How to fetch data from multiple fact tables from a normalized schema?

Hello everybody,
I am working on a normalized schema to build my repository. I have categorized the tables into dimensions and facts. I have 3 fact tables in my schema and they have a 1:m:1 relationship i.e. if I have table A, B, and C; A has 1:m relationship with B and C also has 1:m relationship with B. How can I use measures from these tables to create a star schema. If A = Sales, B = Transaction, C = Payment_Amount
Sales(Sales ID, Amount, Tax pct, ...)
Transaction(Transaction ID, Sales ID, Payment ID,Transaction Amt, ...)
Payment_Amount(Payment ID, Check ID, Payment Made, ...)
Please give me some direction to pursue.
Thank you!
D

Hi dcole,
Go through this link for snowflake schema http://gerardnico.com/wiki/datamodeling/snowflake_
http://www.rittmanmead.com/2007/06/19/obiee-data-modeling-tips-1-integrating-1-1-and-1-many-source-tables/
I suppose it should work with snowflake schema...Im interested in this topic please let me know what is your approach every now and then.

Multiple fact tables in Essbase studio schema

Hi all,
Can we pull data from multiple fact tables in the single schema using essbase studio ? Also is it advisable ?
Please advice.
Thanks
Andy

Hi Glenn,
Thanks for the prompt reply.
Do you mean direct joins between fact tables ? or we can have indirect joins through Dimension tables ?
Thanks,
Andy

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

How to display a description in fact table from an unrelated DIM table in powerpivot?

Hello,
I have two tables in powerpivot 2010: 1 that is my fact and the is unrelated. I'm relatively new to SQL and powerpivot.
What I need to do is display a description from my DIM table based on a column in my fact. Is this possible? In my fact, I
have a ReasonID, the DIM has the ReasonID and description. I just need the description added in my fact as a new /
another column. Thanks. John

Hello,
When you have the same column in both tables, then they are related, even if in database no primary / foreign key is defined. In PowerPivot we can define additional / manual relation, just Change to "Diagram View" and define the relation like below:
But if you still want the "Dim description" as a computed column in your fact table, then you can use the
LOOKUPVALUE function
=LOOKUPVALUE(Dim01[Description], Dim01[ReasonId], Fact01[ReasonId])

How to view data on E fact Table?

Hi Experts,
I am trying to view the contents on a E-Fact table (/BIC/E<Infocube Name>), what I tried so far show 0 entries since data have beed compressed. I tried SE16 for example, Listschema, RSCUBE....
Any Input Please?

Hi
Can u tell me hwo many records are there before compression ?
Go to se11--->/bic/e<ic name> ->no. of entries.
I think the u did not perform compression step . once check the data in the f fact table.
Thanx & Regards,

Field-Symbols: How to retrieve data into an internal table from FS

Hello All,
I am working on field symbols.I have declared the field symbols as shown.
FIELD-SYMBOLS: <gt_pos_data> TYPE table,
                           <wa_pos_data> like <gt_pos_data>.
Data: Begin of itab occurs 0,
           field1(5) type c,
           field2(10)_type c,
         end of itab.
The FS <gt_pos_data> has 100 fields but I need to move only two fields from this FS to my internal table itab.I am doing the following.
loop at <gt_pos_data> assigning <wa_pos_data>.
itab-field1 = <wa_pos_data>-field1.
itab-field2 = <wa_pos_data>-field2.
append itab.
clear itab.
endloop.
But it is giving me an error saying "<wa_pos_data> is a table without header line and therefore has no componet FIELD1".How to achieve this requirement?
Thanks in advance
Sandeep

<wa_pos_data> should be defined LIKE LINE OF <gt_pos_data>, but it will still have no structure, so you need to assign a field symbol to the component as well.
FIELD-SYMBOLS: <gt_pos_data> TYPE table,
                           <wa_pos_data> like LINE OF <gt_pos_data>,
                           <field> type any.
Data: Begin of itab occurs 0,
field1(5) type c,
field2(10)_type c,
end of itab.
loop at <gt_pos_data> assigning <wa_pos_data>.
assign componet 'FIELD1' of structure <wa_pos_data> to <field>.
if sy-subrc = 0.
itab-field1 = <field>.
endif.
assign componet 'FIELD2' of structure <wa_pos_data> to <field>.
if sy-subrc = 0.
itab-field2 = <field>.
endif.
append itab.
clear itab.
endloop.

How to insert data into custom database table from an hcsf

i want to insert data into database table that i have created from an hcsf.
example :
say i have created a table in oracle database and i hav created a hcsf file.now i want that when somebody fills in that hcsf and click submit ,i want that entries should be updated in my database table.
plzzz reply ASAP(it's urgent)

you'll need a bit of Java code... extract the data during a check-in filter, and insert it into the database.
check out the "DataAccess" component in the HowToComponents for query-running examples, and the "DynamicPrefix" component for a check-in filter example.
I have older copies here:

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.

OBIEE report from multiple facts at different levels

Currently we need to develop a report with columns from 3 different facts surrounded with conformed and non conformed dimensions at different levels.
After setting the hierarchial levels and putting the facts into single logical table with different sources OBIEE is generating 2 different queries and does a full outer join.
I would like to know how we can do a left outer join instead of full outer join between the 2 queries based on a common column?
Thanks in advance.

