Hierarchy with multiple Physical tables

Some time ago there was a post with this subject and I am in need, if you pls, with the same situation:
I am looking for Dim (1) - (1:N)-> Dim (3). And Dim (3) - (1:N)-> Fact.
Suggestion by Mr. Bharath was to, just reduce your snowflake to star in your BMM with Dim (3) as your single LTS. Within the LTS map Dim (1). to Dim (3).
Could someone pls. help me clarifying the suggestion .../
a) Should I use the Dim(3) LTS and how to map Dim(1) ? - I believe we should use a column ? right ? Or just Add the Dim(3) in the LTS tables
Txs. for any hints
Antonio

Hi Antonio,
First of all - try to avoid SNF in BMM.
http://www.oraclebidwh.com/2010/10/obiee-bmm-layer-design-principalsbest-practices/
Comments:
1) You can keep the SNF model in BMM, but if you keep them, then you cannot create an hiearchy with combination of Dim(1) and Dim(3) together as those are two seperate LT.
2) OBIEE will take the shortest path in forming the query. But, if there are multiple shortest path, then OBIEE will use the latest relationship ID in creating the execution plan. For example: Dim (1) is joined with Dim(3) and Dim(4) and your report pulls - Dim(1) and Fact(1), then the shortest path can be either through DIM(3) or Dim(4), and for such scenario's OBIEE will use the ID (latest ID). Say Dim(4) was the latest join - then OBIEE will use Dim(4) in the query to join with Dim(1).
3) I actually do not undertstand your issue here - if you are creating an Hiearchy using Dim(1) and Dim(3) together, then why don;t you pull all the fields from Dim(1) into this LT. And in your presentation create folders if you want both the dimensions to be displayed seperately.
If you are trying to understand and explore OBIEE - then go ahead play with all possible ways you could think off.

Bharath

How can build BMM with multiple fact tables

HI Gurus,
I have 4 fact tables and 18 Dimension table. Dimension tables have links with multiple fact tables. i have created physical joins in Physical layer. Now my questions is how can i create Business Model with multiple fact tables.
i mean should i create 4 fact tables as logical tables and logical keys ? Then i have to move all dimension tables in to Business model?
i am new to OBIEE. i gone through tutorial it is showing with one fact and multi dimension table. Should i do follow same style with multi fact tables.
Please help me. Thanks in advance for your support.

Thanks for your response.
I had drag all tables from the phisical layer to Business Model. then i have deleted all links and recreated complex joins with default values.
now i have some revenue amont columns in fact tables.
my question is should i should i create aggregation ( like Sum..) for those columns? is it must ?
please let me know thank you very much

Joins with multiple fact tables

Hi Experts,
i have one doubt in joins
we have two dimensions D1 and D2,
D1 is having A1 and A2 columns
D2 is having B1 and B2 columns
two facts F1 and F2 these are joined like D1 to F1 D1 to F2 and D2 to F1, D2 to F2
D1----->F1
D1------>F2
D2-------->F1
D2-------->F2
if i selected A1 and B1 in a request from which FACT table will get the data and why can you please explain
please help me
reg,
Jell

Hi All,
I have a similar requirement where I have 4 multiple fact tables and we can't combine all those facts into one single fact table. In that case how can a query work with multiple common and uncommon dimensions and measures from multiple fact tables, if it doesn't work that way - can you please explain how can we expect a query to work with multiple fact tables.
For eg: D1– Dim
D2 – Dim
D3 – Dim
D4 – Dim
F1 –Fact
F2 – Fact
F3 – Fact
D1 -> F1
D2 -> F1,F2
D3 -> F2
D4 -> F1, F3
In this case if we want to query from D1,D2,D3, F1, F2 or D1,D2,D3,D4,F1,F2,F3. Kindly please explain how it can be modeled in BMM or what are the limitations. I have done with two fact tables in past and didn't had issues but this is kind of a vast implementation. Your help is appreciated.

