Roll out of parent child hierarchy

Hello
There is a parent-child hierarchy of the structure below :
A01    A11
A01    A21
A11    A111
A11    A112
A21    A121
A121 A1211
I need to convert it into hierarchy of the following structure
01              A01
0101          A11
0102          A12
010101      A111
010102      A112
010201      A121
01020101 A1211
Can somebody propose an algorithm or sample code
Thanks

Parent Child Hierarchy for Type 2

I have read the articles on Parent Child hierarchy setup in OBIEE 11g, however, most are based on what seems to be a current snapshot of the Employee-Manager relationship. Has anyone tried to build out a Parent-Child hierarchy/table off a Type 2 dimension. Being able to navigate what the hierarchy may have been on a specific date.
I would welcome any feedback, thanks.

Hi,
Thanks for the reply, I'm actually using snapshots. But even with the Type 2 Dim I don't think it will work.
When OBIEE generates the very first sql against the Parent-Child table the fact table is not included in the query. It seems to create 2 queries - one to find the top level parent (ancestor key is null) and then one to find all the leaf nodes.
It does not have any join to the fact table when it does this. So if you have multiple rows in the table (with date stamps) for a single row (person in this case) - it picks up both rows. Therefore, when you have a person who was, say, promoted to manager, and WAS a leaf node, and is now a manager, they show up in the leaf query and don't display in the hierarchy as a manager.
Once it has the leaf nodes and it joins to the fact table everything works (ie the surrogate key join).
I'm trying to figure out if there is any way to influence those initial queries against the parent-child table.
Hopefully that made sense.
Thanks,
Tori

Parent Child Hierarchy Issue in OBIEE 11g

Hi All,
I am in OBIEE 11G v6. I have a sales fact table where the grain is one sale. So I have one row for every sale done.
Now I have a ragged employee hierarchy like this with David at the root node.
David >>Richard>>Sean
David >>James
Also, I have a role dimension which gives me what role each employee has performed on a sale. Only one employee can be associated with one sale. This is the way Roles have been asssigned
David = Manager
Richard = Off1
Sean = Off2
James = Off2
Both Sean and James can have same Roles. Now I have created a parent child hierarchy for my employee dimension and the closure table. Defined the member key, ancestor key relationship in the parent child setting etc.
Now in the report when I pull the parent child hierarchy and the sales_amount in the report, it comes out perfect with all the ragged hierarchy resolved. But the issue comes when I try to limit the report on Role = Off2. It gives me an error saying " The layout of this view combined with the data, selection , drills resulted in no data. Undo drill and view prompt values". Basically what i want is to be able to select any role type and then my hierarchy should be adjusted to show me that data. Like when I select Off2, I want to see David at the Top level and Sean and James under him because they are both Off 2 and David is their manager.
Is that possbile? Also, am I getting this error because when I select Off2 though it gets Sean and James but since David is not Off2, I don't get the data?
I hope I was able to explain the issue, any help on this would be greatly appreciated.
Thanks
Ronny

So basically this means that if I build a parent child hierarchy on table A having the stucture like
--David (Manager)
-----James (Off1)
--------Bill (Off2)
and in my sales fact table for let's say today, I have only rows for Bill (Off2) because he is the only officer who did the sales today. Now when I will join my fact table to parent child hierarchy table A I will NOT get any data ? because there is no James who is the parent of Bill. So obiee need to have parent pulled off in the data (ANCESTOR) to be able to roll up the child.(IS_LEAF = 1)
I testes this and if my data only contains only rows for Bill (or I limit on ROLE = Off2) then it won't show the hierarchy. The query which OBIEE fires is to look for either ANCESTOR_KEY = NULL OR (DISTANCE = 1 AND ANCESTOR KEY IN (Bill). Therefore it doesn't I am wondering then what is the use of builiding the parent child hierarchy when we need to pull in all the ancestors (like in this case James for bill and David for james) because in real scenarios there can be cases wherein we would want to filter the data based on other dimensions to which the parent child hierarchy joins ?

