Complex DAX Calculation
Hi,
I have an excel calculation that I have tried to convert i into a powerpivot measure. The excel calcualtion is as below:
(IFERROR(IF(1-ABS((TOTDEMANDQTY-REVISEDFRC)/TOTDEMANDQTY)<0,0,(1-ABS((TOTDEMANDQTY-REVISEDFRC)/TOTDEMANDQTY))),"0.00")
I was given some great advice to change it to the below as a measure and it almost works but not quite:
Some Measure:=if(DIVIDE(ABS(FAReportInput[Demand]-FAReportInput[Revised Forecast]),FAReportInput[Demand],0)<1,1-DIVIDE(ABS(FAReportInput[Demand]-FAReportInput[Revised Forecast]),FAReportInput[Demand],0),0)
The issue is where I have a revised forecast of an amount but a demand of zero I am returning a value of 1 when in fact it should return a value of zero as per the iferror in the excel formula- can anyone help?
Thanks

Complex SQL calculated/Group Query
I am trying to write a complex aggregate query(s) to compile a standings table for a soccer league.
There are four related tables:
Matches
Goals
Players
teams
I have yet to finalize the database structure so I can add fields if necessary.
In the goals table I track the match that the goal was scored in and which player
scored it.
I am trying to create a query that will give me a standings table.
The fields I need to calculate are:
team name
Wins
Loses
Draws
For instance: There was a match on 4/21/2012. The players on HomeTeam(A) scored a combined 6 goals. The players on AwayTeam(B) scored 1 goal (All stored in the Goals table). Therefore, Hometeam won by a score of 6-1. I need
a query that spits out:
Team Wins Losses Draws
Points
HomeTeam(A) 1 0 0
3
AwayTeam(B) 0 1 0 3
Wins are worth 3 Losses 0 and Draws 1 point each team.
I am a long time SQL admin, but I think the complexity of calculating this is a little beyong me. I need some help to get where I need to be.Okay, I haven't yet been able to figure out the draws because of the trouble of linking back to both teams, but here's what I have so far.
First, here is the test data:
Declare @tvMatches Table (
MatchID int IDENTITY(1,1)
,MatchDate datetime
,HomeTeamID int
,AwayTeamID int
Declare @tvGoals Table (
GoalID int IDENTITY(1,1)
,MatchID int
,PlayerID int
,TeamID int
Declare @tvPlayers Table (
PlayerID int IDENTITY(1,1)
,TeamID int
,PlayerName varchar(30)
Declare @tvTeams Table (
TeamID int IDENTITY(1,1)
,TeamName varchar(20)
Insert @tvTeams
Select 'Winners'
Union All
Select 'Losers'
Union All
Select 'Friars'
Union All
Select 'Planes'
Insert @tvPlayers
Select 1, 'Bill'
Union All
Select 1, 'Jim'
Union All
Select 1, 'Ken'
Union All
Select 2, 'James'
Union All
Select 2, 'Smithy'
Union All
Select 2, 'Flip'
Union All
Select 3, 'Dave'
Union All
Select 3, 'Alan'
Union All
Select 3, 'Ethan'
Union All
Select 4, 'Naomi'
Union All
Select 4, 'Erland'
Union All
Select 4, 'Alejandro'
Insert @tvMatches
Select '20120101', 1, 2
Union All
Select '20120201', 3, 4
Union All
Select '20120301', 4, 1
--Winners beat Losers 3-2
--Planes beat Friars 4-2
--Winners beat Planes 2-1
Insert @tvGoals --Match, Player, Team
Select 1, 1, 1
Union All
Select 1, 3, 1
Union All
Select 1, 5, 2
Union All
Select 1, 6, 2
Union All
Select 1, 2, 1
Union All
Select 2, 7, 3
Union All
Select 2, 8, 3
Union All
Select 2, 10, 4
Union All
Select 2, 11, 4
Union All
Select 2, 12, 4
Union All
Select 2, 11, 4
Union All
Select 3, 1, 1
Union All
Select 3, 3, 1
Union All
Select 3, 11, 4
Using this test data, you want to compile the actual match outcomes. This can be problematic to do on the fly every time though, if you have a lot of matches or teams to calculate for. But, with a simple cte, we have:
;with cteMatches as
Select m.MatchID
,m.MatchDate
,m.HomeTeamID
,ht.TeamName HomeTeamName
,m.AwayTeamID
,at.TeamName AwayTeamName
,( Select Count(1)
From @tvGoals g
Where g.MatchID = m.MatchID
And g.TeamID = m.HomeTeamID
) HomeScore
,( Select Count(1)
From @tvGoals g
Where g.MatchID = m.MatchID
And g.TeamID = m.AwayTeamID
) AwayScore
From @tvMatches m
join @tvTeams ht
on m.HomeTeamID = ht.TeamID
join @tvTeams at
on m.AwayTeamID = at.TeamID
) --select * from cteMatches
This returns the MatchID, MatchDate, team information and the score. Basically, you have the match, team and player data tied to the goals table, so you just do a count (using correlated subqueries) to get the score of each team. Next step is
to calculate the winner and loser (and eventually whether there even was a winner) by comparing the scores:
,cteWinners as
Select cm.MatchID
,cm.HomeTeamID
,cm.HomeTeamName
,cm.AwayTeamID
,cm.AwayTeamName
,Case
When cm.HomeScore > cm.AwayScore Then cm.HomeTeamID
When cm.HomeScore < cm.AwayScore Then cm.AwayTeamID
Else 0
End WinningTeamID
,Case
When cm.HomeScore > cm.AwayScore Then cm.AwayTeamID
When cm.HomeScore < cm.AwayScore Then cm.HomeTeamID
Else 0
End LosingTeamID
From cteMatches cm
) --select * from ctewinners
This returns MatchID, team information and the ID's for winning and losing teams. For now it returns 0 if it's a draw. Once we know the outcomes of all the matches, we calculate the actual win/loss for each team:
,cteRecords as
Select t.TeamName
,Count( Case
When cw.WinningTeamID = t.TeamID Then 1
End
) Wins
,Count( Case
When cw.LosingTeamID = t.TeamID Then 1
End
) Losses
From @tvTeams t
join cteWinners cw
on t.TeamID = cw.HomeTeamID
or t.TeamID = cw.AwayTeamID
Group By t.TeamName
) --select * from cteRecords
That last cte returns just team name, and then the number of wins and losses for each team. This is where I got stuck with the draws, because I'm not quite sure yet how to properly assign a draw to both teams involved.
Now, finally you put it all together with some simple match to determine the points, and there you are:
Select TeamName
,Wins
,Losses
,(Wins * 3) Points
From cteRecords -
If then Else using DAX Calculation
Hi all, new to DAX. I am trying to replicate a Oracle SQL column using DAX functions in SSAS Tabular.
My Oracle column is defined like below:
If STATE_CODE Not in('A','B','C','D')
And Not (substr(PK_ID,4,2) = 'XY' And DIV_CODE in('YU','SD')) Then
CNT = 1;
Else
CNT = 0;
Any ideas how to start? Should i use DAX Switch function ?
Thanks,
TAGWe have IF and Switch Function Available in DAX .
You can use any of one.
IF(logical_test>,<value_if_true>, value_if_false)
For Switch you can use below;
SWITCH(TRUE(),
booleanexpression1, result1,
booleanexpression2, result2,
else
Just create calculated column in Cube and add this logical IF/Switch function there.
Or If you want to calculate this at query level using DAX then you can follow below Query.
Evaluate
ADDCOLUMNS
TableName,
, "calculated column"
,IF( Logical,Truecondition,False Condition)

