More than one fact tables...

Hi.
I have tried OLAP until now with only one fact table.
But now I have more than one. To start i added one more.
I am always using SOLVED LEVEL...LOWEST LEVEL.
I am always receiving the following error when creating the cube with this measures:
"exact fetch returns more than requested number of rows"
What shall I look for when dealing with more than one fact table?
Thanks.

:: ... and still have a very poor performance ...

1.
Well ... I saw the global star schema and we have two fact tables there!!!
Do I have to build different cubes for each fact table always?
2.
I have built cubes, created a java client and a jsp client.
Performance is much better in JSP using the AppServer(sure!).
The power of the JSP client is more limited i presume.
I wonder if I can do things such setCellEditing for a crosstab in both.
3.
Some aggregation questions:
Everytime I create a cube using CWM2 and also a AW using AWM wizards with that cube I have one aggregation plan by default that processes everything online.
After that I create and deploy my own aggregation plan.
My question is: If I don't want to aggregate anything!??! I want to see, for instance, in BiBeans the lowest level values only. And everything at the top levels empty.
I am missing something 'cause I still have everything aggregated !!!
Thanks.

ORA-01776: cannot modify more than one base table through a join view

I have created EO based on a database view than consists of two tables, and only one is updateable.
When I try to update a row using EO, I got a following message: "ORA-01776-cannot modify more than one base table through a join view"
In Forms, this issue is resolved by setting "Query Only" property of non-updateable items to "True".
Is it possible to do something like that in ADF BC?
Thanks

Thanks for answer.
When I set "updateable" property to "Never", that attribute is protected from any change.
I'm sorry for incomplete usecase.
I have set up a list of value on that attribute, because it is a lookup field for another table and I need to get an ID from that table.
Basically, I need that attribute to be updateble for BC, but not for database.

Cannot modify more than one base table through a join view

hi guys, my current problem is that i have a datablock based on a view, now all the fields bar 1 are updateable, but this one field that is obtained through a join is displayed, the user can enter data in this field which then pupulates other fields which are required, but this specific field should not be updated. Is there an option to state this as i keep getting the error:
cannot modify more than one base table through a join view
Any help would be greatly appreciated, thanks.

the user can enter data in this field which then pupulates other fields So, using the value of "this field" you then query the rest of the fields? Can you show us the code you use to populate the rest of the fields?
but this specific field should not be updatedHave you tried setting the "Query Only" property of the field to "Yes" and the other DML properties (Ins, Upd, Del) to No?
Also, what is your Forms version?
Thanks,
Craig B-)

Logical table having more than one Logical table sources

Hi ,
Is it possible a logical table has 2 logical table sources and there is no join between the underlying table of logical table sources?
What will happen if we create the request which contains one attribute from each source?
Will BI server return records with Cartesian join?
Is it mandatory if logical table is having more than one logical table sources(exp. Logical table sources are X,Y and underlying table is A,B respectively),
The underlying tables (A&B) must be joined ?
Can someone explain the logic behind the logical table sources? How does it work?
Any reference of document will be appreciable.
Thanks,Ashish

Hi Stijn,
Thanks for response.
You are saying that Oracle BI server will run a query against both tables and combine the results. But if there is no possibilty of any type of join, how BI server will combine the results from both tables.
I have a scenario like below -
Suppose i have 2 tables A and B at physical layer. Both table contains the information of any common subject area.
But there is no attribute is common between A and B so not any kind of join possible between two.
Now if i create a logical table with 2 logical table source A and B and create any request having one column from A and one from B ,
What will happen? How BI server will combine the result? Will BI server not result records after Cartesian join.
How can i model this scenario?

How to Create Field Catalogs (More than one Source Table)

Hi Data Archiving Experts,
Could you please help me how to create the Field Catalogs (More than one Source Table). If any one is having example that will help.
My scenario:
Currently we are archiving on CRM Data archiving project. We are facing one issue on creating field catalog with more than one source table.
Ex: ST -- BP1
BP2
BP3
ST info store in one table and BP1 -- BP 3 info sotre in another table. with current field catalog we are getting ST -- BP1. Our requirment is we need to show the ST -- BP3 How we can achive this.
Regards,
Srini

Hi,
I don't think its possible to create fieldcatalog for different tables,
but if you want to do so create a dummy table which has all the fields which you want in fieldcatalog.
populate the data from different table to that dummy table
then create fieldcatalog for that table and pass it in the function module...

Siddarth

More than one Detail table in the Master Detail forms!

