Dimension hierarchy creation

Does exist best practices for creation of dimension hierarchy based on table like
CAT_ID,PARENT_CAT_ID,CATEGORY_NAME where hierarchy tree might have different number of levels:
level1-level2
root -- level1-level2-level3
level1

Thaks for your answer, I already read those articles. Actually question was about creating in OBI of hierarchy which has different number of child levels like this:
Organization - Division1-> Division1.2->Division1.3
- Division2-> Division2.1->Division2.2->Division2.3
Number of parent divisions under Organization is unlimited (Siebel model) and in table on which hierarchy is based not denormalized.

A Question Related to Dimension Hierarchy

Hi All,
While going through some hierarchies, i found that some columns were associated with the levels in hierarchy but these columns were not part of level keys.
I want to know that what is difference between the result when columns that are not level keys are associated with a logical level and when such columns are not associated with a logical level ?
Does such columns affect the result when selected in BI Answer?
For exp -
Suppose i have below time dimension hierarchy -
Time
->Grand Total Level 0
---> Year Level1
Year (Level Key)
Year Start Date
Year End Date
---> QuarterLevel2
Quarter(Level Key)
Quarter Start Date
Quarter End Date
---> MonthLevel3
Month(Level Key)
Month Start Date
Month End Date
---> Day Level4
Day (Level Key)
Day Start Date
Day End Date
These start date/end date columns are not part of level keys.
The same thing i have observed in other hierarchies too.
I want to know that what would happen, if these columns are not present at these levels?
So When should we associate columns those are not part of level key to levels and when we should not associate ?
Thanks,
Ashish

Hi ,
The non key columns used in each of the levels help in faster retireval for that aggregate level .
If you look closely at these columns you will find these to be unique ,now having said that another point is that these levels are also used for aggreagation
as we all know.
For ex at the month level the key identifies all the unique moths but if data has to be shown for one particualr month then with the start momth date and end month date the retrieval would be still better :)

Dimension Hierarchy

We are in the process of creating a dimension hierarchy. We see multiple options here
There is Logical Level. Each logical level can have multiple keys. Each key (*Logical Level Keys* ) can have multiple multiple columns. Each column has a check box. The Logical Level Key dialog shows Use for drill down option.
What is the significance of
keys
Logical Level Keys
The check boxes

Any thoughts on this please ?

Total levels on pivot with dimension hierarchy column incorrect

Hi,
I have a pivot table based on a single subject area, based on an Essbase cube.
The problem I have is that some of the totals against the collapsed dimension hierarchy column are incorrect, it is as if they remember the pre-updated state, even though I have bounced the services and turned all caching off.
When I expand the node then the totals appear correctly, but when reverted to the collapsed state it shows nothing again.
I have turned off caching via EM.
I have tried all flavours of totals, default, server complex aggregate et al with the same result for all.
I have double checked the results at source with an identical query in SmartView and the upper level dimension total is populated in its own right, as well as its children carrying totals which do not sum back to zero.
Any suggestions please??
thanks,
Robert.

Can you validate the query hitting to the database and compare the results?

Dashboard prompt on a Dimension Hierarchy in Obiee 11g

Hi All,
I have created a hierarchy (parent-child) on a dimension 'A'. I am able to create a dashboard prompt for the dimension hierarchy. However I am not sure how to create a report that is to be filtered on this dashboard prompt. I tried using the attribute name that the hierarchy uses but that does not work. Can some one please let me know how i can filter a report by a hierarchy dimension prompt.
Thanks,
Nikita

Hi Nikita,
For your requirement, you need to go for Selection steps pane in the analysis(report). Click on steps link and then add the hierarchy column that you want to use and expand the hierarchy to the lowest level. Now select all these and all the attributes will now appear in the other side.
If you dont expand the hierarchy to the lowest level, then only the highest level values will appear in your selection at prompt.
Also make sure to check the 'override' checkbox in the bottom, this helps in filtering the values.
Hope this answers your question.
Cheers,
Obul

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.
Thanks
Ankita
Edited by: 848789 on Sep 28, 2011 8:40 PM

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.
Thanks,
Satya

Report totals with dimension hierarchy column on pivot table incorrect

Hi,
I have a pivot table based report that has one dimension column, a dimension hierarchy column and various measures.
The row totals do not match, detail to total, and I have tried both complex server based aggregate and report based aggregation, but neither are giving me the correct answer.
I have also tried adding the column that is the same as the top level as the hierarchy, but hidden, but this does not help.
I have also tried adding the lowest level of detail column, but hidden, but this does not give me the solution I need as all of the figures then appear at detail not aggregated level.
Any ideas please?
thanks,
Robert.

