Time awareness of cnanging dimensions members

Hi
ssas changing dimensions are using startDate and endDate attributes to add relevant time range for thier members. 
so when slicing time dimension only those who are relevant to that date are visible.
I understand support for this interaction is dependant on client?
If so which clients are known to support it?
Do excel pvt tables, power pivot or power view or ssrs 2008 r2?
Any other you know for this matter?
TIA!

no worries - we'll get there eventually ;-)
so the users want to analyze members in a SCD-Type2 dimension based on the date/time the members were active (regardless of whether the members were associated with a fact).
To do this, you would need to create a new measure group in the cube based on the Type2-dimension. This new measure group will likely only have a single measure (count of rows) and will be related to the following 3 dimensions:
Date: representing start date (role-playing)
Date: representing end date (role-playing)
Itself: the existing dimension based on the same table
Some recommend creating an additional factless fact table, but that's not necessary w/ SSAS.  
FACT_PRODUCT_CHANGES
  ProductKey --> DimProduct
  StartDateKey --> DimDate
  EndDateKey --> DimDate
By the way, this is discussed in more detail in Chapter 8 of Star Schema: A Complete Reference

  • How can I manage access to dimension members in a layout?

    Hello,
    I have a dimension member list of materials (400) on a "material" dimension. But some people have access to one portion of the whole group and others may have access to other groups. But the materials can be shared between groups so I cannot group them in differents hierarchies.
    The problem is in the layout you need to select a hierachy to show various rows (the whole group of materiales). The layout shows all the list of materials. Even if the user only have access to 10 of them. I don't know how is the best way for presenting this to the user? It should presents only the 10 rows corresponding to his materials.
    One way that I found (but I don't find it acceptable because of the hard effort that represents the maintenance) is to create differents member access profiles and denied the access to each material (dimension member - 390) that the user cannot modified. Then in excel I have to run a macro that hides all the rows that have an empty description in the cell of the material name.
    How can I achive this?
    Is there a function in BPC to see if a user have access or not to a dimension member?
    The only way to show in a layout various rows is to set in the view a hierarchy?
    Thanks & Regards

    hi
    pl. verify whether this will suit your requirements:
    Material           UG1           UG2
    MAT1               Y
    MAT2                                 Y
    MAT3               Y
    MAT4                                 Y
    MAT5               Y               Y
    Now UG1,UG2 diff user groups and property in Material. Assignment of Y is one time job.
    At the time of accessing the dimension members can restrict on the basis of UG1="Y" or UG2="Y" property
    Here MAT5 is common in both UG1 and UG2
    (Hardly may have 3-4 set of users: Accordingly can have UG1,UG2,UG3,UG4 etc.)

  • Import Comments data and Dimension Members from csv file via Data Manager

    Dear Experts,
    I have two questions regarding the data manager.
    Q1.Is it possible to import "Comments" from the csv file via Data Manager?
    We'd like to import the amount with "Comments".
    My image of csv file is like below;
    ACCOUNT,CATEGORY,TIME,ENTITY,INPUTCURRENCY,AMOUNT,COMMENTS
    1100000,ACTUAL,2010/06,LC,30000,This is comment
    Q2.Is it possible to import the dimension "members" from the csv file via Data Manager?
    We have a user-defined dimension named "Project"
    and would like to import the members, instead of maintaining them in BPC administration manually.
    I found an online help information which says "Import Master Data from a Data File Example",
    but I could not find any relevant sample package for this.
    (I tried to import the members by using "Import" package, but it failed...)
    reference:http://help.sap.com/saphelp_bpc75/helpdata/en/86/8b1bfc12c94fb0b585cca70d6f1b61/content.htm
    Thanks in advance for your help.
    Fumi

    Hi Fumi,
    In this case, I would suggest you to create a customized SSIS package which will fill-in the "Comment<APP>" table, according to the csv file you have. I do not know any standard package that allows you to import comment the way you would like...

