APO and LiveCache Optimization

Hi All,
Can anyone share some points to optimize APO and liveCache, like best practices, system configurations to improve the performance of our system?
We would appreciate your response and inputs.
Regards,
Philip Lledo

Hi Philip,
There are definitely few things that you can check in your system -
Make sure for every long job execution step you have enough buffer left in your storage space. Monitor storage quality and determine how often it should be executed. Also avoid any locks for long time in SM12.
You may consider using external parallel processing profile (divide one big job into several jobs) for the job, which takes long run time. Find optimal package size by increasing value like 150, 200…you can do some experiment to find a better combination for your parallel processing profile. Like, Increase the number of parallel processing. i.e. 15, 20…and try to find optimal block size by reducing value like 250, 125, 60.. in your QA system. Also consider applying Note 1359613 - SNP Optimizer: Parallel processing is slow.
Check the current spool list in your job logs. See if you really need the entire spool or you can reduce the volume of the spool file or stop creating spool file as applicable.
Make sure your Load balancing for RFC is set properly in your APO System, analyze the current situation by taking help from your Basis team.
Check the RFC recourse utilization in every server path/instance. There should not be any scenario, where one instance is used almost in full, while there are many free work processes on other instances. The reason for this is that there is no load balancing defined in your APO system. There is a SAP note 593058 for more details to set the load balancing within the server group.
You can do some experiment in your optimizer profile (if you are using SNP/Deployment optimizer for planning) in QA system- In your optimizer profile, try to reduce the value of ‘Maximum Runtime’ and checked. You should consider the quality of result of the optimizer run here. Then decide if this is an option at all.
Also you may consider to reduce the horizon for your optimizer run, if applicable. May be you don’t need to run the optimizer for full planning horizon, if you are not really publishing for full horizon. Also consider to reduce your no of buckets in the planning horizon if possible, Like you don’t need to have all the daily bucket in the horizon, may be first month in daily bucket. You can determine planning horizon in the variant.
Remove any inconsistencies in LC every day after executing the report and make sure to resolve all the inconsistencies before executing major planning job. Also Monitor post processing record regularly and process them accordingly.
By checking/doing all the above, you should get some pointers.
Thanks,
Satyajit

    Hi Farooqui
    Since this Forum handling more application related topic, it is better to post your question in different Forum "MaxDB/liveCache ".
    Above MaxDB/liveCache is handling more basis and liveCache related topic.
    As a general information, SAP provides following documens that describe task and check point related to SCM system and liveCache. So I recommend you to check following 3 documents.

  • APO Shared LiveCache

    Hi
    Can anyone from the forum help me to understand the below points.
    1.if a test instance of LiveCache can be shared with multiple APO systems and what would be involved to set it up?
    2.would it make sense to share APO systems (i.e., connect a single APO and LiveCache to multiple ERP systems).
    Appreicate for quick response.
    Regards

    Hi Devi,
    Do you have a specific business case for point no 2? I have newer seen such a implementation. It should be possible though by maintaining appropriate distribution definitions.

  • SNP planned order availability date difference between APO and ECC

    Hi,
    I have observed that SNP Planned order availability date is not matching between APO and ECC. Details are as follows.
    I ran SNP Optimizer with bucket offset of 0.5. After publishing the optimizer created planned orders to ECC, only start date is matching.
    Example:
    I am using PDS as a source of supply.
    Fixed production activity in SNP PDS is 1 day.
    GR processing time: 3 day
    After running optimizer planned order is created with dates explained below.
    Start date/time: 09.05.2011 00:00:00
    End date/time: 12.05.2011 23:59:59
    Availability date: 16.05.2011 00:00:00
    Because of bucket offset defined as 0.5 optimizer planned order availability is start of next monday.
    After publishing this planned order to ECC dates on the planned order is as follows.
    Start date: 09.05.2011
    End date: 09.05.2011
    Availability date: 12.05.2011
    I have not maintained any scheduling margin key in ECC. Also if I dont define the GR processing time, planned dates between APO and ECC always match. Can anyone explain the impact of GR time on the availability date.
    Regards,
    Venkat

    Hi Venkadesh,
    What's "state stamp"? Do you mean different time zone?
    note : 645597  mentioned by Nandha is very helpful:
    In standard, CCR will use duedate - "the available date of the output product".
    Nandha's words "In SAP APO, if the receipt date of the primary product deviates from the
    end date of the last activity of the order, the receipt date
    always identifies this as inconsistent. You cannot rectify
    inconsistencies of this type by using CCR."
    I guess in your PDS or PPM, the output product is not assigned to the End of the last activity. Someone changed it?
    Please CIF the PDS or PPM again.
    If you really want to apply a note, please use note 815509 as you're using planned order,
    and system will use order end  date in CCR instead.
    GR time is always considered. BR/Tiemin

  • Differences between APO and R3 sysytem.

