SAP BO system temp required size

Hi all,
Based on the title. I would like to ask a few questions.
During migration will it take up alot of space in /temp?
If yes,what's the /temp size I should allocate in my new environment before migration? Given my current filestore size is about 900GB.
Do I need to allocate another 900GB of space for /temp?
Please forgive if I ask the questions wrongly. Thanks.

Hi Yue,
The error you get because tool is using default value for parameters TEMP and TMP which in your case is /temp.
Please refer below SAP note to change the location for TEMP and TMP variable.
You may choose a path which has enough space.
1964197 - Upgrade Management Tool hangs during 'Export' phase with 'An exception occurred that prevents the reading or writing of an object to or from storage'
Hope this helps.
Regards,
Deepak Kori

  • SAP BW system Memory requirement

    Hi,
    We have SAP BW system version Business Information Warehouse 3.0B. System has following configuration:
    ~
    CPU : 32
    Physical Memory: 67108864 KB
    Physical Memory Available: 30654448 KB
    Database using Memory: Apprx 20 GB

    We are planning to restore this system to a test server. Test server is having 4 CPU and 8 GB RAM.
    Can you please let me know to do a restore, how many CPU and Minumum RAM We require on test server? How to check from current configuration, how much SAP is using memory?
    Appreciate your help.
    Thanks a ton in advance.

    To do that use the system copy guides at

    The actual memory can be checked using ST02.

    Hi  Arun,
    Thanks for the propmt reply.
    We are just planning to do a Disaster Recovery Mock Run. We will be restoring production server database to test server and will be recovering a database and then will start SAP.
    But not sure, if 4 CPU and 8 GB will allow to start SAP. Can you help? Currently Instance profile memory parameters has been set for 64 GB memory. I need to adjust the profile parameter propationately for the less CPU and memory ? how to check and do that.
    Appreciate your help.

  • Setting required to create Business partner record in SAP GTS for the customer who transferred from the SAP ECC system

    Dear Experts,
    Can you please suggest me list of activities require to automatically  create Business partner record in SAP GTS for the customer who transferred from the SAP ECC system .
    i.e If I create the customer master record and transfer the same CMR to SAP GTS , what are the setting requires to maintain in SAP GTS sytem to automatically create the Business partner .
    Ram

    Hi Raghu,
    Below are the main settings required to enable you to transfer Customer Master Data to SAP GTS. Please note that their is a difference between, Customer Master Record and Customer Master Data in terms of data and for GTS, we transfer Customer Master Data. Hence, below are the settings required:-
    In SAP ECC system:-
    Activate the change pointers for Customer Master Data apart from enabling basic connection settings.
    Schedule a job to run at regular intervals to transfer all the customer master data for the available change pointers to the SAP GTS system
      2.  In SAP GTS system:-
    Maintain the Mapping for ECC Customers to SAP GTS Business Partners in the General settings area of the SPRO in SAP GTS system
    Ensure that the Number range is maintained for those GTS  Business Partners.
    Also, some time you may be required to maintain the organisational structure to ensure full working.
    I hope this will be helpful to you.
    Regards,
    Aman

  • For Connect MS-Access to SAP - XI System , what Driver is required?

  • SAP BI System Copy with only Config changes, Not Data

    Hi BASIS,
    I have a requirement from a client to build a system landscape stratagy for their SAP BI system.
    We have DEV - QA - PRD systems for SAP BI (7.0 SP 16)
    Both DEV and QA are completely out of sync with PRD. We are doing development tasks directly on PRD. Now we have decided to re-sync the DEV & QA systems with PRD.
    'System copy with Data' will be easier to implement. But our PRD DB size is nearly 3TB. The client is not ready to pay for the extra/temp. disk space for DEV and QA sync. ( We are on DB2).
    Now, we have only one option left. Capture all Config changes from PRD and transport them back to DEV & QA. This is a tedious task and cause many inconsistencies.
    Would anyone have any other ideas to bring the systems in sync with less time involved and less resources.
    I am a SAP BI person. So dont know much about BASIS tasks. Please help me with any links of best practises or SAP notes.
    Cheers