  • Not able to delete any Entity Dimension members

    Hi All,
    I am trying to delete some Entity Dimension members but its not allowing me to delete. This problem is only for Entity Dimension.
    I can edit Entity member name or properties successfully but not able to delete or move the position.
    I also tried to check member usage but its not giving me any results, a blank screen comes and planning goes down after some time. Same happens when I try to delete any Entity member.
    I have admin rights on Planning and I can delete other dimension member but not for Entity. There is no workflow started for Entity but If it is than also it pop-ups that after member deletion all planning unit will be lost. I have bounced planning DB and also restarted all Hyperion services but still no luck.
    Please let me know if anyone has faced this issue or have any solution to resolve.
    Regards
    Vishal

    Hi John,
    After uncheck of "enabled for process management" for all Scenario along with Version dimension members , this issue is now resolved. But its a temporary resolution as client has not yet started any workflow so we can uncheck that options ,but when they need to start workflow process then we have to check this options again which will start this issue again.
    Do you have any permamant resolution for this issue?
    Thanks for your help.

  • Issue while Maintaining Dimension Members

    Hi Gurus,
    I have upgraded my MS Office from 2010 to 2013. Below is the screen shot of my MS office version.
    Now issue is I am not able to maintain dimension members. Every time we click on a "Maintain Dimension Members" nothing happens. It was working fine while I had 2010. We are at the latest service pack (BPC MS10.0 SP16).
    Not able to figure out what is the issue as I don't get any errors.
    Any Idea?
    Thanks,
    Charly

    Hi Charly / David,
    Please review Note 2040480 - Limitation of maintaining dimension member in BPC Administration
    [Workaround]
    To avoid this issue, users should close Microsoft Excel before managing the dimension member in SAP Business Planning and Consolidation for Administration client.
    If the issue persists:
    1. Close BPC Admin
    2. Open Windows task manager and end all Excel.exe processes
    3. Open Excel, )standalone) to see if there is a prompt or user action. (usually an error stating that Excel crashed due a plugin/error, Do you want to disable this plugin Yes or No)
    4. Click no the prompt (or yes depending on the message).
    5. Re-open BPC Admin and try to maintain dimension members
    Does that work for you?
    I have been successful in using Excel 2013 with BPC 10 to maintain dimension members.
    Thanks,

  • Sorting Attribute dimension members

    Other then reloading attribute dimension members in a different order. Is there a possbility with ODI or the SortMember.cmd utility to perform such a task?
    I ask since I know presently while reloading the attribute dimension with ODI it drops the latest member to the bottom. This is not the order I need it in. I tried to mess with the load in ODI and still no fix. I tried to use the SortMember and it only appears to work on all dimension but currency, period, and years as it reads in the planning admin guide. This is for 11.1.2.1.
    Does anybody have any input? If so please reply.
    Thanks,
    DjSmeadly

    It is one area that has never been addressed so sorting attribute members is not so easy, as far as I aware the sortmember utility does not work on attribute dimensions.
    Cheers

  • Deleting dimension members

    We have an AW with cubes refreshing every day. Fast solve of these cubes with incremental set of data finishes usually within an hour or two.
    Our recent requirement needs for us to remove some old facts as well as a few dimension members. The facts can be cleared but we noticed that deleting dimension members (using synch load) is causing a full cube solve due to changed relations. With the amount of data existing in this AW, full solve takes about 2 days to complete. Deleting dimension members for which we never ever loaded any facts also causes the same result as above.
    I was wondering if there is any way we can delete these dimension members without triggering a full cube solve.
    Another question is if it is possible to update dimension primary keys inside of the AW?
    Any help is really appreciated.
    Database Version 11.2.0.3

