Logical column using union

Hello All,
I have posted a similar thread before,now the requirement is little different ,so i am posting as a new thread
I have a column organization code with values 1000,1001,1002,1003,1004,1100,1101,1200,1201,1300,1301 ....
My customer asked me to create groups like this
Group1 = All 1000's,All 1200's
Group2 = All 1000's,All 1300's
Group3 = 1001,1003,1004,1201
Group4 = 1002,1200,1201,All 1300's
and one logical column should contain all these groups.
create a logical column Logical_Groups which contain all the groups as values.
Its very urgent.please help me out.
Thanks in advance.

Hi,
Thanks for your replies.I have tried your solution(yet to try Nico's ).
I have created a logical column like this.
CASE WHEN
"TestDB".""."Nat_RBM"."PROJECTDATA"."ORG_CODE" IN ('1513', '1532', '1535', '1593') THEN 'Tina' else ''end||''||
case WHEN ("TestDB".""."Nat_RBM"."PROJECTDATA"."ORG_CODE" LIKE '20%') OR ("TestDB".""."Nat_RBM"."PROJECTDATA"."ORG_CODE" LIKE '12%') OR ("TestDB".""."Nat_RBM"."PROJECTDATA"."ORG_CODE" LIKE '36%') THEN 'Jan' else ''end||''||
case WHEN ("TestDB".""."Nat_RBM"."PROJECTDATA"."ORG_CODE" LIKE '20%') OR ("TestDB".""."Nat_RBM"."PROJECTDATA"."ORG_CODE" LIKE '12%') OR ("TestDB".""."Nat_RBM"."PROJECTDATA"."ORG_CODE" LIKE '75%') THEN 'Zack' else'' end
The results its giving is:
Jan : All 3600's
Jack : All 7500's
Tina: '1513', '1532', '1535', '1593'
JanJack : All 2000's,All 1200's
But,what i want to acheive is this
Jan : All 2000's, All 1200's , All 3600's
Jack : All 2000's, All 1200's, All 7500's
Tina: '1513', '1532', '1535', '1593'
Is it possible to acheive this?
Thanks in advance

Logical column using data source from 2 generations of same hierarchy

Hi experts,
I'm using Essbase as my data source in CEIM physical layer,
and I have a hierarchy called "Entity" which contains different level of companies,
in Generation 2 I have only one member called "group totals" and in Generation 3 are 5 members representing 5 different industries,
I need to use these total 6 members as slider on the top of the view(a Dial),
and the measure I want to show is scaled in rate, which I can't simply sum up those five members in Gen3 to get Gen2 measurement.
I tried to create a logical column using Entity-default(the alias table) as datasource, it worked but was not sorted in outline style.
I tried to sort them using calculate items in selection steps, but calculate items seemed cannot be shown as section or slider.
So I wonder if I can simply create a logical column that sourced from different generations(in this case, my Gen2 and Gen3) of same hierarchy,
is it possible to do such things?
Thanks for reply.

You could try General Database Discussions the main db foum.
What are you using to migrate your database? Why is it being mapped from varchar2(8) to varchar2(32). It sounds like someone/something is intervening here.

Derived logical column using Row values in OBIEE11g

Hi Experts
I have a requirement whereby I need to create say 100 new logical column in obiee using the row values of one dimension.
For eg. say I have dimension values like A and B in one of the table , I need to create logical columns like C=A+B and D = A/B and E = AxB as such when the user drags this to the analysis the calculation should happen automatically.
The problem is they are in the rows and not the coulmn , so I can't do plain calculation like sales per Unit = Sales/Units - as Sales and Units are two differnet measure column.
How to achieve this in RPD.
Regds

Hi
Pls. find below the examples :
You have a dimesion called KPI which has soem KPIs.
KPI           Measure Values
KPI1          10
KPI2          20
KPI3          50
etc
Now I need to calulate a driven KPI i.e KPI10 which is KPI10 = KPI2/KPI3 , and I need to do that in RPD.
I know I can do it in Front end analaytics by using Pivot or Selection steps . But I want to do it in RPD.

