Foreign Key join between two columns in a dimension to one column in Fact

Hi,
I have a requirement to join two columns in a Dimension to the same column in the fact.
My reports contains columns from this dimension and will need to use both the joins to get the correct values. So I am not sure if I create an alias to join the second column, if that will be output incorrect values.
How can we achieve this so that I can still use columns from the dimension and still run both the joins in my SQL eventually.
Dimension
Column 1
Column2
Fact
Column 3
Need to map Column1--->Column 3 and Column2 -----> Column 3
Thanks

I put it in Dimension and dimension extension scenario with a fact
The possible scenarios are:
1) Column1--->Column 3 and Column2 -----> Column 3
Both Column1 and Column2 have their own logical tables in BMM
2)
Column1--->Column 3
Column1--->Column2
In this case You have Logical table with 2 different sources Column1 and Column2 using column mapping.
you can go for multiple logical sources in this case, based on column selection tables in the join condition

Multiple foreign key joins between two tables

Hi,
I have a question about building a repository.
I have a date dimension and one fact. The fact table has about 10 foreign key columns that link to the date Dimension.
In this case should I create 10 aliases to create joins in the Physical and BMM layer or is there any other way to handle this situation.
I am asking this question because 10 aliases can get very confusing for me at the later point of time while creating reports.
Using OBIEE 10.1.3

Hi
I have a follow up question on this.
I am okay with not seeing the different date tables under the Subject area. Even if it just shows a it as a Simple DATE Dimension I am good with it.
In this case which is the efficient way, creating 10 aliases or creating 10 joins in the physical layer. I just figured out that we can create multiple joins between the same set of two tables but do not know how will that effect the way BI server works.
Please help me in understanding this concept.
thanks

Regarding Foreign Key Joins

Hi Gurus,
I learnt that its not practical to use Foreign Key joins in the Business Model and Mapping layer. Why is that, i tried a simple Sample Star schema that uses only Foreign Key joins instead of Complex Joins in BMM Diagram, The RPD is consistent and is running successfully on BI Server.
What is the drawback if i did so and why is not recommended?
Regards,
Sreekanth.

Complex joins allow the BI Server to choose the best route between logical tables in the BMM layer based on the phyiscal joins that exist for the Logical table sources within those tables.
With an FK join your limiting the choices BI server has when it generates the ideal SQL to accomplish the request.
The complex joins allow :
easier config,
BI Server to navigate across different levels (for example Day and Month) when using different level facts.

Hi,
I've two lists in my view with join. The list A and the list B.
I'm ordering the view with the column list A.
The column list A it's a column for type lookup to list B's column.
In my view i'm ordering with the column list A of type lookup.
The view with join is not ordering in order growing.
I want the view will be ordering by order growing.
Do you understood?

Inner Join between two big tables

Hi There,
I have a situation where in which I have to write an inner join between two table of the order of (30k to 60 rows).
My query is as simple as,
select A.a,B.b from A ,B where A.a = B.b;
N.B: a and b are of type varchar
But the problem is it takes nearly 15 mins to run. Is there any better way of doing an inner join between such bigger tables?
Thanks,

Joins between two schemas

Hi
I need data from two different schemas. Can develop one subject area taking 2 tables from 2 different schemas or we need to have these two tables from one schema only ?
Can any one help on this.
Thanks
Manu

Hi,
When you try to create physical join between these two tables of different schemas.
The join condition is REGION.REGION_CODE = REGION.REGION_ID
Note: The table name is same in both the schema.
Now as soon as I click on Ok, it gives an error.Because You can not create join between two tables with the same name.
So, create alias for these two tables and try to create the join with the same join condition.
It allowed me to create join perfectly. I moved ahead with the creation of Subject Area based out of these two tables.
Opened Presentation Services, selected few attributes from both the Presentation folders.But it gave ODBC error as :
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 46036] Internal Assertion: Condition m_CountFields == static_cast<int32>(m_ColumnNameVector.size()), file .\Src\SQCSCacheStorageListStream.cpp, line 221. (HY000)
Now in order to fix that issue, rename the base tables as Schema1_name.REGION and Schema2_name.REGION in the repository.
Reload the rpd and run the same report, it would give correct result.
But instead you can have the tables in the same schema for better maintenance activities.
Hope this solved your question.

MuRam

Doubt on creating join between two tables

Hi friends,
I have two tables , ekes and eine
my requirement is if Ekes-ebtyp = 'X1'.
then Ekes-ebtyp = EKES-EINDT + Eine-j_3alitra.
the doubt is there is no primary key common between this table . actually in my whole program for purchase order i used EBELN for extracting details when two tables are involved . in this two tables no two primary keys are common to extract data ...is there any ways please suggest..
the code i wrote is
loop at li_ekes assigning <fl_ekes>.
read table li_eine assigning <fl_eine> with table key (here i need to give some unique fields to join these two fields please guide me which field i can use.).
<fl_ekes>-ebtyp = <fl_ekes>-EINDT + <fl_eine>-j_3alitra.

