Question on Measure Calculation

Hello Experts,
I have a report with year, product, State columns and 2 measures payment 1 and payment 2, here i am trying to get national values for payment 1 and payment 2. So basically i want to compare state to national value of both the measures for each year for a product. currently i was trying out duplicating payment 1 measure and adding a filter in that measure by using sql expression option measure formula by year and i am getting an error. Please advise how can i accomplish my task.
Thanks

How to improve slow PowerPivot performance when adding/modifying measures, calculated columns or Relationships?

I have been using PowerPivot for a couple of months now and whilst it is extremely quick when pulling in data to populate Pivot Tables, it is extremely slow to make the following kind of changes to the Data Model:
- Add a Measure / Calculated Field
- Add a Calculated Column
- Rename a Calculated Field
- Re-name a Calculated Column
- Modify a relationship
- Change a tables properties
- Update a table
In the status bar of excel I get a very quick 'calculating', then it spends a lot of time 'reading data',
then it 'finalises' after which nothing is in the status bar but it still takes approx. 45 seconds before the program becomes responsive again. This waiting time does not change depending on the action, it is the same if I rename a
column as it is if I add a new measure.
My question is what affects performance of these actions and how do I improve it?
To give you an idea of where my data comes from, I have:
- 7 tables that feed into the Data Model directly from within the workbook which contains the data model itself. These are a combination of static tables and tables that connect to a MySQL database.
- 6 separate workbooks which contain static data that is updated manually periodically (copied and pasted from another source)
- 5 separate workbooks which contain dynamic tables that are linked to our MySQL database and update when opened.
Now I realise that this is probably where my issue is, however I have no idea how to fix it. You do not seem to be able to connect to a MySQL database directly within the PowerPivot window itself so there is no way to generate and update tables without
first creating them either in a worksheet or separate workbook (as far as I know). If I try to create all of the tables directly within the single workbook containing the Data Model I get performance and crashing issues hence why I separate tables into
individual workbooks.
Any advice on how to improve performance would be tremendously appreciated. I'm new and keen to learn, I'm aware this set-up is far from best practice.
Hardware wise I am using:
- Windows 8 64-bit
- Excel 2013 64-bit
- Intel Core i7 processor
- 6 GB Ram
Thanks,
James

Darren,
I think the point I was making is its in memory, geez... BTW what do all applications do when they run out of paged memory, if PowerPivot is using all available memory then wouldn't this force the other applications to use Virtual or essentially write
back and forth to the disks? I think Virtual memory white to disk ??, lol Also, there are parts if the architecture of Excel 2013 that when importing data into PowerPivot require memory and when working in SharePoint the PowerPivot data is cached to disk
unless recently refreshed... But this conversation isn't help the James who asked the question and as much as I would love to continue its become a little boring..
Hi James,
If you download one the ODBC MySQL Connectors
http://dev.mysql.com/downloads/connector/odbc/ and I believe yours is the first one for x64 systems and connect directly to the data you should be able to reduce the number of workbooks your opening and if you notice in the following graphic these
connection are automatically refreshed by default, the parts in red are the differences between PowerPivot 2010 and 2013
You should notice a lot of improvement especially when refreshing data please let us know how it goes...
After registering the ODBC Driver
Click Add. on the User-DSN sheet, choose the “MySQL ODBC 5.x driver”, fill in the credentials, choose a database (from the select menu) and a data source name and you’re done.
Back in Excel you go on the PowerPivot section of the ribbon and open the PowerPivot window (the green icon on the left side). In the ‘Home’ section of that window you will see a small gray cylindrical symbol (the international
symbol for “database”) which will suggest to you different data sources to choose from. Take the one where it says “ODBC”.
In the next dialog you click on create, choose the adapter, and then Ok. Back in the assistant you can check the connection and proceed.
Now you have the choice between importing the data from tables using the import assistant or Query depends on your skillset..

