Fact table/Cube mapping

I'm relativly new to the OWB but I'm in the learing proces...I have some serious problems mapping the cube.
How do I map my surrogate dimension key into the cube (which has the same surrogate key)?
Do I have to map them at all or are they automatically mapped during the creation of the constraints within the cube?
If anybody could help me (or recommend a source/book where to look), this is much appreciated.
Thanks in advance,
Manuel

Igor,
thanks for your reply and your help.
Just to clarify: I created a two dimensions, mapped and executed them (data was successfully loaded!) and finally I created a cube which is linked to the dimensions through the foreign keys (as you described)...
Now I want to load a calculated measurement (which i get through the aggregation operator from one dimension) into the cube and in the same mapping map the surrogate key of the other dimension with the (dimension) foreign key of the cube. But when I try this then I directly get an error in the mapping editor: "API8003: Connection target attribute group is already connected to an incompatible data source".
I'm even not sure if I have to do it like this or if through the foreign key relationship between cube and dimension no direct mapping is necessary! Or if the design is wrong as I have no direct relationship between the measurement and other dimension...
Please help as my thesis is dependend on the data warehouse :-)
Thanks
Mani

Map two fact table

hi,
I have develop one application, in which
1 fact table(cube) and 6 dimension table(dimension)
fact table : project billing detail
dimension table : customer, time, PM, company etc.
its working fine
because there are foreign key in project billing table
now i want to map one project_CR table which is child table of project billing table
i have create one cube for that and in repository i have crate foreign key in business diagram so project_CR table show as a dimesion table
in presentation when i am creating report in BI answer its giving with other dimension table,
its working with only fact table project billing.
how can i map project_CR table so it will work with combination report with other dimension.
please help me..
thanks in advance.

Thanks for your reply.
to the source of dimension table means..?
Should i create new dimension for project_cr ?
one thing i did that i have created one dimension project_id and map both cube project and project_cr with that dimension
now its working fine in presentation layer for project,project_cr,project_id table
but project_cr table now working with other dimension like time,pm.
if i want report with combination of time,project,and project_cr then its showing null data in project_cr.
Please describe me in some detail so i can do it.
Thanks in advance.

OBIEE 10g: Problem on fact table mapping

Hi to everyone,
i have this situation:
1) i have 2 fact tables in phisical model (FHRCTR and HCTOT) this two table is the same in the FK columns.
2) the structure is: FHRCTR[month_fk, transaction_type, measure A], HCTOT[month_fk, measure B]. 'transaction_type' is an attribute of the table not dimension.
3) i have created a logical fact table with this two tables for source.
4) each field of logical table is mapped on the corrispetive field on the both phisical table, except for 'transaction_type' column having as source only FHRCTR table.
5) i've created a report with follow colums: month_fk, transaction_type, measure_A, measure_B
The problem is: if i create the report with the columns in point 5, the measure_B returns null values and the measure_A have a correct value.
Insteed if i create a report without 'transaction_type' column the value of Measure_B and Measure_A are correct.
I remind you that: 'transaction_type' in the logical fact table is mapped only on the FHRCTR table because on HCTOT it doesn't exist.
Can you help me to solve this issue?
Thanks

ThanksI guess when you set some aggregation rule for 'transaction_type' in a repository then all will be ok (for examplу - min). But you'll get results that you don't expect.

Fact table size

Hi Experts
Iam working on implementation project, here already some cube are there is a sales, financials & Material Movements cube.
Here Sales and financial cubes are customer define means start with u2018Zu2019.
Here my doubt is how to know the fact table & cubes size? & how to calculate the fact table &
cube size for customer define and SAP define in our SAP BI 7.0 systems .

Mapping the Fact table to different levels of a dimension

Hi,
I have a fact table which stores the data for 4 levels of the dimensions. The aggregation method was taken care by PL/SQL and the fact table will have the data for all the 4 levels. When im trying to map all the levels to a column in the fact table using the OEM, it is generating the F KEY constraints referncing the columns mapped for the various levels of the dimension.
The problem is that im using a denormalised table for maintaing the values of the dimension. So the columns mapped for the levels(Except for the lowest) can't have the unique key defined on it. The cube is not getting created because of the error in creating the F KEY.
Can u please suggest how to map this fact table.
Thnks,
Manohar Vanama

I am not exactly clear on your schema but I believe you are trying to map tables which are not strict star or snowflake. This means that you cannot use CWM1 (and OEM), unless you change the structure of the tables. You might be able to map the tables with CWM2. The document below will assist you:

How to create a ROLAP Cube that has two fact tables.

