Two Filter on Two dimensions without constraining the fact table

Hi All,
does anybody know how to avoid the fact constraint when creating a report with two filters on different dimensions?
I have a big fact table with more than 10 Million rows. In the starmodel the is the dimension customer and products. I create a filter on the customer atrribute "Status" and choose the value "Active". Now I add the column "Product Type" from the dimension "Product" to the filter section. When I want to choose a value OBIEE executes a select statement within the fact table. So I have to wait very long to select a value. Is there any way to say OBIEE only to select the dimension table without joining the fact table?
Thank you very much in Advance.
Regards,
Stefan

Hi Stefan,
Generally queries on the dimensions (across dimesions also) always go through a fact. In case, you would like the queries not be through fact table, but just the dimension tables right away, you can set up a separate subject area for them.
You can create a separate subject area based on a dummy fact table to get these prompt values.
Please refer to http://gerardnico.com/wiki/dat/obiee/presentation_service/obiee_parameter_prompt_subject_area for more details on this setup.
Hope this helps.
Thank you,
Dhar

Few dimension values used in FACT tables.

Hello all,
We are trying to know if somebody faced this issue earlier. We have dimension tables containing 5 million records, but the fact table uses hardly 30k of these dimension values. The fact table contains 350 million records, so is there any way to improve the performance of the query in such a scenario, where hardly 20% of dimension values are actually used by the FACT tables.
Thanks and Regards,
Upendra

I guess you meant should not, right ?

Not exists / union - two dimensions nothing in the fact folder, possible???

What I am trying to do is (in functional terms) produce an invoices on hold report.
This has two distinct characteristics - some invoices are coding but on hold (easy - see first part of the SQL below), but some invoices have no coding, nothing in the FACT folder and I need to show two dimension folders which currently only join via the FACT folder - is this possible??
equivalent SQL =>
select supp.supplier_name, inv.invoice_number, inv.invoice_amount, dis.amount, code.segment1||'/||code.segment2
from     AP_INVOICES_MV inv
,          ap_suppliers_mv supp
,       ap_holds_mv hold
,      AP_INVOICE_DISTRIBUTIONS dis
,     gl_coding code
where inv.invoice_key = hold.invoice_key
and    inv.supplier_key = supp.supplier_key
and inv.invoice_id = dis.invoice_id
and   dis.code_key = code.code_key
and   hold.holds <> 'No Holds'
union
select supp.supplier_name, inv.invoice_number, inv.invoice_amount, 0 amount, 'XXXXX/XXXX' gl_code
from     AP_INVOICES_MV inv
,          ap_suppliers_mv supp
,       ap_holds_mv hold
where inv.invoice_key = hold.invoice_key
and    inv.supplier_key = supp.supplier_key
and   hold.holds <> 'No Holds'
and   not exists
(select 'x'
from    ap_invoice_distributions dis
where dis.invoice_id = inv.invoice_id)
order by 1, 2, 4 ascMy problems are; -
1. is that the second part of the union (not exists section) requires me to join two DIMENSION tables without going via the FACT table is this possible?? (If so how - what JOINS would I need on between the FACT and the DIMENSIONS and would this significantly impede running speed generally)
2. Given that even when writing direct database requests the FROM part of the SQL is the subject area, not the tables, the tool writes the joins for you, how can I write the equivalent of the above??
n.b.
AP_INVOICES_MV - DIMENSION
ap_suppliers_mv - DIMENSION
ap_holds_mv - DIMENSION
gl_coding code - DIMENSION
AP_INVOICE_DISTRIBUTIONS FACT
With the structure following the classic STAR with all folders described in the dimensions equi joining to the FACT folder, BUT some in the invoices dimension will not have corresponding values in the FACT folder (un-coded invoices).
With thanks for your input,
Robert.

MDX : How to use filter on a dimension without showing it OR merge 2 attributes of the same dimension?

