Logical foreign key display values

I have a schema in which the primary keys are auto generated numbers. Foreign keys exist from child tables to the primary key of the parent.
I have figured out how to change auto generated forms to display a dropdown list of display/values to the user on insert or update instead of the meaningless number.
What I can't figure out how to do is have the generated report show the display that I am looking for without losing the ability to edit the child record. As soon as I manipulate the query to include another table I lose the icon in the application to edit the row.
Is it possible to keep the edit icon on the report while showing logical values instead of actual ones?
Thanks in advance,
Chris S.

We'll use a football analogy because it's time for the ployoffs.
Let's create a TEAMS table and a DIVISIONS table.
TEAMS consists of:
TEAM_ID NUMBER -> PK
LOCATION VARCHAR2(35)
TEAM_NAME VARCHAR2(35)
and DIVISIONS consists of:
DIVISION_ID NUMBER -> PK
DIV_NAME VARCHAR2(35)
Now there can't just be a link from a team to a division because they move around a bit. The Detroit Lions used to be in the NFC Central. That doesn't exist anymore and now they are in the NFC North. (Please set aside the fact that the NFC should be a part of the conferences table).
This means that I would create a table to link the TEAM record to a DIVISION record with the season that the team became a part of the division and potentially the last season that they were in that division. This table will be called DIVISION_TEAM_XREF and looks like this:
LINK_ID NUMBER -> PK
DIVISION_ID NUMBER -> FK(DIVISIONS.DIVISION_ID)
TEAM_ID NUMBER -> FK(TEAMS.TEAM_ID)
SEASON_EFF NUMBER(4) (actually a year maybe a VARCHAR2 would be better)
SEASON_TERM NUMBER(4) (nullable)
Now I created all of that through HTML DB with foreign keys from the XREF table to the teams and divisions tables. Then I create an application throught the application builder. I choose report and form and the application type like the demo. for each of the three tables. Choose a theme and walah there is an application with all three tables. If I add data to TEAMS or DIVISIONS I can see them in the report page that is created and there is an icon to the left of each row which when clicked will allow me to edit the row.
The problem comes with my XREF table. The creation screen is just a form which expects me to know the auto generated number that was created for my division and team. I have figured out how to change this in the application builder so that it is a drop down list built from a query of the respective table.
Once I create a record I can see it in the report page for the XREF table. This page has the option to edit the record but the values on the screen are the auto generated numbers that don't mean anything to a user. When I change this page to use display values from the parent tables I lose the edit icon.
Here is the original query that the application builder used:
select
"LINK_ID",
"DIVISION_ID",
"TEAM_ID",
"SEASON_EFF",
"SEASON_TERM"
from "DIVISION_TEAM_XREF"
and here is what I would like to change it to:
select
XREF.LINK_ID "LINK_ID",
DIV.DIV_NAME "DIVISION",
TEAM.TEAM_NAME "TEAM",
XREF.SEASON_EFF "SEASON_EFF",
XREF.SEASON_TERM "SEASON_TERM"
from "DIVISION_TEAM_XREF" XREF, DIVISIONS DIV, TEAMS TEAM
where XREF.DIVISION_ID = DIV.DIVISION_ID
and XREF.TEAM_ID = TEAM.TEAM_ID
Sorry for the long post. Hope that clarifies.

Unable to create foreign key: InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index

I am running an SQL(CE) script to create a DB. All script commands succeed, but the DB get "broken" after creating the last costaint: after running the script, viewing table properties of Table2 and clicking on "Manage relations" gives the following error: Unable to create foreign key: InvalidArgument=Value of '0' is not valid for 'index'.

I know this is kind of old post, but did this realy solved your problem?
I'm getting this same error message after adding a FK constraint via UI on VS2008 Server Explorer.
I can add the constraint with no errors, but the constraint is not created on the DataSet wizard (strongly typed datasets on Win CE 6) and when I click "Manage Relations" on the "Table Properties" this error pop out:
"InvalidArgument=Value or '0' is not valid for 'index'.
Parameter name: index"
Even after vreating my table with the relation in SQL the same occurs:
CREATE TABLE pedidosRastreios (
    idPedidoRastreio INT NOT NULL IDENTITY PRIMARY KEY,
    idPedido INT NOT NULL CONSTRAINT FK_pedidosRastreios_pedidos REFERENCES pedidos(idPedido) ON DELETE CASCADE,