    Hi everybody,
                        Can anyone list out the differences between the APO system and the R3 system.A detailed explanation will be helpful.

    Hi,
    APO
    APO is the supply chain tool from SAP.
    BW is the data layer for APO.
    SAP APO is for Demand Planning and is a component of mySAP SCM. It enables dynamic supply chain management and which in turn includes applications for detailed planning, optimization and scheduling, allowing the supply chain to be accurately and globally monitored even beyond enterprise boundaries.
    SAP BI is a reporting tool in SAP. It provides a complete view of the company. The solution is part of SAP NetWeaver and provides the tools needed to make the right decisions, optimize processes, and measure strategic success: data from all enterprise sources are merged effectively and can be comprehensively analyzed, business-critical factors can be monitored using external and internal benchmarks, the most important KPIs can be passed on to all the relevant forces in a company in real time, strategies can be rapidly adapted to changed market conditions, and the results of analyses can be graphically represented in a wide variety of formats, such as grids, graphs, and maps
    Check this:
    What is APO and how it is related to BW
    SAP Advanced Planner and Optimizer is a component of the mySAP Supply Chain Management solution that you use for planning and optimizing supply chain processes at a strategic, tactical, and operational planning level.
    With APO - Simultaneous Material & Capacity Planning is possible, as against R/3 PP
    APO Planning is capable of taking all the constraints into consideration with Planning for Capacities/Scheduling
    APO Resource (workcenter in R/3) does a Capacity availability check before scheduling an activity, if capacity is not available, it finds the immediate next available slot & schedules the activity there. This is not possible with R/3

  • Update from ATP timeseries indicator different values in APO DB & Livecache

    Hello experts,
    Our Basis team has ran the Livecache and DB consistency check (OM17) transaction and all the inconsistencies has been removed,but we are encounturing an error "The update from ATP time series indicator has different values in APO DB and Livecache " in 000 version. I have checked the version managemet for 000 and under ATP tab the option Update from ATP time series is unchecked. Can you please let me know the reason for this error and what else i.e. the configuration settings i have to check to wipe out this error.
    Quick help is appreciated.
    Thanks.
    Dhanunjay.

    Hello Kaushik,
    Thanks for your reply.
    The indicator update update from ATP time series is only set during the creation of active version for product availability check time series update, but we are not using any ATP time series.
    How ever it's unchecked for active version 000, but when i checked for the entries in the table /SAPAPO/APO01 there the ATP time series activation indicator is set. Iam confused  about the differences, i guess this might be causing the error,if so i have to alter the table or delete the version and recreate. Can you please guide me which would be the better option.
    Thanks.

  • Difference between APO and SCM

    Hello All,
        I am new to SAP...
        Can somebody tell me the difference between SAP APO and SAP SCM.....
    Regards,
    Mary

    Hi,
    SAP Advanced Planning and Optimization (APO) is the planning component of mySAP SCM, the supply chain management solution provided by SAP.
    SAP APO is used to make strategic, tactical and operational decisions and supports you in performing the following planning activities:
    Demand Planning (DP)
    Supply Network Planning (SNP)
    Production Planning (PP)
    Detailed Scheduling (DS)
    Deployment
    Transport Load Builder (TLB)
    Transport Planning and Vehicle Scheduling (TP/VS)
    Global Available-to-Promise (gATP)
    SAP's endeavor into the advanced planning solution market was with the name SAP APO. There are other APS solutions in the market from Oracle, Manugistics, i2 and a whole host of other companies providing specialized planning solutions
    Over the years SAP has brought the SAP APO solution under a wider umbrella called SAP SCM. Since version 4.0 of APO it has been called SAP SCM. So in the release strategy of SAP you will find SAP APO 3.1 followed by SAP SCM 4.0
    SAP SCM is a more complete solution that covers planning, networking, coordinating and execution. In addition to SAP APO, which is still the core of SAP SCM, there are other applications such as SNC (Supplier Network Collaboration - erstwhile ICH), SCEM (Event Management), EWM (Extended Warehouse Management) and SPP (Service Parts Planning)

