OLAP cube - complex join condition

• Join condition of cube and other mapping missing mapping

  Hi David,
  
  I have a strange problem... After the creation of cube mapping tables defning and physical objects joins and the change of my mapping intermittently disappears... Not being able to trace what's happening. Is this a known bug or nothing is done correctly?
  
  Enjoy your previous answer.
  
  Thank you very much
  Paiva

  A "mapping" is a term of olap product management which means that the cube is not mapped to the level the fact sheet. For example, suppose you have tables like this

  CREATE TABLE SALES_FACT
  (
    DAY_OF_SALE DATE,
    PRODUCT_ID NUMBER,
    UNITS NUMBER,
    COST NUMBER
  )
  
  CREATE TABLE TIME
  (
    DAY DATE,
    MONTH NUMBER,
    QUARTER NUMBER,
    YEAR NUMBER
  )
  

  Suppose you want to analyze the data only at the level of the MONTH and more. In this case, you must set a time of hierarchy which includes levels MONTHS->->-> ALL_TIME YEAR QUARTER and you would need to define a join condition between SALES_FACT and TIME of the form

  SALES_FACT.DAY_OF_SALE = TIME.DAY
  

  This is sometimes called a "mapping" because it maps data in the AW to a higher level than what is stored in the fact (for example, the MONTHS instead of DAYS).

• Join physical & complex join

  Hello
  
  I'm little confusion when join physical use and join complex. Can we create a complex join in physical layer? If so, when it is used? and can we use physical join in layer MDB? If so when should I use? Can you please give me some examples.

  can we use physical join in layer MDB?

  You can also use physical joins in MDB to override the join in the physical layer, but only under very specific conditions.

• Windows 7 - Excel 2010 - unable to connect to the OLAP Cubes SQL 2000

  Running 32-bit Windows 7 - Excel 2010 - unable to connect to SQL 2000 of the GreatPlains OLAP Cubes - message Getting connection refused actively.

  It works with XP and even load Excel 2010.  I can't find what I need to change in win 7.  I guess that's the firewall or driver settings.  I completely disabled the firewall and still no luck.  I also took the file to connect to the XP machine and tried to use it as an existing connection and still have the error.  I ran Excel on the Win 7 XP SP2, XP SP3 and still no luck.  I have spent hours reading and researching the issue and can not find an answer.
  I tried to change the OLAP service account and open all ports on the server.  Still nothing.  The error message will connect to the client computer and the server does not record demand, so I think that I don't yet get on the server.  I do not understand as well as if the message is actively refusing connection.
  I can run the cubes very well on the server and on the XP SP3 with Excel 2010 machine.
  I'm in my troubleshooting garnis.  There has been some problems, that I have not been able to solve in Microsoft Servers and this is one.  I know that there is an answer.  I'm just not see it.
  Thank you!!

• Confused about the complex joins in joins Manager

  Hello
  
  I know that when we create join in the physical layer, we must use "foreign key" this icon,.
  
  and when we need create joins in the MDB layer, you need to use 'new joint complex. "
  
  so, what is the purpose of the complex joined in the Manager of joins? I'm so confused on this subject...
  
  Kind regards
  Anne

  Hello
  Please see the below a

  http://obiee11gqna.blogspot.com/2011/02/interview-questions-on-joins-in-OBIEE.html

  ---> complex join is that join in join where as two tables has no way join foreign at this complex time key is used

  --> Join complex:-join complex are used in the physical layer between two tables where ever who do not key primary and forgin key relationship.

  Foregin Key:-using the forgin key we can define the join between two tables. joins between is 1:M or M:M., if we want to define: many relationships we use the bridge tables.

• Complex join, problems

  Hi guys!
  
  There is a select statement
  

  WITH t AS (
       SELECT 1 ID FROM dual)
       , t2 AS (
       SELECT 1 ID, 1 acc1 FROM dual UNION ALL
       SELECT 1 ID, 2 FROM dual)     
       , t3 AS (
       SELECT 1 ID, 1 acc2 FROM dual UNION ALL
       SELECT 1 ID, 2 FROM dual UNION ALL
       SELECT 1 ID, 3 FROM dual)          
  SELECT t.ID,
    t2.acc1,
    t3.acc2 
  FROM t, t2, t3
  WHERE t.ID = t2.ID
    AND t.ID = t3.ID     

  the result of this statement:
  

  id    acc1     acc2
  1     1     1
  1     1     2
  1     1     3
  1     2     1
  1     2     2
  1     2     3

  but I want to get this result:
  

  id    acc1     acc2
  1     1     1
  1     2     2
  1     null     3

  How could I achieve this?
  
  Thank you!

  Hi, Pavel,

  Pavel E. says:
  Ok. We will explain on the other hand:

  Please do not explain. Give more examples is good, but it is not the same thing to explain.

  ... Table t is 'main' (Board), tables t2 and t3 - charts of accounts. And I'm still a link t2 and t3 to t. This is why I want to get this result:

  id       acc1       acc2
  ------  -------   ------
  1     1         5
  1     2         6
  1     null         7
  2     3         9
  2       null        10
  3     4           11
  

  Sorry, I don't see why you want the results of these data.

  Why is that not the correct results?

  id       acc1       acc2
  ------  -------   ------
  1     1         6
  1     2         5
  1     null         7
  2     3         9
  2       null        10
  3     4           11
  

  Do you want
  the lowest acc1 joined the acc2 lowest (for the same id).
  the 2nd lowest acc1 joined the 2nd lowest acct
  ...
  the nth lowest acc1 joined the lowest acc2 n - th?
  If so, then you want what I call a Fixed price request . The ROW_NUMBER analytic function allows to assign numbers 1, 2, 3,... for t2 and t3 lines, depends on the question whether this line is the 1st, 2nd, 3rd,... value of CAC more down for each ID use this number (and not on the value brute accc) in the join condition.
  If sometimes niot t2 will have a row of mtching to t3 (but you want to include in any case) and at other times t3 will not have a row in t2 (but you still want to include it) then make the join, outer join full.