    HI Reddy,
    We came to know from our basis team that we do not have the Java Stack installed in our BI 7.x system yet.
    As it is integrated with EP which has Java, our web reports are working.
    1) But my question is still do we ned to install the Java Stack in our BI system as i do not find any Export to PDF option in EP for the reports (eventhough AS Java supports this).
    2) Or can we use the existing configuration without Java STack integrated to EP for the new tools like Report Designer and Integrated Planning?
    Regards

  • Extracting Values of a Field from a Database Table in SAP ECC System

    Hi,
    I downloaded Extracting Values of a Field from a Database Table in SAP ECC System Using MII 12.0
    senario from sdn. I'm trying to do that senario in MII 12.05. But I have problem with section 6 in page 7 (you can supply senario from sdn)
    "6- Under the loop of Repeater, use action u2018Rowu2019 to append just the string part of the WA which will display only values for field u2018Batchu2019"
    I did not find WA elemen in Output element of Repeater_0
    How can I create WA element?
    Thanks.

    Cemil,
    Set up a SAP JCo Interface action block.  Use the RFC name RFC_READ_TABLE.
    In the link editor map the table to "MARA", set RowCount to something small (20 is good sample size) and create an xml transaction property named FIELDS and copy the following into it:
    <?xml version="1.0" encoding="UTF-8"?><FIELDS>
          <item>
            <FIELDNAME>MATNR</FIELDNAME>
            <OFFSET/>
            <LENGTH/>
            <TYPE/>
            <FIELDTEXT/>
          </item>
          <item>
            <FIELDNAME>MTART</FIELDNAME>
            <OFFSET/>
            <LENGTH/>
            <TYPE/>
            <FIELDTEXT/>
          </item>
          <item>
            <FIELDNAME>BSTME</FIELDNAME>
            <OFFSET/>
            <LENGTH/>
            <TYPE/>
            <FIELDTEXT/>
          </item>
          <item>
            <FIELDNAME>XCHPF</FIELDNAME>
            <OFFSET/>
            <LENGTH/>
            <TYPE/>
            <FIELDTEXT/>
          </item>
          <item>
            <FIELDNAME>DATAB</FIELDNAME>
            <OFFSET/>
            <LENGTH/>
            <TYPE/>
            <FIELDTEXT/>
          </item>
        </FIELDS>
    Then link the Transaction.FIELDS to SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/TABLES/FIELDS}.  You may run into problems with two other fields and optionally they can be removed (set link type to remove xml).  I usually remove them initially for testing.  The two fields are:
    SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/INPUT/NO_DATA}
    SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/INPUT/DELIMITER} (or you can set this to something like a semicolon,";" or tilda,"~".  I find it easier to caclulate position by length, but that is my own idiosyncrasy.)
    Once you get this one working, we can explore how to do filtering on the dataset.  Your output should be something like this:
    <?xml version="1.0" encoding="utf-8"?>
    <RFC_READ_TABLE>
      <INPUT>
        <DELIMITER />
        <NO_DATA />
        <QUERY_TABLE>MARA</QUERY_TABLE>

    Add a repeater sourced on:
    SAP_JCo_Interface_0.Response{/RFC_READ_TABLE/TABLES/DATA/item}
    Link your repeater output to a tracer with this:
    Repeater_0.Output{/item/WA}
    What you will see in each tracer message is a single line of data with all the fields contents concatenated together.  You can look up what each field in the string represents by the length of the field as returned in the Response segment of the RFC_READ_TABLE rfc.  Then you can parse out the data you are interested in.
    Give this a try and let me know how you succeeded.
    By the way, I could not find the scenario you referred to.  Can you post a link?

    3500 to 8500 is not a message count tht needs to be worried about
    but to be on the safer side what is the average size of a single message?
    if the size is not a significant one u can go ahead

  • Maximum Temp tablespace size you've seen

    DB version: 10.2.0.4
    Our DB caters a retail application . Total DB Size of 3TB. Its is a bit of mix of both OLTP and Batch processing environment.
    Our temp tablespace has 1 file and we had set the tempfile as AUTOEXTEND. Somehow its size has reached 25GB now !
    We don't actually need this. Do we?
    For a fairly busy DB of around 3TB size, what is the maximum temp tablespace size you've ever seen?
    What is the maximum temp tablespace size you've ever seen for Big DB like Telecom, Banking?