I want to know if it is possible to create a ROLAP Cube with two fact tables.
Suppose that I have these two star schemas:
The first star schema has only a measure and a time dimension. The time dimension has three levels (Year -> Month -> Day)
The second star schema has the same measure of the first schema and a time dimension. In this schema the time dimension has only two levels (Year -> Month). The values of the measure of this schema come from the first schema, this is, the value of the measure for a defined year and month results of the sum of all fact values of the first schema, that have the same year and month.
I want to know if is possible to create a ROLAP cube that can get the information of the two star schemas, according to the level that the user are consulting.
For example, if the user consults the cube with "OracleBI Spreadsheet Add-In", and if the user is consulting the first two levels (Year and Month), then the ROLAP cube would get the information of the second star schema.
But if the user does a drill down in a month to get information of the days, then the ROLAP cube would get the information of the first star schema.
Is it possible to do this?
Regards,
Rui Torres

I'm not exactly sure what you want to do. Sorry if I get this wrong.
You have two fact tables, one with data values at the day, month and year levels and a second fact table with data values at just the month and year levels. If this is the case, in the CWM2 APIs or OWB Paris, you would create a view that joins the two tables together and then map this view to the ROLAP cube.
For CWM2 details, please refer to the Oracle OLAP Reference.

Fact table mapping/loading

I am new to OWB and trying to use OWB 9.0.4 to create a star schema on a oracle 9.2 DB. Using OWB client, I successfuly created dims and a fact table on the target DB. But I got stuck with how to use OWB to map the fact table with dims and source tables, and using OWB to generate SQL loading scripts which contains PL/SQL statement shown below:
insert into "fact_table" ("fact_count") ( select count(*) from target_table where dim1='dime_value1' and dim2='dim2_value2');
here dim1 and dim2 are the dims assocated with the fact table and they are also mapped to the corresponding target table columns.

Frank,
source table -> aggregator -> target
As input into the aggregator, you specify dim1, dim2 and any numeric value. If you do not have one, use a numeric constant such as 1. In the aggregator, you specify dim1, dim2 as the group by clause (operator properties). You then add a numeric output attribute (edit function), and go to the attribute properties. As a function, specify count from the numeric input attribute.
That would load your measure.
Cube function is not currently supported in the mapping editor, but you could include that in a materialized view that is based on the table.

FACT table Mapping

I could not find a clear documentation on how to create a mapping to load CUBE
after creating dimensions. I am using 10.1.0.2 version.
I have two dimensions and one FACT table
DIM1
D1_sk
other attributes
DIM2
D2_SK
other attributes
FACT
D1_sk
D2_sk
measure attributes
In previous forums I came across to use a lookup on dimensions
to load the FACT table.
But what would be my source to perform a lookup on Dimensions ?
because My dimensions are the source for the FACT TABLE.
Can I Join the DIMENSIONS to load the FACT TABLE?
can any one suggest the right approach to creat a FACT table mapping.
Thanks in advance.

Hi,
If you can tell what you are tying to achieve we can give some suggestions. You can use the same sources which you have used to load Dimensions, to load Fact table.

How to create solved fact table and corresponding cube

Hello,
I want to create cube with solved fact table. It means, i need to feed data for higher levels of dimension also from fact table instead of aggreting from base level.
I am using star schema and AWM 10g R2 for creating cube.
If anyone knows how to do this, i would be very benificial.
Thanks

All CWM2 validation API shows that my all dims, cubes are valid but when I try to create presentation thru JDev it hangs after selecting Parent-Child Measure.
Any complete working exapmle will be helpful.
P.S. One more query I have can we have one solved and one un-solved dim in the same cube/measure?

AWM adding very less rows in cube as compared to source fact table

AWM is adding just 4 lack rows in the cube. While there are above 10 billion rows in fact table. Even I have applied no aggregation rule at any dimension in cube. And number of rejected records is zero.I am confused what could be the possible reason

Take a look at the SQL query generated by OLAP during cube load.
You can look at it in AWM cube mapping, OR in the CUBE_BUILD_LOG table.
Maybe a SUM..GROUP BY ... is happening during cube load and that is why 1 billion rows are becoming 400,000 rows.
Are the numbers correct when you look at the data at top nodes?