• First time to create the OLAP Cube - problem of aggregation

  I'm new to OLAP technology and I want to build the first OLAP cube. I use the scott schema is:
  
  1-building dimension on the table 'DEPT' with a level deptno.
  
  2-building cube with a sal of measure on the table 'EMP '.
  
  
  Emp table
  
  DEPTNO SAL
  
  20 800
  30 1600
  30 1250
  20 2975
  30 1250
  30 2850
  2450 10
  20 3000
  10 5000
  30-1500
  20 1100
  30 950
  20 3000
  10 1300
  
  
  DEPt table
  
  DEPTNO DNAME
  
  10 ACCOUNTING
  SEARCH 20
  30 SALES
  40 OPERATIONS
  
  
  
  When I use the wizard to maintain and then display the data, that the sum of the wage is not accurate, it looks like
  
  sum
  
  all departments 5550
  accounting of 1300
  Researches. 3000
  sale 1250
  0 operations
  
  
  the values must be
  
  sum
  
  all departments 29025
  accounting 8750
  Researches. 10875
  sale 9400
  0 operations
  
  Why the aggregation of the values for the ministries are not accurate?

  Problem is visible in your table.

  Emp table

  DEPTNO SAL

  20 800
  30 1600
  30 1250
  20 2975
  30 1250
  30 2850
  2450 10
  20 3000
  10 5000
  30-1500
  20 1100
  30 950
  20 3000
  10 1300

  There are several Dept. not with different sal. In OLAP when you load this record then the last record just victories. That's why, if you look at it then you will see the value that you see is the last value is charged.

  To solve this, you should do a group (emp) deptno and sum (sal). Load the folders and you'll see the correct result.

  I hope this helps.

• not able to create the logical complex join in the Administration of BI 10.1.3.4.1.

  Hello
  
  I am facing this strange question in the business model. While I am able to create the logic of foreign keys (which, according to the documents, should not be created), for some reason I'm not able to create logical complex joins.
  Actions:
  (1) manage / joined... joined by Manager: Actions / new / logic to join...
  (2) in the window "join logic", I select the tables, BUT I can not choose any column (her are shown in "Column," drank lists these lists seem to be disabled)... .and combo box operator is disabled
  
  Same result when trying to view "Diagram of logical table" and a "new complex joining" from one table to the other drag-and-drop...
  
  Doesn't seem to be something related to this particular business model, because now it happens to all business models I... funny that there are some former complex logic is associated with some of my old business models
  
  Any ideas?
  
  Thank you!

• try to find the join condition

  Hello
  Does anyone know what table in the working repository stores the join interface conditions?
  
  
  
  Thanks in advance
  REDA

  Raj,

  You can reach SNP_TXT, SNP_POP_CLAUSE and SNP_POP for the join conditions.

  Select sp.pop_name, snp_pop sp, spc snp_pop_clause st snp_txt st.txt
  where SP. I_POP = SPC. I_POP
  and MS. POP_NAME = "YOUR_INTERFACE_NAME".
  and SPC. I_TXT_SQL = ST. I_TXT

  See if that helps you.

• Problem definition complex join in the physical layer

  I have a problem with the definition of a complex join in the physical layer.
  
  I have the following two tables:
  
  DIM_ORG
  Id_Org
  DT_Start
  DT_End
  Nom_org
  
  FACT_REV
  Id_org
  Recipes
  
  The tabel DIM_ORG is type 2 SCD. The current/active nom_org can be identified in the table because DT_End will be empty.
  
  Using the expression builder to configure the physical join I have entered the following expression:
  
  DIM_ORG. Id_Org = FACT_REV. Id_Org AND DIM_ORG. DT_End is null
  
  The expression builder accepts the syntax, but when I want to close the physical foreign key window I get the message:
  
  [nQSError: 30001] Only the columns, designated operators and predicates are allowed.
  
  Any suggestions how to solve this problem? Am just missing something? All I want to do is set up a join to pick up the active nom_org of my size.
  
  Thanks for your help!

  Make a foreign key in the physical layer:
  DIM_ORG. Id_Org = FACT_REV. Id_Org

  In the MDB, set the logical table org dim source/content in tab/where a part:
  DIM_ORG. DT_End is null

• Join does not work for NULL values on the join condition

  Hello

  So now if I include a join condition more where null = null situation arises, it's working now.
  Just tell her not to treat (1 and null) (1 and null) are the same.
  What is the solution. This is an expected behavior.

  Pramod salvation,

  Another way to use the outer join is,

  Select f.x, f.y, s.b
  of a, f, s b
  where f.x = s.b (+)
  and nvl(f.y,0) = nvl (s.y (+), 0);

  Hope this will help you.

• Error when you try to validate the Join Condition

  In a map, I include a Carpenter and set the join condition. By clicking on the button post, I got the following error: "an error occurred during validation of the expression. Bad expression return type. »
  
  At first, we thought it was a problem when you create a new map. However, we returned to the existing mappings already validated successfully and each join now returns this error OWB. This occurs for each installed user with OWB. Mapping validate successfully in the end, but the join itself will not be validated during development.
  
  We currently use customer 10.2.0.4.36 OWB and OWB 10.2.0.4.0 repository. The latest patch is causing this problem? A way to solve this problem?
