New Logical Column Datatype

I am trying to add a new logical column to the BMM layer. But by default the data type is showing as UNKNOWN and is grayed out. How can i change it? I am trying to perform a calculation on the new column added.
Thanks!

Hi,
user10797474 is correct. It takes the default datatype depending on your logic. So in the properties of the column, check the "Use existing columns as source" and then click the button with the three dots. Then create your logic in this expression builder. Select the columns and formulas from the list so you do not have to type them. Once you save from the expression builder, the default datatype should be set.

New Logical Column w/Case Statement

OBIEE 11g
I have a created a logical column in the BMM that I would like to display a certain output if certain criteria are met. I have a case statement like the following:
CASE WHEN COLUMN1 = 'Honda'
AND COLUMN2 = 'Accord'
THEN 'Sedan' ELSE NULL END
However when I run a report in Answers with just the new logical column created it is not showing any values. I have validated that in the dimension table there are rows that meet the above criteria.

I dont see anything wrong in the condition, I've tried with similar case for both based on logical columns and physical columns.
Can you check the physical query for the same to see how its executing?
Between: I think you can go with COLUMN2 to define the type of vehicle is? values you might have used for example, but the more specific column is enough to define the type.

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"

How to retrive new logical column based on flag values in table.

Hi,
i have two tables in rpd
1.file table contains the coulmns------->date,file_count,record_count,cldm_stg,cmsa_stg,archive_stg
2.rejection table columns---------> are same as above
both have same common columns.my requirement is publish a dashboard like:
date | land_files count |alnd_recordscount| target_files count|target_records count|Rejection filecount|rejection record count
These report ineed retrive from those two tables.based on flag values.taget countcomes when all stg values set to ='y'
i.e(cldm_stg='y' and cmsa_stg='y'and archive_stg='y') if not then it will be in rejection file.
Please give solution how to achive my output.

Tanks for ypur reply .only two tables are there named as above.i taken file_control as a fact table.
and i create one new tablecalled target in bmm layer taking logical source as file_control(fact table). and iset the where clause for the new table.and i create a new measure called target_file and target_records.in where clause my query is like
dwbidb."".AUDIT_PROD.FILE_CONTROL.ARCHIVE_STATUS = 'Y' AND dwbidb."".AUDIT_PROD.FILE_CONTROL.CMSA_STATUS = 'Y' AND dwbidb."".AUDIT_PROD.FILE_CONTROL.LND_STATUS = 'Y' AND dwbidb."".AUDIT_PROD.FILE_CONTROL.SCRIPT_STATUS = 'Y' AND dwbidb."".AUDIT_PROD.FILE_CONTROL.STG_STATUS = 'Y'
please tell me if this is right way to achive mt report. and tell me difference between fragmentation and whereclause.for my requrement i ahve to follow which method either fragmentation or whereclause.and in rpd there are no errors and warnings.but in answers i get a follwing error

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") ='..'??

Logical Columns - Running Sum & 3Month Rollover

Hi All,
Need to build a logical column.
I have a column with number of units (count distinct) in RPD.
I need to build a new logical column in the REPOSITORY , such that it has running sum values.... sothat when i pick this #units column and months column in the ANSWERS...I need to get roll over of all previous values for first month.
Say Jan ---> XXXX units ( summation of all previous available units - few years)
Feb----> YYYY units ( sum of till jan values & Feb units)
Mar----> ZZZZ ...etc ( sum of till Feb values & Mar units) so on.
Based on this newly built column I need to build another column of " 3 months roll over " column.
Replies appreciated.
Thanks in advance.

Hi user11939829m
So help me understand your new measures a little better. For the sake of this post, let's say your data is like so
Month Year -- Units
Jan 2010 -- 1
Feb 2010 -- 2
Mar 2010 -- 3
Apr 2010 -- 4
May 2010 -- 5
Jun 2010 -- 6Then let's say you have a report with the above columns and the new running sum columns.
Month Year -- Units -- Running Sum Units
Jan 2010 -- 1 -- 1
Feb 2010 -- 2 -- 3
Mar 2010 -- 3 -- 6
Apr 2010 -- 4 -- 10
May 2010 -- 5 -- 15
Jun 2010 -- 6 -- 21Now what exactly would your three months rollover be? Would the 3 month rolling sum = running sum for current month + running sum for last month + running sum for last last month?
i.e.
Month Year -- Units -- Running Sum Units -- 3 Month Rolling Sum
Jan 2010 -- 1 -- 1 -- 1
Feb 2010 -- 2 -- 3 -- 4
Mar 2010 -- 3 -- 6 -- 10
Apr 2010 -- 4 -- 10 -- 19
May 2010 -- 5 -- 15 -- 31
Jun 2010 -- 6 -- 21 -- 46Not sure what value such a measure would add. Or do you mean 3 month rolling sum would be the running sum for just the last three months (like below)? This makes more sense but in your description, you indicated that you'd build the 3 month rolling sum off of the running sum which confused me a bit.
Month Year -- Units -- Running Sum Units -- 3 Month Rolling Sum
Jan 2010 -- 1 -- 1 -- 1
Feb 2010 -- 2 -- 3 -- 3
Mar 2010 -- 3 -- 6 -- 6
Apr 2010 -- 4 -- 10 -- 9
May 2010 -- 5 -- 15 -- 12
Jun 2010 -- 6 -- 21 -- 15 Is that what you are going for? Please elaborate.
Best regards,