DAX Calculation shows incorrect results when driven from Time Slicer
Hi,
We have defined a DAX quarter on quarter calculation
PREV Q % 13F:=divide([PREV Q ABS 13F],[Prior Quarter 13F])
Prior Quarter 13F:=CALCULATE(sum([TotalValue]), DATEADD(Time[Date], -1, QUARTER))
PREV Q ABS 13f:=CALCULATE(sum([TotalValue]))-[Prior Quarter 13F]
which works fine in Pivottables in Excel but when time selection is driven by a time slicer the calculation doesn't work anymore:
Is this a but or expected behaviour? Are there other ways to use a control that affects multiple other pivot tables like the time slicer?
Thanks for your help!
MartinOK, there are some really interesting points here - i think the screenshot below best explains it:
Time Slicers use MDX subselects to propagate the selection to the pivot table:
SELECT .... FROM (SELECT Filter([Fact13FSample].[ReportDate].Levels(1).AllMembers, ([Fact13FSample].[ReportDate].CurrentMember.MemberValue>=CDate("2013-04-01") AND [Fact13FSample].[ReportDate].CurrentMember.MemberValue<CDate("2013-07-01")))
ON COLUMNS FROM ...
this works just fine for normal measures but seems to cause issues with time-intelligence function
it actually causes an issue with all calculations that use CALCULATE and thereby shift the context out of the subselect
it seems that you cannot get out of this context using DAX- at least i could not find a solution yet
not even this works:
All Quarter 13F:=CALCULATE([SumTV], ALL('Time'))
the result is always limited to the subselect :/
funny thing is that this only seems to happen with this specific subselects so i guess it is further related to MDX FILTER() or .MemberValue or CDATE()
the only option i could currently think of is to use regular slicers