One logical column used twice in the prompt

Hello Gurus,
I have a report which is presently showing
Sales across country
COuntry Name | Sales
USA 100$
Japan 100$
Country NAme | Statename 1 | Satename 2 |
Usa 50$ 100$
But State 1 and state 2 are one logical column called state in the RPD.
User should have the ability to slect some states in state1 prompt and slect some states in state 2 prompt.
If it is not clear let me know?
With regards!
Alan

In the prompt take the state column... edit the fx as
Case when 1=0 then "any varchar column name" else "State" end
Drag the same column twice in the prompt.. edit the fx as
Case when 1=0 then "any *other* varchar column name" else "State" end
for the both the columns define the presentation variable pv_state1 , pv_state2
so now you have the same column being used in prompts for two states..
In the Report filter add the filters as
state is equal to pv_state1
OR
state is equal to pv_state2
Note-> to add presentation variable in filter, you have to click on Add-->presentation variable
Your report is ready...
Hope it helps...
Thanks

Accessing logical columns using metadata table

Hi,
I have a requirement to store data coming from multiple sources in various format into single table as the number of tables required is not determinable at development phase. Hence I have defined 2 tables,
1. Metadata table storing the information about logical columns in the incoming data.
2. Raw generic table where the actual data would be stored.
While accessible the logical data first I need to access the metadata table to fetch the column details and then access the raw table to provide actual data in those columns. Even though this option is available the code might not remain readable as need to use actual raw table column names in the code.
I have thought of view based access but again number of views required is not known at development time. Is there any option/feature available which would be able to provide logical view for the raw data?
thank you in advance.

Hi
Firstly, this sounds rather messy and is not something I would consider doing - but I shall give you the benefit of the doubt that all other options have been exhausted.
A way I can think of is that you could define your metadata a bit like the oracle data dictionary, then you could use something like APEX where you can use dynamic SQL to show a report on the data. Imagine something like this
DECLARE
l_sql VARCHAR2(32000);
BEGIN
l_sql : = 'SELECT ';
FOR i IN
(SELECT column_name
FROM my_table_data
WHERE table_name = :TARGET_TABLE)
LOOP
IF i = 1
THEN l_sql := l_sql||i.column_name;
ELSE l_sql := l_sql||', '||i.column_name;
END IF;
END LOOP;
l_sql := l_sql||' FROM '||:TARGET_TABLE;
RETURN l_sql;
END;Obviously you can make stick in predicates etc. if you need to but that would be a starting point?
Not very pretty though...
Cheers

New Logical Column using repository variables

Hello all,
Can anyone let me know how we create a new logical column in OBIEE 11g in the BMM layer using the repository variables..Is there any way/chance to create such new logica columns.If so please let me know how we will be doing that

This is alwayz possible.
Here is the syntax.
CASE WHEN VALUEOF(VAR1) ='ABC' THEN
"Sample App Lite Data"."".""."F10 Revenue Facts (Order grain)"."Units"
WHEN VALUEOF(VAR1) ='XYZ' THEN
"Sample App Lite Data"..."F10 Revenue Facts (Order grain)"."Discnt_Value"
END

Adding new column in an existing report which was build using Union

While working in OBIEE 11g I encounter an issue.
My existing report was build using UNION at Criteria Tab in Analysis. Now I have a requirement to add a new column into the same report. For each criteria I have added the new column but when I go back to the "Result Columns". I see a new field added but it is not allowing me to open or edit column properties for that new column & at the same time it is not allowing me to navigate to other tabs like Results, Promts, and Advanced.
I don’t want to build this report from scratch. Is there any workaround to get it resolved?

Hi,
Just check it once the new added column data types are mismatched or not?
and the new added column should be navigated into excluded section, so u should edit the report and dragged into the table column section.
Thanks..

Logical column - Fact measure using Dimension value

Hello all, I have a Fact table that has a metric (Value) where I have set the Aggregation rule to Sum. Now I'd like to create a metric based on the value of a Product Dimension that joins to this Fact table. So I create logical column that has the syntax - Case When Product_Desc = 'A' then Value else 0 End.
The issue is in Answers when I bring this new metric in it doesn't bring in the correct value, are there steps I am missing with creating this metric?
My assumption is if I just bring that new metric in by itself it would return one record - A sum of the Value where the Product = 'A'.
Thank you

Hi BRizzle,
In your scenario, you creatre a calculated measure using the employee dimension, and then this measure show "#VALUE" on the pivot table, right? It seems that it's a limitation of using calculated measures in SQL Server Analysis. Calculated measures cannot
be secured using Dimension Security in a straight forward manner, in fact they won't be listed at all in the Dimension tab of the role where we define the Dimension security. When such measures are browsed in client tools like Excel, the value that would be
displayed is an error value like #VALUE. For the detail information about it, please see:
Limitations / Disadvantages of using Calculated Measures / Calculated Members in SSAS

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?

