Essbase Cube Hierarchy Types in OBIEE 11g

All,
Is there any documentation anywhere that explains what the different hierarchy types are for Essbase? I see the following listed, but am totally confused as to what each means and when it should be used.
1. Fully balanced - Basically a flattened out equal level, no skips, hierarchy
2. Unbalanced - ?
3. Ragged Balanced - Isn't this an oxymoron?
4. Network - ?
5. Value - I'm seeing in blogs this is basically a Parent-Child; if so, what are 2 and 3 used for then since you can pick Ragged and Skipped Levels on the BMM layer?
At this point, I'm trying to test out the DMDemo cube from 9.3.3 and have the Fully balanced dims working fine. I'm putting my Accounts as Value, but it won't drill past the 2nd generation. I'm putting Products as Unbalanced, but I'm not sure if this is correct. When I put Products as Ragged balanced it works, but lets you expand past where there actually is a level to the maximum depth (giving you a blank box), which doesn't look pretty at all.
Any direction on this will be greatly appreciated as the first one is the only type I can get to work correctly.
Thanks in Advance,
Josh

All,
After re-reading the documentation, I see that only Balanced, Unbalanced, and Value are supported for Essbase. I went ahead and setup the DMDemo out of our 11.1.1.3 environment the same way I did the 9.3.3 and here's what I found. Unbalanced works when setup exactly the same as it is in 9.3.3, I dont' see any issues with it. Value on the other hand, still doesn't seem to work correctly as I can still only drill down one level. I decided to switch Accounts to Unbalanced to see if it works and it appears my cube is working totally fine in OBIEE finally. To me, it seems as though it's just a version compatibility issue. Has anyone else ran into this so far? Also, I still don't understand what the difference is between Unbalanced and Value besides the fact that Value only gives Total and Detail levels on the hierarchy. Hopefully this helps someone else!
Thanks,
Josh

Peoplesoft Trees as Hierarchial Columns in OBIEE 11g

Sorry for a duplicate posting. Logged in as a normal user with random number. I know how much people hate it. Logged in as myself now.
Hi,
I have extensively searched using Google or 11g docs but could not find a proper solution to using Peoplesoft trees in form of hierarchial columns in obiee 11g. Can the rpd of obiee 11g be designed to view the Peoplesoft tree structure( as it is in Tree manager in Pplsoft) as hierachial columns in obiee 11g? I am sure hierarchial columns as a 11g feature are not just for visual representation in tree format but also can be viewed in Answers and queried against it,am I right?
Anybody who has worked on trees and OBIEE 11g hierarchial columns? Ahsan/Navin??
Thanks,
Dan

I have not used the 11g hierarchical columns for PSoft Trees but I can think of a glaring reason NOT to do this..PERFORMANCE. If I understand correctly, 11g issues a group by and Union as you traverse this type of structure and PeopleSoft trees have a number of tables to represent the actual TREE. I cannot possibly see how this can be effective especially with a large scale BI Apps DW? This is part of the reason the trees get flattened out via the OOTB ETL adaptors for PSoft.

Hierarchy Prompts in OBIEE 11g

Hi All,
I have an Issue with Implementing Hierarchy Prompts in OBIEE 11g. I understand that Filters on Hierarchy Prompts can be applied in Selection steps and cannot be viewed in the Physical Query as such. However, what happens is, the Hierarchy prompt only gets applied when the hierarchy is displayed in the report.It is not applied even when it is present in the excluded section. So, it works only when it is displayed in the report. Is this correct? Is there any workaround for this?
Any help on this would be much appreciated
Regards,
Venkatesh

If the column set to prompt no matters what (column is present,or not, excluded or hidden) the prompt should work.
Check it again something might gone wrong.
If it is helpful, please mark as correct or helpful

Install Essbase 11.1.2 and OBIEE 11g on one and the same Box (Linux 64bit)

Hello
Did anyone already try to get Essbase 11.1.2 and OBIEE 11g installed on the same box? In my case I am trying it on OEL 5.5 64bit.
How did you proceed?
First Essbase or first OBIEE or have WLS installed standalone first?
Encountered any hurdles?
Thanks for any hints or links.

let me check... yeah u can do that dude i cant tell u how to do it but i can give u some idea
try to see properties file or db files for web logic ...i think it where the port number are stored and in war file is where multiple instance info is stored
iam sure that u can create multiple instance as long as u give different ports (yeah u have to other wise u cant config it :))

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 ?

How to create the relationship between ESSBASE 11 and DM in OBIEE 11G?