Trailing 4 quarters DAX calculation on an aggregated level
Hi,
I am having difficulties with the calculation of the last 4 quarters in DAX. I am using a standard fact table and a separate time table (Time). The calculation works fine on the quarterly level but I can't find a way to display the correct results on a total
year level.
My calculation is as follows:
Dividends TTM:=CALCULATE([Dividend],
DATESBETWEEN(Time[Date],
DATEADD(FIRSTDATE(time[date]),-3, QUARTER),
LASTDATE(time[date])))
Thanks a lot for your help!So I think it's actually returning 4 Quarters and 1 day which you could fix with something like the following:
Dividends TTM:=CALCULATE([Dividend],
DATESBETWEEN(Time[Date],
DATEADD(DATEADD(LASTDATE(time[date]),-4, QUARTER),1,DAY)
LASTDATE(time[date])))

Need help on complex math calculation in labview
I need some help by being pointed in the right direction. I have a piece of old lab equipment that I will be connecting to labview. In order to send commands to the hardware, I have to calculate a checksum. The checksum algorythm requires me to take alphanumeric characters, convert them to binary, perform binary addition, perform an Xor, mask certain digits, and convert the resultant binary string back to an ascii character. Does labview have the capabilities to do this on it's own, or should I look at connecting to something like an external dll?
I have Visual Studio 2008 and some previous VB experience, so I think I could write a program that would do the calculation, but don't really know exactly what type of project (dll, etc.) is best. Are there any specific settings for the dll so that labview can use it. I see an example for C++ for Visual Studio 2005, but that is as close as I can get. I only know VB, not C# or C++
Can someone please point me in the right direction?

Spreadsheet structure - complex cost calculation
I am trying to set up a semi-automatic spreadsheet that will help me prepare quotes for building work.
I would appreciate any advice on the best set up that would for this and possible functions I would need to use to make it work. I tried finding a suitable solution or a template but to no avail.
I'll try to explain the requirements as clearly as I can, but please let me know if there is any further explanation you may require.
1. I have many tables that I set up to calculate costs and prices of particular types of work, i.e. building a brick wall or laying foundations
1.1 Each table has the same columns such as'type of resource', 'quantity', 'price per unit', 'cost', 'profit', 'price'
1.2 Each table has a different number of rows, depending on number of resources required for the particular type of work, some of the tables have multiple header rows to allow for data entry cells, such as 'length' or 'height'
1.3 I keep the tables in a separate file and just copy the ones I need for particular quote, one type of table may be used several times in a quote, depending on type of job quoted, i.e. I may have more than one wall to price
2. The main sheet of the quote has a table that lists all the items of work I need to price
2.1 The columns are: 'item id' (unique number), 'item description' and 'tender price'
2.2 'tender price' is manually linked to 'total price' in the relevant calculation table (I gathered here that perhaps using INDIRECT function will allow the link to be automatic, correct?)
2.3 Right now I use 'item id' as the name of the relevant table to be able to recognise which item it calculates
3.0 I need a summary sheet with few tables that will give me various information. The information required is:
- materials list and quantities collected from all the calculation tables
- labour list as above
- labour and materials per build stage (I need to add stages to the tables first)
I'm not sure this can work with me using separate tables for each item calculation. I think that if I put all the calculations into one, big table I may be able to pull info out by using categories, however I would like to avoid this as I would end up with very large, messy tables on larger quotes.
I have used excel and a combination of outline and pivot tables in the past, but it was by no means a perfect solution.
I hope my explanation is clear and I do appreciate your help.
Regards
BartBart,
I think I have what you were looking for. I only addressed what I thought was your concern.
1. I added a table to your "general calculators" sheet, and called it "Data"
2. I utilized the VLOOKUP and the INDIRECT functions to make your Totals more dynamic.
3. The formula is going to look to the table referenced in the "A" column of the line. (A3 = 1.1)
4. The formula will then look at the column heading and find the number in the "Data" table I added.
5. The lookup will then go over this many columns to find the value of the "Total" line.
You should be able to copy this formula to all the cells you are looking for the total of. As an example, copy cell C3 to C12. Then range fill to F22. Delete the formulas in C16 and D16 as they will error, because they are not necessary. Repeat the procedure for Job 3, etc.
If you change the Job (Table) reference in column "A" this will automatically look to the correct table. If you need to add a column some day, Add the column to all the appropriate tables, then add the name and column number to "Data." It should then recalculate correctly.
I have posted the spreadsheet here:
https://www.iwork.com/r/?d=samplequoteRevised.numbers&a=p108776228
If it you cant get to it, let me know....and we can try something else...since I dont have a mobileme account.
Let me know if you have ANY questions.

