Can we precompute a value based dimension ?

Hi,
I do not know how to precompute/summarize a value based dimension in AWM 10g.
One of my value based dimension in AWM 10 g (10.2.0.3A) showed pre-compute already done , but the aggmap of the cube did not show any precompute clause in relation statement for this dimension.
1) Is AWM 10.2.0.3 A taking care of this internally ? How can i verify this ?
2) If not, how can i set pre-compute for a value based dimension by hand ?
(provided the precompute clause remains even after cube is maintained).
Regards
Chakri

Hi All,
Thanks for your replies.
Let me give you a background . Iam creating a cube over some value based dimensions in OWB (10.2.0.3) and then deploying them to AW .Iam loading the cube and dimensions using OWB mappings.
Any other changes or objects not possible through OWB are done directly in AWM (10.2.0.3A)
Stuart,
Yes this a duplicate thread i posted for almost the same problem statement.
David,
1st option - precompute valueset is defaulting to all members.
a) Are you talking about the valueset <DIMENSION>_PARENTREL(<VSET>)
I did an rpr on <VSET> , it just returned the hierarchy name. This vset would be there for any dimension ( even without precompute) and would just return the default heirarchy
b) or Are you referring to PRECOMPUTE(<VSET>).
As mentioned, this VSET is not coming up in the aggmap.
2nd option - Modify the XML template with the PreComputeClause to say Expressiontype="INCLUDE" instead of "EXCLUDE". You can then delete the cube and recreate it from your XML.
The Model view of AWM (10.2.0.3A) was showing the 'All' box as checked for this value based dimension, but the aggmap did not show any PRECOMPUTE clause. Also, when i checked the XML of the cube (in which the dimension is used), there was no pre-compute clause for only this dimension. This might be due to my AWM version iam using.What is your AWM version ?
How do i check if pre-compute is working ?
Here is the info about my cube :
Dimensions : TIME (Levels: Year,Quarter,Month) ,LOB,CUST and FIN
All dimension except TIME are value based.
Settings : compressed, partitioned along TIME.MONTH
I want to fully precompute TIME and LOB .
CUST and FIN should not be precomputed.
Thanks

  • DimensionmemberList with value-based dimension

    Hi,
    I'm unable to use a DimensionMemberList with a value-based dimension. It works fine with level-based, however when I select a value-based dimension and hierarchy in the wizard and click on "Next" an Error pop-up appears with no message and I have to click on "Cancel" to get out of the wizard.
    Has anyone encountered this behavior?

    Hi Ankita,
    As per my Understanding the VP column did't map to any LTS .
    When ever u have multiple LTS in Dim Admin tool won't create Dimension Hierarchy manually we need to create that.
    Follow these steps to resolve your Problem...
    1) give the simple join in physical layer for that two tables.
    2) Create one Dim table in to BMM layer drag all columns in 2 tables in to BMM Dim table so u can able to see all the columns is mapped in to their respective LTS.
    3) Now u can create hierarchy manually step by step.Like Grand total Parent ----> Child level .
    4) If u have any fact table joined with these dimension in physical layer give the logical joins in BMM layer and set the content levels properly.
    Let me know need any detail clarification.

  • Value based dimension hierarchy in OBIEE 10G

    Hi,
    I am a user of OBIEE10G. I have to create a value based dimension hierarchy in my RPD. My hierarchy should be such that when I click on any VP Name, the respective employees working under him/her should be shown. But my columns of VP Name and Employee_Name are present in separate dimensions. Hence when I drag the column of VP Name to Employee dimension and then create the dimension hierarchy, I get an error of illegal cross join .
    Is value based hierarchy possible in 10G?
    Pls reply.

  • Pre-compute for Value based dimensions in AWM 10g

    hi,
    I created a compressed partitioned MOLAP cube in OWB 10.2.0.3 based on some value based dimensions.
    I selected the hierarchy in value based dimensions for pre-compute, but it did display the hierarchy in OWB.
    I deployed the cube into Analytical workspace AWM 10g(10.2.0.3A).It created PRECOMPUTE(NA) in the relation statement for the value based dimensions.
    Is it that value based dimensions cannot be pre-computed (at the heirarchy) in AWM 10g ?
    Regards
    Chakri

    For reference, I believe this error was due to the deletion and recreation of a standard form AW formula without full restoration of the formula's PROPERTY values. AWXML (and hence 10g OWB/AWM) will not work correctly if you remove PROPERTY values from objects.