    The point about temp space is that your requirements are dynamic - the actively used area shrinks and grows.
    Comparing apples with oranges, tempfile sizes on system where I am currently here amount to 50 GB but to be honest that's mainly due to a not insignificant number of pretty poor queries, run concurrently, with multipass operations, etc.
    Kellyn Pedersen had an example of a process using 720GB here:
    http://dbakevlar.com/?p=43
    Whilst 25GB may not be earth shattering, a "large" temp area may perhaps be an indicator that you want to review some of your application code.
    (What is "large"? "unusual" compared to what is "normal" for your system may be a better metric)
    If you're using automatic pga memory management, then there's a limit to what each session can get, it may be that automatic work areas are not suitable for some of your code and some manual sizing is required to prevent operations spilling unnecessarily.
    Also, inaccurate CBO estimates on your queries can lead to inaccurately sized work areas that then spill into temp.
    There was a reminder of this in one of Randolf Geist's articles on hash aggregation:
    http://oracle-randolf.blogspot.com/2011/01/hash-aggregation.html

    Hi,
    With regards to your statemetn "SDN downloaded document says to Generate Webservice URL through ABAP"   <- can you tell me more please? references/links/attachment?
    As far as I am aware, that the type of web service required for integration it a 'normal' Netweaver Web app server web service.
    There are limitations about the complexity of the WSDL - see Notes:

  • Switch over between two SAP PI systems for downtime minimization

    Hello Colleagues,
    with our interfaces over our SAP PI 7.31 (ABAP/Java) system we assume we will run in a 7x24 h runtime scenario in the future.
    Regarding Business Continuity we have to think about solutions which help us to handle downtimes greater than 15 min. regarding Support Package upgrade, Kernel update, EHP, etc.
    The first idea is to implement a second equal SAP PI productive system in parallel to the existing one.
    On the sender side a switch over implementation like WebDispatcher, Load Balancer, etc.
    For maintenance all Interface traffic can run over PI Nr. 1 and PI Nr. 2 can be updated.
    Afterward all interfaces will switched to PI Nr. 2 and PI Nr. 1 can go in maintenance.
    Could be this as suitable solution for SAP PI Business Continuity or do you know better solutions?
    Many thanks in advance!
    Regards,
    Jochen

    Hello Bernhard, Hello Holger,
    many thanks for reply and providing these valuable information's.
    The nZDM Concept is already known to me but it doesn’t answer all our questions.
    Please let me explain a little more in detail.
    Not currently but in the near future we assume some new interface over our SAP PI System will come with the requirement max. downtime lower thank 10 to 15 min. only allowed.
    To be prepared regarding this possible scenario, we start thinking about possible different solutions.
    First step was the nZDM Concept, of course. But it didn’t meet all our requirements regarding interface downtime.
    Some points are:
    possible min. downtime is 30 min. and thus is over our requirements for interfaces
    only for Update (and planed for Upgrade) the SAP PI application
    all operating system and database related maintenance tasks are not covered by nZDM
    all Hardware (Server, Storage, etc.) as well not covered by nZDM
    Among others, because of these facts we start thinking about a second equal SAP PI system beside to existing productive one.
    Than line 1 will take over the whole interface traffic and in the meantime the line 2 can go in maintenance. After finalizing the maintenance for SAP PI Nr. 2 we can switch the interface traffic to SAP PI Nr. 2 to get SAP PI Nr. 1 free for maintenance.
    Regarding the topic “PI Federation” I found here in these documentation's several hints regarding this scenario (two SAP PI systems in an switch over scenario).
    PI Federation – An Overview
    among others  Page: 27
    Business Continuity: Central PI integration Server with redundant Integration Server to be used in controlled switch over scenarios when upgrading or patching.
    or
    How to Fast-Switch Integration Scenarios between SAP PI Runtimes Part II: Web Dispatcher
    But I didn’t found any further detail documentation's regarding this approach.
    The solution should fit as well to our existing hardware infrastructure.
    For production we use an IBM (AIX) failover-cluster switch between our both data center.
    Regarding our hardware infrastructure prerequisites and downtime requirements, which solution(s) do you recommend? Is PI Federation still an option?
    Many thanks in advance!

