Semi-additive measure using specified time dimension

Hi,
I am trying to make a semi-additive measure which will represent an Order Intake calculation. Please see the data below:
I plan on taking a copy of my Open Orders (Order Book) on the 1st of each month. This gives me the ability to show that for example order A was entered in january, but at some point during the month it was increased by a value of 5. So if I use
Order_No and Value i see the following - which is good:
ORDER NO
Value
A
15
B
20
C
25
D
10
Using snapshot_date as below, is good:
Date
Value
2014-01-01
30
2014-02-01
50
However, using Brand i see the following:
Brand
Value
X
15
Y
35
What I don't understand is why the value in X is wrong, but Y is right? I am expecting the sum of the different orders within the brand, but the latest value by snapshot date.
The "Value" is using the AggregateFunction "LastNonEmpty".
I hope this example makes sense and look forward to some responses!
Thanks

Semi additive Measures across non time dimensions

Hello,
I need to make my measure semi additive across a non time dimension (Since I am getting totals at each level and I cant roll up the children to the parent, instead create a dummy member at the lower level for total and use FirstChild). Is it advisable to change the dimension type to time to achieve this functionality?
Thanks
Arun

I had followed exactly the same approach specified in the paper without using parent child dimensions. I had created "blank" members instead of the same name as the parent member. Now, the issue is, I have to make the measure's aggregation as "FirstChild" so that it takes the "blank" member's value for the parent.
Another issue is, I have multiple dimensions in the cube and I have aggregated data across dimensions in my source. For Example,
Col1                                                          Col2
Dimension A Level1 Member1           Dimension B Level 1 Member 1           1000
Dimension A Level1 Member1           Dimension B Level 2 Member 1           500
Dimension A Level1 Member1           Dimension B Level 2 Member 2           500
Dimension A Level2 Member1           Dimension B Level 1 Member 1           2000
Dimension A Level2 Member1           Dimension B Level 2 Member 1           1000
Dimension A Level2 Member1           Dimension B Level 2 Member 2           1000
Thanks

Semi additive measures

Hi, I need to create a semi additive measure in the bussiness model using the LAST function over the time dimension...
In the aggregation tab I set Dimension Time with the LAST(), and Other with sum... when I use the measure in answer I get nothing...
I try putting the LAST aggregate function over the SUM aggregate function in the aggregate tab....
How should I use this feature?
Thansk

Hi,
I'm not quite sure, but don't you need to create a level beased measure on time level and the last function over your measure?
So duplicate the measure you need, put aggregation level on last and set the dimension level to the corresponding time level.
Otherwise try to explain once what you want to achieve...
Hope it can help you.

Additional custom level on Time dimension ?

Hi,
I´m very new to OWB, so I don't know if what I want to do is even possible at all.
I created a time dimension using the "Time Dimension Wizard", selecting all possible levels (year, quarter, month, day), but I also need to have one extra level: semester. You see, we need that level for our reports.
I tried to open the mappings that were generated automatically but Oh, boy! does that look complicated!!! Some operators call time functions but when looking them up, they're in packages that come wrapped, so basically I have no clue as to how the data is being generated by Oracle.
Do you know of any way to accomplish this? Basically have a time dimension with the levels:
Year -> Semester -> Quarter -> Month -> Day
Any help would be very much appreciated.

Hi JP,
Thanks for the tip.
I created a new "time" dimension manually. I basically made a copy of the attributes and levels of a normal time dimension, plus the new fields for "semester". I also defined the corresponding fields for "END DATE" and "TIME SPAN".
Now, I can populate this dimension, based on a script that someone else posted in this forum. I'm not sure, though, that Oracle OLAP will recognize this as a "time" dimension, will it? I mean, OWB adds some extra fields for a time dimension created with the wizard (like "level type"). Will this affect the performance or behavior of my cubes? Or, can I say that this is as real a time dimension as one created with the wizard in OWB?
Again, thanks a lot for your support.

Additive/semi-additive measure HELP

I have a cube with dimensions TIME, GEOGRAPHY AND SALES_AGENT, built on a fact table that has
TIME_LEAVES,
GEOGRAPHY_LEAVES,
AGENT_LEAVES as FK's
and measures
SOLD_QUANTITY quantity of t-shirts sold
UNIT_PRICE the agent's price for one t-shirt
While SOLD_QUANTITY is fully additive, being SUM aggregated in the cube for all three dimensions, the UNIT_PRICE in totally non additive, so I let aggregation method to none for all dimensions.
Afterwards I made a calculation in JDev BIBeans multiplying UNIT_PRICE * SOLD_QUANTITY to get an income quantum, thinking it'll do something like (UNIT_PRICE1 * SOLD_QUANTITIY1) + (UNIT_PRICE2 * SOLD_QUANTITIY2) + ...
But the results go sky high, showing that it's not calculating the way I wanted it.
Do you have any idea? Is it possible to put a non additive measure with a fully additive one in the same cube? If so, how should I set the aggregation methods.