Oracle Business Intelligence Dimension hierarchy question

Hi,
I am prasanna.I have a problem while display the data from dimension hierarchy.I have created a time dimension hierarchy.I can drill down upto week number but i m unable to display the time_id(this is the last level of the hierarchy).When i check the properties of the time_id,the HIDE check is checked.Even if i uncheck the checkbox also i m unable to display that column.How to change properties of the column manually.I can find the column at the criteria but not at results tab.How can i display the column.
Thanks ,
prasanna

HI Prasanna,
what is the least granularity for your time dimension? is at week level or day level. verify the dim hier configuration in rpd. if you define time_id as level key you dont get that column in answers results while drilldown. you may create another logical column and drag it to week level as an attribute then you will get it. and why do you need time id in answers. generally we dont use id's for reporting.
try again after above configuration and you will be all set.
Thanks
Jay.

Changing the dimension hierarchy level keys in RPD online mode caused issue

Hi,
We tried to correct the dimension hierarchy level keys and remove prefered drill path settings in the business model layer in RPD in online mode. However this caused all the reports and dashboards based off of this subject area to show incorrect, and/or restricted data. The physical query generated by the answers requests were also incorrect.
Even restarting the server and presentation services could not resolve the issue. Can someone please help us to understand what could have caused this issue?
Thanks in advance

Hi,
I am not sure why the existing reports throw an error when I change the RPD dimension hierarchy level keys. Does anyone know how I resolve this issue.
This is urgent. Any help will be most appreciated.
Thanks in advance.

Star Schema Dimension Hierarchy Changes Over Time

Say you have a dimension hierarchy with the level Department that has a child level Division. The Sales Division belonged to the Financials Department up until July 9th, 2011, after which it was moved to the Marketing Department. How can you make it so that both Sales Divisions are interpreted as the same Division, rather than two different Divisions as BI Answers does by default?

I don't think SCD1 would work as BI Answers essentially splits things via both keys and description fields, resulting in odd behavior such as this:
Time
Division
# Employees
All Time
Sales
16
22
Regarding SCD2:
So is there something I need to do on the repository so that BI Answers knows to switch between the two versions of the same Division at that particular time, such that I can make an Analysis such as this:
Month
Division
# Employees
% Change
May
Sales
15
-6%
June
Sales
15
0%
July
Sales
14
-7%
August
Sales
22
+57%
Instead of this:
Month
Division
# Employees
% Change
May
Sales
15
-10%
June
Sales
15
0%
July
Sales
2
14
-87%
0%
August
Sales
22
+57%

View dimension hierarchy using the filter property of data form

Hi,
I created a data form where I want to show the dimension hierarchy. But when I am filtering the form using attribute dimension then the hierarchy is not being shown in the form.Is their any way so that I can use the filter property also and make the dimension hierarchy visible in the data form?
Thanks.

Hi Endy,
Thanks for your reply. I have used the "equal" function as to set that specific attribute as I am choosing the descendants function against the attribute dimension,it's showing error.Hi,
What's the error ? You have to use a function, otherwise it will only display the member you picked.
Actually in our dimension structure we have a 3 generation hierarchy and the attribute is only associated with the 3rd generation member. So we want to display the 3rd generation having the specific attribute "xx" wit the entire hierarchical structure in our data form.
Can you please tell me if I have missed anything?
Thanks.If you want to display the attribute value in the form, edit the form, go to the "Layout" tab, and click on your row. On the right side of the screen, you have a section called Display Properties. Check the box called Enable custom attributes, then check your attribute name. Save the form and you will have the attribute value displayed at the right of the member name.