  • GATP in APO and Free Goods Pricing Records in R/3

    We have set up Free Goods in SAP R/3. These free goods are granted based upon a series of access sequences in pricing.
    We also have our Order Entry system using GATP on our APO box. In that APO instance, we have set up a large number of product substitutions to occur at order time.
    When an item is ordered that is NOT subbed to different item by APO and that item has Free Goods associated with it, the Free Goods are granted by R/3 and placed onto the sales order.
    When an item is ordered that IS subbed to different item by APO and that item has Free Goods associated with it, the Free Goods are NOT granted by R/3.
    Why are the Free Goods being ignored after the substitution? We have Free Goods records in pricing for BOTH items, and neither one is granting the Free Goods.
    Is this a bug, a feature, or an oversight ?
    Any help in this area will be GREATLY appreciated!!!

    Hi John,
    GATP in APO does not supports Free Goods.

  • Problem with call-offs between APO and R/3 system

    Hi, gurus.
    We have following problem:
    APO system receives DELINS idocs. They are processed correctly (status 53). But sometimes the call-offs in R/3 system are not updated. I do not know much about the underlaying process but how can I check where the problem is?
    I suppose it can be caused by blocking of particular material or order or whatever in R/3 system when the call-off is being processed. But then the system should give some warning. I need to know where it could be found.
    The only workaround at the moment we do is to create copies of DELINS in APO system and let them be processed.by APO and consequently by R/3 system.
    Thank you.
    Stano Letko

    Hi Stano,
    When ever IDOC fail you can trigger a workflow to the respective person through Partner profile and message type setting .(we20) as Post processing permitted agent .
    Get in touch with techincal person who have idea of  IDOC configuration.
    Message type : DELINS
    Partner number : XXX

  • Dangerous APO and BI Transaction codes

    Hi experts,
    I have question Dangerous APO and  Transaction codes
    Background :
    We are in the process of implementing SOX controls for the new APO and BI Systems
    Questions :
    What are the Dangerous APO Transaction codes which should not be assigned to any one in Production system
    What are the Dangerous BI Transaction codes which should not be assigned to any one in Production system
    Additional Notes
    System which we are having
    APO
    Version  : SCM 5.0
    BI
    Version : BI 7.0

    Praveen,
    I am a puzzled that you would ask such a question.
    Authorizations ALWAYS derive from requirements.  In this case, Sarbanes-Oxley speaks of control mechanisms.  Your SOX auditors should tell you what they consider to be critical, and they should advise the client company as to which transactions should be controlled, and how best to control them.
    There is no transaction that should be disallowed to everyone.  That would eventually make the system unusable.  The question is, "how many people should have these critical transactions, and how should the execution of these transactions be monitored and controlled".
    Generally, the APO portion of SCM should require less SOX controls than ERP, since APO is mostly a planning system, and not an execution system (there are some exceptions here though).  Likewise, the BI portion of SCM usually contains no financial reports, and therefore should have relaxed controls over, say, the main BI instance used by your company.  
    Don't make the mistake of strangling yourself to satisfy your perception of what you think an auditor may require.  Make them tell you the minimum requirements for compliance.  Anything beyond minimum compliance with SOX is costly.  This question is then a matter of your company's policies.  I usually vote for 'no additional restrictions' (but my poor vote doesn't usually count for much).

  • Data from R/3 to APO and vice versa

    Hi,
       Does anyone know what data is usually sent from R/3 to APO and from APO to R/3?
    Thanks

    Hi Disha,
        could you please let me know what is PPM and also what data is transferred back to R/3?