Hi Experts,
I have one requirement that there is one property table named 'Store Master' in DW,and it contains a lot of attribute, such as Open Date, Close Date, IS 24 Hour etc.
But another data source is essbase and based on this source, I create all reports.
In ESSBASE, it has one dimension and hierarchy Location, and it has four level, Country(L1),Region (L2),Province(L3),Store(L4)
So I want to know how to create the relationship between Location (ESSBASE) and Store Master (DM).
I try to create one relationship in physical layer between Gen4,Location and Store, then drag the open date and close date into Location Dimension in BMM,then Presentation Layer.
When I drag column 'Open Date' ,'Gen4,Location ' and 'Sales' into reports, it will generate the following error message:
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 14020] None of the fact tables are compatible with the query request Dim Region.Store Open Date. (HY000)
However, when I remove the column 'Open Date'. it will be ok
So what I missing the steps? Please help me. Thanks.

>
'2. Now, pull the 'Store' column from relational DB onto the Gen5, Location column from Essbase. This action now creates, two logical sources for your 'Store' column.'
If the length from different data source is not same,such as 1001(DM),L_1001(ESSBASE), can I drag the 'Store' column from relational DB onto the Gen5, Location column from Essbase?
I think it does not work.Right?Hi,
I am not sure if you are talking about the length(as in varchar(128)) of the member value being different in different sources, or the member itself is different in both the sources.
I am still assuming, that you are referring to the members not same in both the sources.If it is, the whole concept of federation is based on conforming dimensions. So, it needs that the same dimension information is present in both the sources and then only, you know we can analyze the numbers based on this dimension. So, either the dimension being different in both sources, or the members not present in both the dimensions might lead to incorrect numbers.
So I select Store Attributes in relation DB and Location in ESSBASE in physical layer, then create the physical join, such as right("Hour Sales"."H_Sales".""."H_Sales"."Gen6,Location",4) = "Authorization".""."EDW"."T_EDW_MDM_STORE"."US_CODE", then drag the OPEN_DATE and CLOSE_DATE in relation DB to Location in ESSBASE in BMM,finially drag them into presentation layer.We create physical layer relationships, to send over the same relation to the underlying database during querying. So, creating a physical relationship between essbase cube and relation database would not help here.
When you set up this federation, BI Server sends individual queries to each source and maps the conforming dimension members internally.
Hope I was clear, and this helps.
Thank you,
Dhar

Essbase as a source in OBIEE 11g and using lookup to Relation database

Hello All,
We are trying to implement Essbase as primary source for our obiee 11g repository and using relational database as secondary source of data.
I was using a lookup functionality in repository to lookup value from one of the Essbase's Dimension's attribute to relational database, however, there is error when testing this in OBIEE Dashboards.
And tried to look this error in support.oracle and googled it but was not able to find anything on it.
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 46008] Internal error: File server\Query\Src\SQLookupUtility.cpp, line 145. (HY000)
Have you had any such issue and how can we pass this issue?
I am trying to find if there are any quick resolution before going to oracle support.
TIA.

Changing a field type in OBIEE 11g

Hello. I am new here, and new to OBIEE. I have read some of the tutorials and created a repository, but will not get formal training through Oracle until next week.
I have a simple request from a user that I need to do, and I am not sure how to do it.
Background:
There is a field, COUNTER1, in my physical layer that is Char(9).
In the BMM layer, the field gets counted, so it becomes HEADCOUNT and gets defined as COUNT(COUNTER1), and it is an INT field.
Same in Presentation Layer.
The user wants to be able to see decimals, so I need to change it to a DOUBLE type field.
My Question:
Can I simply change the field type from INT to DOUBLE in the Presentation and/or BMM layers, or is it more involved than that?
Thank you for any help that you can provide.

Create new logical column in BMM and in column source tab check the option "Derived from existing columns using an expression" in the expression use below formula
1.0d * COUNTER1 --> It converst to double automatically
where counter1 is count(physical_column) which is int

How the hierarchy works in obiee 11G

Hi All,
Normally in 10g , when we set detail level then it gives data of lowest granularity. but here in 11g i created one dimension in dept table . and took two salary columns of emp and one i set it to total and other as detail .
when i took two columns i did not get data as expected (The way we get in 10g)
How it works in 11g??
Is there any document/blog .. please help.

check this
The Port number is the AdminServer Port Number of the domain. This is where the EM app will be targetted and deployed. If you choose all defaults and have like a Simple Installation of BI Software, then you should have one Server named AdminServer running at default Port: 7001.
To really confirm exactly, open you config.xml file which is under your domain root folder/config/config.xml file. Search for "em.ear" and see to which server it is targetted, generally it will be AdminServer (<target> tag entry). Now from the top search for "AdminServer" in the same file. You should see an entry like shown below. SSL Port is 7002. If you do NOT see <listen-port> tag, it means it is using DEFAULT Port which is 7001. But if you do see this tag, use that port number. Do not get confused with <ssl> port. Every domain have normal and ssl ports and most of the times we use normal port.
<server>
<name>AdminServer</name>
<idle-connection-timeout>1000</idle-connection-timeout>
<period-length>200000</period-length>
<idle-periods-until-timeout>20</idle-periods-until-timeout>
<dgc-idle-periods-until-timeout>21</dgc-idle-periods-until-timeout>
<ssl>
<name>AdminServer</name>
<hostname-verification-ignored>true</hostname-verification-ignored>
<listen-port>7002</listen-port>
</ssl>
<machine>RJEGGA</machine>
<listen-address></listen-address>
<server-diagnostic-config>
<name>AdminServer</name>
<diagnostic-context-enabled>true</diagnostic-context-enabled>
</server-diagnostic-config>
</server>
So, try, http://youradminserverhost:adminserverport/em
NOW, if you get like Page Not Found, or do not see entry from em.ear file in your config.xml file, this means your domain is not having EM app deployed.

