N Level Parent child hierachy (BO)

Hi Tammy ,
Thanks a lot for the valuable information that you have provided .
Can you please let me know whether we can handle N level hierarchy in 4.0 Universe in Member Ancester format . e.g
Member_key       Ancenster_Key
1                                  3
2                                 3
3                                 5
4                                 5
5                                 6
6
When I drill in my report from 5 it will go to 3 and 4 . and when i drill from 3 in same report it will go to 1,2 .
Can we have have recursive query generatin with help of the hierachy ?
regards ,
Jeevan

Thanks Dpka, I did exactly that, there is a small issue. Let's say my hierarchy is (I have just dded one more level under David). So James and Terry reports to Thomas and Thomans reports to David.
--David(165)
----Thomas(65)
------James(25)
------Terry(30)
David is the top level and Thomans the next level. Now when I click on David, it takes me to the target report and shows me the revenue as expected but when I click on either Thomas, James or Terry, it doesn't take me to the target report. At the bottom left it shows me an error. This is what the error is
Message: 'getLevelInfo(...)' is null or not an object
Line: 1
Char: 11142
Code: 0
URI: http://wmdwm100a.midlandls.int:7001/analytics/res/b_mozilla/answers/selectionsmodel.js
So It is working only for the top level managers whose doesn't have any anscestor. Any ideas why is tha so?
Thanks,

Multi level parent child relationship and datacontrol

I have an existing application with multi-level parent child tables. For example three of the tables in the applications are related as Table 1 ( parent of Table 2) ---> Table 2 ( parent of Table 3 ) --> Table 3. When i create ADF Business components using these tables i see only the nesting between the parent and its immediate child tables. How can i create a nested data control for Table 3 to Table 2 to Table 1?. We have a usecase where we need to access data from the child table to parent to parent in the reverse order. Currently there is no direct relationship defined between Table 1 and Table 3.
Any thoughts?
thanks

Hi,
double click the Application Module to open the AM editor. Select the data Model category. On the right hand side you see what is selected for use in an application, on the left hand side is what you have available as View Object. To create T1-->T2-->T3, you
- Select T1 and move it to the right
- Select T2 under T1 on the left and move it to the right under T1
- Select T3 under T2 on the left and move it under T2 in T1 on the right

Parent Child Hierachy Revenue Rollup Issue

Hi All,
I have modeled my parent child hiearchy in such a way that revenue for each parent is equal to sum of his revenue and all his descendents. So If this my table
Empname|Revenue
David|100
James|25
Terry|30
this is what my hierachy shows
--David(155)
---James(25)
---Terry(30)
Now this is working perfectly fine and this is how users want it to be. To roll up the revenue for all the descendents uptil the top level.
The issue is, users also want to see what revenue David contributed. Because, as per the above example, when they try to add 25(James) + 30(Terry), it comes to 55 and the revenue contributed by David (100) becomes implicit and David straightaway shows 155. So they want to have a small pop up or any other column in the report which bifurcates David's revenue with others just to add more sense to David's revenue of 155.
Is there any workaround which could be done in the same report or do I have to create a separate detail report ?
Thanks,
Ronny

N-Level Parent-Child Aggregation

Hi,
We have an account table and a transaction table, the account schema is
Account ID
Account Name
Parent Account ID
The account hierarchy level is N-Level. The business user can add account/sub account.
Account ID | Account Name | Parent ID
1 | FX Gain (Loss) | null
2 | Asia FX Gain (Loss) | 1
3 | China FX Gain/Loss | 2
4 |Japan FX Gain/Loss | 2
5 | Promote Fee | null
In this table, the hierarchy is
FX Gain (Loss)
|- Asia FX Gain (Loss)
|- China FX Gain/Loss
- Japan FX Gain/Loss
Promote Fee
Promote Fee & FX Gain (Loss) are the root. And Promote Fee doesn't have any child or grant-child.
======================
Transaction Table schema is
Transaction ID
Account ID
Amount
Date
Sample data
Transaction ID
Account ID
Amount
Date
1 | 3 | 10.0 | 12/1/2009
2 | 3 | 20.0 | 12/2/2009
3 | 4 | 30.0 | 12/1/2009
4 | 5 | 40.0 | 12/1/2009
We want to use BusinessObjects to build account drill-down reports with aggregated transaction amount.
For example, the report likes this
Account Name | Amount
FX Gain (Loss) | 60
Promote Fee | 40
User can drilldown FX Gain (Loss):
Account Name | Amount
Asia FX Gain (Loss) | 60
Then, drilldown Asia FX Gain (Loss):
Account Name | Amount
China FX Gain/Loss | 30
Japan FX Gain/Loss | 30
How to design the universe and the report? Any sample?
Your help would be highly appreciated.