Hi,
I need to have more than one Detail table in Master Detail Forms.
I want to see the details of the rows of the first Detail table in the Second Detail table. Please guide me to do this.
Sincerely yours,
Mozhdeh

You can do one of two things
1) Depends on the nature of your data model. I was able to manage many to many
relationships using views and instead of triggers. This solution is somewhat complex but can work in certain situations.
2)Works for situations where master record exists. create a page with mulitple portlets syncronized on some related key.
create the following package to use on the md forms to place on the one page to be rendered.
-- this package will facilitate the storage and retrieval of keys used by the related forms.
create or replace package session_var
IS
session_parms portal30.wwsto_api_session;
g_domain varchar2(2000) := portal30.wwctx_api.get_user;
function get_id (id in varchar2) return number;
PROCEDURE SET_ID
(ID in VARCHAR2
,p_val in VARCHAR2
,P_URL in VARCHAR2
END SESSION_VAR;
create or replace package body session_var
IS
--pkg body
function get_id(id in varchar2) return number is
l_store_session portal30.wwsto_api_session;
l_id number;
begin
l_store_session := portal30.wwsto_api_session.load_session(
p_domain => session_var.g_domain,
p_sub_domain => 'your domain');
l_id := l_store_session.get_attribute_as_varchar2( p_name => id);
return l_id;
end get_id;
PROCEDURE SET_ID
(ID in VARCHAR2
,p_val in VARCHAR2
,P_URL in VARCHAR2
IS
l_store_session portal30.wwsto_api_session;
begin
l_store_session := portal30.wwsto_api_session.load_session(
p_domain => session_var.g_domain,
p_sub_domain => 'your domain');
l_store_session.set_attribute(
p_name => id,
p_value => p_val );
l_store_session.save_session;
* Redirect to the page using p_url;
portal30.wwv_redirect.url(P_URL);
end set_id;
END SESSION_VAR;
--the form master detail form, section before display page enter the following code and publish as portlet.
declare
l_fs varchar2(4000);
l_s varchar2(4000);
v_con_id number;
begin
v_con_id :=rfq.session_var.get_id('CON_ID'); -- primary key and key used to relate details
p_session.set_shadow_value( p_block_name => 'MASTER_BLOCK',
p_attribute_name => 'A_CON_ID', -- attribute on form related to primary key
p_value => '= '|| v_con_id,
p_language => portal30.wwctx_api.get_nls_language ,
p_index => 1
l_fs := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK', p_attribute_name => '_FORM_STATE');
l_s := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK', p_attribute_name => '_STATUS');
if l_fs = 'SAVE' and l_s is null then
WWV_MASTER_GENSYS_1(p_block_name => p_block_name,
p_object_name => p_object_name,
p_instance => p_instance,
p_event_type => p_event_type,
p_user_args => p_user_args,
p_session => p_session);
p_session.save_session;
end if;
if l_fs = 'QUERY_AND_SAVE' and l_s is null then
WWV_MASTER_GENSYS_1(p_block_name => p_block_name,
p_object_name => p_object_name,
p_instance => p_instance,
p_event_type => p_event_type,
p_user_args => p_user_args,
p_session => p_session);
p_session.save_session;
end if;
exception
when others then
PORTAL30.wwerr_api_error.add(PORTAL30.wwerr_api_error.DOMAIN_WWV,'app','generic','onLink', p1 => sqlerrm);
raise;
end;
--then create other md forms and publish as portlets in a similar manner.
-- create a form (form_session_vars) to call procedure session_vars and place the following code in the
addiontional pl/sql tab
WWV_GENSYS_1(
p_block_name => p_block_name ,
p_object_name => p_object_name,
p_instance => p_instance ,
p_event_type => p_event_type ,
p_user_args => p_user_args ,
p_session => p_session);
--then create a page and place the md forms created above as portlets on the page.
--create a link and target the form_session_vars and in the link target inputs
enter the values for your user parameters
id= CON_ID --"your primary key name"
p_url= url/page/"your_page"
--finally create a report (QBE or standard).
in the column formation section use the link created earlier to direct the user to the target page.
How it works.
When the link is selected the form_session_Var is called and automatically runs setting the primary key values
in the user session store. The step is required or the resulting page will not render properly. Then the user is redirected to the page where the portlets are rendered. The portlets start rendering, the before display page calls the session vars package to retrieve the key and put the form into query_update mode returning the data.
The portlets finish in query_and_save mode with details in update mode, the allowable insert, delete and none actions will be available for the details.
benefits: The session_Var package code is resuable as well as the form form_session_Var and the link. passing the key name and values are done at the report level and detailed in the report links. the md forms will need to reference their related keys.

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.

