RankX within a subset of a group - filter

I am relatively new to PBI and I am trying to add a Rank measure that will Rank a product (within a product group) highest price to lowest:
Product Number Net Price Desired Result
Cat $7.00 1
Cat $6.00 2
Cat $5.00 3
Cat $4.00 4
Dog $3.00 1
Dog $1.00 2
The measure I've added comes up as an error: ​Rank Price by Product: RANKX(ALL('Product Table'),[Net Price]).
Any help would be greatly appreciated!

You can try this
_maxOfRow =
MAX ( 'Product Table'[Net Price] )
_rank =
VAR _0 =
CALCULATE ( MAX ( 'Product Table'[Product Number] ) )
VAR _1 =
RANKX (
FILTER ( ALLSELECTED ( 'Product Table' ), 'Product Table'[Product Number] = _0 ),
[_maxOfRow],
,
DESC
)
RETURN
_1

Power Bi: how to parameterize Top N visual level filter [duplicate]

This question already has answers here:
Power Bi: Top N visual level filter as Measure
(2 answers)
Closed 6 months ago.
Since PowerBI don't support Top N filter on page level,
I want to use N as a parameter to change it at once per multiple visuals.
Is it possible?
P.S.In this video (9:15) solution for more complex case is provided.
In the end of this article sample file available
Using the sample dataset, insert a new parameter.
Add a measure as follows:
Measure =
IF(
SELECTEDVALUE('Product'[Product Name]) IN
SELECTCOLUMNS(
TOPN(
[Parameter Value],
ADDCOLUMNS( ALLSELECTED( 'Product'),"#Sales", [Sales Amount] ),
[#Sales]
),
"x",
'Product'[Product Name]),
1)
Every visual you want affected by the TopN should have this filter.
That's it.
From usability perspective it's preferable to return Sales Rank in measure.
Solution below is a copy/paste from SQLBI experts solution with minimal code changes ( ALLSELECTED ( 'Product'[Product Name] ) replaced by ALLSELECTED ( 'Product' ) ):
rnkSales =
IF (
ISINSCOPE ( 'Product'[Product Name] ),
VAR ProductsToRank = [TopN Value]
VAR SalesAmount = [Sales Amount]
RETURN
IF (
SalesAmount > 0,
VAR VisibleProducts =
FILTER( -- filters out data with no sales
CALCULATETABLE (
VALUES ( 'Product' ),
ALLSELECTED ( 'Product') -- Use this if VisualFilterTopN equivalent required
//ALLSELECTED ( 'Product'[Product Name] ) -- Original code - returns TopN per dimension
),
NOT ISBLANK( [Sales Amount] ) -- looks more universal then [Sales Amount]>0 (if calculation for Margin required, it could be negative)
)
VAR Ranking =
RANKX (
VisibleProducts,
[Sales Amount],
SalesAmount
)
RETURN
IF (
Ranking > 0 && Ranking <= ProductsToRank,
Ranking
)
)
)

DAX Index and Match function?

I'm trying to use function LOOKUPVALUE, but I have more than one ID and return error "A table of multiple values was supplied where a single value was expected"
For example:
I need to fill all lines in "Measure_id"
Group_ID
ID
Desc
Measure_ID
112233
0
close
12345
112233
12345
open
12345
112233
0
close
12345
223344
0
close
23456
223344

23456
223344
23456
open
23456
112233
12345
open
12345
LOOKUPVALUE is not compatible in DAX measure. You can replace it with following.
_return =
VAR _1 =
MAX ( 'fact'[Group_ID] )
VAR _2 =
CALCULATE (
MAX ( 'fact'[ID] ),
ALL ( 'fact' ),
FILTER ( VALUES ( 'fact'[Group_ID] ), 'fact'[Group_ID] = _1 )
)
RETURN
_2
A simpler way of calculating this is by using ALLEXCEPT() in a measure like so:
Measure =
CALCULATE (
MAX ( 'Table'[ID] ) ,
ALLEXCEPT ( 'Table' , 'Table'[Group_ID] )
)
This yields the same result as #smpa01 but is a much more performant measure, around 30-40% quicker on this data set, according to DAX Studio analysis.

