Edit formula Aggregation rule?

What is the aggregation rule meant in formula tab?
What happen if I give aggregation rule in formula tab?
Will the aggregation rule in formula tab overwrite the predefined aggregation rule in UI/Repository?
If I want to change the aggregation rule only to the grand total where to specify?
Can I give two different aggregation rules each one for values and grand total respectively?
If I give aggregation rule “Default” in Formula tab what will happen?
If I give aggregation rule “None” in Formula tab what will happen?

Check the below link, the same can also get from Help link in Answers
All the aggregation functions are top of what you defined in the RPD, Aggregation rules in Answers will not override RPD aggregation rules, since RPD is base for Answers

Difference between aggregation rule and column formula in edit formula

Anybody please help what is the use of aggregation rule and column formula in edit column option.
What is the difference if I apply sum in aggregation rule with apply sum(column name) in column formula.
When do I need use which one.
Thanks in advance

When you build a column in the rpd, you have the option of determining if the column should be aggregated in some way or not. For dimension columns, you wouldn't put aggregation. For say, an accoun ledger balance column, you might put the aggregation SUM or AVERAGE. Whatever aggregation you put on this column will be the "default" aggregation of the column in Answers.
So in Answerrs, if you use the Account Ledger Balance column and you only have Region as the dimension, OBIEE will aggregate or SUM the ledger balances so you have a SUM for the region level. If you had district, than the ledger balance column will aggregate to the district level. This is a convenient way to build reports without having to specify what the aggregation should be.
However, OBIEE gives you the ability to override what the default aggregation is for a particular column. This is the purpose of the drop down in the bottom left of a column when you click the fx button.
Say the default aggregation of ledger balance is SUM in the rpd, but for the report you are building, you want the average, you can apply the AVERAGE function in the fx window and it will overridge the SUM aggregation rule that was in the rpd.
Got it?

EDIT AGGREGATION RULE IN ANSWER FOR A MEASURE

Hello Experts,
I have a measure in my fact table which is a "price" and I don't want to set up a default aggregation (sum, avg, max, min...etc) in my Business Model (Administrator). I want the user to be able to set an "Aggregation Rule" in Answers to that measure.
So, I go into Answer, select my measure from my model and then click on Edit formula and change the Aggregation Rule to "Avg" this seems to don't work.
I think I'm missing something, a setting or option.
I'll appreciate if you guys can help me with this...thanks.

Hey mma,
I'm referring to the "Edit Column Formula" option and then I click on "Column Formula". At the bottom of that tag there is a section that says "Aggregation Rule" with a drop down box that shows; Avg, Max, Min...etc. Thats where I make the change to "Avg" and it doesn't work.

OEE Report: KPI formulas and aggregation rules?

Hello,
is there documentation about the formulas and aggregation rules used in the OEE Report? Customers will only trust the KPIs in this report if they can verify them.
Formulas & Aggregation
How are the KPIs calculated?
How are the KPIs aggregated, if a work center or resource type is selected instead of a single resource?
Data & Variables
Which data is used? Where do the variables used in the formulas come from? E.g. which tables and columns or which SQL SELECT statements are used?
There is just very little information about the OEE Report in the online help or in the "SAP ME for Discrete Industries" document. And the MII "OEE Report Action", where obviously all the magic happens, is a black box.
Best Regards,
Martin

Hi Daniele,
Is Saichand correct in assuming that you have SUM setup in the BMM layer? If so, follow Saichand's recommendation.
If you are specifying the aggregation in the Answer Request itself, then try this.
Let's say this is your situation:
SELECT DIMENSION, MEASURE_1
FROM CRITERIA1
UNION ALL
SELECT DIMENSION, MEASURE_2
FROM CRITERIA2
UNION ALL
SELECT DIMENSION, MEASURE_3
FROM CRITERIA3
UNION ALL
SELECT DIMENSION, MEASURE_4
FROM CRITERIA4
Change it to this:
SELECT 'CRITERIA1' CRITERIA, DIMENSION, MEASURE_1 MEASURE
FROM CRITERIA1
UNION ALL
SELECT 'CRITERIA2' CRITERIA, DIMENSION, MEASURE_2 MEASURE
FROM CRITERIA2
UNION ALL
SELECT 'CRITERIA3' CRITERIA, DIMENSION, MEASURE_3 MEASURE
FROM CRITERIA3
UNION ALL
SELECT 'CRITERIA4' CRITERIA, DIMENSION, MEASURE_4 MEASURE
FROM CRITERIA4
Then in the combined criteria, add two new measures:
new_measnure1 = SUM(CASE WHEN CRITERIA in ('CRITIERA1','CRITIERA1') then MEASURE END
new_measnure2 = AVG(CASE WHEN CRITERIA in ('CRITIERA3','CRITIERA4') then MEASURE END
NOTE: The syntax for the new_measure* may need to reference the saw naming convention, ie. saw0 = CRITIERIA, saw1 = DIMENSION, saw2 = MEASURE.
That should work out for you.
Good luck and let me know if this helps.

