Query in business model

hi gems...
this question is regarding a doubt while seeing a business model.
in the physical layer there are lots of tables among which three physical tables are "transaction_master", "instrument_master", "asset_indicator".
there is join between the "transaction_master" and "instrument_master" but there is no join between "transaction_master" and "asset_indicator".
But in the business model, while making the logical "transaction_master" table, the developer has dragged a column from the "asset_indicator" table into the "transaction_master" table in the business model layer....when there is no direct join between those two tables in the physical layer, then how that step has passed the global consistancy check???
the reports made from that business model are working fine.
How is it possible...
I observed that there is a indirect join between "transaction_master" and "asset_indicator" tables through the "instrument_master" table...means "transaction_master" has a direct join with "instrument_master" and "instrument_master" has a direct join with "asset_indicator"...but i dont know whether my thought is correct or wrong...
please help me in understanding this concept...thanks in advance...

Not in BMM layer but you can achieve this in Physical layer.
In physical layer --> Create New Physical Table --> select table type as Select

How can I use Server level variables in a business model based report

hi gems..
I have declared one server level variable in the BI Analytics repository.
Now I have made one business model based report.
In one column I want to use that server level varible.
I go to the formula tab of that column and then clicked on variable--> session --> put the name of the variable and click ok.
But when i viewed the report, it is not showing the dates, rather it is showing the date format I chosed i.e DD-MMM-YYYY.
please help..

actually the previous problem got resolved...
Now when I am trying to apply a filter on a particular column using that server variable, then it is showing that the varible has no value definition.
I have clicked on the filter tab of that column-->add-->variables-->session variables-->then I put the name of the variable-->click OK.
the following error is comming-
Error Codes: YQCO4T56:OPR4ONWY:U9IM8TAC:OI2DL65P
Odbc driver returned an error (SQLExecDirectW).
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 23005] The repository variable, Variable_name, has no value definition. (HY000)
I have made that server variable from manage-->variables-->(right click) create new initialisation block-->gave the name and wrote the query and aslo gave the connection pool name and test that and it worked fine..

Purge Cache for a Specific Business Model

Hi everyone,
I have a obiee(11) report purging all cache entries (as Call SAPurgeAllCache()). Is there a method to purge cache partially for specific business model entries and not to purge all the cache ?
Thanks ...

Hi,
To selectively purge, you could use SAPurgeCacheByQuery, SAPurgeCacheByTable or SAPurgeCacheByDatabase. Alternatively, Event Polling Tables may help. See http://docs.oracle.com/cd/E23943_01/bi.1111/e10541/querycaching.htm#i1005542 and http://docs.oracle.com/cd/E23943_01/bi.1111/e10541/querycaching.htm#i1010207.
Also see the section on BI Server caching here : http://www.rittmanmead.com/2013/03/optimising-obiee-performance-tuning/
SET VARIABLE DISABLE_CACHE_HIT = 1
It will purge the cache for that report.This is just wrong. DISABLE_CACHE_HIT only DISABLES cache use for the query execution, it does not PURGE it
You may go for this DISABLE_CACHE_SEED for more info http://docs.oracle.com/cd/E23549_01/bi.1111/e10540/variables.htm
What's the point of DISABLING use of the cache, if the OP wants to use the cache?
set the cache persistence time for the related physical tables. so based on the time interval u set, at that time specific tables only will get cache purged.This is only the time from which the entry got loaded into the cache, so is not a good way to manage the purging of the cache usually - because it has no relation to when the data got loaded to the database

OBIEE 10g repository - Business model - logical table to physical table, column mapping is empty

Hi, I am really new to OBIEE 10g.
I already set up a SQL Server 2005 database in Physical and import a view vw_Dim_retail_branch.
The view has 3 columns: branch_id, branch_code, branch_desc.
Now I want to set up the Business model to map this physical table (view).
I created a new Business model
Added new logical table Dim_retail_branch
In the sources, added the vw_Dim_retail_branch as source table.
But in the Logical table source window, column mapping tab, it's blank. I thought it should be able to identify all the columns from vw_Dim_retail_branch, but not. The show mapped columns is ticked.
What should I do here? Manually type each column?

