SNP Optimizer - unfullfil demand

Hi
I run snp optimizer for 1 product A, it work out fine . subsequently i run the same optimizer for the a range of products ..  . it overwrite the result and cause unfulfill demand for product A.
Any particular area i need to look out ? i cannot just keep running optimizer for that single product to fulfill the demand .
remark
all the product is imported finish goods

Hi,
the possible check you need to carry out to get the reason of the  unfulfilled demand.
1. Check the resource consumption used by that particular product. Possibly the resource might have been consumed by some other products.
2, Check the Planned orders generated for
2. Check the cost in the PPM , Tlane, and Product master. Compare with the products which are using the Location resources used by A.
3. CHeck the Penalty costs maintianed to check why the priorities are given to  other products.
for the all the above you see in /SAPAPO/SNPOPLOG
Hope this helps.

  • SNP Optimizer dropping the demand

    Hi,
    While planning using SNP Optimizer against a given demand in a constraint scenario, the optimizer is dropping significant demand.
    Capacity of the production factory is not constraint. But somehow a lot of demand is not propagated to the factory. In fact, out of the 3 factories where one product can be produced, one factory did not get any plan at all !!!
    Can you please help me understand the other possible reasons why this can happen? The master data - Lanes and production master data at the factory is maintained correctly.
    Regards,
    Ankur

    For a demand to be considered in the optimizer Run following are the checks to be done:
    1. Lane should be defined from a location where the demand is to a valid source. (lane can be at location level for all product or lane can be product specific)
    2. Cost definitions: If the production + transportation cost for the product at source is greater than the Demand loss cost at dest loc there wil be a demand loss. Please update the Demand Loss cost in /SAPAPO/MAT1:- SNP1 tab. Total demand loss cost after planning is avaialble in IT_NONDELV table in Optimizer Log
    3. Capacity avaialble for planning. resources to be properly defined and capacity availability to be checked (IT_RESOURCE) will give the details wether the reource is avaialble
    4. If a PPM is used with output componenet demand uinmet we need to check whether the input product is produced (capacity to be checked for input Product production to happen)
    these are few basic checks for Demand Unmet

  • SNP Optimizer demand priority

    Hi ,
      In SNP Optimizer What is the "Corrected Demand Fcst " corresponds to which keyfigure in SNP?   My understanding is "Customer Demand" => Sales Orders (Category BM),  Demand Forecast => Forecast (ie Category FA). I can't find any mapping for Corrected Demand Fcst.
    Shibu

    Hi,
    You can create a custom category group and attach all the categories of forecast for the customer you want to, maintain this category group against the Forecast (correlated)  key figure in the Planning Area.
    Also include this key figure in the planning book.
    Thanks,

  • SNP Optimizer run ends with error: Error when determining Customizing data

    Hi All
    Can you help please what settings are missing: SNP optimizer run canceled with error "Error when determining Customizing data".
    Thanks
    Best Regards
    Andrey

    On integration tab of SNP optimizer profile,
    maintain 'regard as customer demand' for both dependent demands and distribution demands for fixed orders.
    By default it is 'regard as hard constraint' which should be changed.

  • How to determine runtime of SNP optimizer

    Hi Experts,
    I am new to SNP optimizer, i would like to know the factors that determine the runtime of SNP optimizer,
    for example if i have 100 product-loc combination, what should be my runtime?
    Thanks in Advance
    Raja kiran R

