Pre-fill the OLAP cache for a query on Data change event  of infoprovider

Hi Gurus,
I have to pre-fill the OLAP cache for a query,which has bad performance.
I read a doc 'Periodic Jobs and Tasks in SAP BW'
which suggested sum steps to do this
i hav created the setting for Bex broadcasting for scheduling job Execution with data change in info provider
thereafter doc says  "an event has to be raised in the process chain which loads the data to this InfoProvider.When the process chain executes the process u201CTrigger Event Data Change (for Broadcaster)u201D, an event is raised to inform the Broadcaster that the query can be filled in the OLAP cache."
how can this b done please provide with sum proper steps
Answers are always appreciated.
Thanks.

Hi
U need to create a process chain or use the existing process chain which you are using to load your current solution, just add event change process type in the process chian  and inside it add the info provider which are going to be affected.
Once you are done with this go to the broadcaster  and  create new setting for that query...you will see the option for event data chainge in infoprovider just choose that  and create the settings.
hope it helps

  • How to empty out Olap Cache for a query?

    Hi experts,
    I think the olap cache for a query should be resetted to zero after a data load (right?), if i have understood well how it works. Where can i check the olap cache for the query?  I'd like to ckeck the change of the Olap Cache for a specific query.
    I checkt in the Cache Monitor but I haven't found any data.

  • How to fill the application cache by scheduling a Bex report

    Hi Experts,
    I have a Query which take about 4 minutes to execute for the first time and when the same query is executed for the 2nd time it takes about just few seconds.
    I tried using the broadcasting setting in portal to fill the OLAP cache for this query and executed it manually before executing the query in the morning, The Fill OLAP cache has run successfully but apparently the query executing for the first time takes the same time as it was taking earlier. There is not difference even after introducing the fill OLAP cache setting for this query.
    On further analysis I see from the from the "Statistic Data for Query Runtime" that DBTRANS & DBSEL entries are available when the report was executed for the first time, this means the cache is getting filled only when the report is executed for the first time but not through the fill OLAP cache from Portal.
    Can any one please let me know is there any other option available to execute the query before any user executes it, so that the entire report is available in the cache and the user doesn't have any complaints of performance. The report is executed only in Analyzer we do not have any web report.
    Please provide your valuable input to over come this performance issue.
    Thanks

    Hi sam
    You can broadcaste the report... and fill the cache...
    Before setting up the broadcasting settings -- you need to enable the cache property for that particular query or info provider.
    you can enable cache using the RSRCACHE or RSRT transaction ...
    Check the below LInk

    can any one please suggest for the following.
    how to schedule the OLAP chache filling for 3 different queries at a time. do we need to perform this activity individually for three times for three different queries or can we club three queries and do schedule using only one varaint.

  • OLAP Cache for Query Performance

    Hi Experts,
    I have below 2 Questions before we implement OLAP Cache for our Queries:
    1) We have 15 imporatant queries - which do NOT have any variable/selection screen.
    (question here is will it work for those kind of queries which dont have any selection screen/ variant ? ) --> client wants to prime the cache for few queries which dont have variable screen.
    In this case, say if data is later filtered on any CHAR , will it take the data from Cache?
    2) I have a query which initially will have few characteristics in the drill down when we first execute and users would be drilling down on many other characteristics after that. So if I want to fill OLAP cache for this query then what is the best way so that each drilldown in the query gets data from cache.
    Thank you,
    -Su

    Hi Raghavendra,
    Thanks for your response.
    For first Question, Do you mean , even if we do not have any Selection varaibale on Query--we still can fill OLAP cache for it for its all values (i.e. No selection means "*") ?
    If this is the case, then what we need to defile in General Precalculation (Variable assignment) while creating a new setting for the query.
    Thanks,

  • Warming up the OLAP cache

    Hi,
    I would like to schedule execution of some queries in order to put the results in the OLAP cache for fast use.
    Each user run the query with very restricted selection: one period, one node in the CostCenter hierarchy and one currency type! All the selections are obligatory and for single values.
    I created a "super" query with the same characteristics, all in the rows or columns, with not mandatory variables, ...
    I scheduled the "super" query and it create an entry in the OLAP cache.
    When I now run the production query (other query on the same cube, for one node, one period, one currency) the system doesn't use the OLAP cache, but create a new line in the OLAP cache.
    It is impossible to schedule every combination.
    Is there a way to worm up the cache with a different Q?
    Should the seedling be done with Broadcaster or Reporting Agent (in NW2004s)? I think this should be the same ?!
    Any suggestion to fill the cache for my situation?
    Thanks, Tom

