How to create Analysis from two different subject areas with diff models

Hello,
I have problem with create analysis from two different areas with two different models (Model Star and Snowflakes) build in BI Admin tools.
First Model A = Subject Area A have one fact tables (with measures) and three dimensions tables (Model Star)
Second Model B = Subject Area B have one fact table (no measures) and five dimensions tables (Model Snowflakes).
I'm looking solutions how I can give good results. In this case I can't use UNION, INTERSECT etc., because this models haven't the same number column and data type?
whether it is possible to do in OBIEE?
Please help me
Kind regard
robix

Hi
One thing to understand is that if your are imagining having two Subject Areas (SAs) displayed and then dragging columns from each into your Request without any preparation, then no, that can't be done. You would need to do a join in the BMM layer and expose the column from the second Subject Area in the presentation layer.
But if you indeed interested in UNION (or intersect) queries, then do this:
Build your first query in the first SA in the usual manner. Note the number of columns and the data types of each column.
Now at the bottom of the Criteria workspace, there is a button called "Combine with similar request." Click it.
Select your second SA. You will note that the outlines of the columns in your first query appear. This is to remind you that the number of columns in this second query must be the same as in the first. It also shows the data type of each column for the same reason.
Once you select your columns and your filters, click on result. (Oh, you will also need to decide what kind of combination you want -- click on the dropdown.) The result will be a new Request that has data from both SAs in the query and combined in the manner you select (union, intersect, etc.)
That should give you a start.

Error when building a report from 2 different subject areas

Hello Experts,
I am using obiee 11.1.1.5.
I have 5 dimension D1,D2,D3,D4,D5 connected to fact1 and 4 dimension connected to fact2 such as D1,D2,D6,D7.
where D1,D2 is common to both the facts.
Fact1 Is in subject area 1 and Fact2 is in subject area2.
I need to create a report by adding columns of subject area 1 and 2 with columns from all the dimensions D1,D2....D7.
As of now i am getting error stating "No fact table exists at the requested level of detail " when i try to add columns from 2 different subject areas.
Can anyone help me in solving the above problem.
Is there any prerequisite to be taken care when building a report from 2 different subject areas.
Regards,
NN

Hello Nagireddy,
So kind of you, for your quick reply
I was able to solve the error by doing below steps in additional what you have specified
-->For the fact table LTSs, set the logical level in the Content tab to the dimension's lowest level for each conforming dimension (leave the non-conforming dimensions level blank).
Now I have another requirement i,e
I need to have non measure columns such as Date into the newly created fact in BMM layer.
I tried doing the steps which I followed for measure column, but it is throwing the same error which I get earlier.
Below is the error
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 14025] No fact table exists at the requested level of detail:
Let me know if have any suggestions

How to calculate AGE from two different date fields

hi
I need to calculate AGE from two different date fields.
Can some help me how to do, when i try to do substraction formula it is showing error.
Thank You
Manu

Manu wrote:
Hi
Both fields are in date format only, i need to calculate no . of days between two different dates
Thanks
ManuThe reason for the question about the format of the column is because the simplest solution only works on DATE columns. Others have mentioned this here, but if you want the difference between two date fields, you can use this formula:
TIMESTAMPDIFF(SQL_TSI_DAY, date_column1, date_column2)
The above being said, you still didn't tell me what you did, or what error message you received. So again, if the above formula didn't work, what did you do? Where did you put the formula? What was the exact syntax you used? What was the error message you got?
Please don't make us work more than we need to. Answer all the questions in your next post. Thanks.

Fields from 2 different Subject Area via inner or outer join

Hi All
I have a requirement where I have to pull columns which are available in 2 different Subject Areas.
For eg. Col1 and Col2 in one SubjectArea1/Report1 and Col2 and Col3(obviously not available in SubjectArea1) in second SubjectArea2/Report2.
The resultant expected is a single report with Col1, Col2 and Col3.
SUBJECTAREA1/REPORT1---- SUBJECTAREA2/REPORT2----------- FINAL REPORT(on Inner/Outer join)
col1,col2----------------------------col2,col3-----------------------------------col1,col2,col3
Please let me know how to achieve this

Outter Joins are not available within On Demand. Please let me know what Objects you are trying to user here for SubjectArea One and SubjectArea Two?