    Hello Raja
    Following details are based on my recent experience/learning's while working Optimizer runtime(it was a nightmare)
    SNP Optimizer varies regardless of number of location products or demands.
    SNP Optimizer runtime is split into following 3 main steps -
    Runtime 1. Reading input data
    Runtime 2. Solution Calculation and
    Runtime 3. Order Creation.
    Runtime 2 is usually varies depends on degree of problem complexity and number of iteration optimizer has to go through before finding cost effective/optimal solution.
    Analyzing the optimizer logs/trace file and collect various statistics/facts for couple of weeks can give you some idea on optimizer runtimes.  Use below Tcodes - /SAPAPO/OPT11 and /SAPAPO/SNPOPLOG for collection such statistics on following criteria's -
    Please keep a watch on inputs like - Number of products, locations, location products, transportation lanes and demands.
    and Output like Total Fulfilled Demands, Total Un-Filled Demands and Total number of stock transfers.
    and Result Indicators like how many ProdDeco iteration,  Solution Quality/ Cost iterations and what is the Service Level achieved.
    Besides, you can control the Optimizer runtime by setting up the Maximum Runtime(in Minutes) in Optimizer profile. Also use Parallel profile process for improving the performance of the optimizer run.
    Also ask you basis team to watch system performance when it is reading data from livecache, solving the problem or creating orders in livecache, if there are any memory issue etc.
    Hope this will help.
    Thank you

  • Considering Forecast in the past for SNP optimizer

    Does SNP optimizer considers the forecast in the past as a requirement?
    I tried with standard book and dataview but SNP optimizer did not consider past forecast. I checked optimizer log, forecast was not there also.
    Am I missing something? Or is it default behaviour?
    Thanks.

    Hi
    Yes that is the default behaviour, essentially the Optimiser has assumed that anything in the past has already occurred and will only start to plan demand from the first bucket onwards.

  • SNP Optimizer and dummy procurement

    Hi,
       Is there anyway SNP optimizer don't create dummy purchase orders at the distribution center?  We have high penalty cost for non delivery.  If there is no supply available/ (or some reason master data is missing), Optimizer is creating Purchase requisition without any source of Supply. We want to avoid this Purchase requisition.
    Thanks everyone for sharing your expertise.
    Shibu

    Hi,
    Optimiser will not create Pur Req with source as blank if the supply is not avaialble at the source, instead it will incur demand loss cost.
    Opt will create PR with source blank only if you have define Procurement type as F and no source has been defined, you can either define a source or change the procurement type to E.
    Also their is a note in case of optimiser which prevents creation of PR with source as blank, but I am not able to access the SAP notes and so cant provide you with the note number, you can just check out.
    Thanks,

  • Penalty Cost Groups in SNP Optimization

    Hello APO experts!!
    I would like to know if any of you have more information about the of penalty cost group in SNP Optimization.
    I have been researching on the help.sap.com web site but I need more details.
    Can anybody help me?
    Best Regards
    Angela

    Hi Angela,
    1)  You can use penalty cost group for optimization-based planning in Supply Network Planning (SNP) to define that customer demand is prioritized.
    2) You can use the Business Add-In (BAdI) /SAPAPO/SDP_RELDATA to assign penalty cost groups to forecasts and sales orders
    3)  You then release the forecasts with descriptive characteristics, such as customer, to SNP or transfer sales orders from SAP ERP to SAP SCM via the Core Interface (CIF).
    4) In SNP 1 tab page for product master data, you can assign penalty costs for non-delivery and delays to the penalty cost groups. In this way, penalty costs become customer-dependent.
    5) You can use the penalty cost group to define that the system first covers the demand from penalty cost groups with a higher priority, and only then covers penalty cost groups with a lower priority.
    6) Penalty cost groups are controlled by penalty cost group profiles
    7) You define the profiles from the SAP Easy Access menu, by choosing Advanced Planning and Optimization -> Supply Network Planning -> Environment -> Current Settings -> Profiles -> Define SNP Penalty Cost Group Profiles and then assign them to individual optimization runs in interactive planning or when executing the SNP optimizer in the background.

  • Product variant constraint in SNP optimizer run

    Dear All,
    I have a business scenario where I require a constraint on the number of FG variants produced per day. A number of FG SKUs come under a particular variant. On any day the factory is able to produce only a fixed number of variants (say 5). I am looking for a way to map this constraint in optimizer run.
    Will appreciate your thoughts to solve this problem.