Ivan

Question about Measure folders Items (dimensions & measures)

Hi All,
I have tow question about measure folder
1-     How can I make measure folder contain both dimensions & measures?
     Like this image http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/bi/r10122/images/d1t10202.gif
2-     When I create measure folder and add some measures in it, when I query cube these measures still displayed out of folders how can I make all measures and dimensions displayed only on folders like the above image ?
Regards,
Gado

Hi Andy,
There should be no difference in functionality for these two kinds of folders. You can perform all the operations on these two kinds of folders without any difference, for example, delivery messages, create view settings/rules and etc.

Change the Label of a measured calculation in AWM-Model view

Hello,
Is there a way to change the name of a Short or Long Label of a measured calculation in the AWM (Analytic Workspace Manager) without dropping & re-creating it?
In the Model view it does allow you to make the changes to the label in the text field, and it does prompt you to apply changes. I Selected OK. However when I exit out of the AWM & log back in... I saw the old name back in :). It was like the changes were not "committed".
Thanks!

Hi
Thanks for your help, actually that option works for the total displayed as the latest row, I mean the label for the total row. However, for the total column, the name stays as the same as the measure label.
Can you further help me on the issue?
Thanks

Thanks for responding to my question. The annwer for your questions are: Measurment time : 300seconds, Sampling Frequency : 2 Hertz, and Window Type : Hanning. Hope you could hint me on this soon.

Thanks for responding to my question. The annwer for your questions are: Measurment time : 300seconds, Sampling Frequency : 2 Hertz, and Window Type : Hanning. Hope you could hint me on this soon.

ok, I see you posted parts of your VI in a different location. There is a sub-VI missing though ( Spline Interpolate.vi). But I re-constructed your data and can see the following things:
1 - Your signal has a significant DC-offset (approximatelly 1000) and this will result in a power value for DC of approximatelly 10E6 (though you wrote 10E8 in your first posting).
2 - If you ignore that DC, you can see on the time signal that there is another signal at very low frequency (order of magnitude amplitude = 10, power spectrum around bin 1 = 100) and you are not capturing an entire period of that signal, so either a measurement time of 300 seconds is not enough or this is a signal caused by a drift that you want to ignore.
But overall there is not much sign
al left once you remove your DC and eventually the very low frequency signal. But given your input signal, the power spectrum looks right. Remember also that the DC component will be replicated (with 6 dB reduction) on bin 1 when you apply a Hanning window. Try eventually without the Hanning window (but you'll still have to ignore your DC bin). Alternatively subtract the dc value from your time signal before computing your power spectrum.

How to get the measure total at row level for another measure calculation in DAX?

Hi There,
Using DAX, I am trying to get an expression for a calculated measure as follow:
So basically, I would like to get the AMeasure total highlighted in yellow in the A2Measure calculation:
Smeasure -(Ameasure total * WMeasure) where Ameasure total is the one highlighted.
I think my question would be how to get the total of a measure in order to used in the calculation of another measure.
Thanks and best regards,
Joss

Hi Joss83,
If you're trying to get the result for [AMeasure] at the total level (i.e. 5.09 in your example) you can do this by creating a version of this measures that is evaluated after ignoring the filters (indirectly or explicitly) placed on
the 'Customer' and 'Player' columns. You may also need to ignore the filters place on some other tables or columns that must be ignored in order for the correct total to be returned.
Without knowing much more about your data model, I can only take a vague guess as to what this calculation would look like in your scenario:
AMeasureTotal:=
CALCULATE(
[AMeasure],
ALL(Customer[Customer]),
ALL(Player[Player])
You can read more about the 'ALL' DAX function here:

Hope this helps,

Measure calculation based on hierarchy

Hi
I have flatten an account table to form a hierarchy of 5 levels, each level in this hierarchy will have a flag about account type,
So what I need now is a calculation which has to dynamically change according to this account flag object.
For instance, when account flag is u201CEu201D then the calculation should multiplied with minus. But I have 5 levels of hierarchy also with 5 account flags.
How can I consider these 5 account flags at a time to update the measure, is that possible in Web Intelligence?
I hope the following example for table structure can help to understand the problem.
Acct 1     flag1     acct2     flag2     acct3     flag3     acct4     flag4     acct5     flag5
AAA     R     AAf     E     AAD     E     AAD     E     VVv     L
BBB     R     DDG     E     EFR     R     AAD     L     ERR     R
CCC     E     FGF     R     DFS     E     SDD     R     FDF     E
I have created the five levels accts and flags as individual objects in universe and using it in the webi report as follows,
Report:
Account ( drillable to 5 level)                 Calculate.measure
AAA                                           545464
BBB                                          1654546
CCC                                           - 4674697
The above report should work in a way like when I drill down into account for the next level say. Acct2 , then it should check with corresponding flag (flag2 ) for its calculations (whether to add u2013 or + symbol)
Similarly on entering each level by drilling down, the calculation or formula should behave like above scenario, like it should check the flag and update the calculation
Is this possible ?
What kind calculation should I use ?
Thanks

Thanks for the your time and response.we don't have a year range column i might need to create one in rpd wondering if there is a way to do it in the analyses directly. I created a year range in the analyses by writing a case statement in one of the year columns. As per your suggestion here i might not be able to use a yer range in the measure denominator By year range.

Pivot measure calculation

Hi
I have to calculate new column(measure2) in pivot table
column1 measure1 measure2 (calculation%)
1 100 (100/100)*100
2 50 (100/50)*100
3 25 100/25 ..
4 10 100/10 ..
5 5 100/5 ..
the numerator is always first row's measure (ex:100 from above table)
Let me know how to achieve this,
Thanks

Can you use the logic that you specified in the data model (query) to generate the required data and then use it in the pivot table? That would be the easiest way to do it. Tweaking the code to include the conditional logic/calculated measures is not going to be straightforward..
Thanks,

Sorting measures (calculated members) in SSAS cube designer

Hi,
In SSAS 2012 cube designer, on the "Calculations" tab I am writing some simple calculated members and displaying it in a folder (Display Folder=)
FolderA
am So this FolderA has the members as below :
[<-A1], [-A1], [A],
[A1], [A2], [A3], [A4], [A5],
and [>A5]
While I am browsing the cube from Excel 2007, this FolderA is deployed correctly along with the above measures. All fine till here.
However, while I expand FolderA, Sorting is not done correctly. It is displaying like below :
<-A1, >A5, A, A1, -A1, A2, A3, A4, A5
But I want it to be sorted correctly so that it looks good as below :
<-A1, -A1, A, A1, A2, A3, A4, A5, >A5
How to do this at cube level ? Any property or any work around (using the latest SSAS 2012 version)
Thanks

Hi Yvanlathem,
I am not talking about sorting of folders/subfolders.
I want to short calculated members within the folder
As my first post itself says, For ex.,
in FolderA
this FolderA has the members as below :
[<-A1], [-A1], [A], [A1], [A2], [A3], [A4], [A5], and [>A5]
However, while I browse cube and expand FolderA ; Sorting is not done correctly. Currently it is displaying like below :
<-A1, >A5, A, A1, -A1, A2,
A3, A4, A5
But I want it to be sorted correctly as below (After
use of this solve order keyword it should sort as per below):
<-A1, -A1, A,
A1, A2, A3, A4, A5, >A5

National Measure Calculation

Hello Experts,
I have a report with year, product, State columns and 2 measures payment 1 and the formual is IFNULL(x,0)+IFNULL(y,0)+IFNULL(z,0) and payment 2 formula is IFNULL(x1,0)+IFNULL(y1,0)+IFNULL(z1,0) here i am trying to get national values for payment 1 and payment 2. So basically i want to compare state to national value of both the measures for each year for a product. currently i was trying out duplicating payment 1 measure and adding a filter in that measure by using sql expression option (IFNULL(x,0)+IFNULL(y,0)+IFNULL(z,0)) by year and i am getting an error. Please advise how can i accomplish my task.
Thanks,
RC