How to modify DAX ALLEXCEPT to allow filtering

I have a Table called Tracking, as shown below:
Category
Item Id
Work Date
A
1
1/1/2020
B
1
2/1/2020
C
1
3/1/2020
D
1
4/1/2020
A
2
7/1/2020
B
2
8/1/2020
C
2
9/1/2020
D
2
10/1/2020
Using the below measure, I can get Maximum Work Date from the above Table.
maxWorkDate =
CALCULATE (
MAX ( 'Tracking'[Work Date] ),
ALLEXCEPT (
'Tracking',
'Tracking'[Item Id]
)
)
For Item 1, the maximum work date is 4/1/2020 and for Item 2, the maximum work date is 10/1/2020.
I want to get maximum work date by Excluding Category D. So, For Item 1, the maximum work date should be 3/1/2020 and for Item 2, the maximum work date should be 9/1/2020.
I would like to exclude category D within the measure or I can also exclude it in Visual Filters. Please advise. Thanks
It's possible to implement the measure with a filter expression 'Tracking'[Category] <> "D" like follows
maxWorkDate =
CALCULATE(
MAX( 'Tracking'[Work Date] ),
REMOVEFILTERS( 'Tracking' ),
VALUES( 'Tracking'[Item Id] ),
'Tracking'[Category] <> "D"
)
This is what FILTER is for:
maxWorkDate =
CALCULATE (
MAX ( 'Tracking'[Work Date] ),
FILTER (
ALLEXCEPT (
'Tracking',
'Tracking'[Item Id]
),
'Tracking'[Category] <> "D"
)
)

Count how many sub-activities were created based on an activity

I have a dimension that stores workflows(cases, subcases). I would like to do a count of how many subcases are created for each case.
Workflow Dimension
Workflow
------------------------------
Case Number WorkflowType
------------------------------
10 Case
20 Case
30 Case
20-1 Subcase
20-2 Subcase
20-3 Subcase
10-1 Subcase
The desire output I would like is, for every case count how many subcases were created.
Workflow
------------------------------------------------
Case Number WorkflowType CountOfSubcases
------------------------------------------------
10 Case 1
20 Case 3
30 Case 0
------------------------------------------------
Total 4
I have a current dax measure that works, but the total at the bottom does not show when looking at multiple rows, only display when one case is selected.
Total Subcases =
VAR CC = FIRSTNONBLANK ( Workflow[Case Number], 1 )
RETURN
COUNTX (
FILTER (
ALL( Workflow ),
SUBSTITUTE ( Workflow[Case Number], RIGHT ( Workflow[Case Number], 2
), "" )
= CC
&& Workflow[WorkflowType] = "SubCase"
),
Workflow[WorkflowID]
)
If anybody could help me tweak my measure or present with a new measure, that would be great.
Note: I'm pointing my report to Analysis Services.
Thanks in advance.
You can fix your measure as follows:
Total Subcases = 0 +
COUNTX (
FILTER (
ALL( Workflow ),
SUBSTITUTE ( Workflow[Case Number], RIGHT ( Workflow[Case Number], 2 ), "" )
IN VALUES( Workflow[Case Number] )
&& Workflow[WorkflowType] = "SubCase"
),
Workflow[WorkflowID]
)
The VALUES function returns a list of all the values in the current filter context instead of just the one you were picking before.
Note: To make things easier to work with, I'd suggest splitting the Case Number column into two columns in the query editor stage. Then you don't have to work with all the string manipulation.
Edit: Note that x IN <Table[column]> is equivalent to the older CONTAINS syntax:
CONTAINS(Table, [column], x)
So if you can't use IN then try this formulation:
Total Subcases = 0 +
COUNTX (
FILTER (
ALL( Workflow ),
CONTAINS(
VALUES( Workflow[Case Number] ),
Workflow[Case Number],
SUBSTITUTE ( Workflow[Case Number],
RIGHT ( Workflow[Case Number], 2 ), "" )
)
&& Workflow[WorkflowType] = "SubCase"
),
Workflow[WorkflowID]
)

DAX Year over Year

I have been trying to get this DAX expression to show me cumulative searches for last financial year. Here is an example of the information;
Fiscal Week Fiscal Year Searches Brand
1 14 1000 Example1
1 15 1200 Example1
2 14 1000 Example1
2 15 1200 Example2
My formula below is working a little, but when I apply an slicers to the data it breaks in PowerBI. i.e. if I slice by another field, like brand.
Cum. Searches PY =
IF (
HASONEVALUE ( 'data'[Fiscal Year] ),
CALCULATE (
SUM ( 'data'[Searches] ),
FILTER (
ALL( 'data' ),
'data'[Fiscal Year.] = VALUES ( 'data'[Fiscal Year] ) - 1
&& CONTAINS(
VALUES ( 'data'[Fiscal Week] ),
'data'[Fiscal Week],
'data'[Fiscal Week] )
)
),
BLANK ()
)
I'd appreciate any pointers to where I'm going wrong? Thanks in advance.
I think it can be simplified, I dont understand the need for the HASONEVALUE or CONTAINS functions. I would use something like the following for your measure:
Cum. Searches PY:= CALCULATE(
SUM( Table1[Searches] ),
FILTER(
ALL( Table1[Fiscal Year] ) ,
Table1[Fiscal Year] = MAX( Table1[Fiscal Year] ) - 1
)
)
With that sample data above, this will produce results of:
Example1 2000
Example2 (Blank)
If that's not your expected result, then explain exactly what you want.