Hello everyone,
I'm kind of newbie with MDX language, I'm trying to get filtered measures from a cube with a specific layout.
Here is my exemple :
I want to get all the "order numbers" where the "invoice" cost is more than 300. Each invoice is linked with an ID, one order number can have several invoices.
So what I do is a select request with 2 dimensions : "order num" and "id_invoice"
Here is the result : I get all the cost sorted by "order num" and I can easealy identify those who are above 300
order num
Id_invoice
cost

How is it possible to use a filter on a dimension without showing it or merge 2 attributes of the same dimension ?
The problem is that if I show "id" column, the filter doesn't work properly : it compares 300 with the total cost of the whole order and does not compare with each invoice (which could be under 300 ! - see "KO" in Total2 column)
Here is the request I use to generate this result :
with
member [Measures].[Total]
as (
[TP].[ID INVOICE].[All],
[TP].[ORDER NUM].currentmember,
[Measures].[COST]
member [Measures].[Total2]

Force a GROUP BY to a dimension without including the column in the SELECT

Post Author: ewagener
CA Forum: Desktop Intelligence Reporting
I have a SUM measure object in my universe that has a Select statement consisting of a COUNT(distinct([Some column on Fact Table])). I would like to force a join to a dimension table and subsequent GROUP BY statement for one column on the dimension table anytime that this measure object is used.
I know that I can force the join from the fact table to the dimension table by simply putting the join syntax in the WHERE clause of the measure object. Example
SELECT COUNT(distinct ([Some column on Fact Table]))
WHERE FACT.DIM_KEY = DIM.DIM_KEY
The SQL that BusObj generates is correct and a join is made whenever the object is used, even by itself. Now I want to force BO to include a GROUP BY clause for one of the columns that is on the dimension table, while not forcing the user to select that column in the report. The SQL that I would like BO to generate is:
SELECT COUNT(distinct ([Some column on Fact Table]))
WHERE FACT.DIM_KEY = DIM.DIM_KEY
GROUP BY DIM.FIELD_A
I know a u201Cwork aroundu201D is to just include FIELD_A in my report and then hide it or remove it from the results. This works because I have the appropriate join defined in my universe linking the fact table to the dimension table on the PK/FK relationship. My report writer user does not want to have to add the column then remove it from the report, however, even though it gives her the correct answer. She has asked if we could do all of that behind the scenes. I also know that the ultimate solution would be do declare another fact grain and either use a view or a new fact table altogether. It may come to that, however, I am looking for a quick solution to just force the object to do a GROUP BY to a field in a dimension not selected in the report.
Thanks,
Ed

i think you have to revise the Structre Query Language of your DBMS
there is nothing called Group by without a dimension to group by it
good luck

How to update view without modifying the base table ?

Hi,
I'm not sure what you're asking in either question. It would help if you gave a specific example of what you want to do.

1. How to update a view without modifying the base table ?You can't.
Views don't contain any data; they just query base tables.
You can change the definition of a view (CREATE OR REPLACE VIEW ...) so that it appears that the base table(s) have changed; that won't change the base tables.
2. How to write a file unix operating system in pl/sql ? is there any built in procedure is there ?The package utl_file has routines for working with files.

Display master data without data in the fact table

Characteristic 0PROJECT
Attribute Price
I want to show in the query all the prices including the projects that don't have registers in the fact table.
How do I do this?
Tnks.

