OLAPTRAIN - Measure Aggregation Problem

Hi all,
i've a great problem and i ask your help.
I've installed OLAPTRAIN schema and I've correctly generated repository file thru AWM plugin.
Once uploaded repository i've tried to make analysis with BIEE.
I've choosen Region as dimesion and Sell as misure but here i've the problem.
Here is an example of result:
Region Sell
Africa
123
456
789
123
Europe 565
575
342
As you can see, Region is correct but Sell is not aggregated correcly while in AWM data are all correct.
I've also tried to chose only dimension and they are correct.
Example:
Region Product Channel
Europe Computer Direct
Camera Direct
Indirect
So i think the problem is with Sales table facts.
Could you help me to find the problem?
Aplication Versions:
oracle BIEE 11.1.1.5.0
Administration TOOLS 11.1.1.5.0
AWM patch 11.2.0.2.0B
Thank you all very much in advance.

It could be a problem with versions compatibility?

Nested Aggregation Problem

I am using OBI 11g.
Nested aggregation is not supported in some forms in the BI Server (RPD), but appears to be possible by putting the second aggr rule in an Answers column formula or pivot view column. However, I cannot get this to work. Looks like can even be done in the RPD with aggregation based on dimensions, as long as there is a standard aggregation function on the outside of the expression.
The biggest problem with any of the above techniques is the BI Server does not push the outer aggregation rule to the DB engine (the generated SQL).
In my case, consider a Referral Fact with Customer Dim and Referral Dim. I need to get # of Referrals per customer, filter that with a case statement to "bin" 1 Referral and >1 Referral, and then get # of Customers in each bin. So the first measure aggregation looks like:
Other: COUNT (DISTINCT "Referral Key")
Customer: "SUM( CASE WHEN "Referral Key" = 1 THEN 1 ELSE 0 END )"
Or the logical measure just has the COUNT DISTINCT aggregation rule and an Answers column has the CASE statement with a SUM aggregation rule. Or use CASE WHEN "Referral Key" = 1 THEN "Customer Key" END and use COUNT DISTINCT instead of SUM.
All these appear to return correct results, but they all perform the outer aggregation in the BI Server or Pivot engine instead of pushing to the generated SQL (DB engine).
I can't find any problem in the DB Features. We are using SQL Server 2010.
Thanks in advance for help.

Hi AL,
here is my requirement what i have been asked to get this output result.
i have keyfigures KF1, KF2 and total KF.
three characteristics dist,inch,load.
dist-inch-load--KF1-KF2-Total KF
5---A--010-0-----10=10
5---A--120-20----20+10=30
10--B---050-0-----50
12--C---160-60----60
13--D---270-70----70
14--E---080-0-----80
15--E---120-20----20+80=100
15--E---230-30----302080=130
KF1 is the initial volume coming from the file directily.based on this keyfigure i have to calculate KF2,Total KF.
In order to calcuate KF2 and Total KF i have some conditions.which are mentioned below;
KF2---> if load=0 then KF2=0 elseif load>0 then KF2=KF1 ;
Total KF--->if load=0 then Total KF=KF2KF1 elseif load>0 then KF2=KF2KF1
How to achieve this dynamic summation.Do i have to do nested exception aggregation based on the above three characteristics. what would be the open options.please do help me.

Measure Aggregated at Logical Level causes poor performance

OBIEE 11g
We've recently implemented a new measure which involves aggregating a Period expenditure figure up to the Fiscal Year level.
I've duplicated the existing Period_Expenditure rename to FY_Expenditure, and then changed the logical level for the Time dimension to Fiscal Year.
I get the figures I expected, however the OBI SQL generated wasn't what I expected.
We now have the main SQL as before but now its left outer joining to a 2nd SQL statement that does the aggregation, which is pretty expensive in terms of Logical IO. Elapsed time going from 2 seconds to 20 seconds.
I would have expected the BI server to be clever enough to apply analytics to solve this problem - has anyone else had similar issues when using aggregates like this?
Thanks in advance,
Matt

I'm going to answer my own question here as I've managed to build a simplified solution, it may help others.
Basically the Analyses this is running for is:
select measures, FY_Measure
from fact_table
where period = 'MMYYYY';
Because we don't have the full set of data within this SQL to enable coverage for the FY_Measure (ie. we're at period level granularity) OBIEE is smart enough to create a 2nd query to get the data required for the year.
If we change the analyses to be:
select measures, FY_Measure
from fact_table
where FY = '2012';
It will quite happily create analytics to satisfy the measure - fairly straightforward really.