Logical foreign key

Hi All,
I apologize to bring similar question. .
I am able to create the logical foreign key for logical table A with new joining condition (A.2=B.2) (2 is calculated logical column).
However there still exist Physical foreign key join with old condition (A1.=B.1). When I deploy this rpd, the report generates sql with (A1.=B.1) join condition.
Then,I removed this Physical foreign key join in rpd,and got a warning' logical dimension B has a source that does not join with any fact table' in consistency check.
Still after deploying this rpd , I am getting error [nQSError: 14025] No fact table exists at the requested level of detail: in report.
I am missing anything.The logical foreign key has correct join condition still it is not over riding the physical join.
Thanks for going through this question,
http://tinypic.com/r/2qiwmrr/6

Based on your comments I'm looking at documentation:
I found a Note: A logical key for a fact table must be made up of the key columns that join to the attribute tables. Logical foreign key joins may be needed if the Oracle BI Server is to be used as an ODBC data source for certain third-party query and reporting tools.
I need to see why ODBC, and unlike the Logical Foreign key join is not overriding join Physical layer.
Btw: Since you want to go with a join using defined logical column, can you use the same expression in Physical join using expression builder?
This should work.
EX: T43770.DEPARTMENT_ID = case when T43764.DEPARTMENT_ID > 10 then T43764.DEPARTMENT_ID else 0 end

Foreign Keys for a Logical Table

Hi All,
I want to know in which scenarios we create the Foreign Keys for a Logical Table. Once we create the foreign key for the logical table, does it mean that it will automatically override if any joins are there.
Physical Table A, B ( no physical joins)
Logical Table A, B (logical join B(Dim)-->A(Fact))
created the foreign key in logical table A with B .(A.1=B.1)
Will the rpd generate sql with A.1=B.1 join condition for reports.
I tried to create the logical foreign key for logical table A, I could not see any corresponding table option.Here is its snapshot
http://tinypic.com/r/jq1gkz/6
Thanks,
Virat

In general when we go complex joins in Physical layer we go for Logical foreign key joins in BMM layer, best examples is SCD Type-II.
Physical Table A, B ( no physical joins)
-->You need to have a physical join so that this can be override by BMM layer
created the foreign key in logical table A with B .(A.1=B.1) Will the rpd generate sql with A.1=B.1 join condition for reports.
-->Yes you can see this join in BI Physical query.
I tried to create the logical foreign key for logical table A, I could not see any corresponding table option.Here is its snapshot
-->2 cases: 1)You need to delete existing logical joins 2) You might not have join in physical layer.
Hope this helps
Let me know for issues

Dimension foreign key on Fact gets updated with same value

Hi All,
I'm hoping someone has at least seen this problem and can provide insight.
Background:
- We are on OWB 10.2
- Fact table is Billing_F
- Fact table has foreign keys to Customer_Dim, SalesOrg_Dim, Time_Dim, etc.
- Fact table has update mode Update/Insert
Once in a while, every row in the Billing Fact gets updated with the SAME SalesOrg_Dim foreign key column value. In other words, the data would look like:
Before:
Line ID Amt SalesOrg_Key
1 100 19241
2 200 21925
3 140 08585
After:
Line ID Amt SalesOrg_Key
1 100 12345
2 200 12345
3 140 12345
*** The Source tables contain values in the Before table. ***
We can't reproduce this on a consistent basis. The only way to "correct" the data is to rerun the mapping from source -> staging -> fact again. No other change.
Please, has anyone else at least experienced this problem? If so, how were you able to fix it permanently?
Any help is greatly appreciated!
irene

Hi Irene
Difficult to help here without reviewing your mappings/schedule but does SalesOrgKey 12345 represent a particular value e.g. Unknown, Default?
I suspect it's something to do with your load order in that the data in the dimension is not available/ready when the fact is loaded and therefore a default value is being inserted. When the fact load is rerun I'm guessing the load of the dimension has finished and therefore the key lookup returns the proper keys from the dimension. Is the dimension truncated and reloaded?

Displaying values

Hi,

Database diagram not displaying foreign keys

I've created a database diagram by importing tables from a database, and then manually creating the Foreign Keys on the diagram ( they're logical FKs, but not actually on the database ).
Now, when I reopen the diagram, the 'Structure' tab in the bottom LHS initially displays a list of all of the FKs and tables, and then the list shrinks to just 3 of the 15 or so FKs ( plus the tables ), and only these 3 are displayed on the diagram!
I can post the diagram file if someone wants to go through it and find out the problem.
The diagram was created in 10.1.3.1, and will not open correctly in either 10.1.3.1 or SU4.