  • SNP Optimizer Issue

    Hi Experts,
    We are working on SNP Optimization scenario with Transportation, Procurement, Strorage and penalty Cost. Our business process trading industry (we procure and sell).
    We maintained Optmizaion profile with linear and Primal simplex Algorithm. We took a sample scenario where our product has four suppliers with diffrent transportation costs maintained in transportation lanes.
    In SDP94, Optimizer behaving diffrently.
    Case 1: When we run directly at destination location (product + Destination) level optimization running smoothly with out picking any transportation lanes, costs. Subsequently no purchase requistions are created.
    Case 2: When we select all locations (Product + Source and Destination) and run optimization the following errors are coming which we are not able to identify the origin.
    Error 1: Cost function 051MhWG07j6MwgLZXQcXSm not found
    Error 2: Conversion from STD to EA for product WDE-MATL1A not maintained
    Error 3: Error occurred when reading data
    We checked CCR no errors are identified. Also there is no UOM called STD. We couldn't understand why Optimizer is proposing STD to EA conversion error.
    Can you please throw some light.
    Thanks in advance

    Hi Ugameswara Rao
    When you run optimizer,you need to run as a whole including all teh Network...So,the first observation is standard
    Regarding teh second issue,It is a Master data inconsistency,So,please identify the 'concerned location product' and maintain the cost accordingly(Check teh log to find the concerned location product)
    Regarding error "Error occurred when reading data",please raise a seperate thread,as the raesons for this are multiple...but try this first run //om17,model consistency check and correct the data model set...but,the reason for this could also be a softwre error....hence,if the above don't help,please rasise a seperate thread with all details like: STEP in which thi serror occur,and also teh message log details
    Thanks and Regards

  • SNP Optimizer  With Runtime Errors

    I am Trying to run SNP Optimizer.
    The actions performed on SNP Interacive planing book is Selected the Product Locations in Selection window and When trying to load data or click optimizer it is giving a  runtime error.
    The Error Says: A table is refered to in a SAP open SQL statement that either does not exit or is unknown to the ABAP dictonary.
    Table involved is /SAPAPO/STOCKANC.
    Please , can anyone help me understand. What the error is and how to go about it?
    That would be a great help.
    Thanks
    GAyatri

    Hi Gayatri,
    Very first check is already mentioned in the error message.
    Did you check that the table "/SAPAPO/STOCKANC" exists in your system? When you would dispplay the table in SE11, you should see against the table name that it should show up as "active".
    Click on "check" and then "activate" button if the table is not active. This would make it active.
    Alternatively take help from your ABAP colleagues.
    (Table should have a description "Key and Descriptive Data for Stock". You should also try to find out if recently some OSS note was applied which is causing this kind of issue)
    Thanks - Pawan

  • Deletion Time Period at SNP Optimization

    Hi!
    I'm facing some problems at my SNP Optimization due a wrong Deletion Time Period.
    Where could I maintain the "Deletion Time Period" (DEL_TRANS and DEL_PROD) for SNP?
    Thanks a lot!
    Victor Leao

    Hi Pawan,
    Thanks for your reply.
    In fact, it is not a program error. The situation is the following:
    For example:
    I have some SNP documents (stock transfer) at 23.12.2011. They were generated at the last optimization.
    Now, a new optimization is run and some documents at 23.12.2011 were not deleted.
    Checking the "Deletion Time Period" (DEL_TRANS) at SNP Optimization Log, I see that for those products the "Start" is 06.02.2012 and the "Finish" is 06.05.2012. So, documents before 06.02.2012 are not considered for deletion.
    The products wich documents were deleted have "Start" at 01.01.1970 and "Finish" at 06.05.2012.
    I would like to understand how can I maintain those dates for DEL_TRANS.
    Thanks in advance,

  • SNP Optimizer with PDS

    Hi Guys,
    Is it possible to use SNP PDS with alternate mode for SNP optimizer in SCM 7.0 , If it is not possible then how to create many SNP PDS if there are alternate resources assigned for the product.
    Thanks and regards
    Thamizh

    Hi Thamizh
    You can not create SNP PDS for alternate mode.
    You need to create different production version for alternate Mode. Only that way you can send SNP PDS.