First time to build OLAP Cube - aggregation problem

I am new to OLAP technology and i want to build first OLAP cube. i use scott schema doing:
1- build dimension on "DEPT" table with one level deptno.
2- build cube with one measure sal on "EMP" table.
Table Emp
DEPTNO     SAL
20     800
30           1600
30          1250
20          2975
30          1250
30          2850
10          2450
20          3000
10          5000
30          1500
20          1100
30          950
20          3000
10          1300
table DEPt
DEPTNO     DNAME
10          ACCOUNTING
20          RESEARCH
30          SALES
40          OPERATIONS
when i use maintain wizard and then view data the sum of salary is not accurate it looks like
sum
all depts 5550
accounting 1300
researches. 3000
sales 1250
operations 0
values should be
sum
all depts 29025
accounting 8750
researches. 10875
sales 9400
operations 0
why the aggregation values for departments is no accurate??

Problem is visible in your below table.
Table Emp
DEPTNO SAL
20 800
30 1600
30 1250
20 2975
30 1250
30 2850
10 2450
20 3000
10 5000
30 1500
20 1100
30 950
20 3000
10 1300
There are multiple of dept no with different sal. In OLAP when you load such record then the last record comes wins. This is why if you observe then you will see the value you see is the last value getting loaded.
To resolve this you should do a group by (in emp) deptno and sum(sal). Load the records and you will see correct result.
Hope this helps.
Thanks,

Aggregation problem in Qery design

Hi folks,
I have the following situation:
- Characteristics as line items, shown as a hierarchie.
- KFs and Formulars in columns
I want the formulars to be calculated on the basis of a combination of two of the characteristics (the bottom two in the lines hierarchy) and then aggregated.
Exception aggregation allows me to choose "total" based on one characteristic, but not a combination of two.
One solution would be, of course, to create a new characteristic in the cube that is a combination of the two existing characteristics in question and then use this for exception aggregation. This would be a bit complicated though, as the two characteristics are in fact navigational attributes of characteristics that appear in the data source and the cube.
Therefore, I'd prefer a solution that is in the scope of query designer rather than cube design.
Any ideas?
PS: The formulars show correct values on the level of the bottom most characteristic in the lines hierarchy if I choose that characteristic for exception aggregation. The results are not correct one level up from there as I can not get the system to sum the results up along the hierarchy. Instead, they are calculated for the aggregated values of the KFs used in the formular.
Apparently the "show lines as hierarchy" function really only affects display of the lines, not calculations.

Hi John,
I understood your problem. Solution is easy:
Make formula 1, exception aggregation as total , ref char as char 1
Then make another formula 2 on formula 1, exception aggregation as total , ref char as char 2.
And in the report show formula 2 and hide formula 1.
Best Wishes,
Mayank

CostCenter Group Aggregation problem. High Priority Issue.

Hi Experts,
I have very crital issue in the report, Help needed.
   I had some kind of requirement in one of the Overhead cost report, need to combine the COPA data and Costcenter(Over Head cost) data. I have a problem with Costcenter Group aggregation on the report.
I have Restricted 2-Keyfigures want to derive the 3rd Keyfigure values. I given the below exmaple of the data. In my report I just want to display the KeyFigure(KF-A,B,C). I dont want to Display the Cost Center group/Costcenter Number in my report. My report ouput will be one line. But If I removed the costcenter Group I am seeing different values of the Keyfigure C, If I display the Costcenter comng with differnt Values. I am expecting the values in the column C is 1400 but it is coming like 3600.
Please guide me how to design the Keyfigures if I want to get the value 1400 in theKeyFigre C with out Showing the Costcenter In the report.
Cost-Center Group R00048
                  Costcenter     KF-A     KF-B           KF-C

Read from measurement file problem

Hi all,
I am using the "Read from Measurement File" VI that is built into LV8. I am reading in a .lvm file consisting of 2 columns. I cannot seem to figure out how to index each column. When tested using a a single column data file, I am able to use the index array vi to access the data successfully. The problem occurs when I have 2 columns. To get around this problem I split my initial data file into 2 single column data file, but I would prefer not having to do this. Is there anyway to avoid this?
When I read the 2D file into an array I can only index the data located in the 1st row 1st col and the data in the last row 2nd col.
The array size function results in the value "2" yet each column has 201 entries.