Why logical column in terms of other logical columns and not physical sourc

Hello
Can someone shed some light that in what scenario ..defining a logical column in terms of other logical column is beneficial compared to defining logical column in terms of physical sources?
I found something on google that said defining in terms of logical columns is like one time thing. I dont understand, even if you define in terms of physical source that' too one time.
In both the case we build an expression specifying which logical or physical columns.
Thank you

well logical columns from physical source, if in logical fact table you can set aggr rules. Logical columns based on other logical columns you can not. Logical columns based on other logical columns will inherit the aggr rules. So for instance, if you create col1 and col2. Both based off physical and both having sum aggr rule. If you create logical column col3 based off these two as such "col1"/"col2" it will produce the following sum(col1)/cum(col2). Now if you really wanted sum(col1/col2) then you should have made col3 based off physical as col1/col2 with aggr rule of sum.
Also of some note, all logical columns based off physical will be performed in the inner most query. So for my example above to get col3 where it is logical col1/logical col2 or sum(col1)/sum(col2) the physical query will be:
select D1.c1/D1.c2
from (
select sum(col1) as c1,
sum(col2) as c2
from tableA
) D1
So my short summary of this, is what or how do you want your sql to be created. Based on this can you lead you to your answer of whether to use logical col based on physical or other logical columns. And unltimately, check the sql generated from your work to ensure the sql queries generated are what you want and expect.
I hope this helps!

How to create logical columns for current period and prior period

Hello all.
Is there any way in obiee to create a new logica column in BMM layer that says "CURRENT PERIOD" AND "PRIOR PERIOD" OR ONE SINGLE COLUMN THAT SAYS "PERIOD".
In those columns what I need is if it a current period column it shoould have 03/01/2012-03/31/2012 (this month date range)
and in prior period column I shouldhave 02/01/2012 -02/29/2012(which is previous month date range).These columns I will be using in my reports.
Please help me if we can create any such columns with these conditions/requirements

Hi,I have already created he dynamic variables.But I am not getting how to use those variables and create the new logical columns in bmm layer.
this is what I am trying
case when VALUEOF("Current Month begin date"."Current Month begin date") ='..' and VALUEOF("Current Month end date"."Current Month end date")
='..' then 'current period' end
I don't really understand what I should write case when VALUEOF("Current Month begin date"."Current Month begin date") ='..'??

How To Create Logical column For Lastyear To Till Date

Hi All,
I Have to calculate Lastyear to Till Date for Logical Column.
Ex:I have Time Dime and Fact column and Dimension columns.
jan 2011 to oct 2012.
Please Let me know.
Thanks,
Abhi

Looks like you are not reading my messages
Since you are doing on logical columns getting this error.
Try this using physical columns then count from aggregate tab
CASE WHEN "Oracle Data Warehouse"."Catalog"."dbo"."Fact_W_SRVREQ_F_Open_Date"."OPEN_DT_WID" > 20110101 THEN "Oracle Data Warehouse"."Catalog"."dbo"."Fact_W_SRVREQ_F_Open_Date"."SR_WID" END
The same you can go with your variable
Or else the same can do by duplicating the existing Fact - CRM - Service Request"."# of SRs" and just add above code.
or just use the below you dont use sum since already aggregation is happend for # of SRs
CASE WHEN "Core"."Dim - Date"."Year" = VALUEOf("Warehouse Refresh Date Last Year"."CURRENT_CALENDAR_YEAR_LAST_YEAR") AND "Core"."Dim - Date"."Date" < VALUEOF("Warehouse Refresh Date Last Year"."LAST_REFRESH_DATE_LAST_YEAR") THEN "Core"."Fact - CRM - Service Request"."# of SRs" END
Hope this works, mark as correct

Logical Column(s) a.k.a. Pre-calculated Measures

I am looking for best practices around logical columns either in Presentation Layer or Business Layer. Specifically I want to know..
1) Is it advisable to have logical columns?
2) How many are good to have? Should one create logical columns for all frequent calculations which are done on dashboards?
3) Are there any performance implications?
4) Can we use Time Series function with logical columns? Like AGO etc.
In short I am looking for intelligent pros and cons of such implementations.
PS: Logical columns are derived from physical columns. For e.g. Profit = Income - Expense.
Regards.

Hi
1) all complex logic should be in the BMM layer in the RPD. Yes, it's advisable to have them in the BMM. Although another good practice is to try to delegate all complex calculations to ETL if possible.
2) As many as deemed necessary. Yes.
3) No, not really. But if you use Answers' logical columns - you have to be creative in propagating them to other reports.
4) Yes you can. But again, this is something that's better to have in the RPD.

Logical column currency format properties at rpd level?

I need to show the currency amount with dollar symbol for a logical column and that should happen at rpd level.
Is there anyway we could do that ?
thank you

Hi User.
You can have logical column name as 'Amount in $' or 'Amount in Dollar'
this is the best practice..
Then if you want value to be suffixed by $ , you can go for data formatting in column properties.....
this is commonly used....
mark if Correct/helps .
