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 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..

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?

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 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

OBIEE 11g Parent Child hierarchy

Hi,
I'm trying to setup a parent-child hierarchy dimension. I have setup a new hierarchy dimension using numeric keys but want to display another field in the hierarchical column on a report e.g. employee fullname & not the member_key based on a numeric value. Can this be done & how do you do it? All the examples I have seen use varchar2 type columns as the keys to do this.
Thanks in advance, Phil
My Setup
=============
Dimension - logical level
===============
member key = employee_id
parent-child table source
===============
member key = employee_id
parent key = supervisor_id
relationship distance = levels_removed
leaf node identifier = isleaf
Employee logical folder
==============
employee_id ( number)- primary key
full_name (varchar2) - unique key
supervisor_id ( number)
Closure table
=========
employee_id ( number)
supervisor_id ( number)
level ( number)
isleaf ( number)

Thanks for the link Suresh but the aggregations are working correctly.
My problem is only at the display level. I need to create a dashboard that displays the complete hierarchy.
So for example if I have this hierarchy:
- Steven King
- Adam Frip
Alexis Bull
Anthony Cabrio
Alberto Erraruriz
Den Raphaely
I want the dashboard to display immediately that complete hierarchy. If someone adds a member to the hierarchy in the database, the dashboard should display this new member without having to manually modify the dashboard.
- Steven King
- Adam Frip
Alexis Bull
Anthony Cabrio
- Alberto Erraruriz
Mozhe Atkinson
Den Raphaely
Also, if I just manually open the hierarchy and save the dashboard, if "Steven King" is replaced by "Shanta Vollman", the dashboard doesn't like it and returns a result looking like:
- Adam Frip
Alexis Bull
Anthony Cabrio
- Alberto Erraruriz
Mozhe Atkinson
Den Raphaely
+ Shanta Vollman
So I'm looking for some option that will tell OBIEE to open the hierarchy without having to specify "Drill down on member "Steven King"", "Drill down on member "Adam Frip"...
I hope I'm explaining correctly...

OBIEE 11g: Skip a level in a parent-child hierarchy

Hi everyone,
I've got a parent child hierarchy setup. It's basically Total Company -> Continent -> Country. It's working fine.
For one particular report, the end user would like to bypass continent for just Asia. The rest of the countries should go through their continent first.
For example,
Total Company -> Europe -> Germany
Total Company -> North America -> Canada
Total Company -> Japan
Total Company -> Korea
We do not want to change the hierarchy as it is a corporate standard and eventually we want the grouping there. Just for a single report, we want to bypass.
Is there anyway to do this?
I tried to remove the "Asia" node while building the report, but it also removes the children. So then I tried adding back in the children and they weren't part of the hierarchy. They were off in their own duplicate hierarchy.
Hopefully this is possible.

Hi,
you mean for example you want to create a level 3 WBS under a level 1 WBS?
is that what you mean by skip a level?
that is not possible, i cant even think of a scenerio why you might want to do that. (but i'm curious why you asked)
it isnt even logically feasible. you can create WBS levels only one at a time.
Good day.

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,

Sub Total value is empty in parent child hierarchy pivot table

Hi All,
I am using obiee 11.1.1.6.2 in Test environment. Is it a known issue/bug for 11.1.1.6.2 to show empty/blank values for sub total when using parent child hierarchy pivot table. The sub total for parent value is showing but sub total for child value is coming blank. However, in 11.1.1.5.0, we do not have any issue with this.
Is it a known bug in obiee 11.1.1.6.2?
Thanks,
Sushil

Yes it is a known bug...
Thanks.