Can't load data to cubes - same error for all DTPs "exception in substep write to fact table"

Hi Experts,
This initial DTP error is:
Data package processing terminated Message no. RSBK229
Error while updating to target <cubename> (type INFOCUBE) Message no. RSBK241
If I drill down to the specific package in the process monitor the error is: "exception in substep write to fact table" .
No more details for why the error is being generated.
SAP BW 307 service pack 8.
I have run the debugger without success, an ABAPer also ran debug mode to get more details on the error without success
We checked teh termination point and the ABAP stack
No error stack is available
No short dumps
I have reactivated the DTP
The data looks fine
The server crashed the day before the DTPs started to fail
One cube is standard content and the other is a Z version of the same cube.
Please let me know if anyone has resolved this issue before and what steps were necessary.

Hello Russell,
We have got the similar situation and we later found that it was a data issue only.
We tried to enable the error stack, but as the data issue was due to a lookup which is bringing the invalid data, its not captured in the error stack and throwing short dump with the message u mentioned.
so my suggestion, just put a break point if there are any lookups and check the data in internal tables if everything is as expected.
Hope this helps.
Thanks,
Venkata Naresh

Error for the fact table while processing the cube - attribute key cannot be found when processing

Please help as I am new to SSAS and this is urgent requirement. This is a MOLAP cube and below is the error that I am receiving when processing the cube. The cube is set to Prrocess Full. Several similar errors are popped up for various dimensions.
"Errors in the OLAP storage engine: The attribute key cannot be found when processing: Table: 'Fact_Table', Column: 'ID', Value: '1'. The attribute is 'Id'. Errors in the OLAP storage engine: The attribute key was converted to an unknown member because
the attribute key was not found. Attribute Id of Dimension: 17 - Ves - PoC Cont from Database: DB, Cube: IPNCube, Measure Group: iSrvy, Partition: Partition1, Record: 1."
Thanks in advance.

Thanks for the recommendations David.
It will be really great if you can clear some of my doubts:
To my information, all the dimensions need to be processed first and then the fact table will be processed.
So if the ID's are not present in the dimension tables, then it should not be present in the Fact table either.
Here we found null values in the dimension table and the ID's were present in the Fact table. What might be the reasons causing such situation?
Also how frequently the cube needs to be processed? Currently the ETL which processes the cube, is scheduled in a SQL Job Agent on hourly basis everyday.
Is there any possibilty that the cube might be under processing state and the SQL job for the next run getting executed trying to access and process the cube while it was still processing?

Mapping dimension table to fact table in admin tool 10g

Hi
I have a criteria when it is run uses fact 1 as fact table and gives result, and when I add new column to this criteria an extra dimension(dim1) gets added to query backend and fact 1 changes to fact2.
The problem I am facing over here is both should result same amount for records. but due to new column from dim1 and new fact table fact2the amount varies and inaccruate results have come.
When I have checked the sources for Fact in logical layer i can find these facts(fact1,fact2) where fact 1 is not mapped with dim 1 and fact 2 is mapped with dim1.
Will mapping dim1 to fact1 will solve my problem.. And what would be the steps to add/map dim1 to fact1.
Please suggest.

I just checked back the setting and here are the changed details again.
I have a criteria where when it is run, the backend query is formed with f1 fact table.
And for the same criteria when I add a column c1, the backedn query is formed with f2 fact table and f1 is no more here and one new dimension d1 consisting c1 is getting added.
In both the cases results are different..the expected thing is same results.
Note:
d1 is connected to f2 checked in physical diagram
d1 is not connected to f1 checked in physical diagram.
when I checked the connection between three table in physical diagram. Only d1 and f2 are connected and f1 is not connected to either of table. How to go about this issue.
Please suggest.

SSAS 2008 Using multiple (three) fact tables in the same cube

Hi, I have three fact tables in my cube,
Actions
Events
Visits
Events captures anything that happens, any transaction. It contains parent actions and parent visits, plus other things that business deems as "actions" that change all the time.
Actions captures a subset of Events and has its own transactional structure. Each action has an event, but not every event has an action.
Visits is a completely different subset of Events with a very different transactional structure from both events and actions. Each condition can have an event, but not every event has a condition.
These facts don't have many overlapping dimensions, perhaps a couple of outrigger look-up dimensions, like Codes and Dates.
I am struggling to reorganize the cube in such a way that I don't have to process with errors and unknown dimension members. Is there any specific guidance re: what to do in these situations?

@Victor Rocca
Some dimensions are common, like Dates and Codes, but mostly they are their own dimensions. Visits
and Actions facts have foreign keys from Events in them, so I would prefer to join directly, anyway.