    These types of questions have been answered in the past by David Greenfield.
    There are two ways to delete a dimension member through commands.
    (1). OLAP dml command "REMOVE_DIMENSION_MEMBER"  explained here:   http://docs.oracle.com/cd/E11882_01/olap.112/e17122/dml_commands_2042.htm#OLADM2692
    OR
    (2). dbms_cube.build  command: 
    exec dbms_cube.build(q'! "TIME" USING (DELETE FROM DIMENSION WHERE MEMBER = 'APR-2011') !');
    Take a look at this old post, where David Greenfield explained it.
    https://forums.oracle.com/message/9426946
    There is no way to rename a dimension member in a standard-form analytical workspace.  There is  "MAINTAIN RENAME" olap dml command, but it will not work with dimensions created through AWM.  You can add the new dimension member, then copy cube data associated with old/existing member to the new member and then delete the old member.
    For cube copy data example, take a look at these old (15-Feb-2011, 16-Feb-2011 and 17-Feb-2011) posts by David Greenfield:

  • Reg:Dimension members

    Hi Experts,
                        In my scenerio i have to allow the user to plan for 24 months and at the end of the 12 months he might come back and do the budjeting again for another two years.Both they call it as same name as budjet.
    Can anyone suggest me how to proceed the dimension members to acheive this scenerio?
    Budjet           April 2010          March 2012
    Budjet          April 2011          March2013
    Regards,
    Vinoth Kumar

    Hi Vinoth,
    As nilanjan told,
    Category Dimension --> Budget (Member)
    Time Dimension --> April 2010 till March 2013 (24 Months) can be used. 
    You can use the same category "BUDGET" since the time dimension member is different in this case.
    For eg,
    they are stored as line item,
    Entity          Category     Account              Time
    A100      Budget        C1111     April 2010
    A100      Budget        C1111     April 2011
    are stored as two different line item.

  • Looking for BPC user contacts with large numbers of dimension members

    I would like to make contact with other BPC users that have multiple dimensions with dimension members in excess of 10K.
    Thanks,

    Hi Helene,
    With 3,000 members you should not be experiencing these problems, if your report is designed properly.
    I'm running BPC 5.1 SP8 on SQL 2005, with a dimension containing 22,000 members. Client PC's are typical (XP, Excel 2007, 1 or 2 gig RAM).
    Using EVDRE and this dimension expanding on the rows, most reports & input schedules can expand & refresh in the range of 10 to 30 seconds.
    The faster times are when I use a row expansion memberset using dimension properties, such as Active="X". The slower times are when the memberset is hierarchy-based, such as BAS.
    If you're using a dynamic template (one using EVEXP for the expansion) then you should start over using EVDRE. It will be much faster, particularly if you optimize your row expansion.
    It's often a good idea to add dimension properties specifically for the purpose of optimizing the report expansion, if the dimension has thousands of members. I sometimes go as far as to add properties which mimic the hierarchy (MyLevel2, MyLevel3, etc) just for this purpose.

  • Duplicate Dimension Members

    Hi All
    When I am processing the Entity Dimension, am getting an error "DUPLICATE DIMENSION MEMBER %1 IS DETECTED".
    But I had checked so many times there is no Duplicate Members (%1) in Entity Dimension worksheet.
    Please help me on this issue.
    Thanks in advance
    Thanks

    Hi Nilanjan
    Yes, It is only for Entity Dimension.
    As you have mentioned in your previous mail I tried the same.
    I deleted all the members of the Entity Dimension and then I process the Empty Member sheet.
    While Processing the Dimension still I am facing the same error "DUPLICATE DIMENSION MEMBER %1 IS DETECTED".
    Help would be highly appreciated.

  • Essbase export with a "string" appended with all account dimension members

    Hi Everyone ,
    can any one please suggest , how i can do my essbase export with a string appended with all account dimension members.
    i have tried more options but it doesn't looks working. i tried it by report scripts using RENAME function , but it works for 1 member at a time..
    please suggest !
    thanks
    Edited by: Vivek on Jun 19, 2012 6:55 PM

    Hi,
    If you're looking for the ability to append different strings, then you should probably be looking to an external process.
    If you're looking to append the same string, I can think of one way. Make your report script fixed-width (that way you always know which character in the line you're changing) and then utilize the MASK command. (you can find it in the Tech Ref under Report Commands)

  • Valid Combinations for DImension Members

    Hi All,
    We have dimensions for Cost Center and Company code in one of our BPC Applications..Is there a way we can avoid users planning for incorrect combinations?
    E.g. -
    Valid Combinations  -
    Cost Center 1 >>>Company Code 1000
    Cost Center 2 >>>Company Code 2000
    In case the user selects Cost Center 1 & Company code 2000 in current view and enters plan values - the system should not allow the same...Is there a way to maintain valid combinations for dimension members (belonging to different dimensions) in BPC???