Using multiple physical tables in a single logical dimension table

I have two physical tables that are related on a 1 to 1 basis based on a natural key. One of these tables is already part of my RPD file (actually, it is the W_EMPLOYEE_D from the Oracle BI Applications). The second table contains additional employee attributes from a custom table added to the data warehouse. Unfortunately, I don't seem to be able to display ANY data from this newly added custom table! I'm running on OBIEE 11.1.1.6.
Here's what I've tried to do. Lets call the original table E1 and the new one E2. E1 is part of the repository already, and has functioned perfectly for years.
- In my physical model, I have imported E2 and defined the join between E1 and E2.
- In my logical table for E1, I've mapped E2 to E1 (E2 appears as a source), set up an INNER JOIN in the joins section for E1 and added the attributes from E2 in the folder
- In the SOURCES for this logical table, I've set the logical level of the content for E2 appropriately (detail level, same as E1)
- In my presentation folder for E1, I've copied in the attributes from E2 that were included in my logical table
Consistency check runs smoothly, no warnings or errors. Note: E2 contains hundreds of rows, all of which have matching records in E1.
Now, when I create an analysis that includes only an attribute sourced from E2, I get a single row returned, with a NULL value. If I create an analysis that includes one attrribute from E1 and one from E2, I get all the valid E1 records with data showing, but with NULL for the E2 attributes. Remember, I have an inner join, which means that the query is "seeing" E2 data, it is just choosing not to show it to me! Additionally, I can grab the query from the NQQuery.log file - when I run this SQL in SQL*Developer, I get PERFECT results - both E1 and E2 attributes show up in the SQL - the query engine is generating valid SQL. The log file does not indicate there are any errors either; it does show the correct number of rows being added to cache. If I create a report that includes attributes from E1, E2 and associated fact metrics I get similar results. The reports seem to run fine, but all my E2 attributes are NULL in Answers. I've verified basics, like data types, etc. and when I "Query Related Objects" in the repository, everything looks consistent across all 3 layers and all objects. E2 is located in the same (Oracle) database and schema as E1, and there are no security constraints in effect.
I've experimented with a lot of different things without success, but I expected that the above configuration should have worked. Note that I cannot set up E2 as a new separate dimension, as it does not contain the key value used to join to the facts, nor do the facts contain the natural key that is in both E1 and E2.
Sorry for the long post - just trying to head off some of the questions you might have.
Any ideas welcomed! Many thanks!
Eric

Hi Eric,
I would like you to re-check on the content level settings here as they are the primary causes of this kind of behavior. You could notice that the same information might have written down in the logical plan of the query too.
Also, as per your description
"In the SOURCES for this logical table, I've set the logical level of the content for E2 appropriately (detail level, same as E1)"
I would like to check on this point again, as if you had mapped E2 to E1 in the same logical source with an inner join, you would get to set the content level at E1 levels themselves but not E2 (Now, that E2 would become a part of the E1 hierarchy too). This might be the reason, the BI Server is choosing to elimiate(null) the values from E2 too (even you could see them in the sql client)
Hope this helps.
Thank you,
Dhar

Smart form problem with multiple pages & table problem

Hi experts,
I have a problem with my smart form with multiple pages
Situation: I have a smart form that ALWAYS has at least 2 pages. In one page the quotation, in the second page (basically this is the 3rd page as the 2nd page is optional) the terms and conditions. Sometimes however, when there are many items in the quotation more than 1 page is needed for the quotation.
The (optional) second page of a quotation has a different header than the first page of a quotation. So I made a second page with 2 secondary windows (where the header texts are in). The main window is after the secondary windows and has to finish the quotation.
The problem is that my headers of the second page are never printed, it stays a blank space. The table however does continue and is printed.
Another problem I have is that I have a table (with the quotations) with 6 columns. The first 2 columns are displayed correctly but once the 3rd column the columns are shown on a lign below.
Regards,
PJ

I would suggest another approach to this problem.
Use just one page. For the headers on the first page, use a secondary window and on the conditions tab, choose the additional event - Only on First Page.
For the different header on the second page, create another secondary window on the same page (probably even overlapping the first header on your layout). But in this one, on the conditions tab, choose the additional event - Not on First Page.
The table should flow as you would be using the Main window for this one.
As for columns, if they are too wide and wont fit in the same line, it would move to the next line. So you would have to re-adjust the line width and test.
Hope this resolves your problem.
Regards,
Ancy

We don't know the "query on Importing data from Microsoft Excel to Oracle Database (Multiple Data Tables). "
We don't know where you posted said query.
We don't know what "some answer and reference" you received "from the forum."
We don't know what it was that your "Oracle consultant and representative from Oracle Malaysia" said was "impossible".
So on what basis are we supposed to "help or direct" to "to an expert that can help "?

