How to create Virtual InfoProvider with Services - Virtual Characteristic

Hi all,
I need to create a virtual infoprovider that also fills a virtual characteristic in order to display custom characteristics and calculated values based on user selection.
Basicaly what I want to do is send a variable in a virtual characteristic equal to the values I want to fill in the characteristic.  So for instance if my base cube contains the infoobjects Brand, Product Line, Region and Country I want a  have a new infoobject that has no data, but fills itself with the vales of the infoobject I specify at query time on the virtual cube.
The reason for this is I am trying to create a WAD using the delta chart (waterfall graph) that will show the difference between the plan and actual totals for a specific characteristic in Profitibility analysis.
I have a document that explains the situation.  Send me your mail address and I will send you the document.
Kind Regards

We found a way to build the structure for this.
Regards

  • Difference between General remote cube and virtual infoprovide with service

    Hi guys,
    I could not understand the difference between general remote cube and virtual infoprovider technically. And I could not find the document about how to set general remote cube.
    I only find the following sources.
    http://help.sap.com/saphelp_nw2004s/helpdata/en/23/c0234239f75733e10000000a155106/frameset.htm
    "In comparison to other VirtualProviders, this VirtualProvider is more generic. It offers more flexibility, but also requires a higher implementation effort.".
    I am welcome your lecture. Especially I would like to know how to set general remote cube..

  • Virtual infoprovider with services - Navigational attributes

    Hi all,
    I have a basic cube in BI system- X , and created a virtual cube in another BI system Y with services to read data from basic cube of BI system X . In BI system Y we built a report on virtual cube. This report (on virtual cube in BI system Y) is using a characteristics say Product group ( which is a navigational attributes of prodect in BI system X).
    DataFlow is as under:
    Basic cube in BI system X:
    Product
    Year
    Amount
    and Product group is switched on as navigational attributes in this basic cube.
    Virtual cube in BI system Y:
    Product group
    Year
    Amount
    Report in BI system Y:
    Product group in rows
    Amount in column
    This report is not working.
    If I do the the following changes as follows then it works:
    1.Use Product instead of product group in report
    2. Switch off navigational attributes in basic cube.
    We are in BW 3.5 and navigational attributes option is ticked on for virtual cube.
    In summary, If I do not use navigational attributes in report and switch off navigational attributes from basic cube then report shows data.
    Could you please help me to figure out the issue.
    Thanks,
    Harry

    Thanks Naga,
    Yes, I tried adding product in virtual cube as well but it did  not work. Secondly, we do not want to add product in virtual cube because of data aggregation.
    Most strange thing is that, once we switch on any navigational attributes on basic cube, function module stop working (paasing any data to virtual cube report). report says no appropriate data found. We are using sap standard function module "RSDRI_INFOPROV_READ_RFC". I debegged this code and no data in internal tables.
    If we switch off all  navigational attributes from basic/source cube this function module provide data to internal tables in code.
    Why function module is behaving like that.
    You guys experience/support/any clue will be appreciated highly.
    Thanks,
    Harry

  • Virtual InfoProvider with Function module, how to u0094bypassu0094 OLAP memory

    Hi
    I have created a Virtual Infoprovider with services as described in the How to… Implement a VirtualProvider with Services (SAP NetWeaver 2004s). It works and I have even been able to make some special calculations within the code. But how do I make sure that the OLAP engine always fetches data from the source table eg when drilling or filtering in the front-end? I have disabled the query cache but I also need to disable the OLAP engines own cache / memory how do I do that? I need the functionality as the implemented calculations depend on the overall report result and they must be calculated before aggregation.
    Hope that you can help
    Kristian

    Hi Deepu
    As I wrote, I have allready set the cache Mode to "0 Cache is Inactive". But this is the the general data cache i.e. reuse of data among users this is not deep enough. I need to make sure that each and every query step goes to the DB for new data.