  • Has anyone setup BIEE with OLAP 10g using value-based dimension hierarchies

    I just wanted to know if it is possible to setup BIEE with 10g using multple dimensions containing multiple value-based hierarchies?
    I know this involves using the OLAP Cube View Generator to create an sql view of the cube data.
    I have been able to get this to work with nine dimensions all containing a single value-based hierarchy bar one which had four value-based hierarchies. But as soon as i have multiple hierarchies in multiple dimensions it seems to go haywire and i cannot get the sql view to return correct data.
    I thought i would post on the BI side to see if anyone has been successful in creating a BIEE setup like this?

    The simple answer to your question,
    how robust is the 11g materialised views with multiple value-based hierarchies...?is that materialized views are not supported on top of value-based hierarchies in 11g. The reason is that it is not possible to write a reasonable SQL statement that aggregates a fact over a value-based hierarchy. Such a SQL statement is necessary if we want to create a rewritable MV on top of the cube.
    But I suspect this is not what you are really asking. If you are trying to set up OBIEE on top of the cube in 10g using the view generator, then you will probably want to use the "ET VIEWS" that are generated automatically in 11g. These are generated whether or not you enable materialized views on top of your cube. I am not aware of any issues with the generated value-based hierarchy view support in 11g. Members may be shared between value hierarchies and you will not need to generate or modify limit maps.

  • How can i change control values based on a read-in file?

    I understand that controls only have outputs and indicators only have inputs, but I'm looking for some help creating code that has the capabilities of both. Specifically and ideally, my front panel would allow the user to select an old spreadsheet file to read, and those values from the spreadsheet would be displayed. The user could then tweak those values to their liking, and then submit those tweaked values as a new file/overwrite the old/etc. The important part is the the indicating and controlling of the read in values.
    thanks
    Solved!
    Go to Solution.

    Using a local variable works well if I want to view and change a single value, but I want to view and change a few different values that are to be read in from a speadsheet. I have tried creating an array and then inserting numeric controls into the array, on the front panel. The code will run, but there is no output to the array control. I can't for the life of me pinpoint where the issue is.
    Is inserting multiple numeric controls into the array, not a good idea? Should I just create 3 separate numeric controls and local variables to get around this?

  • Value Based Dimension causing Aggrega                         tion problems

    I am new to building cubes in Oracle Olap, and am having trouble with a particular cube. (I hope I get all the terminology accurate enough to describe the problem I am having). Our organization structure is hierarchical. For example, org 0001is at the top of the "tree" and has 5 children: 1000, 2000, 3000, 40000, A000. Each of those 5 orgs have children that rollup to them. The problem is that the org "tree" is uneven. For example, Org 4000 has children that go down 4 more levels where the 3000 org only has children that go to level 3. We have about 1500 total orgs in the company. The dimension table we have shows the org_number and its Parent_org. Thus, I created an org dimension in AWM and then a value_based hierarchy. I can maintain and view the dimension in AWM and it all looks fine. I can then map the org dimension in the cube and maintain it (the cube that is). The problem is that the totals for my measures (actual costs) in the cube are way too high. Any advice as to what the problem is? I have verified that every org is in the table only once and that each org only rolls up to one parent org. I should mention that costs can be incurred by any org in the structure, no matter what level the org is at. Thanks for your help.
    Edited by: rybarrus on Jun 15, 2010 1:56 PM

    Thanks for your reply. That was a helpful suggestion. I found what seems to be the problem,but don't know why it is happening. When I look at a particular leg of the Org in the cube (in AWM) I see the following totals (indented to show parent child relationship):
    ORG--------------------Total
    1000...................602.42
    -------1030............557.48
    --------------1034.....557.48
    -------1060............ 44.94
    --------------1063..... 44.94
    When I Query the fact table I see the following totals:
    1000................... 0.00
    1030................... 159.05
    1034................... 557.48
    1060...................7,800.00
    1063................... 44.94
    To me, it looks like the total amount of the child is REPLACING the total of the parent. For example, the total in the cube for org 1060 should be 7,844.94 (7,800 + 44.94). Any reason why it doesn't sum correctly?
    Also, the total for org 1030 should be 716.53 (557.48 + 159.05).
    If you look back at my first post, I said that the overall total in the cube at the top level is way over the total in the table. That is still the case. This example that I have shown happens to be the opposite. The total I get when I query the fact table is greater than the total in the cube at this level. I hope that is not confusing.