Hi,
Both tables have field EBELN in common.
You can use it to extract data from both.
Hope this helps.
reward if helpful.

How to insert a local member in a column between two different nested row dimensions

Hi Experts,
We have a report which has two dimensions in rows with nesting. The dimensions are PROGRAMS and ACCOUNT.
I have attached the layout of the report.
We need to have a column for local member in between Col A and Col B, wherein we have to pull the long description of the program.
We have long description of programs maintained in a property of PROGRAM dimension
So if we can insert a column between Col A and Col B, we can have a local member in it with formula "EPMMemberProperty" refering to Col A
Currently we are are not able to insert a local member in between Col A and Col B in EPM 10 SP 14 version because its not a data range
I remember we used to do it in BPC 7.5 using expansion ranges to insert a blank column. So I believe similiar thing can be done in EPM 10
I have tried the option of VBA macro to insert a column before Col A and populate the long description and then hide Col A. It works. But I dont want to complicate it with Macro, and want to use EPM functionality to achieve the same.
Please advise if this is possible with BPC 10 to have a column for local member in between Col A and Col B.
Thanks a lot in advance.
Regards,
Shiva

Hi Sathish,
Thanks a lot for replying. Since I had to insert the local member in between two dimensions, I couldnt use the position option in the local members. Because positions were staring from the data range.
How ever I have tried the suggestion given by Varaprasad and Bishwajith above and it worked.
Thanks,
Shiva

Outer join between two Contexts not working

Hi,
I have two contexts. A Context and B Context. To define hierachy or to show the both contexts data in single table/report in Web-I, i joined main tables of both contexts with a join. In those main two tables i want to show the table1 data irrespective of corresponding data exist in second table.
To solve that i tried LEFT/RIGHT outer joins but nothing solved my prob. Because of those were in different context, I suppose. But it's not the same case when i work within a context (Single).
Hope you got my prob now...!! Please help me out...
Thank You!!

Thanks Rohit for your reply.
Nope, i can't cpntinue without having that join between those two tables. It must be there to get the exact results.
It's not the prob of using Merged Dimensions... those are useful for another purpose. In my case those two Dimensions have different sets of data and have relation between those two.
Like:
Tab-1------Tab2
Prod1------Cat1
Prod1------Cat2
Prod2------Cat3
Prod3------Cat4
Prod4------(NULL)
As per requirement i should show the row for empty, in my ex it's in Prod4.
If i use two SQL's prob:
I can't relate those two and which have relation more over interdependent. Shows data as two separate tables in report.
If i use multiple dataproviders:
Prob Tab2 is has other joins with other tables to complete the project hierarchy.
Hope you got it...
Thank You!!

How to represent foreign key relationship between entity services

Hi All,
I have two entity services sbu and lob with remote persistensy(web service).In the sql database also i have these two tables.
lob table attributes: lobId and lobName.
sbu table attributes:sbuId,sbuName,and lobId.Here lobId a is foreign key referring to primary key of lob table.
I want to represent this in the entity services.
Can you plz tell me how can i do this?.
Thanks
Sampath.G

Hi Sampath,
to avoid creating a lob entity set the lobId and the timestamp attributes. because this is not smoothly done in the service browser, continue writing your UI.

Foreign Keys b/w two schema

Hi grus
is it possible to make a foreign key on a table in schemaA referenced by a table in SchemaB?

For this you on will go to need the privilege 'references'.
With the <schemaA>:
grant references on <table_schemaA> to <schemaB>
With the <schemaB>:
ALTER TABLE <table_schemaB>
ADD CONSTRAINT <FK_NAME> FOREIGN KEY
("column_schemaB") REFERENCES <schemaA.table_schemaA>
("column_schemaB") ENABLE;
PS.: To substitute the terms that are between < > in accordance with its necessities.

Can we apply join between two internal tables?

Itab has fields A,B,C.
Data: begin of itab occurs 1,
         A type I,
         B type I,
         C type I,
         End of itab.
Jtab has fields A, I, J.
Data: begin of itab occurs 1,
         A type I,
         I type I,
         J type I,
         End of itab
The common field between itab and jtab is u201CAu201D.
Now I need to collect A,B,C,I, J in another internal table ktab.
How should I be doing this.
If I use a SELECT query with inner join between itab and jtab it says u201Citab is not a database tableu201D.
How should I get the result ktab with A B C I J fields?
Please help, nay help will be highly appreciated?

Do you have the above code in ?
Here A is common field between both tables, first we are appending itab_1 & itab_2 into table itab_all then deleting the adjacent duplicates from itab_all. then we are reading itab_1 & itab_2 for possible matches and update the same values in itab_all
so there will NOT be a chance of duplicates in itab_all