HI,
Just you can drag and drop the columns from physical layer to BMM layer.
Select the 3 columns and drag and drop it to the created logical column in BMM layer.

How to copy one Analysis/Report in Business Model A to Business Model B?

I have created a Business Model, Presentation layer in my RPD. I have many subsequent reports/analysis for that BM. Now, i have created a second BM/Presentation layer, in the same RPD, which uses a new set of identical tables (columns and table names, etc... all the same, but different data). So, without re-created each report in Analysis, i just want to copy some of those reports/analysis so they will use my 2nd BM instead of the first. Can this be done, and how?

I'm retracting my comments for now -- this may be due to a column ALIAS which isn't present.
I will re-post after I investigate that a bit.
--- Original ---
Kalyan,
Not sure if you had any difficulties in this method. When i try it, i get the following error below. I've checked my names - the names "Periods" and "PERIOD_ID" are identical in both my subject areas. They refer back to aliased tables which ultimately point back to the same physical table. It's unclear to me why i am getting the unresolved column error, but i'm still trying to sort that out.
Odbc driver returned an error (SQLExecDirectW).

How to add a stand alone table from Physical layer to Business Model

Hi,
I have tables from 2 different database sources in my Physical Layer.
My Business model currently uses only tables from one database. from my second database in teh physical layer I need only one table and that will be a stand alone table, to my Presentation layer.
1. Does it have to go through my Business layer or can it be directly added to the Presentation layer. What are the steps?
2. Can I restrict the permissions on that stand alone table only to the administrator?
Thank you.

1)create a view with single column using the sql (select 1 from dual) in physical layer and join it with the table using complex join in physical layer (1=1).
Move that to BMM, set the column as key in both physical and bmm layer.
2) You can restrict the access for the table presentation layer
Double click the presentation layer table -> Permission -> there you can restrict the access by user or group
Thanks,
Vino

Business Model and Mapping layer

I am trying to create a logical dimension table by dragging the corresponding table from the physical layer. However, in the business model layer it shows up with a yellow icon indicating it is a logical fact table. Please help me how I create a logical dimension table in the business model layer. Not sure what I am doing wrong here.
Thanks.

Hello Saichand,
No I did not. Do I have to create joins even when I am dragging this object from the physical layer? Let me read and learn how to create the joins. I will get back if I will have more questions.
But, thanks for the quick response. As you can see this is the first time I am trying to modify the business model layer.
Thanks.

Alternative approach to tree business model

Hi JHS Team,
When generating tree-forms with JHeadstart, we need two VO instances in the model for each node we want to present: one for rendering the Tree and another to show on the form, after the user selects a node.
I understand that this is necessary for the case when the user clicks on one node which father node isn't the current row of its corresponding View Object, and so in such case the form couldn't find the current row and show the correct data.
I'm still using the 10.1.2 version, but I checked the 10.1.3 documentation and this model requirement is still there.
I tried another approach to this issue, which consists of using the very same VO instance for trees and forms: in every level, I render the node with every Iterator used in the previous levels and each corresponding row key for every previous levels. When the user selects a node, in that node link I have every Iterator I need to seek and every primary key I need to search for, so I can really reconstruct the path used by the user to seek that node.
So, the benefit is that I don't need a root VO in the AM for every node I need to present as a form. In huge trees, this really simplifies the model construction and its maintanance.
In 10.1.2, the runtime library (JhsDataAction) is already prepared for this, so I would like to know, if possible, the reasons why this is not used already by default (maybe performance?). If there is a reason to mantain the two VO instances in 10.1.3, could it be changed to allow us use the same instances as an alternative to simplify models, and generate the JSF pages working accordingly?
Thanks a lot!

Hi Steven,
Many thanks for the explanation. I agree with you that the current implementation is easier to understand, but I think it is only from the point of view of a programmer who understand some concepts of ADF business model. When you're a beginner, it's more difficult and less intuitive (or at least it was for me some time ago :-))
I can say that in our project we have 4 very large trees in the same Application Module (since they need to be present on the same project as they're all related), and in each level we have at least 3 or 4 "details" VOs we present in the form, so the final model is really huge and really difficult to maintain. It was surprisingly easy to change the UIXs to the other approach, however, so I asked myself if this was tried already. Thanks for warning me of the unpredictable problems, I'll see if we have any.