    The OLAP cache is at a query level, so to warm up the cache, you must run the actual query that the users will run, not just a similar or "super" query that is similar.
    SDN has some doc on effectively using Global cache which would be good to review.
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/9f4a452b-0301-0010-8ca6-ef25a095834a
    The other key thing to understand is how the setting on variable "Can be changed during query navigation" works.  If this setting is NOT set on your variables, then in order for a query to access the data in the cache, the query must have been run previously with the exact same variable values, as the varaiable values get saved as part of the cached info.
    Selecting the "Can be changed during navigation" variable setting changes the way the system considers the variable - it behaves as a filter.  This has some implications with way prompts for variables appear to the user, so there are user impacts.  In BEx, a variable is normally presented for input when you first run the query and then whenver you refresh it, but when you change the variable setting to Can be changed..., the variable prompt will be presented teh frist time the query is run, but NOT when a refresh is done, it now behaces as if you added a filter to the query.
    So if you change all the variables (or create new ones) used bythe query to Can be changed..., then run your query thru reporting agent or info broadcasting wide open, or with restrictions that encompass all your user's query executions, the subsequent user executions will use the global Olap cache.

  • Pre-fill the filename in Fileupload UI

    Hi,
    I am unable to pre-fill the filename in fileupoad UI.
    When I launch the WD app, on the browser it get the following URL
    http://devai063.private.xxxx.com:8081/sap/bc/webdynpro/sap/zgi_file_upload?sap-language=EN
    at the end I add &filename=c:benefit.txt and hit enter,
    http://devai063.private.xxxx.com:8081/sap/bc/webdynpro/sap/zgi_file_upload?sap-language=EN&filename=c:benefit.txt
    In WD window HANDLEDEFAULT method I am checking for the filename parameter if not empty I am setting the 'filename'  to the context of filename of fileuploadUI, but the app does not show the file name C:
    benefit.txt in the fileupload UI.
    I debugged the HANDLEDEFAULT and I can see the filename but somehow it is not setting to the filname for uploadfile UI.
    any advice is highly appreciated.
    Thanks,
    Ram

    From the online help:
    Technical Browser Details Beyond the Control of WDA
    Due to browser restrictions that are unrelated to Web Dynpro ABAP, the previously entered data path might disappear when a FileUpload UI element is clicked. In newer versions of the browser, it is therefore impossible to enter the file name in the entry field. The field always remains empty. The selection of the file name is therefore only possible in new browser versions using the Browse... button. You cannot enter the file name manually (using the keyboard or the Copy and Paste functions) or by setting the file name from the back end (directly or using context binding). For more details, read the security-related information in Internet Explorer 6 about handling <input type=file>.

  • I want to pre-fill the report

    I have some reports that are similar but are to be run according to sales rep. As I am in the process of doing this more automatically via email 'bursting', but in the meantime, they need these reports. So i am created one report for each rep. I would like to at least pre fill the rep name as report parameter and to use in the headings at the least. I put in one rep name as the default but it does prompt i would like this to run without the prompting having the name as it does. how do I do this?

    hi Paul,
    please see how to set up your reports readying them for a publication in this guide.
    you need to create a dynamic recipients list as per page 6 (using another report which is essentially a list of emails, names, etc.) as well as looking at the Personalization section. the personalization is what you've done already with the rep name as the prompt.

    refer

  • Problem while filling the Setup Table for the DS 2LIS_02_SCL.

    Hi All,
    When I am trying to fill the Setup table for the DataSource 2LIS_02_SCL and only for one specific Purchase Order, it is showing me a message like
    u201CDataSource 2LIS_02_ITM contains data still to be transferredu201D
    I have deleted the Setup Table and I want to delete the entries from SM13, but I do not have Authorization.
    Also, here I am trying to fill the Setup Table for 2LIS_02_SCL and not for 2LIS_02_ITM, but the message displayed above is showing as 2LIS_02_ITM DataSource. I think the Setup Table will be same for both the DataSources.
    Waiting for your valuable inputs.
    Thanks in Advance.