Parent child hierarchy and measure using lookup

Parent-Child hierarchy based on two-column key

Hello
Is it possible to create a parent-child hierarchy, if the primary key of the table consists of two columns?
My table looks like:
TRACE_ID | DIAG_ID | SUPER_DIAG_ID
with TRACE_ID and DIAG_ID as PK.
If I define only DIAG_ID as PK, I can add a logical dimension (PC-hierarchy) without problems.
However when I also add TRACE_ID to my PK, I cannot select a member key in the new logical dimension window and therefore not create a logical dimension.
Is this a limitation of OBIEE and I have to merge the two colums (which would be rather bad, as there are FK relations to DIAG_ID) or is there a solution?
Regards
Matthias

Dear Gowtham ,
I am very well aware of the level based hierarchy available in BO .
The issue that i have raised is all about the Parent Child Hierarchy which creates the recursive query.
I.e Every Parent has a child and that child can be parent of some other . (See the original example for more illustration)

No Results after build a Parent-Child Hierarchy in OBIEE11G

Hi All:
Here's an problem. I followed the "http://sandybi.wordpress.com/2010/08/17/hierarchies-in-obiee-11g-part-1/" this article step by step to create a parent-child hierarchy in admin tool in OBIEE11G.
But after check in and try to retrieve the hierarchy data in Answer. There's always displays "No Results."
Is there any suggestions for this ? Really urgent and thanks for your help.
Best regards
Sunny

@Aketi
It is One way that We derive
"sys_connect_by_path(RowIDToChar(RowID),'.') as
RowIDList"
Then
We use Left Join Using
"instr(RowIDList,RowIDToChar(RowID))".sorry, didn't catch what you mean.

Parent Child hierarchy Scenario

Hi friends,
Im just working on the parent child hierarchy using the following link with the sample data.
http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/bi/bi11115/biadmin11g_02/biadmin11g.htm_
I tried to implement the same hierarchy using my local data instead of referring to the sample data.
I have a below query which returns the employee with manager along with the employee position
select distinct papf.person_id, papf.full_name "Employee Name", supf.person_id "Manager Id", supf.full_name "Manager Name", pj.name "Position Name"
from per_all_people_f papf, per_all_assignments_f paaf, per_all_people_f supf, per_jobs pj
where papf.person_id = paaf.person_id and supf.person_id = paaf.supervisor_id and paaf.job_id = pj.job_id
and trunc(sysdate) between paaf.effective_start_date and paaf.effective_end_date and
trunc(sysdate) between papf.effective_start_date and papf.effective_end_date
Im looking forward to implement the same result in my BI with a parent-child hierarchy.
Since i have imported three tables to my physical layer
per_all_people_f------------Dimension
per_all_assignments_f-----Fact
per_jobs---------------------DimensionFor creating parent-child in BI, we need to have a separate Parent child table which consist of four columns like ancestorkey, memberkey, distance, leaf.
From the above column i can understand the meaning like
For Ancestorkey-->Managerid
Memberkey------->Employeeid
But i couldnt get with the meaning for distance column as the meaning suggest like a distance b/w the two and leaf column as the meaning suggest like a leaf member. which leaf member does it refer.
I also referred the below link then too couldnt get the meaning for it
http://www.rittmanmead.com/2010/08/oracle-bi-ee-11g-parent-child-hierarchies-differing-aggregations/+
How i can form the parent child table for the BI from my above three tables of HRMS.

Parent-child hierarchy and fragmentation content

Hello,
I've tried to build simple model with OBIEE 11 using Oracle 11r2 as a data source. BMM has fragmentation content for fact table and few dimensions with different hierarchy types. It works fine with all hierarchy types except for parent child.
When I build an answer with parent child hierarchy it terminates with error "Target data source does not support the operation".
Does OBIEE 11 not support parent child with fragmentation content? Or am I missing something?
Greetings
Marcin

I'm seeing the same issue. I've created a parent-child hierarchy along with two normal level-based hierarchies (one "normal", one skipped-level). The two level-based hierarchies work just fine in Answers. I can include them in the criteria, and data is displayed with the correct drilldowns.
If I include the parent-child hierarchy, I get the same results as noted in the original post: "The layout of this view combined with the data, selections, or drills, or prompt values chosen, resulted in no data." I'm trying to look at the table view, with no filters.
Interestingly, I can explicitly include that dimension's Parent column and Member column in the criteria, and data is displayed just fine.
Here is the XML for the set of criteria that includes the separate Parent and Member columns (the one that works):
