application log if any errors displayed
    5) Run CCR for the location product for all transactional data and then run heuristic
    Confirm your observations.

  • Material Master: where to maintain "SNP Demand" and "Deployment Profile" ?

    Hello experts,
    the APO material master has on tab "SNP 2" the section "SNP Demand Profile" and "SNP Deployment Profile". For my understanding such profiles allow you to assign the same settings to a lot of products simply using such profile which contain predefined settings.
    Does somebody know where / how I maintain (change, create, delete) such profiles. I was scanning master data and SNP section within customizing SPRO and the within APO application menu tree  under SNP and master data ... but couldn't find it.

    /n/sapapo/snp102  - Supply
    /n/sapapo/snp111 - Deployment

  • Safety days supply not followed due to change in Means of Transport in SNP

    Hello All,
    I am facing a strange issue regarding the SNP heuristics and means of transport. We observed that the system was not respecting the safety days supply. For example if we had a receipt in bucket 'N' and there is a violation of safety days supply in bucket 'N-1'. When we un a heuristic ideally system should delete the receipt in bucket 'N' and create a new one in bucket 'N-1'.
    But we observed that the system is retaining the existing receipt in bucket 'N' and also creating a new one in bucket 'N-1'. This is making the available days supply to increase manyfolds and the whole plan looks inconsistent from Safety Days point of view.
    After analyzing the issue i observed that if we have existing receipts using a Means of Transport 'X'. Now if we run the heuristic using a Means of Transport 'Y' then the system doesnt touch the existing receipts. If I run teh heuristics using the existing Mean of Transport then it works absolutely fine.
    Kindly suggest.
    Regards,
    Abhi

    Hi,
    when you check all products flag it means the means of transport is available for all products and not product specific, to select the MOT for SNP you need to check the aggrgtd plng flag.
    Also safety stock has nothing to do with MOT, SNP heuristic plans based on checks the quota arrangement if its for multiple MOT it will distribute the PR based on the ratio in quota if both MOT are able to meet demand on time, otherwise it will violate quota till the time both MOT are not capable of meeting the demand on time.
    If no quota is defined it will check for which lane is able to meet on time n if their are multiple lanes which can fulfill demand on time then it will choose MOT with less cost.
    Have you got multiple MOT for a source destination combination to be considered for SNP heuristic?
    Just check your design again and explain the problem again as this is not the standard expected behavior.
    Thanks,

  • SNP Heuristics- TSL parameter

    hello Gurus,
    I am using target stock level method 1 in product master;this setting works fine in interactive planning but not in back ground planning run.
    Can you please throw some light on significance of the below attribute and where/how to set this attribute
    Indicator for Selecting the SDT Profile from /SAPAPO/SCZPRF
    Use
    The selection you make here determines how the target stock level is calculated.
    You have the following options to calculate the target stock level:
    (0) Use the safety stock and target days' supply on the Product master.
    (1) Use target days' supply and safety stock only for the time period covered by the Time buckets profile.
    (2) Use target stock level specified in the Planning parameters only for the time period covered by the time buckets profile.
    (3) Use target days' supply and safety stock specified in the Planning parameters and apply the last target stock level value found in the past to additional periods that fall beyond the period defined in the Time buckets profile.
    (4) Use the target stock level specified in the Planning parameters and apply the last target stock level value found in the past to additional periods that fall beyond the period defined in the Time buckets profile.
    SAP recommends that you choose option (0) initially. For simulation purposes, you can change this setting by choosing, from supply network interactive planning, Planning -> Set Planning Parameters. After you have you have had an opportunity to run supply network planning in interactive planning mode using the different settings for simulation purposes, you can change this setting in the product master to make it valid for all supply network planning runs.
    Dependencies
    You must define options (1) to (4) in supply network interactive planning (Planning -> Set Planning Parameters) before you select an option in the product master data.

    Ha ha, I like this. New challenge!
    What about this scenarios.
    1. Forecast 500.000 unit per month. Lot size procedure Lot-for-Lot. Run SNP heuristic with time bucket month. Result - 1 SNP Pl.Order = 500.000 unit per month
    2. Forecast not important. Lot size procedure Fixed Lot size = 500.000 (or min/max lot size). Run SNP Heuristic with time bucket month. Result - 1 SNP PL.Order = 500.000 per month.
    You can have a separate job (separate selection loc/prod) for these SKUs with time bucket months (this is in the case when you are working with time bucket weeks).
    3. At transportation lane level. Create transport capacity resource and assign it to the t.lane. In the resource you have the possibility to restrict the capacity at 500.unit per time bucket month.
    Me too I have some issue at PPDS level. Can you give me some ideas for this issue http://scn.sap.com/thread/3596884

  • Target Days of Supply

    Hi,
    Is there any method in APO of smoothing out a
    supply plan similar to the range of coverage profile in R/3.
    What we would like is that:
    APO looks out say 100 days in the future.
    Adds all demand.
    Divides by 100 to get an average daily demand.
    Creates a supply plan based on this average.
    Thanks,
    L

    Hi Liam.
    I believe that you could acheive this in SNP with the use of macros manipulating the target stock level key figure.
    You could include a TS key figure to capture average daily demand and include it how you require in the calculation of the target stock level.
    Under normal conditions, Heuristic run aims to reach the target stock level in each bucket.
    Haven't tried it, but would suggest caution when moving away from standard SNP macros and lots and lots of testing.
    Hope this helps.