Parent-Child Hierarchy Show No Data

Hi:
OBIEE 11.1.1.6.5
I created a parent-child hierarchy following multiple examples in books and on the web. I can pull the presentation hierarchy--by itself--into a view and drill up and down. But when I add a measurement from the fact table, I receive a no data found error. I copied the SQL into SQL*Developer and ran it, and it too returned no data. I've tried to read and debug the query in SQL*Developer, but I don't understand what it is doing.
The dimension table I am using for the parent-child hierarchy has a cost_Center_id and parent_cost_center_id. I used the Parent-Child dimension wizard to create and populate the new hierarchy table.
I can create a view by using the cost_center item and a fact table measurement without the presentation hierarchy, so it has something to do with the presentation hierarchy.
I've been at this for a few days now, and I've run out of ideas. Can anyone suggest what I may have done wrong?
Thanks.

check if there is data in the fact table.. Next check also if the join condition between the dimension and fact is valid.

Parent Child Hierarchy in OBIEE 11G

Hi All,
I am working on the parent child hierarchy in OBIEE 11g Source ESSBASE ..followed some of the blogs.
http://www.rittmanmead.com/2010/07/obiee-11gr1-enhancements-to-essbase-support/
I followed the following steps.
1.Imported the Cubes from ESSBASE.
2.Selected Accounts Hirearchy and changed the Hierarchy type to Value.
3.Dragged the subject area to BMM and to Presentation.
4.Now when i checked the Account Hierarchy from in the dashboard its not drilling down.
If i change the Hierarchy type to Unbalanced ...then the Account hiearchy is working fine.
Is there is any settings or process i have to follow..inorder to implement the Value based Hierarchy in OBIEE 11G source ESSBASE.
Thanks

Parent Child Hierarchy Issue

Guys,
I have a parent-child hierarchy and users would select a randomn level from the prompt (Hierarchical column used in the prompt). So for the level selected I need to capture all the leaves and put a top n function on them.. Any ideas??
Things that i have tried are using Selection steps with hierarchical columns.
Step 1: Start with all Memebers
New step: Step 2 is Selected Members based on hierarchy relation Ship (Keep only members of leaves of hierarchy)
But the problem is I am not able to override the Step -2 with dashboard prompt. I was able to do only fior STEP -1
So any ideas??
If i can atleast capture all the leaves of selecte level from the prompt that would solve my problem to a large extent?/ Thought abt Hierarchical Navigation Functions but didnt succeed?? Any suggestions really appreciated
Thanks..
Prash
Edited by: Prash11 on Aug 6, 2012 11:14 AM

I have got lot of hierarchies which are atleast 20 levels deep. So its not really feasible for me to create multiple views for multiple levels.
I tried to use hierarchical column functions and it works but not able to override the values from prompts in the selection steps. So still trying few things
Step 1: Start with All members (over ride with prompt checked)
Step 2: Select a level with in the hierarchy and Keep only leaves of the selected level
Step 3: Apply Condition do a TOP 10 and keep only that result set.
This works fine with out any issues from an ad-hoc stand point. Only problem there is no way for me to over ride the dashboard prompt value in Step - 2 as it expects me to select a value from the hierarchy. Any alternativeS?

Except function with parent child hierarchy using mdx query

HI,
I need to remove some items using mdx query in parent child hierarchy.
I tried with below query,it is not removeing ,could you please help me.
SELECT
{[Measures].[Amount]} ON
COLUMNS
NonEmpty([Account].[Accounts].[Account Level 01],[Measures].[Amount])
ON ROWS
FROM (SELECT
-Descendants({[Account].[Accounts].&[47]},,Leaves)
} ON COLUMNS
FROM [Adventure Works])
indu

Hi Indu,
Why do you remove some itmes using
Descendants function? Generally, we use FILTER function to achieve the requirement.
WITH SET [CustomAccounts] AS
FILTER ([Account].[Accounts].[Account Level 01].Members , [Account].[Accounts].CurrentMember.Name<>'Net Income')
SELECT {[Measures].[Internet Sales Amount]} ON 0
[CustomAccounts] ON 1
FROM [Adventure Works]
WITH SET [CustomAccounts] AS
FILTER ([Account].[Accounts].[Account Level 01].Members , [Account].[Accounts].CurrentMember.Name='Net Income')
SET [RemainingAccount] AS
[Account].[Accounts].[Account Level 01]- [CustomAccounts]
SELECT {[Measures].[Reseller Sales Amount]} ON 0
[RemainingAccount] ON 1
FROM [Adventure Works]
Results.