How to sync files from two different subscriptions in two different CC desktop folders

HI,
I have two CC subscriptions, one for work and one personal. I ran the work subscription in two computers at work and at home (when I need to work from home.) The problem I find is that there is not two different CC folders for each subscription. When I log out from my work subscription, all my files for that subscription go away. Then when I log in again, they whole syncing process starts all over again. I chose to have two different subscriptions so not to mix my personal work with my work's. Is there a way to have a CC folder on my desktop for each subscription? In this way, when I log out from one account and go to the other the files of the account I just logged out don't get replaced for the files of the account I just logged in. Any help with this will be greatly appreciated.

Hi,
I just want to let you know what you should be seeing when using 2 accounts.
Account one:
1. Log in with Adobe ID for account one
2. Files sync to Creative Cloud files which is located in your home directory on Mac or Windows.
3. Log out of account one, Creative Cloud now displays the log in panel.
Account two:
1. Log in with Adobe ID for account two
2. Files sync to account 2's Creative Cloud files which is located in your home directory on Mac or Windows. (Account one's Creative Cloud Files folder is re named)
Thing to check for are:
After you logged in to account two, the Creative Cloud folder for account 1 should now be renamed, can you check this please to make sure it has.
The same is true is you log back in to account one, account two's Creative Cloud folder will be renamed.
The data should not have to fully re-sync ever time you log out of account 1 and then into account 2, however, can you be sure that the data is actually re downloading. ie; you had 5GB of data in account one and when you log into account 1 the whole 5GB of data is re downloading?, could you check this?
The Creative Cloud files panel will display "Syncing" for a short while is you switch accounts, this is normal and means the application is reading data on disk and data on the server checking for changes/added files etc. This is not re-downloading all of your data, it is simply checking.
You are able to move the Creative Cloud files folder to any location on your local hard drive via the Creative Cloud prefs.
Thanks

HT201272 How can i download from two different accounts without the 90 day rule?

I have two Apple IDs because I had lost the other one and made a new one. I recently bought a new computer and went I also found my old password for my first ID.

How to handle transactions when two different databases are involved.

consider two tables namely Table-A and Table-B part of two different databases namely ORACLE and MYSQL.
Now the project requirement is updating the Table-A(ORACLE) and Table-B (MYSQL) as one transaction. i.e. either update both the tables or rollback both the tables.
Now my question is how could i handle this situation using JDBC(Type-4) driver.Because i think at a time only one JDBC driver can be loaded into the JVM.

But anyway, you need to use distributed (XA) transactions. i believe that the latest version (5.0) of mysql actually has support for XA transactions. you need to use a to setup a distributed transaction and attach the connections for the two databases to that transaction. then it should function as you desire.

How to superimpose data from two different charts into a single chart?

I have a single chart that lists numbers by month for a two year period like this:
Jan 100
Feb 200
Jan 103
Feb 199
The numbers are all in the same column rather than different columns.
I'd like to creat a chart that plots the data for each year on the same X axis, so that I can see the two january numbers, the two february numbers, etc. on top of each other. But nothing I've tried seems to work. Numbers seems to always put the second january after the first december on the x axis rather than recognizing it as a new series to be superimposed on top of the original january.
Is there some way to fix this short of putting the data into a new column?

What your describing is a table of wht I would call raw data. I would also have a summary table that would use functions like sumif and sumifs, then make my chart off that. This table would have each month in a column and the years across as headers. ( if you're familiar with excel, it would be the equivalent of making a pivot table and chart, but manually).

How to compare signals from two different .tdms files?

i'm developing a lie detection system in labview.so inorder for that i need to compare the threshold physiological signals from the .tdms file with the signals i acquire continuelsy from the subject for each question asked.i use respiration monitor and heart beat monitor together with the sensorDAQ to acuire the physiological signals.so which are the function i should make use of?i have the following toolkits
1. advanced signal processing toolkit
2. adaptive filter toolkit
3. digital filter design toolkit
4. biomedical toolkit
please give me advise on this.
thank you.
Solved!
Go to Solution.

Lie detector systems (polygraphs) generally work by looking at the physiological responses to the own subjects baseline, and do this in real-time. You could use a file that represents the stored "baseline" for the subject, but the overall environment, circumstances, general state of the subject, etc. may not be similar enough to easily see subtle changes.
From the stored file, you might determine a set of parameters or thresholds that indicate "normal, relaxed" for each signal. You could read the file into your LabVIEW program, process each channel, and save these parameters. Then when you have the new data, you can read the new data file in and process it in a similar way and then determine whether the parameters are outside the limits that you established for a "lie".