Dax Calculating Same time previous period with nonstandard periods
I need help dealing with prior period calculations where the periods are not standard.
In our business we define these time periods based on 8 to 10 week periods that really have no correlation to standard weeks, months or quarters. Additionally there may be some time between these periods that are not defined. For example:
Period 1 (p1) = June 18 - Sept 2
Period 2 (p2) = Sept 17 - Dec 9
The length of the periods are variable and when one ends another does not necessarily begin.
I need to figure out how to compare the sum of a metric in Period 2 with the sum of a metric in Period 1.
I have a standard Date dimension. And I have a period deminsion with the period labels (p1, p2 etc.) the start date, the end date of the periods, and a column called previousPeriod that has the label of the prior period.
Each Fact has a Period ID so that I can use period as a dimension.One of my measures is Sum(sales).
I want it so that if I am viewing the Tabular cube by period, I can have the sum of sales for that period, and the prior one. I hope it is clear what I am trying to do.You should add to your Date table a column that contains an incremental number for each period, then write something like:
CALCULATE
[Sales],
ALL
( 'Date' ),
FILTER
ALL
( 'Date'[IncrementalPeriod] ),
'Date'[IncrementalPeriod]
=
EARLIER ( 'Date'[IncrementalPeriod]
) - 1
I suggest you this pattern that will be published on March 31 - it contains many more examples, including how to write the make this formula working also with a partial arbitrary selection of days in the selected period:

Complexe percentage calculation
hi,
I would like to compute percentage based on this table between ticket and CA based on BUV and ID parameters:
ID
BUV
Ticket
CA
103
BUV31
2 274 €
32 662 €
103
BUV2
1 979 €

104
BUV2
2 311 €
40 900 €
104
BUV14
2 283 €
40 900 €
with a power pivot table we have that:
Étiquettes de lignes
CA
Ticket

97985,37
6042,14
6,17%
BUV2

BUV31
32661,79
2274,44
6,96%
BUV35
32661,79
1788,46
5,48%

2491,94
6,09%
Total général
110342,265
13127,96
11,90%
where foor CA I created a DAX formulas in calculate Field:
sum([CATotal])/DISTINCTCOUNT([OPFSessID])
and for Ticket I created in calculate Field again:
[SommeTicketTotal]
And the result of the percentage field is still a Calculate Field which is the result of CA/Ticket comuted previously.
It works perfectly if I want to display only one ID. But if two ID are displayed, the computation is the sum of percentage which is of course wrong.
For instance if I think about BUV31, i should have 6.47% instead of 12.96%. How can I add buv parameter into the formula to get the right result?Hi,
Yes it is correct. I created a table with only BUV elements and theire percentage.
Here is the table:
Étiquettes de lignes
pct
BUV14
5,58%
BUV2
11,66%
BUV31
12,96%
BUV35
5,48%
Total général
11,90%
As you can see BUV31 has 12.96% but it is wrong it should appear ticket (2274.44+2491.94) / CA (32661.79+40889.72) = 6.48%. So, 0.1296*32661.79=4233. It use 4233 as ticket values. No idea about where it come from.
I think I should add into the CA calculate field something like "group by" BUV. -
Hello everyone!
I am working on this code to compute complex numbers (a+-bi) and I am a little stuck - I get an error message:
<<<invalid method declaration; return type required>>>public ComplexN( double re, double im)>>>>
Please, can anyone help me.
public class Complex {
private double real = 0.0;
private double imaginary = 0.0;
public Complex() { this( 0, 0 );}
double r = real;
double i = imaginary;
public ComplexN( double re, double im) { this(re,im);}
public Complex add( Complex a, Complex b ) { return new Complex(a.r + b.r, a.i + b.i);}
public Complex subtract( Complex a, Complex b ) { return new Complex(a.r - b.r, a.i - b.i);}
public String toString() {return String.format( "(%.1f, %.1f)", real, imaginary );}
Object[] add(Complex b) {return null;}
Object[] subtract(Complex b) {return null;}
==================================================
public class ComplexTest
public static void main( String args[] )
Complex a = new Complex( 9.5, 7.7 );
Complex b = new Complex( 1.2, 3.1 );
System.out.printf( "a = %s\n", a );
System.out.printf( "b = %s\n", b );
System.out.printf( "a + b = %s\n", a.add( b ) );
System.out.printf( "a - b = %s\n", a.subtract( b ) );
}If you take the N off the name, you get this:
public Complex( double re, double im) {
this(re,im);
}OK, now walk through an instantiation like this:
Complex c = new Complex(1.0, 1.0);You call that constructor. And that constructor then delegates to the constructor that takes two double arguments. That is, it delegates to itself.
So it would just go on delegating to itself for eternity. This is bad. -