Thanks for looking into the question. I am trying to re frame the question again. I have Year, State, Product category(Auto,Baby & Children's product, Electronics,Home appliances, Misc) Revenue measure =IFNULL(tier1payment,0)+IFNULL(tier2payment,0)+IFNULL(tier3payment,0) here as you see the revenue measure is a custom measure which is a addition of tier1+tier2+tier3 payments. I am trying to have an additional measure for graphing purposes to compare state with national value for the product category for that year in order to do that i need to create a custom measure for national and how can i accomplish that. Please let me know if i am not clear.
Thanks,

Question about Measuring Point / Couter

Dear PM Guru,
While creating my Maintenance Plan with tcode -IP42 , there's counter automatically appear in the plan.
I under this counter is from measuring point.
I am confuse with the Counter in all this tcode IP41 , IP42 & IP01.
My question are :
Is this measuring point / counter master data or technical object ?
Where's the relationship for counter in Maintenance plan ?
Any impact the counter with the cycles used in the item line?
What 's the different between IP01 vs IP41 vs IP42?
Appreciate your input from any PM Guru.
TQ

Hi Venu,
Thank for your reply.
Understand that In Performance-based Maintenance Plan, SAP automatically links Counter to the Maintenance Plan.
After my personal investigation , fully understand that only performance based maintenance plan are using counter. Normal Maintenance Order will not use counter as Master data.
Example Performance Based Plans :
When the measuring point counter reaches 3000 -1st order should get generated
2nd one at 6000, 3 rd one at 9000 etc...
Or
1. Single Cycle with counter -- Ex . Maintenance every 3000 hrs
2. Strategy Cycle plans.. -- Ex. Maintenance every 3000 hrs and every 6000hrs
3. Multiple Counter Plans..-- Ex Maintenance every 2month or 1year..
Process Flow.
Create equipment with suitable measuring point (inc annual estimate) with Tcode IK01 create measuring point
Create initial counter reading measurement document
Create task list (optional for single-cycle plan)
Create counter based maintenance plan
Scheduling maintenance plan (IP10/IP30)
Create measurement documents periodically
Little Question to ask.
1) Is this the SAP standard flow ?
Please correct me if i am wrong.
Thank you.

Data not retrieved in WebI with Measures calculated in Universe on SAPBW

Hi,
Pls share if such error is faced anywhere else and if there is any solution to this.
Environment: SAP BI 7.01 and SAP BO XI 3.1 SP2 FP2.9
Universe has calculated measures.
Problem: No data is fetched by WebI when both direct measures (straight from BEx) and calculated measures are used.
However, data is correctly retrieved if either only the direct measures are used or calculated measures are used.
Thanks!

Good CKF parsed for you @ Universe.
If possible you can create Variable @WebI :
Var=[Grs Sales] + [Returns]
So that you can use it document (20 reports)
This way you can solves the issue as of now.
Gracias...!!

Using a string slicer value to filter measure calculations

Hi, I have 6 calculated fields that each provide a cumulative cost value for tasks in different categories. I would like to filter the total cumulative cost within one pivot chart to show only costs related to one project (out of a dozen or so).
I have a query which retrieves the project names, I have a relationship the costs and projects tables, however the measures will show me ALL project cumulative costs, and when I select each project name as a slicer value, only the X-Axis date range changes
to reflect the date range of the project. The cumulative costs remain the same, meaning the slicer value (project name) does not change the total cumulative costs in each category.
My formula for one of the calculated cumulative cost fields is below: (SumCapExAct is just
Sum([CAPEXACT]))
=IF (
    ISBLANK ( [SumCapExAct] ),
    BLANK (),
    CALCULATE (
        [SumCapExAct],
        FILTER (
             ALL(COSTS2) ,
            COSTS2[DATE]
                <= MAX ( COSTS2[DATE] )
Any Ideas on how I might have the selected Project Name filter the measures for each of my cumulative cost categories?
Thanks a million in advance!

Try changing ALL(COSTS2) to ALL(COSTS2[DATE])
Then the filters on the other attributes should work.