    Hi,
    When you want to fill the setup tables first you need to delete setup tables to avoid the duplicate entires in setup tables ( you can delete the setup tables by using t.code LBWG with application no is 02)
    In your case, the data souce is 2LIS_02_SCL for purchasing.
    when you want to delete the setup tables by using t.code LBWG with 02 application no it will delete all the purchasing related data from all the data sources like
    2LIS_02_SCL
    2LIS_02_ITM
    Before the deletion of setup tables you need to clear the delta Queues and stop the V3 jobs, which loads the data to Delta Queues (RSA7) and Update tables(LBWQ).
    you need to run the V3  jobs manually by using LBWE > Job control > and schedule the jobs until the delta queues will get 0 records. that means no data will be available in RSA7 and LBWQ
    go to SM37 to see the jobs LIS-BW-VB_APPLICATION_02,
    once the delta queues gets 0 records by running V3 Jobs manullay.
    Then remove the released state jobs > remove from schedule means delete the jobs in LBWE > Go to job control > you can delete the released jobs.
    Becuase No postings to be done in application tables, while running setuptable filling you should take some down time to fill the setup tables.( OLI*BW)  *=Application number.
    Once you clear the Queues and delete the v3 jobs, then you need to fill the setup tables after deletion of setup tables.
    once you fill the setup tables , by running intialization to BW side the delta Queue is formed for the data source in R3 side
    Now the postings can be done in R3 side, so you need schedule back the V3 jobs, which you already delted from LBWE to load the data from application tables to RSA7 or LBWQ.
    I hope this may help yoou.
    Regards.

  • No measures found in the OLAP catalog for user CS_OLAP

    Working in XP, with Oracle Database 10g 10.2.0.1.0, AWM 10.2.0.1A, JDeveloper installed from the 10.1.2.0.2 Developer Suite, BI Samples are 10.1.2.0.0)
    I'm receiving this error when connecting to the CS_OLAP schema through JDeveloper:
    "Warning: No measures were found in the OLAP catalog for user CS_OLAP; therefore, you will not be able to create OLAP queries with this connection."
    From the top...
    I've installed the sample databases (oe, pm, sh, etc..) from the Companion CD. The SH schema (required for installation of CS_OLAP) is present.
    I've executed install.bat from the ...\common_schema directory. It creates the CS_OLAP tablespace and user. There are no errors in the log file. It appears to be building the datafile. When it finishes, Enterprise Manager shows the CS_OLAP tablespace using 87% of its 325MB allocation.
    In Enterprise Manager, there are a total of three tables listed for the CS_OLAP schema. They are: AW$AWDEBUG, AW$SHAW, and AW$UTILS. There are no "regular" tables listed, just these three Analytic Workspaces. I open an OLAP Worksheet in AWM, and I can execute AW ATTACH CS_OLAP.SHAW FIRST RO, and see all of the objects in the AW. They are populated with dimension values and data. It's a full blown AW.
    I then installed the BI Beans sample applications. Again, no problems during installation.
    I opened JDeveloper, drilled on the BIBEANS sample workspace, opened the CATALOG project, and checked the connection settings for the catalogBIDesigner. The TEST of the connection was successful, but I received that warning message. The 'Presentation 1' crosstab returns no data, only the little default table. Basically, the system can't see any data in the CS_OLAP schema.
    So, an AW has been created for CS_OLAP, it's populated with dimensions and data, but JDeveloper doesn't see the contents.

    Nevermind.
    The answer is found in the version of the BI Samples zip file.
    BI_10_1_2_1_0_samples.zip works just fine.
    BI_10_1_2_0_0_samples.zip didn't.

  • Taking long time filling the setup tables for sales and shipment

    Hi ,
    I am trying to fill the setup tables for sales and shipment and it is taking lot of time .
    It took 16 hours just to bring 6 months of  sales history  data in the test environment .
    Cn anybody help on this issue why it is taking that much of time ...
    I am trying to  load the sales data from R/3 into APO-BW from 2005 to 2007 .......
    It is taking 16 hours to fill the data for only 6 months .

    Hi,
    1. delete data and refill the setuptables again by spliting to several small pieces.
    2. compare the data. wht is the last Document numner in RSA3(Maximum one). Start from Maximum one. may be bit complex approch.
    you need to check with PSA and base tables.
    keep one thing in your mind you need to check againest MSEG and BSEG only. noy BKPF and MKPF.
    correct if i'm wrong.
    either refill or create a user exit to avoid duplicae records(you should have very good understanding of data, it will lead to inconsitent data for delta records).
    User exit not a good solution. it's one possibility.