Link Join Concept In Physical and Business Model Layer

Hi,
As we know that we could make join relationship in physical layer and also business model layer in obiee 10g. This is what makes me confuse.
First of all, I tried to follow the tutorial in the oracle learning library center with schema SH as an example.
In the beginning, it is stated that we must make join relationship first in physical layer for all imported tables which are consist of dimension tables and fact tables.
Then, in the business model layer, the tutorial said that we must also make join relationship for the logical dimension table and logical fact table.
So, what's the purpose actually we must make join relationship in business model layer ?
All objects in business model layer are actually mapped from physical layer. So automatically the relationship in business model layer should be available automatically as they are mapped from physical layer.
Maybe for you guys who know the concept well about this difference of relationship, could tell me so I could get the idea of what it is actually about.
Thanks

Physical layer does represent datamodel joins as is in almost all cases.
Federated queries are a best example why joins are implemented in both (Physical & BMM layer) places.
Business model mapping layer is modelled according to your business requirements.
This is where your model MUST be a simple star schema, also where you model your hierarchies based on logical tables in bmm layer, & do appropriate aggregate navigation.
Hope the view points presented will put you in right direction.
mark answers promptly.

Probelm Addind new Table in Physical Layer, Create Dim in Business Model ..

I have completed a task for a dash board, that is running sucessfully.
Now I added a new table in "physical layer", (file->import->from database), table added successfully
Now, I droped this table in "business model", but when I want to create its dimension, there is no any option (when I right click on this table)
there are two cases
case 1:
I did not added modified fact table (with foreign key of new table) in "physical layer" and not in "business model and mapping"
case 2:
I added new table and modified "fact table (with foreign key of new table)" in "physical layer" and "business model and mapping"
but in both cases there is no "create dimension" button to create dimension
Please let me know the how to solve this problem, kindly define it in steps
thanks

Hi thr,
Create Dimensions is only available if the selected logical table is a dimension table (defined by 1:N logical joins) and no dimension has been associated with this table.
In you case, once you have imported the table successfully in physical layer, then join your table to fact table. Drag n drop in BMM under a new logical table and then join it to BMM Logical fact using complex join. Now, if you right click, you see the last option as 'Create Dimension'
Hope you find it useful..

How can i call a business model function?

Hello!
I have a simple problem
A gui view-backing - function call the setUsername by FacesContext und operative Buinding - it works well.
Now i want to call the the function getUsername from a function inside the class EntityImplEx - both classes are in the business model in different class-pathes.
How can I call the function getUsername from AppModule?
package model.app;
public class AppModuleImpl extends ApplicationModuleImpl implements AppModule {
    public String username                = "init";
    public void setUsername(String ss) {
        username=ss;
    public String getUsername() {
        return(username);
package model.entity;
public class EntityImplEx extends EntityImpl {
***************************

You probably don't want to call a function in your UI from your AM.
Doing this will break the MVC design pattern and will make your AM depends on a specific UI page.
The way to communicate between the two is through service methods on the AM that are invoked from the UI layer.

Building data model using business modeler in demantra

Hello.
During this week I've been trying to build a data model using the business modeler but i keep getting an error during the process. My main problem is that I don't really know if i am making the mistake or it is a configuration problem with my demantra install. To begin with I'm trying to build the most simple of the models, 3 files or tables (tryed both) sales, items, and location, all joined by their respectives id's. So If anyone could be so kind to direct me to a tutorial with an example (besides the implementation guide) or a anything like that will be greatly appreciated.
Thanks!
Data tables estructure:
Sales table:
Item_Id|Item_Name|Org_Id|Org_Name|Site_Id|Site_name|sales_date|Quantity
Items table:
Item_Id|Item_Name
Location table:
Org_Id|Org_Name|Site_Id|Site_name
So far I've tryed building the model with one record on each table.
this is the error that i'm getting:
<a href="http://imageshack.us/photo/my-images/832/errornuevo.png/"></a>
Uploaded with ImageShack.us

We currently don't support DataControls based on the ADF BC technology. We will consider such support if there is a strong interest in that use case.
Independent of the IDE's you use, there are ways to expose services based on ADF BC that can then be consumed by the view layer. A Google search will point you to some of the approaches.
HTH. Thanks for your interest in OEPE.