  • OBIEE and Oracle OLAP Value Based Hierarchies

    Hi there...
    I have a value based dimension built on Oracle OLAP and want to map it on OBIEE Administration tool.
    I've been using the above link as reference:
    http://www.oracle.com/technology/obe/olap_biee/CreateBIEEMetadata.htm
    There's no option to import from Oracle Multi-dimensional Database. Either to import/configure the view created by OLAP as an Unballanced or Ragged Dimension.
    I also checked this example, but it uses ESSBASE as the multi-dimensional source....
    http://www.rittmanmead.com/2008/08/27/ragged-hierarchy-handling-in-obiee/
    How to map this Ragged Dimension created in OLAP workspace in OBIEE? Any suggestions or directions will be highly appreciated...
    Thanks in advance
    Marcos

    Mark and others,
    You can create OLAP_TABLE views with level columns on top of value-based hierarchies. BI Beans used to do that too behind the scenes in Discoverer Plus OLAP. If you trace the Discoverer session, where you are querying data from Value-based hierarchies, you will see that it also generates OLAP_TABLE views with level columns in it.
    So the question is how to do it. Internally, even for Value-based hierarchies Oracle OLAP keeps track of the "depth" of each value by using a structure called GID_DIMENSION (i.e., Grouping Dimension). Here is an example of a view on top of a value-based hierarchy (CFC_ACCT_GAPP) for RPT_ACCOUNT dimension. You have to know how "deep" your value-based hierarchy is.
    Similar kind of a thing is done by OLAP View Generator application, which I never use - since I always prefer to define my own OLAP_TABLE views.
    This kind of a view can then be used in the RPD of OBIEE.

  • Aggregation On Value Based Hierarchy

    Hi
    I am having a problem with aggregation on value based hierarchy
    Well I have a table which will serve as my fact and dimension table
    It is as follows
    ID     Name     MID     Salary
    0     All          
    1     A     0     10000
    2     B     1     9000
    3     C     1     9000
    4     D     1     9000
    5     E     2     8000
    6     F     2     8000
    I created a value based dimension named EMPLOYEE , with child as ID and parent as MID
    I created a cube EMP_SALARY with a measure salary mapped to the Salary column in Employee
    My expectation here is to see the total salary at every level including the salary at that level
    So let us take employee B as an example. He is the manager for employees E and F
    So what I would like to see at level B is sal of B + sal of E + Sal of F = 9000 + 8000 + 8000 = 25000
    But what I get from the cube is 9000. Now is the above possible ? If so please so provide me suggestions
    I can achieve the same by using the following sql query
    select e1.id,rpad('*',2*level,'*') || e1.name,e1.sal,
    select sum(e2.sal)
    from test_emp e2
    start WITH e2.id = e1.id
    CONNECT by PRIOR e2.id = e2.mid
    ) sum_sal
    from test_emp e1
    start with e1.mid is null
    CONNECT by prior e1.id = e1.mid;

    The same basic problem, along with a solution, was discussed in the following thread.

  • Preaggregation across value based hierarchy dimension in 11g

    Hi All,
    I have created a cube with 6 dimensions in olap 11g. One of those six dimensions has only one hierarchy which is value based hierarchy. I have chosen level based aggregation as I know at what levels exactly users are going to query. When I was going through the dimensions to choose levels to preaggregate I noticed there were no options available for my value based hierarchy dimension ( I could see "all" option for the same case in 10g) then I tried to look for definitions of underlying objects just to make sure it will preaggregate data across my value based hierarchy dimension.
    I found value set corresponding to my value based hierarchy dimension in <CUBE NAME>SOLVEAGGMAP object , which AWM uses to decide which dimension values to preaggregate but if I do rpr on that value set (rp r<CUBE NAME>SOLVE<DIMENSION NAME>_PVSET) it shows NA so my question is can I pre aggregate across value based hierarchy dimension in olap 11g?
    Olap Version: 11.2.0.1
    AWM version: 11.2.0.1
    Thanks