Can you rename the zip file extension to '.zap' to get it through the mail server.

Display value instead of key in input field with LOV?

Sorry, this is so basic I'm sure it must be easy but somehow I can't find it in the documentation. The LOCATION table contains a foreign key referencing the CLIMATE table. As well as its primary key, CLIMATE has a column called NAME holding the name of the climate (e.g. temperate, tropical, etc.). The user must be able to update the climate value for the location he is working on. So I have a list of values which looks up possible climate names, the user selects the name he wants and the value gets set in the LOCATION table. That works, but the problem is that the input item displays the key value of the CLIMATE record, and I need it to display the value of NAME instead. Of course I can have another field showing the name, but that is messy, the user doesn't understand the key value and shouldn't have to see it. So how do I make one input field display the NAME, while actually updating the key value from the LOV choice?
Thanks

Thank you, Joseba. It does help to some extent. Now I have a non-updatable field with the climate name in it, and below that is the magnifying-glass icon that invokes the list of values. I guess that's not bad, and I can put a label next to the magnifying class saying "Click to select climate". So it's better, but still looks very odd compared to updating fields that are in the LOCATION table itself, where it's an updatable field and the maginfying glass is right next to it. Really the user should not have to behave differently just because the database chooses to hold the value that he wants to alter as a reference to another table.
Is there at least a way to put the list of values magnifying-glass next to the field that displays teh value, rather than underneath it? They are all inside a thing called "af:panelFormLayout", and I tried setting MaxColumns to 2 in its properties, but it still won't let me move the list-of-values field alongside the other one.
Thanks.

Display values for logical columns with several physical sources

Hi all,
I'm enocuntering some strange behaviour with the values displayed for a column (when we want to add it a as a filter, and in the dialogue box select 'Show All' values).
Basically the logical column is mapped against several physical columns as the base fact table is aggregated to different levels. Additionally, one column in the fact tables has an attribute value, and these vary between the aggregated and non-aggregated table. This is not a problem.
In the production environment, when we display the all values in the filters prompt for this column we are seeing the values being taken from one fact table. Naturally this means that not all the values possible for this column are being shown (i.e. values from the aggregated fact tables are missing). Now in one of our test environment where those fact tabels have additional data loaded, the values are being taken from one of the other fact tables. Unfortunately it is not necessarily the fact table with less data.
My questions are:
a) What dictates which fact table the server will use when the query in Answers doesnt use any dimensions (i.e. we are selecting just this attribute and selecting all the possible values by which it can be filtered)?
b) Is there a way of obtaining all the values from the differente physical columns? I.e. that the display values shows the values of that logical column across all the physical fact tables? Maybe we would need to model that attribute as a logical dimension just for that attribute? Im not really sure this would work, as at the physical level the join between the dimension and fact would still have to go to only one particular fact table.
Any info or help is much appreciated.

Hi,
Aggregate tables exist at physical level and are created by ETL procedures. Although i am aware that the dimension come into play when the application needs to decide which source aggregate table to use, it is not an issue here as in our query we are not involving dimensions. We are selecting just this one columen, and then the filter option on this column, then in the dialogue box we select 'All Choices', only the values from one of the source tables is being shown.
This is not a probelm within reports, i think it is a product limitation in that in that option to list all values a user can filter by, it is not possible to display all the values from the different fact tables to which that column is mapped.
Has anyone else encountered this behaviour?

How can we hide the non key field values in the sm30 display

hello experts,
I have to protect the non key field values in the sm30 display , can u help me out wat changes i have to do in the layout.