Parent Child Hierachy Drilldown (without including the hierachy column)

Hi
I have a hierarchy with categories/subcategories, which goes into a table like this:
Category Name Amount
Top cat1 23
Top cat2 5
I want to use the Category Name column to drill down to the sub categories, so that if I click "Top cat1", the table will look like this:
Category Name Amount
Sub cat1-1 23
Sop cat1-2 5
The "Drilldown" option for the actionlink in column interactions doesn't do anything for this hierarchy, and by trial and error we worked out that it only seem to work with level-based hierachies (but in a warped way. It adds an additional column for every level!).
Trying to use an actionlink doesn't work too, since there's no good way of passing the clicked category ID to set as the parent ID of the next page.
Using a GoLink URL did work, BUT navigating to a completely new page doesn't fit our requirements.
Is there a way for us to do this? Thanks!

Parent/Child Master Data Type

I recently created a new master data type in my model, which included one attribute with the 'parent' check box checked - to signify that it was to be used as the parent.
Upon activating the master data type - the system auto generated several other attributes within the master data type. My question is, what is the purpose of these additional attributes and how are they to be used?
Before Activation:
Attribute

Hey JJ,
The purpose of these attributes is for parent-child hierachy relationship.
In addition to above mentioned attributes, you should also notice (via HANA studio), that another Planning object gets generated automatically. The new planning object should be the name of your parent-child object plus "_ANC" prefix at the end.
If you take a look at this planning object, you will notice that the object contains all the generated attributes (your attriubute plus "A" prefix at the end) in the definition.
Once you load data into your parent-child hiearchy object the "_ANC" object will automatically get populated with parent-child node relationship.
"A-prefix" attriubutes essentially represents the attributes of ancestor in this case.
In addition, in order to do Ancestor rolllup in your calculation you will also need to create an ancestor planning level which contains all the attriubutes of your base planning level as well as these "A-Prefix" attributes.
Please take a look at the document we created for "How to configure Parent-Child Hiearchy" from the share link
It has more detailed information.
Thanks.
Daniel.

Generation v/s Parent/Child

Hi, i try build a dimension with generation and parent/child option. Firts build the dimension with generation preference and after build with parent/child. I have two rules files, one with generation and other with parent/child these order, but when run the rule file for parent/child the memebers not add a dimension, why???? Saludos.

Hi Saludos, I have two rules files, one with generation and other with parent/child these order, but when run the rule file for parent/child the memebers not add a dimension - u mean to say in the outline the dimension name is not being created or the children for the dimension is not created. If it is first one then check whether you mentioned the rul file name or the outline name to create the dimension name. If the issue is the 2nd one then check whether you had chosen the method of dimension memeber creation (generation/level/parent-child). The default is Generation build. Hope you got some idea, if i understood the problem in the right sense. Regards R.Prasanna

Parent-child hierarcy - row level security

Hi,
Im using OBI 11.1.1.5 and have a problem about row-level security in parent-child dimension.
I have created a parent-child dimension, simlar to:
a1
--a1.1
----a1.1.1
----a1.1.2
--a1.2
----a1.2.1
By using a session variable 'SESVAR1', I want to restrict the visible hierarcy. For instance user 'a1.1' should only see:
a1.1
--a1.1.1
--a1.1.2
To do this I created a parent-child closure table with the whole dataset. Then I created a physical table using select statement with my session variable in repository. Whenever I viewed data in repository, it showed the correct set.
I created a parent-child dimension, using the original parent-child closure table. But since current distance values are different from the original hierarcy, I can not managed to build a security such a security system with this method.
How can I build a security system, that a member can only see its child hierarchy only?
Thanks for answers and links...

According to searches I made in support.oracle and google, it seems that it is not possible to view just a branch of a parent-child tree. Because the closure table is static. Therefore, you can not change the distances of objects dynamically.
This parent-child ability is very frustrating for me. As I understand, parent-child dimension ability can only be used in read-only sources. Any filtering or dynamic changes does not seem possible in this structure. Any changes on parent-child table requires parent-child relation table to be rebuilt.
I couldnt find any functionality of indexcol or choose functions in parent-child dimensions. I think they can only be used in level based dimensions.
Any comments appriciated..

Parent Child Hierarchy (N Level Hierarchy ) in BI 4.0

Hi ,
We have following table structure . We are trying to create parent-child hierarchy and implement drill on the same .
We are using Oracle database as RDBMS.
e.g.
Child Key    Parent Key
1
2                 1
3                 1
4                 2
5                 2
6                 3
7                 1
8                 5
Now based on this table structure , if we create hierarchy using parent key and child key , we should be able to drill from 1 to {2,3,7} directly.
further when i click on 2 , we should get {4,5 } as resulting rows.
At the same time drill-down should not work on the values which are not parent of anyone (i.e. Leaf Node). e.g. 4, 8, 7, 6.
Can anyone please let me know how can i achieve the same result by building hierarchy or any work around ?
Regards ,
Jeevan Chaudhari

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)

Converting numeric level identifier into Parent/Child format to load.