Business Model with 2 fact tables

Hi there
I am trying to get a simple business model working , 2 fact tables, 1 dimension, similar to this example :
http://www.rittmanmead.com/2008/08/resolving-fan-traps-and-circular-joins-using-obiee/
However I keep getting this: [nQSError: 14025] No fact table exists at the requested level of detail:
the tables are:
Incident (dimension)
PK Sequence
Incident Detail (fact table 1)
PK Sequence
FK Problem #
Order (fact table 2)
PK Sequence
FK HDNum
I cant figure out why this doesnt work like the rittman mead example? do they need to have the same column name?
Thanks
Tim

It says the model doesnt contains a fact table.Fact table will have foreignkeys and Measure columns.That link shows the circular joins between tables.There fact table is not there.
See this link for fact and dimensions

Moving Business Model Contents

Hi.
I need to move a business model content into another one without affecting presentation catalog.
I moved the fact table, the dimension tables, and the dimensions (except one that is already present in the destination busienss model).
I've got an error ...
Which is the best way to do it ?
Thanks,
Andrea

You can write click your business model , and choose to duplicate , with or without corresponding Pres. Catalogue.
Otherwise you should be able to shift select, right click copy and paste. You may want to do this in smaller groups, ie fact tables, then logical dims, then hierarchies.
I've also see some joins not get copied before, and importantly, the content levels on LTS's and measures - I've seen those not get copied also.
Hope this helps.

OBIEE 10G - Repository Business Model adding Fact Table

Hi there,
I've tried to search in the forum for problems similar to this one but didn't find any thread that answered my doubts.
I'll try to explain this well (without images it's complicated). Let's assume we have a schema with the following tables:
Dim_1, Dim_2 , Dim_3, Dim_4, Dim_5, Fact_1, Fact_2
Fact_1 is connected to Dim_1, Dim_2 and Dim_3
Fact_2 is connected to Dim_2, Dim_3, Dim_4 and Dim_5
And on the business model of the repository we already have a model with the following tables:
Dim_1, Dim_2, Dim_3 and Fact_1. This was the state of the repository the last time we saved it.
Now i want to add to the business model the table Fact_2 and the Dims that connect with Fact_2. What should i do here?
If i drag from the physical layer only the tables (Dim_4, Dim_5 and Fact_2 since Dim_1 and Dim_2 already exist in the business model) when i check on the business model diagram the Fact_2 table and direct joins i will only see joins to Dim_4 and Dim_5 and not the joins to the two other dimesion tables (Dim_1 and Dim_2). I don't know if OBIEE will still act like these joins are made or if i will have problems when i work on presentation services.
If i drag from the physical layer the tables (Dim_2, Dim_3, Dim_4, Dim_5 and Fact_2) i will see all joins but i will have on the business model repeated tables, something like this:
Dim_1, Dim_2, Dim_2#1, Dim_3, Dim_3#1, Dim_4, Dim_5, Fact_1 and Fact_2
So what's the solution here? Do i have to redo everything i want to add something and this situation occurs? Doesn't sound smart and there has to be a better solution. I know i can redo the direct joins manually but is that the best solution i can look for in this situation?
I hope i was clear :)
Thanks

Hi,
Follow these steps,
1.Drag Dim_4, Dim_5 and Fact_2 to BMM
2.Select (Press Ctrl to select multiple objects)in BMM: Dim 1 to 5, Fact_1 and Fact_2
3.Right click ->Business Model diagram->Selected objects only
4.Give the necessary joins,
Dim 4,&5 joins to Fact1(as 1,2,3 are already joined)
Dim 2,3,4,5 joins to Fact2
5.Check consistency.

Dpka