    Even if you know exactly which levels your users will query, percent based precompute (e.g. 30%) may still be faster in practice because queries are returned using 'sparse looping' instead of 'dense looping'. This was the single biggest performance advantage of 11g over 10g.
    But if you still want to use level based precompute, then you should look at the XML template for the cube (as saved by AWM, for example). In it you should find something called PrecomputeCondition. This defines the set of members that are precomputed. Here is an example I just created using the GLOBAL schema
    <PrecomputeCondition>
    <![CDATA[
      "TIME" LEVELS ("TIME"."MONTH", "TIME".CALENDAR_QUARTER, "TIME".CALENDAR_YEAR),
      CHANNEL LEVELS (CHANNEL.TOTAL_CHANNEL, CHANNEL.CHANNEL),
      CUSTOMER LEVELS (CUSTOMER.MARKET_SEGMENT, CUSTOMER.REGION, CUSTOMER.SHIP_TO),
      PRODUCT LEVELS (PRODUCT.CLASS, PRODUCT.FAMILY, PRODUCT.ITEM)]]>
    </PrecomputeCondition>The PrecomputeCondition is also visible through the USER_CUBES view.
    SELECT PRECOMPUTE_CONDITION
    FROM USER_CUBES
    WHERE CUBE_NAME = 'MY_CUBE';You can hand modify this condition in the XML to specify an alternative 'non level based' precompute condition for any dimension. For example, if you define an attribute named 'SHOULD_PRECOMPUTE' on your PRODUCT dimension that is 1 for members to be precomputed and 0 for all others, then you can change the condition as follows.
    <PrecomputeCondition>
    <![CDATA[
      "TIME" LEVELS ("TIME"."MONTH", "TIME".CALENDAR_QUARTER, "TIME".CALENDAR_YEAR),
      CHANNEL LEVELS (CHANNEL.TOTAL_CHANNEL, CHANNEL.CHANNEL),
      CUSTOMER LEVELS (CUSTOMER.MARKET_SEGMENT, CUSTOMER.REGION, CUSTOMER.SHIP_TO),
      PRODUCT WHERE PRODUCT.SHOULD_PRECOMPUTE = 1]]>
    </PrecomputeCondition>If you recreate the cube from the XML with this condition, then the PVSET valueset you discovered should contain all dimension members for which the attribute value is 1.   This gives you complete control over what is precomputed.   Note that AWM doesn't support this form of condition, so it won't show up if you go to the Precompute tab, but it is valid for the server.  The PL/SQL below will modify the PrecomputeCondition (for the cube named MYCUBE) without going through AWM.
    begin
      dbms_cube.import_xml(q'!

  • AWM 10.2.0.1 - I can not choosing Value Based hierarchy

    I have Oracle client 10.2.0.1 software with AWM 10.2.0.1 . I want to build a dimension with value-based hierarchy . In AWM I have hierarchy editor with the two radio buttons for choosing type of hierachy : Level Based hierarchy and Value Based hierarchy .

    Hi there,
    I really would not recommend that you work with the 10.2.0.1 version of AWM. This version is fairly old now and there have been a number of important bug fixes added to more recent releases.
    What version of the Oracle database are you running? And on what operating system?
    I suggest that you consult the following link and ensure that you are working with the versions of BOTH database and AWM that are recommended by Oracle:

  • Multiple Value Based hierarchies per MOLAP dimension

    Hi,
    a) Is it possible to have multiple value based heirarchies in a single MOLAP dimension in OWB and deployed to analytical workspace ?
    Are there any pitfalls, that we need to be aware of...
    b) Can we have a mix of Value and level based heirarchies per dimension ?

    Hi Chakri
    Yes, you can have multiple value based hierarchies and also a mix of value/level based.

  • Value based hierarchies and Period dimension should only contain  2  monthl

    Hi,
    Can anyone tell me what is value based hierarchies. And also can anyone let me know to filter the records in AWm because in Period dimension should only contain 2 monthly values (Oct. 2008 ( 200810) and Sep. 2008 ( 200809)) it is urgent.
    Thanks
    vel

    The following definition of a value hierarchy comes from the OLAP Developers guide
    "A hierarchy defined only by the parent-child relationships among dimension members. The dimension members at a particular distance from the base level do not form a meaningful group for analysis, so the levels are not named. For example, an employee dimension might have a parent-child relation that identifies each employee's supervisor. However, levels that group together first-, second-, and third-level supervisors and so forth may not be meaningful for analysis."
    Typically this means that the source table has two columns, VALUE and PARENT, where PARENT has a (logical) foreign key relationship to VALUE. An example may be EMPLOYEE, MANAGER, where MANAGERs are also EMPLOYEEs.
    The simplest way to restrict the values loaded into the AW is to define a SQL view over the source table with an appropriate WHERE condition. You then use AWM to map the dimension to your new view. E.g.
    CREATE OR REPLACE VIEW RESTRICTED_TIME AS
    SELECT *
    FROM TIME
    WHERE MONTH IN (200810, 200809)