  • Report issue on Virtual cube with services

    Hi,
    I'm following a how-to document to report on a virtual cube using a custom function module and everything seems to be OK except it is dumping at the following line which is included in the How To document "How Tou2026Implement a virtual InfoProvider with Services".
    Both <l_s_data> and E_T_DATA  are of same data types as discussed in the how-to document.
    append <l_s_data> to E_T_DATA
    These are the declarations which are same as HowTo document
    E_T_DATA TYPE  STANDARD TABLE
    FIELD-SYMBOLS: <l_s_data> TYPE ANY.
    Did any one face this issue. Greatly appreciate any insight into this issue. We are on BW 3.0B.
    the dump i'm getting is ...
    Data objects in a Unicode program are not convertible.
    Error analysis                                                                               
    The statement    "MOVE src TO dst"   requires the operands "dst" and "src" to be comvertible.                                                                             
    Since this statement occurs in a Unicode program, the special  convertibility rules for Unicode programs apply.

  • InfoProvider with services

    I am playing with creating Virtual cube with services from the document How to Implement a virtual infoprovider with services
    I created the Funtion module in R/3 system but got stuck at step 7. I have never worked with FM.  What are the things your write in the import tab and export tab for that particular example

    Hi,
    Maintain the same parameter names and values associated in step 7&8 as shown in the figure.
    Import :- you specify all the variables or parameters used in function module. the values for these parameters are passed from external programme and in this example BW must send InfoProvider name, . .etc parameters given in the picture.
    Export are the parameters exported from this function module to the external programme in this case Data and other parameters are returned to BW.
    Hope this helps.
    Thanks,

  • How to load data from a virtual cube with services

    Hello all,
    we have set up a virtual cube with service and create a BEx report to get the data from an external database. That works fine. The question is now:
    Is it some how possible to "load" the data from this virtual cube with service (I know that there are not really data...) into an other InfoCube?
    If that is possible, can you please give my some guidance how to set up this scenario.
    Thanks in advance
    Jürgen

    Hi:
    I don't have system before me, so try this.
    I know it works for Remote Cube.
    Right Click on the Cube and Select Generate Export Data Source.
    If you can do this successfully, then go to Source Systems tab and select the BW. Here, Right CLick on select Replicate DataSources.
    Next, go to InfoSOurces, click on Refresh. Copy the name of Virtual Cube and add 8 as a prefix and search for the infosource.
    If you can see it, that means, you can load data from this cube to anywhere you want, just like you do to ODS.
    ELSE.
    Try and see if you can create an InfoSpoke in Virtual Cube. Tran - RSBO.
    Here, you can load to a database table and then, from this table, you can create datasource, etc.
    ELSE.
    Create query and save it as CSV file and load it anywhere you want. This is more difficult.
    Good luck

  • How to Virtual cube with services works

    Hi,
    How to Virtual cube with services works.
    can anyone provide me a realtime scenerio.
    if possible provide some code.
    Thanks,
    cheta.

    For which functinality you are trying to create VC with services.
    This is mostly used in SEM BCS.
    You have to create cube similar path like normal cube, but select in the properties virtual cube, services.
    There is a standard FM which connects the Virtual cube to the required cube in BCS. ( this is done by BCS data basis generation function) and we have to do nothing for FM.
    In BCS we use virtual cube only for reporting purpose, since standard BCS cube cannot be used for reporting. hence what we do is create another virtucal cube very smiliar to BCS cube.
    Then both the Virtual cube and BCS cube are connected by standard FM.

  • Virtual infocube with services - division of suppliers in categories

    Hello,
    I’ve a problem and the idea to solve it with a virtual infocube with services. But unfortunately I don’t know if it’s really possible to solve it like this.
    The scenario is:
    I’ve suppliers, turnovers, goods (which have been delivered) and different quality deficiencies.  In dependence of the turnover with each supplier, they will be ranked. For the position in the ranking they get points. From this start points one have to subtract points for the different quality deficiencies. In dependence of this end-sum, the suppliers will be divided into categories. And this division should be shown in the query.
    But the suppliers can vary in each run of the query in dependence of the selection in the query. And the turnover of each supplier which depends on the selected goods can vary, too. So the division into the different categories depends on the selection and is dynamic. One doesn’t know this before. And so it isn’t possible to save the category of each supplier in an infoprovider.
    Now I want to know, if it’s possible to solve this with a virtual infocube with services.
    I hope there’s somebody who can help me. Thank you.
    Susanne