It's a relational cube.
Here is an example of a couple of rows in the fact table:
TIME GEOGRAPHY AGENT SOLD_QUANTITY UNIT_PRICE
========================================================
JAN04 LONDON AGENT1 240 20
JAN04 YORK AGENT1 123 20
JAN04 LONDON AGENT2 56 25
While sold quantity is fully SUM aggregable by all dimensions, the unit price is not (the cube shows NONE for all aggregations in OEM). Even so, the UNIT_PRICE add's itself on all three dimensions.
So instead of giving me a total income situation per agent of:
AGENT1 (240*20)+(123*20)
AGENT2 (56*25)
it returns something like
AGENT1 (240+123)*(20+20)
AGENT2 56*25

Oracle 11gR2 use the time dimension wizard---the cube didn't show any information!

I created a Time Dimension with the Time dimension wizard , a category dimension, and a rel_expense cube in OWB 。what I do is following the oracle 11g r1's turtoial
The rel_expense cube has two forigen keys, one is refrence the category dimension's dimension_key(primary key in the category dimension), and the other one refrence the time dimension's start_day_date(bussniess key in the time dimension).
The result I get is the rel_expense_tab had datas, but the rel_expense cube had nothing.
.I delete the category dimension , it is the same result(cube rel_expense had nothing).
But if I only delete the time dimension, it is ok(both of them had datas)!!!
So I think is the time dimension's problem ,because the 11g r2's time dimension wizard didnt' generate the dimension_key for time. Is the forigen key(time dimension) i refrenced in the cube is error,so if it is, what should I do?
SEEK FOR YOU HELP!!!!!
ps:my mother language isn't English ,so it has many erros in the passage

can anybody help me? the measures in my cube were round to integer, i doubt it came from time dimension. did anyone encounts such a senario

Specific request on how to model semi-additive measures

Hi,
I have a fact table with a "quantity" measure which is related to an "UoM" (unit of measure) dimension.
I cannot sum quantities that are not the same UoM.
Is there a way to instruct OBIEE (11g) not to sum quantities with different UoMs?
Note that all other dimensions in the fact table are additive.
Thanks in advance.

Of course I can. But the question here is different - how I can prevent users to aggregate quantity measure without grouping by UoM. That is, a user can have quantity measure in a BI analysis and "forget" to include UoM attribute to correctly group data - the result is that they aggregate peaces, kilos, etc all together. That's what is happening in real case with my users, they would like to have quantities correctly summed up.
Has anyone a suggestion on how to achieve this?
Thanks a lot,
Chris

Low-Frequency measurements using counter/timer

I am trying to measure speed, and am using the FP-502 counter timer module to count the pulses from my sensor. The field point example that uses a fixed width gate pulse will not work for my appliation because I need a gate pulse so big that it updates way to slow.
Does anybody have any sugestions on how to measure a low frequency signal using a counter/timer?
Thanks
Dan

Hello guys
Thanks for all your sugestions I have the final results. I got it to work but I would like to add some comments for anybody who is trying to attempt this.
Triggeing on the gate is a must for low frequency measurements. I used the divide by sugestion however using a factor of 3 only gets you about 60 Hz after that you can't sample fast enough. My application required me to measure from 0 to 150 Hz. I added a "gear shifter" routine where the terminal count was set to 3 on frequencies lower then 45 Hz and 15 for frequiencies greater than 45 Hz. Using a terminal count of 15 for all measurements made the udate rate on really low frequencies way to slow i.e. .5 seconds for 20Hz (check the math on this).
I a
lso needed to cascade the counters. At low frequencies the count went higher than 6550. Using the previos channel function of the fieldpoint module enable me to get 32 bit worth of terminal count data.
Finally I needed to add a timeout condition for 0 Hz. If there are no pulses coming from the senser the program displays the last value read. That won't be 0. So I added a time out routine that if I didn't see a pule in a certian amout of time, output 0 and reset the gate count.
Thank you for you help you relly saved me. I hope my comments made sense.

Semie addivie measure and strange behavour

Hi,
For the first time , I 'm facing a strange behavior with a semi additive measure.
In EXCEL when I' m crossing it with a product dimension (Declared as Regular type ... no time type),
the behavour is like we are crossing with a time dimension.
No SUM on the column , but the last non empty value whenever appear.
Product Type - Product code Cummulative Power
A 16 <-- Problem we don't see No 31
AA1 15
AA1 16
Total SUM 16 !! no 31
Does anyone have an idea about this problem ?
Thank you very much
Christophe

Hi Christophe,
your question is not clear to me. From what I understand your facing problem with measure 'Cummulative
Power' which uses aggregation function 'Last NonEmpty'.
Don't know whether this will help. In our case 'Last
NonEmpty' function would be calculating 'Cummulative Power' against 'Product' dimension attributes,
while the measure value being the value of highest member or last member of time\date dimension. (remember semi additive measures always requires time dimension)
For example consider the following table.
Product
Date
Cummulative Power
A
20140101
10
B
20140101
15
A
20140102
13
B
20140102
17
A
20140103
16
B
20140103
11
Here if 'Last NonEmpty' function is used with Cummulative Power then against each Product we would get the following results in cube.
Product
Last NomEmpty(Cummulative Power)
A
16
B
11
i.e. the above values are corresponding to the last member of time dimension (20140103) .