Parent Child Hierarchy causes numbers to be different

Hello,
We have a parent child hierarchy in our chart of account dimensions. When the hierarchy is included in an analysis, the numbers are correct. If the hierarchy is not included in the analysis and a column from the dimension with the hierarchy is included, the numbers are very different. They are overstated by a large amount.
For Example, I have two analysis:
-In the first analysis the hierarchy is included and the grand total is 2,383,080,784.
-The second analysis has simply excluded the hierarchy from the analysis and the total shoots all the way up to 6,901,729,527.
I have screen shots but don't know how to include them in this kind of a post.
Has anybody else seen such behavior? This seems like it would be a big deal so either we are doing something wrong or this is a bug that needs fixed.
We are on 11.1.1.6
Thanks in advance,
Brian

Parent-child hierarchy - Values not showing

Hi all,
I've created an Account Dimension based on the account dimension in Adventure Works Cube.
What I need to know is how to show account's values when I drag the Account Number to the grid. When I drag the Accounts chart to the grid, all the accounts are shown and their values are shown as well, but when I drag only the Account Number to the grid
only the leaves' accounts are shown. Any ideas?
Rafael Fontana

Hi Rafael,
According to your description, you created a Parent-child hierarchy using account dimension in Adventure Works Cube, and now you want to query out the members on that dimension, right? If in this case, here is a blog which give out some sample query about
how to query dimension members, please see:
Querying dimension members in MDX
If I have anything misunderstood, please point it out and elaborate your issue, so that we can make further analysis.

Calculate measure in parent child hierarchy

Halo everyone
I have a requirement about parent child hierarchy namely:
1. see the following picture as a sample.
the situation I got here is every employee has its own measure (Sales Amount). when it rolls up to 'Employee1' so the Sales will calculate all measure (Employee1 and all the descendents) but when it drill down, 'Employee1' will ONLY show its own 'measure' (it does'nt calculate from its descendents).
Any suggestion, Any idea, Any sharing, Any inspiration would be appreciated. thanks alot.

Hi Vin,
We can use Descendants() funcion, which returns the set of descendants of a member at a specified level or distance, optionally including or excluding descendants in other levels.

Problem creating standard ECC Parent-Child Hierarchy in HANA

Hi all -
I've been trying to get a hierarchy to work on the front end of a stand alone HANA system using profit center hierarchy data from SETLEAF / SETNODE tables from ECC. Here is how my test hierarchy looks:
Following another post I found around here, I created an attribute view and filtered SETNAME to 'TST_HANA'.
The resulting data when connected to my attribute view caused an error that there was no root node, so I manually inserted the last row shown here (where PCA_PARENT = SETNAME and PCA_CHILD = SUBSETNAME):
Finally, I created my parent-child hierarchy in the attribute view and connected that view to my data foundation in the analytic view via left-outer join between Profit Center and VALFROM. However, when I go to connect to my view via MDX in excel, I get the following message:
"Hierarchy create error: Multiple parents not allowed for hierarchy node TST_ND1" Clearly from the data, there aren't multiple parents for TST_ND1. It's already a pain that to use a standard hierarchy I have to manually insert a root node, but that doesn't even seem to fix the problem.
Can anyone suggest how to fix this to get a standard profit center hierarchy working?
Thank you!
AZ