Define custom made aggregation rules

Hi,
If I edit a column formula in Answers, many different aggregation rules (sum, average, count etc) are availabe. However, it doesn't seem possible to define my own aggregation rule, somelike "SUM(revenue)/9". Isn't this possible?
TIA!
Edited by: Erik on 28-Mar-2011 14:44

In answers we can give sum(revenue)/9 but it shows the same result for all the rows.If u r having any other column in the criteria ie dimension the give like this
Sum(revenue by dimension)/9

Answers and Aggregation rules not working

Hi everyone!
I have this problem: in my repository I set "none" in the aggregation rule for a field... but if I try to make aggregations in the answer (with the dropdown list in "Edit formula") they don't work at all, I always get the same result even if I change from default to sum to average to count...
Is it a bug? Does anyone have any workaround?
P.S.: if I use the function sum(...) in the formula it works... but I'd like to use the aggregation rule's combo box!
Thanks so and.. have an happy new year!
DrPlexi

The aggreagation in answers is for the summary of the results ( that is when you use ∑)

How to define an aggregation rule for a dimension based on bridge table?

Hello,
I need a solution for aggregating data correctly when using a dimension based on a set of dimensione tables containing a bridge table. Please find below a description of my business case and the OBIEE model which I’ve created thus far.
Business Case
The company involved wants to report on the number of support cases, the different types of actions that were taken and the people involved in those actions. One support case will undergo a number of actions (called ‘handelingen’) until it is closed. For each action at least one person is involved performing a specific role, but there can also be multiple persons involved with 1 action, each performing a different role for that action. This is the N : N part of the model.
The problem that I face is visible in the two pictures below:
http://i84.photobucket.com/albums/k24/The_Dutchman_2006/OBIEE/sample.png
As long as I don’t include anything from the Dimension Meelezer in my report, I get the correct number of handelingen (7). When I include the person (called ‘Meelezer’), the measuere per action is multiplied by the number of persons/roles involved with that action.
When I changed the Aggregation rule in the report column #Handelingen to ‘Server Complex Aggregate’ I do get the correct endtotal:
http://i84.photobucket.com/albums/k24/The_Dutchman_2006/OBIEE/sample2.png
I believe it should be possible to define in the repository a different aggregation rule for individual dimensions, but I’ve not been able to achieve this.
Explained below is what I have created in my Physical and Business Model & Mapping layers:
The Physical Model is built like this:
(This is just a small part of a much larger physical model, but I’ve only included the most relevant tables)
http://i84.photobucket.com/albums/k24/The_Dutchman_2006/OBIEE/PhysicalDiagram-1.png
The Fact table (ALS Feit Zaakverloop) contains FK’s for the action (FK_HANDELING, joined to ALS Dim Handeling), the date the action took place (FK_DATUM_ZAAKVERLOOP, joined to ALS Dim Datum Zaakverloop) and the uniqe group of people involved (FK_MEELEZERS, joined to ALS Groep Meelezers) and a measure column (SUM_HANDELINGEN) populated with the value ‘1’ for each row.
The Bridge table (ALS Brug Meelezer/Reden Meelezen) contains three FK’s: FK_GR_MEELEZERS (joined to ALS Groep Meelezers), FK_MEELEZER (joined to ALS Dim Functionaris) and FK_REDEN_MEELEZEN (joined to ALS Dim Reden Meelezen).
The Business Model
In the business model, the four physical tables for the N:N relation have been combined into one logical dimension table.
http://i84.photobucket.com/albums/k24/The_Dutchman_2006/OBIEE/BusinessModel-1.png
DIM Meelezer contains one LTS in which the four physical tables have been combined:
http://i84.photobucket.com/albums/k24/The_Dutchman_2006/OBIEE/LTS1.png
And all the required locical columns have been created:
http://i84.photobucket.com/albums/k24/The_Dutchman_2006/OBIEE/LTS2.png
DIM Meelezer has also been identified as a bridge table and a Business Key has been defined on a combination of the FK’s in the bridge table and business codes of the two dimension tables.
http://i84.photobucket.com/albums/k24/The_Dutchman_2006/OBIEE/BMDIM.png
Next a hierachy was created for Dim Meelezer:
http://i84.photobucket.com/albums/k24/The_Dutchman_2006/OBIEE/Hier.png
In Feit Zaakverloop, a measurement called ‘# Handelingen’ was created using SUM_HANDELINGEN, with an aggregation rule of SUM.
In the LTS of both the DIM Meelezer and Feit Zaakverloop, the Logical Content Levels have both been set to: LVL Detail – Meelezer.
Please provide suggestions that will NOT require changes to the physical datamodel as they would require too much time to achieve (or at leats would not be ready before my deadline.
Thanks!

Am I in 'uncharted territory' with this issue?

Direct Database Request Aggregation Rule

How can I do aggregations on a report created with a direct database request? While I can set the default aggregation rule in the fx formula, the aggregate E sign does not appear in the table view. How do I actually get to do a summation of the column?
Thanks,
Dinesh.