  • Error while creating source system entry in SAP BW system

    Hi,
    I am creating source system entry in SAP BW system for ECC system.In T-Code RSA1 i entered all the details of source system and BW system like RFC destination of source system and RFC user passowrd.
    After clicking on enter system is promting me to enter into the souce system using administrator user.but i don't have admin user with SAP_ALL and SAP_NEW profiles because in my organisation they don't assign these profiles to any user.
    So can you please update me what are the authorization required for dialog user in source system.
    Regards,
    Gaurav

    I would recommend to create a USER ID as COMMUNICATION type and assign SAP_ALL for it... this way, it can never be misused..
    This will ensure that the user ID will have correct authorization in the source system and will not face any authorization related errors later on

    Item type retrieval and registration requires a connection to the systems and may take a couple of minutes
    For each system, they are generated as the configuration named 'uwl.webflow.<system_alias>' or 'uwl.alert.<system_alias>'.
    After configuration changes in the backend system, you must re-register the system.

    Hi,
    you can check few things prior proceeding:
    Does your connector test after adding your backend system in portal works fine?
    Did you define a system alias?
    Make sure your SSO is working,
    Also check your Jco detination webdynpro tab.

  • Hi, what's the impact of creating sites through configuration in Sap retail System?

    Hi Experts,
    Business requirement is to have a production plant created through config in retail system and then ship the finished product to DC using STO's and Dc will be created as master data in retail system. please share your experience on business impact on this integartion of production plant and site in Retail?
    Thanks in Advance !

    Hi Govind,
    In SAP Retail system, the options for creating plant from configuration is disabled. Means in SPRO screen, the execute button is not there for these options. So you will not be able to create plant through configuration in SAP Retail system where the retail switch is activated.
    All the Retail related features will not support that plants.
    To the best of my knowledge, Site created in Retail system using WB01 transactions can be used for production cycle to implement manufacturing scenario. Using article to article stock transfer you can transfer the stock of Finished Goods articles to trading articles and so on.
    Various processes are available for this.
    Let me know if you need any more information.
    Regards,
    Amit

  • Need suggestion on importing BC SET : UKM_DCD_CUST in SAP ERP system

    Dear Gurus,
    Client wants me to import BC SET : UKM_DCD_CUST into SAP ERP system. I have found BC SET : UKM_DCD_CUST in T code SCPR20.
    I have read most of the SCN discussion and got two way to import BC SET into ERP system as given below. But I need the appropriate way to do this. Can any one help me in this?
    1. SCPR20 -> Activate BC set -> create customizing request to import into another system as per link :Business Configuration Sets (BC Sets) and their use - Basis Corner - SCN Wiki
    2. Create TR in SE01 in 000 and import into required client  as per below proc:
    Usual procedure
    1) BC SETS will be attached to SAP note usually. Download it and unzip it , you will get a *.bcs file
    2) Call transaction SCPR20  BC set --> Upload In the dialog box that then appears, specify the files that you unpacked
    Import the set BC into a package that you have defined. activate it with the "Expert mode"
    3) You will also get a *.txt file with prog id , obj etc entries , then you have to go to SE09 and create a transport request in the source client of your Solution Manager system (client 000). Open the *.txt and copy the entries it contains into the transport request. Use transaction SCC1 to import the data in your Solution Manager client(s)
    Thanks,
    Anand Aseri

    2). Client copies bring the Customization data but not WorkBench . So you might have to do transport of copies from Old Dev to >New Dev.
    So you are saying that the system copy from Production will not bring Workbench data and I need to bring Workbench data by transports?
    *system copy from Production will bring Workbench data also, but when you do client copy from development system again on top of client which already has production customization, data and workbench requests, Production customization and data will be overwritten from development customization and data (it depends on the profile you choose for the client copy) *
    However  Development Workbench requests are more and also has ongoing development work which might not be available in production client and those (Ongoing development workbench requests) you need to import in new system as transport of copies after the client copy
    3). If you do system copy from Production and do client copy from dev...obviously Prod customization will be overwritten with Dev rite ?
    That's what I expect to happen,
    Ok, however, You might need to get Development Work too from the old dev system and don't forget about setting up of partner profiles in WE20.
    It's just a thought ,  Do you have testing client in Dev, if not,You can leave the production client in development system and use it as testing client.
    Create new client which is client copy of Old Dev and import WorkBench requests *
    Thanks,
    Arjun