Hi,
According to me, Hierarchy level will work fine in ms excel for all analytical, calculation view using MDX Provider..
Do you have any composite primary key or composite foreign key in the tables....
r u getting correct level hierarchy output in Hana studio... plz check with all types of permutation possible.if u r getting correct output in analytical view w.r.t hana but fails to get in Ms excel..
please create Calculation view of that.. & then check the output in ms-excel..
Thanks,

Tabular - Parent/Child hierarchy - hide duplicated rows problem

Hi All, in all the Tabular parent-child hierarchy examples I could find a measure is created to calculate current node depth. Later that measure [CurrentNodeDepth] is compared with aggregated node depth using MAX/MIN functions. The current node depth measure
uses ISFILTERED DAX functions like
CurrentNodeDepth := IF (ISFILTERED ('Hierarchy'[Level3]), 3,IF (ISFILTERED ('Hierarchy'[Level2]), 2, IF (ISFILTERED ('Hierarchy'[Level1]), 1)))
All works ok until you start filtering the hierarchy - that might happen with very big hierarchies - showing only part of hierarchy to speed up calculations. Once you set a filter there, [CurrentNodeDepth] measure gives wrong output and whole parent-child hierarchy
doesn't work as it should.

Can you provide more info on this, how have you modeled the hierarchy with the fact table, are you rolling up the measures for the child to the parent level (modeling as measures) or each employee is showing its own revenue only (modeled as attribute)? If it is modeled as measures where you join the employee table to the closure table and then that to fact table then are you applying any filters in your report ? If you are applying filters in your report and somehow only parent is filtered (and not its children) then you won't be able to drill down, though you will see the + sign against it.

Essbase Studio (parent-child hierarchy + attributes)

There is a problem with the parent-child hierarchy and attributes (for example, structural units of the enterprise).
Composition data (source - table in Oracle):
id (ID of the structural unit - a surrogate key, it is PK)
idParent (ID of the parent structural unit)
code (code of the structural unit - the natural key)
name (the name of the structural unit)
type (type of structural unit)
address (address structural unit)
In this case, parent-child relationship is defined fields idParent -> id, all the rest - should serve as attributes for the various disclosures in the reports.
In all the examples that are found in the network, parent-child built without creating attributes, and it really works. But how "to enrich" the attributes of a hierarchy - and sample solutions are not found.
Most requested help: link, advice, examples from life, either by pointing out that "so definitely not!".

Dear guru of essbase,
I am quite sure that this problem can still be solved by Essbase Studio.
I can not believe that the Studio developers could not include this feature. It is very important to resolve this issue it is through this component, help please both. Thanks

No data for Parent-child hierarchy column in Pivot table view

Hi all,
I used OBIEE 11.1.1.6.2 Version.
I drag one Parent-child hierarchy column and one measure and show result with a pivot table view.
But when I click "+" icon to show detail level data,
It messaged that: "*the layout of this view combined with the data,selections,drills,or prompt values chosen resulted in no data*."
But it can show every-level data when I used table view.
It was so strange..
Did anybody meet this before?
Thanks in advance.
regards,
Anne

Hi,
Yes, I have the same problem with pivot table for hierarchy dimension.
If you use a normal table (not pivot) it seem to work. Unfortunatley with restrictions as normal table view have.
Same problem still exist in 11.1.1.6.5
I have logged a SR to Oracle about this.

How to update a parent child hierarchy in OBIEE

Hello All
Quick question about updating parent child hierarchy in OBIEE.
As we know, OBIEE 11G allows us to create value based hierarchy by generating table creation script and insert script. In the typical example of employee dimension, the parent child relationship table will be created with the following 4 attributes:
MEMBER_KEY, ANCESTOR_KEY, DISTANCE, IS_LEAF
So, what if later in the years some of the employees got promoted, retired or transferred? The value based hierarchy is going to change because person 1 reports to manager 2 now instead of 1. Obviously, the records in employee dimension is going to be updated. When that happens, how to update the parent child relation table with the same information? Do we have to rerun the insert script? How do we keep the history of employee changes and hierarchy changes?
Please advice
Thank you

I guess it will update when the structure changes,Let see the response from other gurus.
Thanks,