Common diemsions and more then one fact table join problem

Hi,
I have 5 common dimension and 3 fact table which in the same subject area. When I want to display results from more then one fact table sending database then query more then one and I think BI server join this two different result on OBI server. But I think if obi server sending database query for exp. WITH SAWITH0 .... the results get effective.

I find solution on Oracle® Business Intelligence Suite Enterprise Edition Release Notes.
If you use a version of Oracle Database 10g Release 2 prior to 10.2.0.3, then you might encounter an issue with a Full Outer Join that causes severe database performance issues and appears to hang the database when the Oracle BI Server sends to the database SQL queries that include WITH clauses.
To work around this issue when using Oracle Database 10g Release 1 or 2, upgrade to Oracle Database 10g Release 2 Patch Set 2 (for 10.2.0.3). For performance reasons, this is the preferred workaround.
To work around this issue without installing Patch Set 2, modify the Database Features table using the Administration Tool. This configuration prevents the Oracle BI Server from sending SQL constructs that expose the issue in an unpatched Oracle Database 10g.
To modify the Database Features table:
In the Administration Tool, open the properties of the Physical Database metadata object.
Navigate to the Features tab.
Ensure the values for the PERF_PREFER_MINIMAL_WITH_USAGE and PERF_PREFER_INTERNAL_STITCH_JOIN entries are selected, that is, set to True.

Table referenced by more than one other table

I'm no DBA so I was wondering if you could answer this fairly basic question. If I have a table that references more than 1 other table. For example Order links to a customer or Order can link to an Employee how would I represent that in the data model?
I'm guessing I could have the Order table have both an Employee ID and a Customer ID columns and null one or the other out depending on whether it was linked to an Employee or Customer but that seems a bit redundant in that there would always be at least one column being null.
Perhaps I could use table inheritance and just add the relevant foreign key col on the inherited tables but I'm fairly sure you can't have abstract tables.
Thanks for the help.

For example:
table a = Primary_key1, col2, col3
table b = Primary_key1, primary_key2, col3
table c = Primary_key2, col2
To join all this tables you must do something like this:
select ....
from tablea,tableb,tablec
where tablea.Primary_key1=tableb.primary_key1 and
tableb.Primary_key2=tablec.primary2;

Combining more than two fact tables

Hi,
I have been reading many texts about combining fact tables but i still haven't find answer to my question.
I have four fact tables that i would have to combine in to one. That's a simple task but is there anyway the to avoid joins when querying only one fact?
So am i waisting my time or is this possible?

Hi,
I think this is possible. I have not tried this in my enviroment yet, but how about creating multiple LTS for these facts. I mean you could create multiple LTS (as per your queries of course though) for each of your facts and some combinations of them.
So, whenever there is only one fact table needed to be queried, BI Server can intelligently pick up the correct LTS but do not need to do an unnecessary join between the huge facts.
Hope this helps.
Thank you,
Dhar

More than one root table ,how to design cache group ?

hi,
each cache group have onle one root table , many child table ,if my relational model is :
A(id number,name ....,primary key id)
B(id number,.....,primary key id)
A_B_rel (aid number,bid number,foreign key aid referenc a (id),
foreign key bid referenc b(id))
my select statement is "select ... from a,b,a_b_rel where ...."，
i want to cache these three table , how should i create cache group ?
my design is three awt , Cache group A for A , Cache Group b for b, Cache group ab to a_b_rel ?
are there other better solution ?

As you have discovered, you cannot put all three of these tables into one cache group. For READONLY cache groups the solution is simple, put two of the tables (say A and A_B) in one cache group and the other table (B) in a different cache group and make sure that both use the same AUTOREFRESH interval.
For your case, using AWT cache groups, the situation is a bit mnore complicated. You must cache the tables as two different cache groups as mentioned above, but you cannot define a foreign key relationship in TimesTen between tables in different cache groups. Hence you will need to add logic to your application to check and enforce the 'missing' foreignb key relationship (B + A_B in this example) to ensure that you do not inadvertently insert data that would violate the FK relationship defined in Oracle. Otherwise you could insert invalid data in TimesTen and this would then fail to propagate to Oracle.

How to extract data into excel file from more than one internal table

Hi Guys
             I want to extract the data from module pool screen.
             In screen there are two internal tables
                  1. header
                  2. items.
             I want to extract the data as same format looking in the screen.
             With simple Download FM we cannot do this one, because in this we   will display as continuous rows.
<b> But my requirement is saving as table with heading, date, header details</b>
Note that it is not the simple down load . Suggest me with example coding

Hi Guys,
I think it depends on which software you will use to see the result.
If U are using Excel, it's very easy to achieve it.
1. Define a structure as string, the lenth depend on your need.And use the structure to define a internal table, supposed is as A..