I am unable to receive meta data in parent child format from a ERP source system and need to load these into Planning through ODI. Each member is identified with a numeric level indicator. Is there any wasy to convert this into Parent/Child format using the level indicator?
Thank you.

If you are using oracle you could look into using the "Connect by prior" function.
Cheers

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.

Getting parent-child data into an Oracle level-based OLAP hierarchy

We have some organisational data which we need to represent in an Oracle OLAP 10g dimension, preferably populated using Warehouse Builder.
The organisational hierarchy is listed as parent-child pairs, and is both ragged (unbalanced) and skip-level (noncovering). This would lend itself to a value-based hierarchy, but our client would rather we use ROLAP rather than MOLAP, i.e. avoid the use of an Analytical Workspace, which rules out the use of a value-based hierarchy.
Is there a straightforward way to populate a level-based hierarchy using parent-child pair data, and if so how can it be done?
Pointers to tutorials would be welcome, especially if they use Warehouse Builder.

If you have an Oracle DB have a look on the CONNECT BY PRIOR functionality.

Find parent/child relationships At More Than 2 Levels

Hello,
Does anyone have a solution to find parent/child relationship for data more than 2 levels deep?
I have a solution when there's a simple parent-child relationship but not when there's a grandparent-parent-child relationship or deeper.
Ex. I have a table company_parent_child that stores the relationship betwen a company and it's direct parent.
create table TEMP_COMPANY_PARENT_CHILD
PARENT_ID NUMBER(10),
COMPANY_ID NUMBER(10)
insert into TEMP_COMPANY_PARENT_CHILD values (1, 10);
insert into TEMP_COMPANY_PARENT_CHILD values (1, 11);
insert into TEMP_COMPANY_PARENT_CHILD values (1, 12);
insert into TEMP_COMPANY_PARENT_CHILD values (2, 13);
insert into TEMP_COMPANY_PARENT_CHILD values (10, 100);
insert into TEMP_COMPANY_PARENT_CHILD values (10, 101);
insert into TEMP_COMPANY_PARENT_CHILD values (10, 102);
insert into TEMP_COMPANY_PARENT_CHILD values (11, 103);
1->
___10->
______100,101,102,
___11->103
Companies 100, 101 and 102 are under parent 10 and grandparent 1.
I need to create such a view or another temp table so that when I pass the parent ID, I will pull all the children on all levels. In addition, and this is the tricky part, when I join this new temp table or view to another data table without any parameters, the data should not be duplicate, ie. each company ID should appear only once.
create table TEMP_JOIN
company_id number(10),
order_id varchar2(10)
insert into TEMP_JOIN values (100, 'a');
insert into TEMP_JOIN values (101, 'b');
insert into TEMP_JOIN values (102, 'c');
insert into TEMP_JOIN values (103, 'd');
insert into TEMP_JOIN values (10, 'e');
insert into TEMP_JOIN values (11, 'f');
insert into TEMP_JOIN values (12, 'e');
insert into TEMP_JOIN values (13, 'f');
Thanks.

start by learning CONNECT BY/START WITH. once you've
written a query to read the grandparent-parent-child
relationship, then come back with more questionsYes. we did look heavily into connect by/start with, in fact along with "connect_by_iscycle","connect_by_isleaf","connect_by_root" as well.
Our dilemma is that when a joint is made between those two tables mentioned above TEMP_COMPANY_PARENT_CHILD and TEMP_JOIN, we are not able to create a view that would contain distinct company_ids, each mapped to a unique order id.
The problem is we cannot have this type of joint when there are "n" level relationship between companies (or company_id). Basically, I think we should have our unique order id mapped to a unique key. This unique key should be a specialized key that we can know at anytime the entire path of the ancestry which we can know by sys_connect_by_path(company_id,'/') path.
How do we know which path to take. The best bet is to "connect_by_isleaf" and just have the distinct "deep" path which form the specialized unique key. If you need help on this let me know. (A hint, sort by LEVEL and then do a rank after partitioning by company id and then filter the records by rank = 1, try this one!!!)
So, we will eventually have a joint (say Table X) like
PATH ORDER_ID
/1/10/100 a
/1/10/101 b
/1/10/102 c
/1/10 e
/1
/1/11/103 d
/1/11 f
I think this is the best view we can have to maintain a joint with no repetition along PATH as well as ORDER_ID. If you have any other thoughts, let me know.
Then you query by path using INSTR to pull records by company_id.
for example, if you want to get all the children for company_id "10" you would just say
select * from X where INSTR(PATH,10,1,1) <> 0
or if you want to get all the children for company_id "11" you would just say
select * from X where INSTR(PATH,11,1,1) <> 0
What do you think? Has anyone used the path information for traversing the tree? Or is there any article that tells us how to make effective use of sys_connect_by_path(company_id,'/') path.
Thank you. Hope it made sense!