Measurement & Automation Problem I think?

Hello, have two seperate computers running the same software, one has vb6 installed.
I have a labview program and vb6 program that does pretty close to the same thing.
I set up a task in M&A with 2 temperatures. Voltages are the problem.
They run fine in vb6 with a voltage of around .25 on one computer.
I switch the usb cable of a daqpad6015 and the voltages changed to .14 and .09 on the other computer inside m&a and labview.
I am also taking 2 pressure and flows in the same task which have equivelent voltages between computers.
Whats happening.
thanks.
The funny thing is if I unplug the usb cable and then plug it back in, the correct voltage is displayed in m&A for a split second and then drops to the errored voltage.

Hi Jes,
I just want to make sure I understand the situation: You have a single DAQPad-6015 for USB with two different cables, and you are connecting it to different computers (only one at a time, back and forth). You have a VB6 program on one computer and a LabVIEW program on the other computer, each performing the same tasks. This task is comprised of 2 AI Temperature channels, 2 AI Pressure channels, and 1 AI Flow channel. When reading from the VB6 computer with cable #1, you read .25V on temperature channel 1. When reading from the LabVIEW computer with cable #2, you read .14V on temperature channel 1. Is that correct?
I would suggest reading from Measurement & Automation explorer on both computers from the DAQPad-6015 with cable #1, then doing the same thing (reading from Measurement & Automation explorer on both computers from the DAQPad-6015), but this time with cable #2. This will eliminate the variable of the software application being used. If both cables are working properly, you should see the same readings on each computer. If they are different, it sounds like one of the cables could be faulty.
Also note that if you are taking temperature readings, slight variations in temperature will cause changes in the voltage read in. So if these computers are in different rooms, the difference in reading could be due to the difference in temperature between rooms.
Please verify that I understand your setup and give that a try. Let me know if you are still having trouble...

Aggregation problem

Hi experts.
I've got 3 tables A, B and C.
Columns in A: "Konto", "Klient", "Saldo"
Columns in B: "Konto", "Klient", "Rach", "Saldo"
Columns in C: "Konto", "Rach", "Kwota"
Physical diagram A -<-B ->- C
Business model diagram A -<- B ->- C
Logical table source: A for table A, B for table B and C for table C.
I add logical table source C to table B, and add one column "Suma Kwota" with aggregation rule: sum.
Know when i create report with columns
C."Konto", B."Suma Kwota"
everything works ok, but when i add column from table A or B for example
B."Klient", C."Konto" , B."Suma Kwota"
then column "Suma Kwota" return null values for all report.
Why have i null values?
Next I add table B to logical source of table C, so i have table C and B in LTS C using inner join. Know on report column B."Suma Kwota" is not null but return bad values (too high). I have joined table B and C through the columns "Konto" and "Rach".
In table C i have distinct values for column "Klient" but in table B not. So for example when i have one row for "Klient" in C then i can have 10 rows for that same "Klient" in table B. So when i have one row for table C and 10 rows for B then "Suma Kwota" is 10 time bigger.
How can I avoid this?
I can use not aggregated column "Kwota" from table C and use sum in the presentation service but i want to know why this is not working with measure.

Unit of measure language problem

Hi experts,
I'm selecting matnr and meins from MARA. In SE11 I see the meins in my language (DB), but when I'm executing my program than I see the Unit of measure as 'ST' (Stück).
Could you help me in how can I get the unit of measure in a certain language?