  • PPDS production order dates mismatch between APO and R3

    Hi Friends,
    We are facing one problem regarding production order date mish match between R3 and APO systems specific to a product.
    The product is planned in PPDS and the order automatically transfer to R3 through online CIF.
    PPM has got two operations 0010 and 0020 and activity relationships are like this:
    P(0010) - P(0020) Start - Start relation ship
    S(0010) - P(0010) End - Start relationship.
    In PPDS dates are shown as :
    on operation 0010 the start/end  dates are shown as  08.15.09 to 08.22.09
    on operation 0020 the start/end  dates are shown as 08.15.09 to 08.22.09
    Overall order start date is  08.15.09
    Overall order finish date is 08.22.09
    and in R3 dates are shown as:
    on operation 0010 the start/end  date are shown as  08.15.09 to 08.22.09
    on operation 0020 the start/end dates are shown as 08.22.09 to 08.29.09
    Overall order start date is  08.15.09
    Overall order finish date is 08.29.09
    The order is off one week (APO vs R3) with start and finish dates.  
    if we change DS Board settings to ignore internal relationships manually then the dates are matching exactly in APO and R3.
    We want the production order dates to be matched without manual intervention.
    Could some one please provide some hints on what is happening here and how to correct it.
    Thanks.
    Krish

    Hi Friends,
    Thanks a lot for your valuable replies in this regard.
    Actually this problem is in production environment and it took some time to test the problem with the master data modifications
    you suggested.
    As DB and Siddhrath mentioned, the problem was with routing definition. There is no parallel sequence maintained in the routing but there is start-start relation maintained in APO PPM.
    We corrected the routing definition and checked the order dates. Now the dates  are matching in R3 and APO.
    I am awarding DB and Siddharth each five points in this regard.
    Once again thank you all for your time and valuable replies.

  • APO and BW on separate systems

    Hi guys,
    we are currently setting up a new landscape our company.
    We'll have one APO (newest version, 7.0) with life-cache and one BW (7.0). I am just wondering, why we create two systems and not just one, because APO is based on the BW technology. I had already a look in the notes but didn't find any proposals.
    Has someone an opinion or a link for me?
    Thx in advance
    Harald.

    Hi Harald,
    you are right, APO has a built-in BW system. basically, it is possible to do reporting (APO related) on the same box. However, there are serval reasons that some customers would prefer to have APO and reporting platform separated:
    1. For performance reason (APO vs BW)
    2. Internal BW system is not recommended for other reporting (R/3, or legacy reporting) also for performance reason, because to load and report additional data means additional overhead for the system.
    3. in the past (prior to SCM 5.0), APO has had only current BW release - 1 ->> with limited reporting capability.
    Hope it helps.

  • APO and BW

    Hi Group
    We have BW 2.1 installed at the moment just for reporting purposes. We are in the process of migrating the reporting to another software. In 3 months we will fully complete the migration to the new reporting software. Thus we will not be using BW anymore.
    At the same time, we are going to implement APO. I understand APO comes with BW also.
    1) My question is, can we expire the existing BW and not use the BW that comes with APO?
    2) I also hearing that APO needs BW engine? Is this true?
    Our intention is to expire the BW completely and use the new reporting software. Also want to use APO for VMI.
    Kindly advice.
    Thanks
    Yuva

    Hi,
           You get BW along with SAP SCM-APO system and cannot be separated. The SAP BW system is fully integrated in APO and can be installed on the same server. The version of BW depends on version of SCM. It can be used to store data but cannot be so performance effective for reporting. You may use the external BW system to report but not needed. You can use BW in APO system to use for all purposes such as storing history from other systems, get the data from APO and store etc. If you dont want an independent SAP BW system, you can still workout. You can store the required data in APO-BW and using reporting tools such as cognos and report on them. SAP BW has a technology named OPEN HUB that lets it send the data from cubes to other systems.
    Finally:
    1) My question is, can we expire the existing BW and not use the BW that comes with APO?
    A: Yes you can expire your independent BW system but cannot live without APO_BW as BW in APO is not separately. You have to use BW atleast the one that comes with APO.
    2) I also hearing that APO needs BW engine? Is this true?
    A: Not completely true. As I said, if you don't want to report using BW, leave the independent BW system and use an external reporting tool to report in BW in APO.
                 In V5.0, there is more flexibility. You can load data to planning area from flat file directly bypassing BW. But if you want to avoid BW all together, you life could be miserable!
    For more information see service.sap.com/scm.
    Let me know if you have any questions.