How do I XY graph two different signals each with its own y-axis on the same graph?

I have wired an n-ch, 1 sample VI to an xy graph express VI. I have two y-axis scales, but I only see a plot of one of the signals. Can anyone help me understand what I am doing wrong, and how to do it correctly? The VI as a whole may look ugly, but the flow of the signal from the xy-graph is obvious (but not working the way I want it to...). My sub-VI is attached. Thanks in advance, Christian

Hi Christian,
That express VI requires that you input an X data set for each plot.
If you must use that express VI, then for your program you need to insert a "build array" function, with two (or more) inputs, in line with the express VI's "X input", and wire your X data array to each of the build array function's inputs - see the example I've attached.
Personaly, I wouldn't use the express VI at all - it really isn't difficult to manipulate your data into the right format for the XY graph using simple functions - see the second example I've attached.

P.S. Gotta be worth about 6 stars I reckon!

How do I purchase from a different iTunes store with the same Apple ID ?

I'm registered with the Australian iTunes store but the song I want is available only on the Norwegian iTunes store.
Clicking the iTunes track link from the artist's website prompts me to change to the Norwegian store, but after I do that and try to download the song it tells me that the logon details are valid only for the Australian store and invites me to register for the Norwegian one.
So, I go through the registration process for the Norwegian store only to be advised by iTunes at the last minute that "The email address you entered is already being used for an Apple Account. If it is yours, you can cancel and Sign In using that Apple Account", which of course contradicts what it told me earlier.
iTunes tests my patience at the best of times, but this seems to be deliberately and unnecessarily complex - I have an Apple ID and they have already got my payment details so what is the problem ?

This is crazy. So instead of the artist getting my 12.00Kr payment for the track, the only choice I have is to acquire it by unofficial means - it's not released here and probably never will be.
Thanks for the replies.

How to create a foreign key for the table from two different tables?

Hi All,
I have a three table like below. In the below table SAMPLE_CONS_CHECK and SAMPLE_CONS2_CHECK will be having the primary key for NAME column. The same SAMPLE_CONS3_CHECK table also having the primary key for NAME column and forieign key for SAMPLE_CONS_CHECK and SAMPLE_CONS2_CHECK tables. See the below code 2
code 1:
CREATE TABLE SAMPLE_CONS_CHECK
        (NAME VARCHAR2(10),
        SERIES VARCHAR2(5)
CREATE TABLE SAMPLE_CONS2_CHECK
        (NAME VARCHAR2(5),
         MODEL NUMBER
CREATE TABLE SAMPLE_CONS3_CHECK
        (NAME VARCHAR2(5),
         MODEL_NO NUMBER
        )code 2
alter table SAMPLE_CONS_CHECK
add constraint SAMPLE_CONS_CHECK_pk primary key (NAME)
alter table SAMPLE_CONS2_CHECK
add constraint SAMPLE_CONS2_CHECK_pk primary key (NAME)
alter table SAMPLE_CONS3_CHECK
add constraint SAMPLE_CONS3_CHECK_pk primary key (NAME)
ALTER TABLE SAMPLE_CONS3_CHECK ADD
CONSTRAINT SAMPLE_CONS3_CHECK_FK1 FOREIGN KEY
     NAME
) REFERENCES SAMPLE_CONS_CHECK
    NAME
) ON DELETE CASCADE;
ALTER TABLE SAMPLE_CONS3_CHECK ADD
CONSTRAINT SAMPLE_CONS3_CHECK_FK2 FOREIGN KEY
     NAME
) REFERENCES SAMPLE_CONS2_CHECK
    NAME
) ON DELETE CASCADE;From the above schenario i am able to insert the data to SAMPLE_CONS3_CHECK table. But the parent data is already available in the parent table. The problem is here two different constarints from two different tables. While inserting, it is checking from both the tables whether the parent is exist or not.
How can i solve this problem? Can anyone halp me about this?
Thanks

Actually the design is completely incorrect.
What you say is
I have
'foo', 'foo series'
'foo','foo model'
'foo',666
By virtue of table3 referring to both table1 and table2.
This means you actually need to have 1 (one) table:
'foo','foo series','foo model', 666
And the 'problem' disappears.