Wenonah that won't work since the meins in MARA cannot be found in T006.
But finally I found a function module which solves my problem:
CONVERSION_EXIT_CUNIT_OUTPUT

SQL: Aggregating Problem

Hello,
i have following problem with aggregating values with one of our tables:
For each day there is a row which contains the change to the previous day.We need now a view containing for each date of the year a subtotal from the beginning of the year . Is there any aggregating function with this functionality? Is it possible to solve this without using PL/SQL?
Example:
create table example (datum date, diff number);
Rows in the table:
insert into example (to_date('01-01-2005','dd-mm-yyyy'), -1);
insert into example (to_date('02-01-2005','dd-mm-yyyy'),1);
insert into example (to_date('03-01-2005','dd-mm-yyyy'),2);
insert into example (to_date('04-01-2005','dd-mm-yyyy'), -1);
We need following result:
'01-01-2005', -1 --(sum from 01-01-2005 to 01-01-2005)
'02-01-2005', 0 --(sum from 01-01-2005 to 02-01-2005)
'03-01-2005', 2 --(sum from 01-01-2005 to 03-01-2005)
'04-01-2005', 1 --(sum from 01-01-2005 to 04-01-2005)
Thanks for your help

Aggregator Problems

I have three swfs/projects that are daisy chained and also put into the aggregator. The aggregated file is here.
When it gets to the end of one swf and starts the next, instead of showing the next swf correctly, it plays the audio only for a few seconds while showing a white screen and then stalls out. At that point, the controls for the movie no longer work. It looks like this when it stalls:
This behavior is the same whether the files/projects are daisy chained or not. It also did it when I used a button to launch the next file.
If I refresh the browser when it is stuck, it starts working again, but the TOC controls no longer work. You can click on a TOC entry and nothing happens.
I routinely clear the browser and flash caches when I test.
I am struggling to get the project titles to save correctly, have tried most of the save as tricks suggested here. Don't know if that is part of the problem, but suspect it is not, because the file starts playing again correctly when refreshed. Also deleted the Adobe Captivate Course Companion widget in the swf that stalls out (the only plugin), but that didn't help.
Been working all day on this one, would love some fresh ideas. Thank you!

When publishing projects that will be aggregated, don't try to daisy chain them. Aggregator will look after that. Just set the Project End option in Preferences to Stop Project. After each SWF is aggregated, as soon as one project finishes playing, the next one will start.
Another tip I find useful: Don't have any objects on the very first slide in each SWF. Just make it blank and about 1 second long. Start your animation or audio etc on the second or third slide in the movie. If you want a fade-in effect, use the first blank slide as a fade in slide via the Project Start option, not the slide's own fade-in transition. The project fade in seems cleaner to me.

In DWH you will be loading data at leaf level and OLAP engine does aggregation(solve) and store data at higher level. What you are seeing is correct as any node's value is equal to the sum of values of its children.

Streaming data and writing data to measurement file problem

Hi everyone,
I found something wrong about my code but i don't know exactly what it is first i have a program for acquiring 15 analog signals(NI PXI6259) after acquiring the data i use network stream to stream data from my NI PXI8186 to the host pc these steps are in target VI, after streaming data to host PC
, i tried to write down the data to the spreadsheet using Express write to measurement VI.
Problems : 1. After i run the host Vi and target Vi the number available to read is always 0 after sometimes the data displaying on the chart incdicator on host Vi is stopped and start counting the numberavailable to read also the time indicated on X axis of the chart doesn't grow.
2. Write to measurement file generate the file that record the data counting the data from 0 to 99 and start over and over again
Please help i really have no idea what is the cause for each problems.

sometimes the target (NI pxi8186) will reboot itself and displaying message "Reboot due to system error" "System state: Safe Mode (System error)
and on the Host PC there will be a window pop-up displaying
"Waiting for the target (NI-PXI8186-2F0a597C) to respond" "Stop Waiting and Disconnect"
i didn't run the host Vi just run the target Vi only. If this problem caused from the program or the hardware ? Please help.

OLAPTRAIN schema installation problem

Hi,
I am trying to create OLAPTRAIN schema but it hangs when trying to import dump file. I am not sure how long it takes to import the file. I am running the script from toad. After 20 minutes nothing happens. looks like toad is hanged, not sure it is still running in the background. I have already install awm and created the connection successfully.
can you please guide?
Thanks,

It could be a problem with versions compatibility?