    Hi Shibu,
    It was just an example, to show you how to control the combinations. You might have to design it based on the exact business requirement.
    Please note that this wont be a straight-forward process, and you might have to use some VB macros to ensure you get, what you require.
    Lets say, based on the expansion, you have 5 company codes to be displayed in the template. You should, first, use an EVEXP function to list all the 5 company codes in some empty region of the template. Use a macro to concatenate all the 5 company codes separated by "|". Then, for the expansion on cost centers, you should again use a macro which will consider each of the 5 company codes at a time, and set the expansion to "P_COMPANY = ABC". Since you have 5 company codes, hence you will have 5 such combinations of member filter pertaining to each of the 5 company codes. Then you must concatenate them using "|", and this should be the memberset option for the cost center dimension.
    I understand that this is going to be a bit complex, but I dont see any other option.
    Hope this helps.

  • 7.5 NW: Uunable to delete dimension members from the entity dimension

    Hi,
    I would really appreciate a solution to this. We are planning on implementing an IFRS consolidation using the SAP IFRS Starter Kit. We have created a copy of the IFRS Starter Kit, without any data. In order to customise it for our purposes, we have decided to keep the sample dimension members in Accounts, Flow and AuditID but delete the data in other dimensions. We have managed to delete the sample dimension members from the Time,  Inter-company and Conoscope dimensions but are unable to do it for the Entity and RateEntity dimension.
    Can anyone please explain why this is happening? There is no data in the application and so, why is this happening? We are on Service Pack 5.
    Many thanks in advance.

    Hi,
    Before going into the BPFs, i am sure you would have already checked, I would do the following:
    -Try to process the entity dimension in offline mode. I have seen this happening with some dimenions  that i know there is absolutely no transaction action. Just check processing the entity in offline mode. Do not untick 'take the appset offline'.
    - You would have done this. Double check for the transaction data.
    - Regarding BPFs, its not easy to check this. we had this situation earlier. Please go into the backend and in se16 you will find all the BPF tables with UJB*
    There would around 10-12 such tables. Have alook in them. Not all tables need to be looked into. But please have a check there.
    - Also check if entity has been referenced to any other dimension. Its good to check if you have INTCO dimension to see if it is referenced there.
    Thanks,

  • Using intersection of dimension members in a SINGLE column/row name

    I need help understanding how a single row/column name in a report can be populated with an intersection of two different dimension members of an Essbase cube (ASO). For example, suppose I have two dimensions members in my cube - Sales and Qtr1. Now I want to create a single column-name in my Smartview or FR report called "Sales in Qtr1" that would store values for Qtr1->Sales. Also, i want to have a single column name such as (Qtr1->Sales % Qtr2->Sales).
    Is this done via a report script or some other method?
    My report would look as follows:
    Sales in Qtr1 | Sales in Qtr2 | Qtr1 Sales as a percent of Qtr2 Sales
    Region1 100 | 200 | 50%
    Region2 25 | 100 | 25%
    Would appreciate any guidance.
    Thanks.

    Getting the data the way you've described is really easy, just nest the dimensions in Excel (or whatever reporting tool), one dimension over the other.
    It's the same for rows as it is columns (okay, in rows instead of columns).
    Essbase is very good about doing asymmetrical reports. Take a look at the DBAG and scroll down for the section labelled "Generating Symmetric Reports" -- the second example shows a asymmetric report.
    Making the label one cell? A bit hard in Excel -- you'd have to create separate retrieve ranges and report ranges or play a game with hiding rows. Very easy indeed in Financial Reports -- you basically hide a row and put whatever custom label you want in the dimension that remains (technically speaking you could hide both rows and do this with a text row -- whatever you prefer -- but I've generally seen this with the former technique.