  • PPDS and SNP Heuristics

    Hi All,
    can anyone please let me know, what exactly is the difference between SNP and PPDS Heu. ???
    Thanks in advance,
    Prasad.

    Hi Prasad,
    1) SNP heuristic:-
    The heuristic is used as part of a repair-based planning process consisting of the heuristic, capacity leveling, and deployment. The heuristic run processes each planning location sequentially and determines sourcing requirements. The heuristic processing groups all demands for a given product at a location into one demand for the bucket. The heuristic run determines valid sources of supply and corresponding quantity based on pre-defined percentages for each source of supply (quota arrangements), or procurement priorities for transportation lanes and production process models (PPMs) or production data structures (PDS). The demands are then passed through the supply chain to calculate a plan. However, this plan is not necessarily feasible. The planner can then use capacity leveling to adjust the plan and formulate a feasible plan.
    2) PPDS Heuristic:-
    We run ppds heuristic to create procurement proposals for uncovered product requirements and to To carry out other planning tasks for products or orders.
    In PP/DS, a heuristic is a planning function that executes planning for selected objects (products, resources, operations, or line networks, depending on the planning focus). The heuristic does this using a particular heuristic-specific procedure.
    there are heuristics with which you can execute multilevel planning according to low-level codes for selected products, or with which you can schedule operations on selected resources in a specific sequence.

  • Difference between SNP heuristics,Optimizer and CTM

    Dear Friends,
    can any one explain me what are the basic difference in SNP planning methods
    1) SNP heuristics
    2)Optimzer
    3)CTM
    when should we use these  method in SNP , is all the methods are used in SNP impelemtation ?
    just give me some idea about it
    Thanks & Regards
    Raj

    Hi Rajkumar,
                      Please find the difference among three
    Comparison of the Planning Methods
    you use optimization-based planning or CTM planning if one of the following conditions applies to you:
    ·        Your business environment is subject to strict constraints (for example, you must take into account production capacities, transportation capacities, storage capacities, and/or handling capacities)
    ·        You have alternative production locations and sources of supply (locations, production process models, and external procurement relationships)
    ·        You can decide between early production and late production
    ·        You share resources, meaning that multiple products are produced simultaneously on the one resource
    We recommend that you use heuristic-based planning or CTM planning if any of the following conditions apply:
    ·        You wish to plan on an infinite basis (meaning that you do not wish to consider capacities) for the medium to long-term horizon (heuristic).
    ·        You wish to take into account predefined quota arrangements; for sources of supply, for instance (heuristic or CTM).
    ·        You wish to plan or fulfill demands on the basis of priorities (CTM).
    Optimization-Based Planning :
    http://help.sap.com/saphelp_scm2007/helpdata/en/09/707b37db6bcd66e10000009b38f889/content.htm
    The SNP optimizer offers cost-based planning. This means that it searches through all feasible plans in an attempt to find the most cost-effective (in terms of total costs). Total costs refers to the following:
    ·        Production, procurement, storage, and transportation costs
    ·        Costs for increasing the production capacity, storage capacity, transportation capacity, and handling capacity
    ·        Costs for violating (falling below) the safety stock level
    ·        Costs for late delivery
    ·        Stockout costs
    Heuristic-Based Planning
    http://help.sap.com/saphelp_scm2007/helpdata/en/a1/b60b4b2fc211d3b6270000e82de178/content.htm
    The heuristic is used as part of a repair-based planning process consisting of the heuristic, capacity leveling, and deployment. The heuristic run processes each planning location sequentially and determines sourcing requirements. The heuristic processing groups all demands for a given product at a location into one demand for the bucket. The heuristic run determines valid sources of supply and corresponding quantity based on pre-defined percentages for each source of supply (quota arrangements), or procurement priorities for transportation lanes and production process models (PPMs) or production data structures (PDS). The demands are then passed through the supply chain to calculate a plan. However, this plan is not necessarily feasible. The planner can then use capacity leveling to adjust the plan and formulate a feasible plan.
    Capable-to-Match (CTM)
    http://help.sap.com/saphelp_scm2007/helpdata/en/c4/986c39b768ca2fe10000000a114084/frameset.htm
    With this function, you can execute a multi-level, finite planning of the demands in your supply chain. Unlike the Supply Network Planning (SNP) optimizer that executes cost-based planning, CTM planning uses a heuristic procedure. In other words, CTM does not optimize the costs. Instead, you can use priorities, for example, to influence the sequence of demands and the selection of the procurement alternatives. CTM planning does not consider the individual production and distribution levels one after the other, such as the classic MRP run, but considers them at the same time. This guarantees that CTM planning generates a plan that can be executed on schedule.
    Hope these details will resolve your queries