I believe you are describing what SAP referes to as the Slow Moving Item scenario. Search SDN using that phrase and you'll get hits on documents and Notes that talk more about this. Here's something from an old How To
Slow Moving Item Scenario
You want to define a query that displays all products that have been purchased only
infrequently or not at all. In other words, the query is also display characteristic values for
which no transaction data or only low values exist for the selected period.
Procedure
In the Administrator Workbench;
1. Create a MultiProvider consisting of a revenue InfoCube, containing the InfoObject
Material (0MATERIAL), and the InfoObject 0MATERIAL. The InfoObject must be set as
an InfoProvider in InfoObject maintenance. In other words, you need to have assigned
the InfoObject to an InfoArea. (also refer to Tab Page: Master Data/texts [Ext.]).
In the BEx Analyzer:
2. Select your MultiProvider in the Query Designer.
3. Define a query that contains the InfoObject 1ROWCOUNT in the columns.
The InfoObject 1ROWCOUNT is contained in all flat InfoProviders, that is, in all
InfoObjects and ODS objects. It counts the number of records in the InfoProvider.
In this scenario, you can see from the row number display whether or nor values
from the InfoProvider InfoObject are really displayed.
4. Save the query and execute it. All values are now displayed, including those for materials
that were not purchased.
If you filter by time (0CALYEAR, for example), values from the InfoProvider
InfoObjects are not displayed since 0CALYEAR is not an attribute of
0MATERIAL. You can see this from the absence of values in the 1ROWCOUNT
column in the query. If you want to restrict by time, you need to proceed as
follows:
Constant Selection for the InfoObject
You need to set the constant selection for the 1ROWCOUNT key figure in order to be able to
set a filter by time in this query.
1. In the Query Designer, via the context menu for 1ROWCOUNT, choose Edit.
2. On the left hand half of the screen, under the data package dimension, select the
characteristic InfoProvider (0INFOPROV) and drag it into the right-hand screen area.
3. From the context menu for the InfoProvider, choose Restrict, and restrict across the
InfoProvider InfoObject.
4. Also from the context menu for the InfoProvider, choose the function Constant Selection.
5. Save the query and execute it. You can now also set a filter for a time characteristic, the
materials display remains as it was.
Displaying Slow Moving Items
SAP Online Help 05.11.02
MultiProviders 3.0B, Support Package 07 10
If you want to display a list of slow moving items, excluding products that are selling well, you
need to proceed as follows:
1. In the Query Designer, via the context menu for 1ROWCOUNT, choose Edit.
2. Via the context menu for InfoProvider, choose the function Display Empty Values. Also
select Constant Selection.
3. Save the query and execute it. The result is that the system displays the materials for
which there was no revenue.
Displaying Products with Small Revenues
If you want to display a list of products that have not been sold or have only been selling
badly, you need to proceed as follows:
1. Set constant selection as described above, but do not select the display empty values
function.
2. In the Query Designer, define a condition for the 0MATERIAL InfoObject. Specify a value
that is to be the upper limit for a bad sale.
3. Save the query and execute it. The result is that the system displays all materials that
have not been sold or have been selling badly.

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:

To find the size of the fact table and dimension table

Hi experts,
Can anyone plz tell me if i want to find size of the fact table and size of the dimension table to find cardinality and line item do we first build statistics then find size by transaction DB02 or any other method we have?
Thanks in advance

Hi ,
Please go to Tcode DB02 >Space>Table and Indexes.Give your table name or pattern (like /BIC/F* for gettinf all the Fact tables)
.This will give you sizes of all the table.
Also if you want to get list like TOP 30 Fact tables and Dimension Table.Please use TCode ST14, this will give a desired output with all the required details.

How we will know that dimension size is more than the fact table size?

how we will know that dimension size is more than the fact table size?

Hi,
Let us assume that we are going to take Division and distribution channel in a dimension and assume we have 20 distinct values for Division in R/3 and 30 Distinct values for Distribution channel .So Maximum, we can get 20 * 30 records in dimension table and we can take rough estimation of records in the cube by observing the raw data in source system.

Dimension table is larger than the fact table

Hi Community,
How can we explain the phenomenon when a dimension table has MORE records in it than the fact table ? What are the conditions that would cause this to occur ?
Thank you !
Keith

Thanks, Bhanu,
I am wondering specifically how to explain the output from program SAP_INFOCUBE_DESIGNS when the dimension table is shown to have a fact table ratio that is greater than 100%
I believe that SAP_INFOCUBE_DESIGNS already takes into consideration both the E and also the F-fact table when calculating the ratio. So in this case, we could not explain it by your first suggestion (after compression - but looking at only the F table).
In the case where selective deletions have been performed, how can we correct the situation ? For example, how could we clean out the records in the dimension tables which no longer have any facts in the fact table ? (I think the BW system should do this automatically as a part of the selective deletion, don't you agree ?).
Also, is there any other explanation for how the dimension table could arrive at greater than 100% the size of the fact table(s) ?
For example, lets say that (theoretically) we placed many very dynamic characteristics together into the same dimension.. which we know you should not do. Would it be possible for the combination of these very many dynamic characteristics to cause so many DIM IDs that the dimension table overtakes the record count of the fact table ? Is this situation then made worse by compression if the number of fact table records is reduced thanks to removal of the request ID ?
