Can we Join 2 fact tables ?

Hi All,
We are trying to join 2 fact tables using a logical dimension. Let me explain my structure fact1 dim1 and fact2 dim2 another dim dim3 which is joined to Fact1. Other dim contains only columns for joining fact1 and fact2.
When I pick columns from fact1 and dim3,dim1,dim2 it works good. Either Fact2,dim1,dim2,dim3 works good but does not wrok when using columns for both fact1 and fact2.
Here we are using couple of materialized views both on Oracle Apps tables and some Custom tables.
Can any one have some kind of solution when using multiple fact tables.
Thanks,

Yo can join as the same joins mentioned as per your physical joins.
But you need to set dimensions hierarchy & aggregation level in BMM layer for sure.
In Reports set the aggregation rule to complex server level.

Join fact table with higher dimension level

how do i join fact tables with higher dimension levels with discoverer?
fact with detail at level C
measure X
dimension with
D->C->B->A
E->C
level
A B C
1------1------1
2------2------1
3------2------1
join between fact X and dimension level C
X=3*C because of sum(X) in discoverer and 3xC in dimension
is there a way to get correct values for X without creating a dimension like
D->C
E->

another way of asking this is whether you can create a summary table in Discoverer at a higher level than a dimension's fundamental grain. In other words - the summary examples in the documentation all describe leaving out one or more of your dimensions... they are either left in or completely taken out. But, some of the most effective summarization occurs when you summarize daily data to a monthly level. Assuming that I have a sales table (at a daily level, and a key value sales_date), and a table date_dim (primary key sales_date), I would like to create a summary sales_month_summary where the sales are grouped on month_year (which is a field in the sales_date table).
How is this done? I suspect that we can't use the date_dim table with the summary (due to the problems noted by the poster above). Do we have to create another table "month_dim"? Do we have to fold all of the desired date attributes (month, quarter, year) into the summary? Obviously we'd like to re-use all of the pertinent already existing date items (quarter, month, year, etc.), not recreate them over again, which would result in essentially two sets of items in the EUL. [One used for this month summary, and another used for the detail.]
I searched the forum - someone asked this same question back in 2000 - there was no answer provided.
The only other thought I have is to "snowflake" the date_dim into two tables and two folders, one at a date level, another at the month level. Then the detail tables can connect to date_dim (which is linked to month_dim), while the summary data can connect directly to month_dim.

- From a physical data model point of view, yes.
- From a logical data model point of view, not.
To resume, you can but one of the fact must be in the business model layer of the repository designed as a dimension of the other fact table.

How can I make fact table?

Hi all
I would like to make fact table in oracle 11g using SQL syntax. how can I do so?
Is Analytical Workspace Manager available by defult in oracle 10g or 11g?
Do you recommand good book for implementing star schema or ROLAP? i want the setps and sql syntax examples.
thanks

Hi,
You can make a fact table through any number of ways viz:
- CREATE TABLE syntax , your table design would correspond to the dimensional model (Star Schema / Snowflake Schema) specifications
- You can alternately use an ETL Tool like OWB to design your star schema
As far as I know i dont think Analytical Workspace Manager comes by default with an Oracle DB Installation
- Read any book you find on Dimensional Modeling to get a hang on building Star Schemas and OLAP Concepts. You would definitely find one such book in "The Oracle documentation library"

Join fact tables with different grain without upsetting measures?

Say I am a business analyst at a university, and I have two analytical cubes available to me: an Enrollment Cube and an Admissions Cube. The Enrollment Cube has a grain of Student and Semester, whereas the Admission Cube has a grain of Student, Application and Semester (a potential student can have more than one application in a semester). Is there any way for the OLAP developer that makes these cubes to make it so that I can use both cubes' fact tables without messing up their corresponding measures, such that I can create such analyses as the following:
County
Semester
Acceptance Rate (Admission Fact)
Retention Rate (Enrollment Fact)
County A
1
30%
88%
2
60%
87%
3
42%
84%
County B
1
90%
100%

One suggestion is to create a view that joins the 2 fact tables and then create a cube with measures mapped to the view for analysis purposes. However, this would be using the measures of the new cube for the analysis.

Joining Fact tables

Hi,
In what cases can two fact tables be joined.
Can anyone explain why there is a join between promotion facts and shop facts in efashion database and that too shortcut join.
Please put some comments.
Ganesh

It shouldn't be imho. I think it's incorrect and is a result of bad analysis leading to bad table design. I went on a course years ago where we discussed this and said that you *might* consider making that a full join and creating a context with only that one join in it if you have denormalised dimensions in one of the facts but not the other. However, you'd only do that if you were certain of the granularity of the join. We agreed, though, that the model was principally flawed and it would be a lot less painful to reassess the model and rework it.

Can we join fact to fact?

i am new to obiee i found this question in some bi sites.
” If you have 3 facts and 4 dimension and you need to join would you recommend joining fact with fact? If no than what is the option? Why you won’t join fact to fact?
i found the answer like this
o In the BMM layer, create one logical table (fact) and add the 3 fact table as logical table source.
but i didn't find the anser for Why you won’t join fact to fact?
Pleae guys help me.......................
Thans in advance.
Rani

You can join any two table which has some relationship but ideally you don't join Fact to Fact because its not a good practice and degrades performance..

Can we join 3 tables with left outer join

hi friends.
 Can any one tell how to join 3 tables using left outer join...i tried by taking some fields of ekko,ekpo,eket, but this not working ... plz give a sample code with some fields.