Importing Essbase cube in OBIEE

Hi Experts,
I have imported the Essbase cube in to the OBIEE physical layer but the attribute dimension and the base dimension are not mapped.
Please let me know how I can map the base dimension and the attribute dimension of Essbase cube in BMM layer.
Thanks in advance

Thanks for all your responses.
Apparently it turns out that the Accounts dimension Hierarchy needs to be changed to type 'Value' for the measures to start working.

Issue in integrating Essbase cubes with OBIEE

Hi
I am trying to use Essbase cubes as datasource in OBIEE for generating reports,but the issue is in generating , No columns in fact table of cube in BMM layer.
Outline of cube is
Revel(cube)
(Hierachies)
Time Time <5> (Label Only)
Item <54> (Label Only) (Two Pass)
DepInst <20> (Label Only)
SFA_Flag <2>
Deduction_Flag <2>
Rating_Category <6>
PD_Band <9>
Product <17>
Entity <4>
CR_Agency <5>
I am confused how to generate reports without measures in fact table.
Regards
Sandeep

Hi Sandeep,
in that case it's as I thought:
Or did you just not specify any measure hierarchy?You tried this...
In BMM layer i made this dimension as fact and tried to create reports but not use....which isn't the way. First of all your cube seems to be built quite bizarre since it doesn't even provide a default measure hierarchy so I'd have your Essbase guys check that.
As for the OBIEE side: the key is the physical layer. BMM's already too late. In the physical cube object, you must define one of the hierarchies as the measure hierarchy (since your cube doesn't seem to provide it; see above):

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

So basically this means that if I build a parent child hierarchy on table A having the stucture like
--David (Manager)
-----James (Off1)

Build OBIEE 11g repository accessing Essbase problem

When I use OBIEE 10g to import Essbase cubes metadata, the measures are displayed as 'physical cube columns' in physical layer; however, when I use OBIEE 11g to import the same Essbase cubes metadata, these 'physical cube columns' disappear (i.e., I cannot see profit, margin, etc. anymore) but rather, the measures are shown with 'physical dimension' with a hierarchy structure (up to Gen4 measures).
The implication is that when I drag the structures to BMM layer and then presentation layers, I am not able to select any measures in the presentation layer.
Are there anyone who can help me solve this problem?
Thanks a lot.

Hi user,
Obiee 10g had a big problem importing essbase measures. In order for you to create a measure you needed to make the measure dimension and "Account" type dimension which would mostly be the Scenario dimension rather than the Account dimension.
Obiee 11g allows you to import the account dimensino and decide whether to treat it as measures or as a dimension. Once the cube is imported,right click on it and select "Convert measure dimension to flat measures". This will resolve your problem.

Flattening Essbase Measures in OBIEE 11g

Hi all,
I'm using OBIEE 11g. After importing a cube from Essbase to the physical layer in the RPD, I'm choosing "Convert measure dimension to flat measures" to flatten the measures. Now I have all the measures as a flat list. However, the "Measures" dimension/hierarchy still exists in the physical layer. I find this strange.
Then when I drag the cube to the business model layer, that "Measures" dimension/hierarchy isn't brought to the business model layer. I think this is correct, because the measures are already flattened, therefore there should not be any measure dimension/hierarchy in the business model layer.
My questions:
1. If the measure dimension/hierarchy is not used anymore in the business model layer, why does it still exist in the physical layer?
2. What is the impact if I remove it from the physical layer? (Note: I tried this, so far no error, but not sure if later on I will encounter error because of this)
Any thoughts on this? Thank you very much!

My questions:
1. If the measure dimension/hierarchy is not used anymore in the business model layer, why does it still exist in the physical layer? This is normal behavior with OBIEE 11g. It will still be there in physical layer.
2. What is the impact if I remove it from the physical layer? (Note: I tried this, so far no error, but not sure if later on I will encounter error because of this)There shudn't be any future problem incase you wanna delete it during developemet BUT think of a situation during Incremental Essbase Cube Import to OBIEE which was not possible in 10g (straight Forwardly).
I'd suggest to keep it as it is in Physical Layer inorder to avaoid any future issues/enhanced requirements.
Hope its clear Stewart !!