Hello Gopal,
What do you mean by 'protecting' your non-key field value?
1) You want to display it, but make it non-changeable
A - Make the field as output-only in screen, as already answered by a preivous collegue
2) You do not want to display this field at all
A - Goto the DDIC definition of the view (not possible for a table directly), and maintain the required field as a Hidden. After activating, remember to re-generate the maintenance dialogue. Also, please maintain Event 21, in case you want to access/change the value of this field in background.
3) You want to maintain special validations/checks for the field
This can be easily done by introducing your modules within the CHAIN-FIELD commands in the PAI of the generated screens.
Best Regards,
Rekha

Foreign keys in logical fact

Hi,
Should I define foreign keys in logical fact table? I need to use "aggregation rule=count distinct" of the foreign key column in my reports.
Thanks.
Andy

Hi Andy,
You can add the foreign keys to your fact table as a measure column (count distinct aggregation).
Do not use these foreign keys to create foreign key joins in the logical layer. Always use complex joins (http://obibb.wordpress.com/2010/08/06/joins-in-oracle-bi-ee/)
Good Luck,

Displaying information other than a foreign key in 'interactive reports'

I would be very grateful if someone could help with the following query. I have 2 tables (*Table1* and Table2). Table1 has the following columns:-
Tbl1PrimaryKey, Tbl1Description
Table2 has the following columns:-
Tbl2PrimaryKey, Tbl2Description, Tbl1ForeignKey
Where Tbl1PrimaryKey is the 'primary key' in Table1, Tbl2PrimaryKey is the 'primary key' in Table2 and Tbl1ForeignKey is a 'foreign key' and uses the 'primary key' from Table1.
I would like to create a page which displays the description of Table2 and Table1 on a web page, however, using an 'interactive report' in APEX, the resulting web page displays:-
Tbl2PrimaryKey, Tbl2Description, Tbl1ForeignKey
I would like to change the underlying code to display Tbl1Description instead of the primary key, but I can't get the SQL coding correct. The region source sql code at present is:-
select "Tbl2PrimaryKey",
"Tbl2Description",
"Tbl1ForeignKey"
from "#OWNER#"."Table2"
Any help regarding the above query will be appreciatiated.

Try one of the following in the Source:
in-line query...(My favorite)
select "Tbl2PrimaryKey",
"Tbl2Description",
(select Tbl1Description from Table1 where "Table2"."Tbl1ForeignKey" = Table1.Tbl1PrimaryKey) Tbl1Description
from "#OWNER#"."Table2"
-or-
Classic Join (if Tbl1ForeignKey is NOT NULL)
select "Tbl2PrimaryKey",
"Tbl2Description",
Tbl1Description
from "#OWNER#"."Table2", Table1
where "Table2"."Tbl1ForeignKey" = Table1.Tbl1PrimaryKey
Hope that helps,
Russ

"Item Containing Primary Key Column Value" does not display records

Hello,
We are developing a new page where an "Automated Row Fetch" process is needed.
With other pages we experienced no issues. But with a new one, when defining the value for the field “Item Containing Primary Key Column Value”, Apex displays no rows.
As far as we know, Apex should display all the fields defined for the page. Is there any property which affects the fields visibility?
The affected page has textarea and text fields.
Thanks in advance.

Hello,
Sorry, we have already detected that the problem was at field definition.
Fields should be defined as "Source Type: Database Column". They were wrong defined.
Thanks.

Or what is your question really about? Since you talke about foreign keys etc, I suspect that you want to transfer the entire table definition, but you cannot do that with an INSERT statement.

How to insert value for composed foreign key?

My problem when I update or insert to table Ffclient which has link 1-1 with other table ClientLoan by composes primary key loanId and clienId (break table). I auto mapping by Jdeveloper 10g version 10.1.2. In FfClient table has two fields compose foreign key of ClientLoan as loanId and clienId not nullable. In toplink object Ffclient it only has one reference ClientLoan object by clientLoan field, not has two fields loanId and clienId . When I insert or update to database, I can't set value for these two fields direct so I have created new ClientLoan object and set value for composed primary key loanId and clienId, after that set it to object Ffclient. But when I update or insert to database it occurs exception about insert null for two not nullable fields: loanId and clienId.
Any one has error as mime? Any one help me correct my error.
Thanks in advance.

Yes, many thanks for you reply.
My project has many layer (include DAO + EJB + BO + WEB).
Toplink objects which are auto created by TopLink has only using in DAO and EJB layer, then toplink objects are transfer to Bean objects (valueObject) which are contain primitive java type as int, long, double... not java wrapper object as Integer, Long, Double... Bean objects are using from EJB to WEB layer. So when set value to bean object from toplink object I sometime don't set all reference toplink object to reference object of bean (although bean has references bean object as toplink object) because there are too big. So when I update data from WEB layer to EJB layer, before update to database, I must get fill all data for foreign key of update object by create new reference toplink object, add reference_id to this object and set it to update object. I waste a lot of time, its very handwork and tire. Are you has any solution about this problem?
Thank in advanced.