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

Composite key in Time dimension

Hi All,
I would like to know Time dimension with Composite key. I have a requirement where I want to store 2 Calendars in Time dimension table. for e.g :
for one calendar Weekstarts from SUN-SAT and for another it is from MON-TUE
DateKey Type WeekStart WeekEnd
20140101 1 Sun Sat
20140101 2 Mon Tue
..................etc
I have a measure group which is related to Time dimension (DateKey and Type used a Composite key). This implementation has no issues for additive measures but there are few issues with semi-additive measures (last non-empty,...).
Will composite Key have any effect on semi-additive measures ?
what if i use surrogate key instead of composite key.
Please suggest if the approach has any issue with Time intelligence. Advise if there is any better approach for the same.
Ram MSBI Developer

Hey.. Thanks!
I am clear about the concept about defining annotation based composite key. Also, I read in the documentation that I'll be needing to define as direct, aggregate or one-to-one. But, I am not able to define and run the same in the project mapping xml of toplink.
It would be great if you can share some sample code for defining the same. For e.g. in my mentioned example, there is TestEntity POJO having 'id' as the attribute which gets populated with the testEntityCode of the TestEntityKey POJO. Please suggest the same for the same:
<opm:primary-key>
<opm:attribute-name>id</opm:attribute-name>
<opm:field table="TEST_ENTITY_B" name="TEST_ENT_CODE" xsi:type="opm:column"/>
</opm:primary-key>
Thanks!

Problem with Time Dimension generating

Hello, everybody.
I have a problem with Time Dimension generating with the help of the Standard Wizard.
1. I choose Dimensions -> New -> Using Time Wizard
2. Set Name as "Time"
3. On the next screen I choose ROLAP: Relational Storage
4. On the next screen set Start year: 2003, Number of years: 3
5. On the next screen choose all levels of the Normal Hierarchy
On the 6-th step Wizard complete 60% of job and hang up doing nothing (buttons "Cancel" and "Help" is active).
chapter "Create REL_TIME Dimension Using the TIME Dimension Wizard", step 1-6 of tutorial =(

can anybody give me any advice about this problem? =(
thanks in advance.

Had this issue been solved please?
I have just come across the exact same problem and this post is the only one i managed to find which describes exactly what is happening to me.

Multiple Date Fields (Fact Table) - Linking with Time Dimension

I have a fact table that has multiple date columns.
I can make a time dimension, but it has to be joined to a particular date column. This becomes difficult because of the limit in having multiple date fields reference one time dimension. I can see possibly
creating a date table which contains all dates, link to fact as well as time dimension table. I am trying to better visualize the table layout on this one. Or are there possibily better ways of looking at this senerio
Any idea's

Figured this one out; going to use one time dimension - what looking too much into the details in regard to this scenerio

Time Dimension

I have created a Time dimension using the Dimension Wizard with two hierarchies:
Year - Quarter - Month - Date
Year - Week - Date
We have a data warehouse with two fact tables, FactSite and FactWell.
Each table contains a different date field and we hope to use the Time dimension as a role playing dimension for each.
So we wish to filter FactSite and FactWell data by
Year - Quarter - Month - Week - Date using
the operational date fields.
My queries are. Must we now:
1 - Populate (using wizard) the Time dimension with a suitable date range? (i.e. the start date and expected end date of our data set).
Then during our ETL process, we do a lookup in the Time dimension and set the surrogate key in the corresponding fact table.
2 - Populate the Time dimension during the
ETL process from our OLTP data source?
3 - What is the best practice for this type of scenario?

Hi Darren,
According to your description, you need a time table to create your time dimension, now you want to know which is better, creating the time table in the project or creating the table in the OLTP data source during ETL process, right?
Microsoft SQL Server Analysis Services provide a convenient way to create time table, you can use the Dimension Wizard in SQL Server Data Tools (SSDT) to create a time dimension when no time table is available in the source database. As per my understanding,
it better to generate the time table in data source view using wizard. Please refer to the link below to see the details.
http://msdn.microsoft.com/en-us/library/ms174832.aspx
Then you can create a Date hierarchy Year - Quarter - Month - Week - Date using this time table.

Frequency measurement using Labview 8 and Fieldpoint FP-CTR-502 - wind speed measure

All the information regarding this kind of application seems to be outdated, I did not find no solution or example to construct frequency measurement VIs using Labview 8
The examples at "NI Discussion Forums :
Most Active Hardware Boards :
FieldPoint Family :
Low-Frequency measurements using counter/timer" is very strange and so far the steps given seems to be usefull only do old Fieldpoint Explorer.
I was trying to find a way to learn how to make an anemometer send its signal to a FP-CTR-502 but I have no sucess.
I am realy very new on this Labview stuff, any help would be welcome.