Help with universe with multiple related tables/loops

Post Author: bradwist
CA Forum: Semantic Layer and Data Connectivity
Hi. I am relatively new to Business Objects and have been putting together some universes for our use. Most things I can accomplish well enough. However, I've run into an issue that I think fits within this topic. I've got several related tables and I'm looking for the best way to construct the universe to support our queries. The best way to describe them is to say that the database has a table of Person records, and a table of Relationships. One Person may be related to another Person in a number of ways (sibling, spouse, parent, etc). This can be pictured as Person Relationship ID -
< PersonID -
< RelatedPersonID or Person1 -< Relationship >- Person2 where Person1 and Person2 really both point to the same physical table. I believe these tend to lend themselves to Aliases. However, each Person table really has a number of subordinate records in tables (addresses, phone numbers, etc). Address1 >--- Person1 -< Relationship >- Person2 ---< Address2 While this can be done (and I've done so), it's difficult to explain to some analysts why this construct is needed in the universe in order to answer a question like: Give me all of Bob's Siblings, their ages, and their addresses. This is a simplification, as our structures actually include other types of Entities (Person, Business, Government, Organizations), all of which can be related to one another. Is there a way that BO Universes will support this structure? Thanks.

Querying Nested Tables with Multiple other Tables

I am trying to query columns from a table and it's nested table and do a join to another table.
SELECT IM.*,
IMP.PROGRAM_ID,
S.STAGE_NAME
FROM TB_ITEM_MASTER IM , TABLE(TB_ITEM_MASTER.PROGRAMS) IMP, TB_STAGE S
WHERE S.STAGE_ID = IM.STAGE_ID
AND IM.PROGRAM_ID IN(1,2);
When running this query I receive the error:
ORA-00904:"TB_ITEM_MASTER"."PROGRAMS": Invalid Identifier
I actually copied this query straight from an Oracle Documentation, just replaced my table names with theirs. This query will almost be like a template to me as the program_id field in the Nested table is very cruicial to me. I will joining many tables to TB_ITEM_MASTER and using the where clause against program_id. What's the problem here?
Please advise.
ps. Did I mention how much I hate working with this Nested table stuff:(

You must use the alias name, not the table name.

Capturing a nested "Section" hierarchy with a Conversion Table?

(Frame 9) - I'm using a Conversion Table to convert a client's unstructured documents to structured. Much of the structure is importing with a certain amount of success, but I can't figure out how to capture the nested hierarchy. The client's template uses the same "Section" element with a "Title" child element for each level of the document.
I can capture the document headings from the H1, H2, H3 paragraph tags form the old document and wrap them in "Title" elements with H1, H2, H3 qualifiers but I can't figure out how to then wrap the Title elements in the corresponding Section elements that reflect the hierarchy levels. Frame must have an internal qualifier for the Section elements but I can't figure out how to look it up?
Thanks, Chris

Chris,
It should work fine if you have the qualifiers properly specified in the rules for wrapping the sections. Here is a link to a working sample that shows how it is done, which coincidentally also uses Section elements (but Heading elements in place of Title elements):

How can i create Level Based Hierarchy using multiple logical table.

Hi All,
in my use case i have two master logical table.
Division_Mst(divncd,DivnName)
Department_Mst(deptcd,DeptName)
and one logical table which contain both column Header (divncd,deptcd)
and fact table detail where one measure column(empcd) using aggregation count on it.
so i want to create levelbased hierarchy like this.
DivnName
|------DeptName
which are come from(Division_Mst,Department_Mst) .
so user can see no of employees division wise and drill down to Department wise.
How can i achieved this?
thanks

Unable to Open Document With Multiple Sheets & Tables

Hi,
Since I've had Numbers for iOS I've been a little disappointed that Apple forgot the complexity of spreadsheets.
The reason I say this is because i've been trauling for my latest problem for quite a while.
At the moment on my MBPro, I have a Numbers document saved in iCloud which works PERFECTLY for me (on the MBP).
It consists of about 5 sheets, each having 2 tables.
Each of those tables has 3 or 4 forumals which relate to relative cells. They're nothing but basic arithmatic cells i.e. think of a journal sheet for a business. Works in the same fashion but tracks my mortgage payments etc...
It opens perfectly on my Mac, but when I fire it up on numbers, I get a crash and a crashlog.
Before I flummux everyone with the crashlog, has anyone experienced this yet? If not and you need the crashlog, I can post it. From what I see, it's a non-specific error which I can't seem to decypher.
Any help would be appreciated!
Cheers,
Adrian!