Hi Vinod,
The scenario provided in the link above doesnt match to my issue.
We need to develop a report from multiple fact tables at different levels with conformed & non conformed dimension columns.
I have 7 dimensions D1, D2, D3, D4, D5, D6 and D7 & two fact F1 and F2 tables.
F1 is tied to dimensions D1,D2,D3,D4,d5
F2 is tied to dimensions D3,D4,D5, D6 and D7.
In my report I have columns from D1, D2, D3, D4, D5, D6, D7, F1 and F2.
So OBIEE generates 2 queries with columns from D1,D2,D3,D4,d5 & F1 measure and another query with D3,D4,D5, D6, D7 and F2 measure.
and then does a cross fact join out of box between 2 queries.
But I need to do a left outer join between the 2 queries on a common column instead of cross fact join. I would like to know how we can achive this.
Thanks.

Filters on non-conforming dimensions when fetching data from multiple facts

Hi,
I would like to confirm my understanding about how OBI fetches data from multiple facts. I have set up the BMM layer. Through Answers I am getting data from multiple facts as expected. However, is it necessary to base filters only on the conforming dimensions? If I do so, I am getting the correct data. But if I filter data on non-conforming dimensions, then I am getting more data which I am not expecting.
Suppose, Fact1, Fact2 and Fact3 share a CommonDim dimension. If I have a filter on CommonDim, then the filter is used on the three fact tables. However, if I filter data based on Fact1's DimTwo which is not shared by Fact2 and Fact3 and I have measurements from all the fact tables, then from the SQL generated, it seems that OBI is fecting all data from Fact2 and Fact3 and data from Fact1 where DimTwo = 'SomeValue'. Then it seems to be merging the data from the three result sets.
Is this expected, esp. a scenario where a filter is based on a non-conforming dimension (DimTwo in the example)? Have I missed anything? What do I need to do, if I want to return rows from Fact1 based on DimTwo's filter and then if there is data on Fact2 and Fact3 based on the value in CommonDim corresponding to DimTwo's filter?
Please let me know.
Thanks and regards,
Manoj.
PS.: I have got a link now which is http://obibb.wordpress.com/2010/06/06/multiple-fact-reporting-on-non-conforming-dimensions-part-ii/
Edited by: mandix on 25-Oct-2011 12:01

Hi
The problem you describe is similar to mine (I wrote several threads ago).
That is, if there is a non-conformed dimension in a report then the column from the fact table which is not connected with those non-conformed dimensions containes zeros or blanks.
Was this problem solved? I didn't quite catch one of previuos messages... If you can please repeat it more detailed.
What I tried to do is to set Total level in the Content tab (LTS properties). In this example - I could set Total level to JOBS in the plan type dimension. But it didn't help.
So if you know what to do then please describe it here...

To fetch Data from multiple database tables!

How to fetch Data from fields of multiple database tables!
Give me one example!

use <b>join....</b>
c the SAPHELP docs...
FROM tabref1 [INNER] JOIN tabref2 ON cond
Effect
The data is to be selected from transparent database tables and/or views determined by tabref1 and tabref2. tabref1 and tabref2 each have the same form as in variant 1 or are themselves Join expressions. The keyword INNER does not have to be specified. The database tables or views determined by tabref1 and tabref2 must be recognized by the ABAP Dictionary.
In a relational data structure, it is quite normal for data that belongs together to be split up across several tables to help the process of standardization (see relational databases). To regroup this information into a database query, you can link tables using the join command. This formulates conditions for the columns in the tables involved. The inner join contains all combinations of lines from the database table determined by tabref1 with lines from the table determined by tabref2, whose values together meet the logical condition (join condition) specified using ON>cond.
Inner join between table 1 and table 2, where column D in both tables in the join condition is set the same:
Table 1                      Table 2
A
B
C
D

    | a4 | b4 | c4 | 3 | 3 | e2 | f2 | g2 | h2 |

Example
Output a list of all flights from Frankfurt to New York between September 10th and 20th, 2001 that are not sold out:
DATA: DATE   LIKE SFLIGHT-FLDATE,
      CARRID LIKE SFLIGHT-CARRID,
      CONNID LIKE SFLIGHT-CONNID.
SELECT FCARRID FCONNID F~FLDATE
    INTO (CARRID, CONNID, DATE)
    FROM SFLIGHT AS F INNER JOIN SPFLI AS P
           ON FCARRID = PCARRID AND
              FCONNID = PCONNID
    WHERE P~CITYFROM = 'FRANKFURT'
      AND P~CITYTO   = 'NEW YORK'
      AND F~FLDATE BETWEEN '20010910' AND '20010920'
      AND FSEATSOCC < FSEATSMAX.
WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
If there are columns with the same name in both tables, you must distinguish between them by prefixing the field descriptor with the table name or a table alias.

How can we delete the data in e-fact table.

how can we delete the data in e-fact table.

hii,
You cannot delete the request individually but you can one of the following:
1. Do a selective deletion from the cube. RSA1 -> Cube -> Contents -> selective deletion.
2. Delete all the data in the cube and then reconstruct only the required request ids. This would work only if you have the PSA available for all the requests.
3. Reverse posting is another possibility.
hope it helps,