Hi Uday
Inner joins using 3 tables 
Try this :-
SELECT stpo~stlnr stpo~idnrk mast~matnr mara~mtart stpo~menge
INTO CORRESPONDING FIELDS OF TABLE zmat1 FROM mast
JOIN stpo ON stpo~stlnr = mast~stlnr
JOIN mara ON mara~matnr = mast~matnr
WHERE stpo~stlty = 'M' "AND stpo~idnrk IN s_matnr
AND mast~werks = 1000.
Here s_matnr is a select-options on the selection-screen. 
Or this. 
Code: 
 Select single Vbrk~Bukrs Vbrk~Kunrg Vbrk~Vbeln
 Vbrk~Fkdat Vbrk~Bstnk_Vf Vbrk~Zterm
 Tvzbt~Vtext
 Vbak~Vbeln Vbak~Bstdk
 Likp~Vbeln Likp~lfdat Likp~Lfuhr
 into w_vbrk
 from vbrk
 inner join Tvzbt on Tvzbt~Zterm = Vbrk~Zterm and
 Tvzbt~Spras = sy-langu
 Inner join Vbfa as SalesLnk
 on SalesLnk~vbeln = pu_vbeln and
 SalesLnk~vbtyp_v = c_order
 inner join Vbak on Vbak~Vbeln = SalesLnk~Vbelv
 Inner join Vbfa as DeliveryLnk
 on DeliveryLnk~vbeln = pu_vbeln and
 DeliveryLnk~vbtyp_v = c_Delivery
 inner join Likp on Likp~Vbeln = DeliveryLnk~Vbelv
 where vbrk~vbeln = pu_Vbeln.
This code locates sales, delivery and payment terms info from a billing document number.
or

Here, this one also works fine :
select zfpcd~cadivi zfpcd~proforma zfpcd~factura zfpcd~aniofactura
zfpcd~montousd zfpcd~montoap zfpcd~ebeln zfpcd~inco1
zfpcd~lifnr lfa1~name1 zcdvs~status zfpcd~conint
into it_lista
from zfpcd inner join zcdvs
on zfpcd~ebeln = zcdvs~ebeln
and zfpcd~proforma = zcdvs~proforma
and zfpcd~lifnr = zcdvs~lifnr
inner join lfa1
on zfpcd~lifnr = lfa1~lifnr
where zcdvs~status = '04'.

How can I join 3 tables while extracting data from SAP R/3?

I have 3 tables with the following columns
Emp table (emp)
emp_id
emp_name
emp_add
Dept table (dept)
dept_id
dept_name
dept_loc
Location table (loc)
loc_id
loc_name
Now. If I want to select data from loc_id = 10 and emp_id between 2000 and 3000
How to join these three tables while extracting data from R/3
join condition
loc.loc_id = dept.loc_id
and dept.dept_id = emp.dept_id
and loc.loc_id =10
and emp.emp_id between 2000 and 3000.
Could any one let me know the procedure to extract this data into BW system.

Hi,
shouldn't your join condition be:
loc.loc_id = dept.DEPT_LOC
and dept.dept_id = ??
If you can join the three tables then create a generic datasource (RSO) based on a view (create your view with your join in SE11).
Enable the loc_id and the emp_id as selectable in the datasource so you can then select the values from a BW IPack.
hope this helps...

Can I join two tables from two different dbs by using transparent gateway?

E.g.:
select * from t1@rdb1, t1@rdb2
Can this work?

As previously stated you options depend on your Oracle version and platform and the target version and platform for the remote non-Oracle (well in this case mySQL) database.
Oracle replaced HS or Generic Connectiivy with a new name and support module on 11g and maybe in 10g. You can see your manual CD or check the online documentation.
For that matter you need to check to see if the Transparent Gateway product has a mySQL driver.
The following Oracle support articles may be of interest.

OBI Joining two lookup tables. [nQSError: 14025] No fact table exists at the requested level of detail

Hello,
I basically have only fact tables that I need for my analysis. No dimensions, no hierarchies.
When add two tables in OBI Answers to start the analysis I see this error:
[nQSError: 14025] No fact table exists at the requested level of detail
I have them defined as lookup tables. How can I join lookup tables?
In order to pre-filter them using the user_name session variable.

Hi Nagireddy.
As described:
open your rpd. go to "manage" -> Variable Manager / New / Session / Variable. so to create a new session variable in the .rpd.
then you create a variable NO_FORCE_TO_DETAIL_BIN and se the default to 1.
BUT....this did actually not do the trick
I have created a logical table that is a table made up of the two that I just want to join and as soon as I create a bi answers report that contain columns from those two tables I see the error 14025.

How to create logical fact table in BMM layer ?

Hello,
I have 3 Dimension table - 2 are in one schema and last is another schema. Using this 3 dimension tables, I need to create a logical fact table.
So, my question is whether we can create this fact table by joining these 3 dimension table which are in 2 different schema s ?
Thanks

Fiaz,
you are correct. We can use tables from different subject area to create a report. However, my question was related to rpd design. Sorry, I was not very clear about the queries earlier.
Here is the whole scenario in the physical layer of the rpd
Table name      Databse name      Connection pool name      Schema name
AV          AV_PXRPAM     AVAILABILITY          CRMODDEV
OUTAGE          AV_PXRPAM     AVAILABILITY          CRMODDEV
COMPANY          PXRPAM          PXRPAM_POOL          CRMODDEV
AV and OUTAGE have the joins already. I want to make a join between COMPANY with OUTAGE. And then I want to include a column from each of above tables to the logical fact table in the BMM layer. then I want to do a star schema with the logical fact table to the above 3 tables in the BMM layer.
Thanks