Just to cofirm that this has been solved by the iWork team. THemselves. Below is the message which I received back with the file I send them with the appropriate corrections:
Hello,
In Numbers on iOS, the restrictive formula editing is not handling the extra space in some of the formulas. In some of the tables, in column D, the formulas have a space between the function name and the open parenthesis.
E.g. =IF (...
Attaching a file with the extra spaces removed that should open on your iPhone.
This issue is noted.
We appreciate your time.
The iWork Team
I think this boiled down to a bug. I wouldn't have ever thought that the creators of Cocoa would even let a bug like this slip through
Ace work for them spotting this though!

Enqueue with multiple secondary tables

I have an enqueue object that locks one primary table and several related secondary tables. When I call the FM using the key of the primary table I notice that I cannot open any secondary table record in change mode in an alternative transaction. It's as if each secondary table has been entirely locked.
I was expecting that only those records in any secondary table whose foreign key matches the key of the primary table would be locked.
How do I lock only the set of related records based on the key of the primary table without having to loop at each related secondary table record and locking these in turn? I mean, I know I could do this, but is that really the only way?
How does SAP manage this problem?

Sandra
Ok, so I created the tables and locks from scratch. The only thing I did differently was to run the enqueue FM's via SM37 so I don't have to create 2 new test programs. I am still getting the same results as before.
This is my dummy Table T1 (key = ZF1)
ZF1    |    ZF2    |   ZF3
0001   |    A      |    AA
0002   |    B      |   BB
0003   |    C      |   CC
0004   |    D      |   DD
0005   |    E       |   EE
This is my dummy Table T2 (key = ZF4 + ZF1; FK = ZF1)
ZF4     |   ZF1      |    ZF5
2001    |   0001    |     AA
2002    |   0001    |     AB
2003   |    0002    |     AC
2004    |   0001    |     AD
2005    |   0003    |     AE
2006    |   0004    |     AF
2006    |   0005    |     AG
2007    |   0005    |     AH
There are also 2 enqueue FM's. E1 locks T1 & T2; E2 locks only T2. When I execute E1 where T1-ZF1 = 0001 I expect that the foreign key relationship in T2 would mean I also lock T2 where ZF4 = 2001, 2002 and 2004. Yet for example, when I execute E2 with T2-ZF4 = 2007 in another session this triggers a lock conflict.
The only way I can request a successful lock on T2 when I have already called E1 is to fully qualify all of the E2 FM parameters. For example, if I call the E2 where T2-ZF4 = 2007 and T2-ZF1 = 0005 then the request is Ok.

Nexus 5548UP VFC with multiple physical interfaces

I have a physical host that is evenly quad-homed to a pair of 2248PQ Fex's. Each NIC interface is 10Gb.
Each of my fex's is single homed to a 5548UP in a VPC configuration. I am using FCoE and I have CNA's in my host. My design is below.
On the LAN side, I would like to have a full 40Gb LACP / VPC Port channel. On the FC side, I would like to be able to create a VFC on each side, (or multiple VFC's if that is required), and attach it to both interfaces on each side, so that I have two full FC paths from the host to each SAN fabric, also for a total of 40Gb.
I've seen some Cisco diagrams in some much older forum posts that show that this is not possible, but I've seen nothing recent on this. Does anyone know if it's possible?

Hi,
If you have two different storage separated, then how this would be possible since in that condition you need to allow both storage on same Port-channels which I think is not valid design.
Have you got any answer or solution for this ?

Ajay

Working with large database with multiple large tables ( orcale 11)

Hi all,
I'm trying to read and parse 3 tables:
NetworkEvent - 500000 entries
NewTrapEvent - 500000 entries
NewTrapVlaue - 2000000 entries
I I used 1 JDBC connection, 2 statements and 3 ResultSet( i used same statement for two queries).
My questions are:
==========
1. Is it reasonable? or should I add more connections? or more statements?
2. Additionally when creating the Result Set I used the following parameters:
ResultSet.TYPE_SCROLL_INSENSITIVE
ResultSet.CONCUR_READ_ONLY
and stmt.setFetchSize(1000)
is it valid parameters? should the fetch be larger?
is there any more important parameters that I missed?
3. When setting the SQL command, I used each command to retrieve all the table entries:
"select * from ana37.NetworkEvent order by detectiontime"
Should I take partial entries in a loop? (for example 100000 in each loop) or is it ok for the Result Set to hold all of the entries( 2 milion)
4. Can I clean the result set when I finished processing previous entries?
thx
Edited by: user9001513 on 06:59 23/11/2010

Why don't you use a stored proc?
Why are you ordering it?
Should I take partial entries in a loop? Yep. Because software isn't perfect. No point in attempting to process the universe when you know it will fail sometime and it is easier to handle smaller failures than large ones (and you won't have to redo everything.)