I would like to know if it is possible to create a calculation that will behave differently depending on the dimensions dragged on a grid, basically, I have two date dimensions and depending on which dimension is put on the rows or cols (or both!?) for the

thx much for any pointers,

Thank you for your answer.
Q. As for processing of your WT X000, what are it's Valuation Bases in V_512W_B ?
- it is valuated in current wagetype and Valuation basis 092 and rate is 150%.
Q. Have you checked through pe04 what is operation VAKEYALZNR ? Isn't it related to Alternative Payment ?
yes, it is alternative payment.
P.S. : 12.07 x 1.5 = 18.105, which will give 18.11 once it is rounded up.
A: we never used any round up function,
Though we not used the roundup function why it is rounded up. How and where can we remove this roundup.
Thank you for your help.

Complex Mathmatical Calculation
My project for the summer is to create a desktop calculator that accepts any altitude between Sea Level and 10,000 feet and any temperature between -15 and 45 degrees Celsius and then automatically displays an aircrafts maximum allowable takeoff weight. Creating the Panel, text boxes, labels etc are no problem with my basic Java programming knowledge but I have no idea where to start with the actual calculations. I would imagine some sort of algorithm would be used but know basically nothing about them. Help getting pointed in the right direction would be greatly appreciated.
Here's a link to an Aircraft Weight, Altitude and Temperature Chart (WAT Chart) so you can see what I'm talking about. The personal web page is about 110KB because of the chart so it might take about 10-20 seconds to load is you're using a dialup connection. Any help would be greatly appreciated.
http://mywebpage.netscape.com/MichaelEKauffman/
Thanks in advance!You are right - the posted chart is only applicable to a Hawker Siddeley 125-700A when using 0 Degrees flaps and the automatic performance reserve system (APR). I have similar charts that use 15 degrees flaps and even those that include the use of thrust reversers and with and without the APR. From the posts so far it appears I have my work cut out for me this summer and will be brushing up on my Calculus. The feedback thus far has been greatly appreciated and thanks in advance for any others who have additional feedback or ideas.
By the way, the posted Weight, Altitude and Temperature Chart (WAT Chart) is the least complicated of the Summer Project. There are also Takeoff and Accelerated Stop Distance charts, First and Second Segment Climb Gradient Charts among others for the same aircraft. My thoughts were if I could figure out how to do the WAT Chart then figuring out other more complicated charts would become a little more obvious. More charts could be posted to my personal web space if somebody indicated an interest. Thanks again everybody for the help!

Hi All
I have tough task ahead and i need your help.I have to create a rebate which is used during sales from consigment .It is supposed to work in such a way it takes the amount in the current sales order and minuses it from the amount of material still at consigment(1000 at consigment - 200 at sales order) .The differenece (800) is the base for calculation.We take 800* current price * 2%.The outcome is subtracted from the sales amout (200).The same thing should happen with normal sales but the rebate should not take into account the amount previously sold on the reference document and the discount is on the credit memo request .Does anyone have any good tips how to get started with this ?please:)Hi Grinch,