OBIEE - new logical colums fails when sourced from Essbase

I created a new logical column by using locate , substring etc which works fine by itself. Wheen I use that DIM value against a measure , i get these messages
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 42043] An external aggregate is found in an outer query block. (HY000)
SQL Issued: SELECT Portfolio.LOB saw_0, Measures."Number of Exposures" saw_1 FROM cdwzp3013 ORDER BY saw_0
Its true that this modified member does not exist in the essbase . the original member has 'External_aggregate' . If I change the new logical column LOB to 'SUM' .it works but then I have to change all measures and then OBIEE never returns any rows . Probably it takes fior ever to the sum again
Question : Is there a way we can tell OBIEE/Essbase that this modified column is for display only or prompts etc ..but the real filter or sum must be done on the original member name
Thanks

I wonder if cube import only works when using a 32-bit Essbase client?

My request shows a diff Fact table when new Dim columns added to OOB report

Hi,
I am facing this strange problem with the out-of-box BMM metadata mapping and report:
The "Dim_W_GL_ACCOUNT_D" is joined to "Fact_W_GL_OTHER_F" and "Fact_W_GL_BALANCE_F" facts. Both these fact tables have a inner join to "Dim_W_GL_ACCOUNT_D". The change I have made in th BMM is - I added 2 new logical dimensions DimA and DimB and joined these to the above 2 fact tables.
The O-O-Box "GL Account Balance" Report works fine which has 3 logical columns (GL Account Number, Financial Statement Item, GL Account Category) from the "Dim_W_GL_ACCOUNT_D" and 1 Fact column "Closing Amount" which points to the "Fact_W_GL_BALANCE_F"."BALANCE_GLOBAL1_AMT" fact.
When I add 1 logical column each from my 2 new Dims I created, the report output shows the Fact column "Closing Amount" as $0.0. Upon investigating the log, the query shows it is using the "Fact_W_GL_OTHER_F" instead of "Fact_W_GL_BALANCE_F" fact which has the "Closing Amount" column. I am not sure how. When I drop the logical column "GL Account Number" and keep my 2 new logical columns in the request, the "Closing Amount" is shown correctly. I also saw there is a Dim Hierarchy for "GL Accounts" --- the "GL Account Number" is on a lower level than the "Financial Statement Item" and "GL Account Category" columns from the same logical dimension table which are 1 level higher.
How do I make the request pull data at the "GL Account Number" level and still have the query fetch data from "Fact_W_GL_BALANCE_F"."BALANCE_GLOBAL1_AMT" (Closing Amount) with my 2 new logical columns included?
Any help is appreciated. Thanks a bunch.

I was able to fix the problem.

Changes to Derived Logical Column not reflected in Answers

Before I go off my rocker and stab myself with my IPhone lightsabre... :-)
I created a new logical column for an existing table in my BM, deriving from an existing column (a datetime field called ESTIMATEDCLOSE) as follows:
MONTHNAME(Sales.OPPORTUNITY.ESTIMATEDCLOSE) || ' - ' || CAST(Year(Sales.OPPORTUNITY.ESTIMATEDCLOSE) AS CHAR(4))
...which should give me something like "Jan - 2008". The problem is that it returned something like "2008/01/31 00:00:00" in Answers - completely unexpected.
I decided to start out small and try something simpler, changing my derived column to be only Sales.OPPORTUNITY.ESTIMATEDCLOSE. This returned "2008/01/31 00:00:00" in Answers - sort of expected.
Then I changed it to MONTHNAME(Sales.OPPORTUNITY.ESTIMATEDCLOSE). This also returned "2008/01/31 00:00:00" in Answer!!!
It almost seems as if a derived logical column is cached in some weird way and changes to the formula is not reflecting in answers. Thinking that something so simple must work and I made a simple mistake somewhere I have spend a good part of the past day playing around with this and trying every possible solution I can think of - no luck. The odd thing is that I would rename my logical column and this will be reflected in Answers, but changes to the derived expression is not reflected.
- I deleted the column and started all over - no luck
- tried creating derived columns using different datetime expressions or even just concatenating strings to each other - no luck.
- Restarted all the Oracle services, thinking it's a cach'ing issue - no luck.
- I rebooted the server - no luck.
Once, when I started out with only MONTHNAME(Sales.OPPORTUNITY.ESTIMATEDCLOSE) I got back correct values in Answers (Jan, Feb, Mar..) and I thought the problem was finally gone. So I added || ' - ' || CAST(Year(Sales.OPPORTUNITY.ESTIMATEDCLOSE) AS CHAR(4)) to the derived formula. Guess what, Answers kept on giving me back only the Month names, completely ignoring my updated formula.
Anybody else ran into this problem? Something so simple should surely work...