I guess I celebrated too soon. Now I lost the ability to display Columns & Table headings as separate rows. How can I accomplish the grouping of different columns under headings the way I accomplished with 'Columns & Table headings' as separate rows?
Thanks,
Dinesh.

The reasoning behind aggregation rules at report level

Hello guys
I notice that in the answer criteria, we can define column formula of each columns in the request, but we can also set aggregation rules for the numeric columns..
I'd like to have a deeper understanding on how these settings work..
The Avg, Max, Min, Count are pretty clear and self-explanatory to me.
My main question is the difference between 'default', 'Server determined', 'complex server aggregate', and 'Sum'.
In a lot of the measure columns when the aggregate rule is 'default', when I do subtotaling in report views, I would actually get the right total amount by dimension columns, however there are also places in the report where the sub total is off, so I have to go and set the aggregate rule of that measure to 'Sum' then the total becomes correct 100%. When I try 'server determined', 'complex server aggregate', some measures change and some don't, but this is not in a pattern of change that I can understand the concept behind. The OBIEE documents said very little about this part
So is there more detailed information out there that explains more about what these options are doing?
Thanks in advance

Hi Shruthi,
To be clear you have one table 'DIM_LF_B' and its separated out as FACT and DIM in BMM layer with respective formulas ? If yes check this http://www.varanasisaichand.com/2012/04/fact-and-dimension-from-single-source.html
let me know if it is different

Default Aggregation Rule

Can someone explain me as to how BI interprets the default aggregation rule.
Say when we say the defualt aggregation rule on the sales fact table column revenue is SUM. what does it actually imply.
Similarly when we use the Aggregation Content tab in the Logical table source and set aggregation content group by what does it actually mean.
Thanks,
Chan

If you didnt set content tab that would be default aggregation, means based on the columns pull in the criteria SUM changes like drill down or roll up.
'Group by' clause keep on changes as per the column in the criteria.
When you set any level for a metric then it alway aggregated to that level, values will not change as per column selection.
Pls mark if helps

Aggregation rules for calculations

Hi
I have a calculation (logical column) Z as X*Y and I want Z to be an average at different levels in hierachy. How do I do it in OBIEE?

Hi Siddharth,
Specifying Aggregation rule for a column in Admin Tool and applying Formula for a column in Answers work differently.
We usually specify Aggregation rule in Admin tool to implement the calculation measures. So, it will be used along with the logical levels.
Where as specifying Formula for a column in Answers works for that particular Request only..
Comes to its Significance...
Take the general example... Sales by Country, Region, District and City
To calculate the total sales Country, Region, District and City wise we specify aggregation rule as SUM for the Amount column..
In order to calculate the logical level wise details we use Aggregations..i.e., Measures..
For last question, is your saying the use of 'Use Existing Logical columns as the Source'..
In this case, I think it is not possible to specify the Aggregation rule in Admin tool.

How to set Grand Total of a Measure when its aggregation rule is Max in Logical Layer

Hi
I have a Measure Column (Budget) and in Logical layer the aggregation rule is set as (Max) which looks like Max(Budget). But now it is included in the report and when my client is trying to see its grand total, it is giving the Max Budget figure of the report rather than giving the total sum(grand total).
Kindly share some ideas in achieving the grand total without disturbing the actual aggregation of the measure.

Thank You for your reply.
In my case i don't have a problem with aggregation for Budget Measure(max(Fact_XXKC_SHIP_TO_BUDGET_CAT_F.SALESREP_BUDGET_YTD)). This is the aggregation rule applied on the Salesrep Budget YTD.
Now i created a report with columns
Salesrepresntative(Dimension),, Sales Invoices(Measure1),, SALESREP_BUDGET_YTD(Measure 2).
In the above report the values are perfect, but when we used Grand total option at ROW level in table view, the grand total of Measure1 is cumulative of all the rows, but the Grand total of SALESREP_BUDGET_YTD (measure2) is the max of all the columns.
What i require is the Grand total of SALESREP_BUDGET_YTD (measure 2) should be cumulative of all the columns.
I have shared my SQL query, kindly verify it and share any idea.

Aggregation rule ignored for Logical sources

Hi,
We are using materialized views as logical sources for our logical tables. These logical sources contain aggregated data at higher level for dimensions. However, we have a logical source at the most detailed level for the dimensions.
Problem: We OBIEE hits the correct logical source based on dimensions selected in answers, it does not apply the default aggregation rule.
For instance, if a measure has aggregation as AVG, then when the logical sources corresponding to aggregated tables are queried, OBIEE does not apply AVG function. However, it does apply the aggregation rule when it uses the logical source at the most detailed level.
I have specified the aggregation content properly for every dimension.
Any pointers to debug the issue will be helpful.
Thanks,

Click on LTS of Table - Column Mapping - Select the logical column - click on expression - Put your logic here. You will get Aggregation rule is enalbed for the column.
Why ? -- Reason could be nested aggregation is not allowed. Aggregation on the normal column applied during query generation at run time. If you use that Agg.Measure to derive another Agg.measure server could not recognize it during runtime.