    Hello Susanne,
    first of all, yes, it can be solved with VirtualProviders. But I wouldn't expect it to have a good performance. It depends on the number of data records we are talking about.
    When you create a VirtualProvider you should make sure that the RFC Packing switch is flagged on. You can then get the selections in the tables-parameter selection with the structure bapi6200sl. Now you need to read the raw data for your selection. Either use the function module RSDRI_INFOPROV_READ or write the data into an ODS to simplify the selection.
    Based on the raw data you need to do you calculation and write the data back to the table data.
    For details of the implementation of the VirtualProvider and the function module you can check the SDN. These topics are also covered in my book ABAP Development in SAP BW - User Exits and BAdIs that was lately translated into English. You can find both the German and English version under <a href="http://www.sap-hefte.de/katalog/hefte/titel/gp/titelID-1256">www.sap-hefte.de</a> or <a href="http://www.sappress.com/product.cfm?account=&product=H1948">www.sappress.com</a>

  • Virtual InfoCube with Services - function module parameters documentation ?

    Hello,
    I have been trying to use a Virtual Infocube with Services.
    I have seen most of the posts in SDN, and read the documentation in http://help.sap.com/saphelp_nw04/helpdata/en/8d/2b4e3cb7f4d83ee10000000a114084/frameset.htm
    I did not manage to find a precise description of the import 
    parameters of the Variant 2.
    In particular, what is the meaning of the
    i_tx_rangetab TYPE rsdri_tx_rangetab parameter. I read in the code of RS_BCT_FIGL_DATA_GET that it has to do with query columns. In the tests I did this table is alway empty.
    Also, i_th_sfc gives you the list of characteristics used in the query. But it does not inform you on wether these are in the 'rows' 'free characteristics' or 'filter'. Is there a way of knowing that?

  • Error after transport of Virtual Cube with Services

    Hi All,
    would any body can suggest me how we can change the source system assignment in QA or Production client for virtual Cube with Services.
    A virtual cube is created with Services using the settings for RFC and using the logical source system. however after transporting the same to the QA system the Logical Source System has not changed and thus it is giving error " Error occured while determining target system for the logical system" would any body can suggest me how i can change the logical source system assignment in QA system for Virtual Cube with services.
    Points would be rewarded appropriately.

  • Virtual provider with services

    Hi experts,
    we have the same query on virtual cube(with services) and BW loacal cube.Both local cube and virtual cube contains the same data. But both are showing different query results.
    that is virtual provider query is not displaying all the values in master data table.
    for example we have 10 brands under one company code, the virtual cube query is only showing 5 among them. I would like to see all the values without any restrictions, so can you please guide me.
    when i checked from tcode /listcube it is displaying all the values without any restriction.
    Thanks for your time.

    Hi Anupama,
    My question is if u have same data in the both cubes ( virtal&Basic) u can create querry on u r basic cube only. But this not answer.
    R u using same conditions on both cubes. Means In querry designer.
    When u r using the virtual cube(with services) it is generally create on function module, this module properly maintainning the complete master data or not? Check it.
    Hope this will help

  • What is the use of Data packet dim with Virtual cube with services

    Hi Friends,
    Could anybody tell me what is the use of Packet dimension in Virtual cube with services , It cannot contain data persistently ,Just fetch at runtime,Then there is no Physical load happening,Then why it should be automatically created for this??
    Message was edited by: Pradeep choudhari

    Hi Maik,
    Unit dimension will not be created automatically until and unless you have keyfigure referning units..
    But my question is : Why should we have data pack dimension , which is useless in this case of Virtual cube with services.It should not be created automatically!! What do you say??

  • Virtual Cube with Services - Debugging

    I want to debug the function module assigned to a Virtual Cube with services. Using transaction RSRT, I can access the FM using debugger when the query is initially called, by selecting Debug options/Default Breakpoints/VirtualCube. I want to debug subsequent navigation steps on the query. How do I access the debugger for subsequent navigation steps?

    Hi Maverick,
    You can extract the attributes of the characterstic but u need to configure depending on the function module you are using to read the data from basic infocubes.
    I suppose in your FM u are using RSDRI_INFOPROV_READ*(check in your FM to find this) in to get the data from basic infocube. If it is the case then u need to configure interface parameter I_TH_SFC and I_T_RANGE to get the attributes. Hope it helps and if need more let me know the same. If you are using the other function modules you can follow the same logic.