John,
Yes, cleared the cache (from Dashboard Administration) and also used nqcmd Call SAPurgeAllCache. Restarted BI Server. Still no luck.
I tried your formula and then only got back "2008/01/31" (just the date without the timestamp) - very strange.
Then I noticed the following amazing thing (by accident):
I started with a request in Answers that does not contain my derived column and then add my derived column to the report. The text would be all wrong in this column (Jan, Feb, March). Then I add the same column again to the report and the second added column will magically show the correct strings (Jan - 2008) !!! Even stranger is that the moment I added the same column again to the report, the text on the first column would also magically jump to the correct values (Jan - 2008).
I did a bit more testing and created a blank request and added my derived column as the only column - this time it will show the correct values immediately. It does seem like it's tied to the content already in the request. I went a step further and saved my buggy request and added it to a Dashboard - it worked perfectly in the Dashboard.
Must be something buggy here in Answers when working with derived columns. I'm on 10.1.3.4...

BMM derived logical column - bounced visit

In Web Metrics, a "bounced visit" is when a session views only one page on a website and then leaves. In my fact table, I capture the "total pages" viewed for each session and I define this metric in my Business Model with an aggregation rule of "sum". I'm trying to use this metric to derive the "bounced visit" metric but I'm running into issues.
Session ID Total Pages
1179860475     5
1179861625     1 <= This is a bounced visit
1179861920     7
1179866260     2
1179868693     13
If I define "bounced visits" as
CASE WHEN "total pages" = 1 THEN 1 ELSE 0 END
What I see in the session logs is:
CASE WHEN sum("total pages") = 1 THEN 1 ELSE 0 END
The aggregation of the "total pages" is being done first and then the derived metric is being calculated. This leads to incorrect results. Is there anyway of solving this in the business model? I know that I can go back to the ETL, calculate a "bounce visit" metric, store it in the fact, build out aggregates, etc. I was looking for a short term solution.
Other things I've tried:
1) make a copy of the "total pages" column and turning off the aggregation, call it "total pages - no aggregation"
this leads to queries of the form:
select distinct T22583.TOTAL_PAGES as c1
from
WEB_SESSIONS_A1 T22583
order by c1
2) Create a logical column based on "total pages - no aggregation"
bounced visit = CASE WHEN EnterpriseWarehouse."Web Sessions"."Total Pages - no aggregation" = 1 THEN 1 ELSE 0 END
This leads to [nQSError: 14020] None of the fact tables are compatible with the query request Web Sessions.bounced visit.

Cool. I now have two approaches to solve the problem. Thanks for your help. Using your technique, the new logical column shows up in the Logical Table Source screen and I can define an expression for that logical column. The second approach leaves the table type as a Physical table. This has some benefits as I've noticed that the queries that are generated when the table type is defined as a Select statement end up retrieving all of the columns, even though I only needed to act on one of them.

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.

Thank U

Hi...
if avg sales should be calculated to current month always.. then why don't you apply external filter ..
i hope you are having time dimension columns like: year and month which is holding values like 2010, 2009.. etc, and 1,2,3,4.. etc..
If then,
apply this filter..
Year = Current_Date
and
MonthNumber = Month(Current_Date)
you can't include those 2 r.h.s values directly..
click on filter option of year column then > Advance > convert this filter to SQL.

URGENT: Paradox "Logical" Column Lost in HS translation to Oracle 8.1.7.3

I have a Paradox table with several fields. One field is a Logical Column.

Please check what the logical ODBC datatype this logical column is translated to and verify if Generic Connectivity supports that datatype or not.
I believe it converts to SQL BIT and Generic Connectivity does not support this datatype.
The datatypes that we support are listed in Chap 7 of the Heterogeneous Connectivity Administrator's Guide.

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

Create a logical column with more than one data source

I'm having a problem to create a logical column with more than one data source in Siebel 7.8.
What I want to do is the union of 2 physical tables in one logical table.
For example, I have a "local_clients" table and a "abroad_clients" table. What I want is to have a logical table "clients" with the client data from the 2 tables.
What I've tried is dragging the datasources I need onto the logical column.
However this isn't working because it only retrieves the data from the first data source.

Hi!
I think it is not possible to do this just by dragging the columns to the logical table. A logical table can have more than one source, but I think each column must have just one direct source column.
I'm not sure, but maybe you should do the UNION SQL to get the data of the two tables. In the physical layer, when you create a new physical table, it's possible to set the "table type" as a "SELECT". I didn't try that, but it seems that it's possible to have the union table in the physical layer.
Bye.
