i need help sorting columns in named sets created in power pivot
-data source is just plain .txt files on sharepoint
for example i have named set
{([Measures].[Sum of broj_stavki_KKPPL]),
([Measures].[prosečan broj iskomisioniranih stavki KP i PL]),
([Measures].[procenat učinka komisionara na KP i PL])}
and i need formula to sort second column or even better if i can get multiple sort for all columns
i have tried to use function ORDER but as i'm new to MDX function i just can get it right

I am trying to figure out how to change 2 columns of data into one header row with multiple columns in Excel Power Query. It's my understanding that Query keeps the Excel file size small, and is less on the processes, as opposed to using tons of vlookups or pivot tables. I'm open to VBA if that's a better option.
For example, I have Column A with a list of names. Then, column B has another list of names with multiple instances of the same name(s). The names in column A are individuals assigned to report to individuals in B.
I'm trying to create a query (or VBA if better) where the names in B become the row headers, and the names in A fall under the corresponding person in each header.
I hope that makes sense. Thank you in advance for your help!
Here's a screenshot, demonstrating what I'm working with, and the end result I'm trying to get:
You can use Power Query:
let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
ListEmployees = Table.Group(Source, {"Supervisor Name"}, {{"Employees", each Text.Combine([Employee Name],","), type text}}),
CountEmployees = Table.AddColumn(ListEmployees, "Count", each List.Count(Text.Split([Employees],","))),
SplitEmployees = Table.SplitColumn(ListEmployees, "Employees", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv),List.Max(CountEmployees[Count])),
Transpose = Table.Transpose(SplitEmployees),
PromoteHeaders = Table.PromoteHeaders(Transpose, [PromoteAllScalars=true])
in
PromoteHeaders
Make sure your source data is structured as a Table (listobject).
How to write this expression in PowerBI
select distinct([date]),Temperature from Device47A8F where Temperature>25
Totally new to PowerBI. Is there any tool that can change the query from sql to PowerBI expression?
I have tried so many type of different type of expressions but getting error, Most of the time I am getting this:
The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.
Need help, Thanks.
After I posted my answer, wondered if your expected result is get only one date by temperature, In other words, without repeated dates in your result set.
A side note: select distinct([date]),Temperature from Device47A8F where Temperature>25 returns repeated dates since DISTINCT keyword evaluate distinct columns values specified in the SELECT statement, it doesn't return distinct values in a specific column even if you surround it with parenthesis.
Now what brings us here. What I can see in your error is that you are trying to use a table-valued (produces a table with multiple columns) expression in a measure which only accepts scalar-valued (calculate only one value).
Supposing you have a table like this:
Running your SQL query you will get the highlighted in yellow rows:
You can see 01/09/2016 date is repeated. If you want to create a measure you have to define what calculation you want to show for temperature. i.e, average, max or min etc.
In the below expression is being calculated the maximum temperature greater than 25 per date:
MaxTempGreaterThan25 =
CALCULATE ( MAX ( Device47A8F[Temperature] ), Device47A8F[Temperature] > 25 )
In this case the measure MaxTempGreaterThan25 is calculated per date.
If you don't want to produce a measure but a table. In the Power BI Tool bar select Modeling tab and click New Table icon.
Use this expression:
MyTemperatureTable =
FILTER ( Device47A8F, Device47A8F[Temperature] > 25 )
It should produce a new table named MyTemperatureTable like this:
I recommend you learn some basics about DAX, it is pretty different from SQL / T-SQL and there are things you can't do depending on your model and data.
Let me know if this helps.
You probably don't need to write any code if your objective is to show the result in a Power BI visual e.g. a table. Power BI naturally aggregates data if the datatype is numeric (e.g. Temperature).
I would just add a Table visual on a Report page and add the Date and Temperature columns to it. Then in Visualizations / Fields / Values I would click the little down-arrow on the Temperature field and set the Aggregation e.g. Maximum. Then in Visualizations / Fields / Filters I would click the little down-arrow on the Temperature field and set the Filter e.g. is greater than: 25
Hard-coded solutions are unlikely to survive the next question from your users e.g. "but what if I want to see Temperature > 24? Or 20? Or 30?"
Im new (couple of days to be exact) on Cubes, I have the following problem.
I have a Measure that brings certain amount of data, 100 rows for example. From that data I want to filter numbers that are < 0 from one of its columns.
For example this measure:
[Measures].[Distribution CSU Groups]
Will bring data like this
enter image description here
As you can see in the link, I want to filter those rows that have negative values on the 3rd column.
Is it possible to do this via MDX and how?
Yes filtering is possible in mdx via the following functions:
IIF function
FILTER function
HAVING clause
Any idea how to summarize data in a Pentaho transformation and then insert the summary row directly under the group being summarized.
I can use a Group By step and get a summarised result stream having one row per key field, but what I want is each sorted group written to the output and the summary row inserted underneath, thus preserving the input.
In the Group By, you can do 'Include all Rows', but this just appends the summary fields to the end of each existing row. It does not create new summary rows.
Thanks in advance
To get the summary rows to appear under the group by blocks you have to use some tricks, such as introducing a numeric "order" field, setting the value of the original data to 1 and the sub totals rows to 2.
Also in the group-by/ sub-totals stream, I am generating a sum field, say "subtotal". You have to make sure to also include this as a blank in your regular stream or else the metadata will be divergent and the final merge will not work.
Here is the best explanation I have found for this pattern:

You will need to copy the rows too a different stream, and then merge or join them again, to make it a separate row.
Here's an annoying issue. I've got a pivot table in an Excel spreadsheet which gets its data direct from a SQL server query.
The table has customers on the vertical axis, and dates on the horizontal access. Both need to be correctly sorted - i.e. customers as alphabetical top to bottom and dates in date order from left to right.
I've ensured that the data coming out of SQL is recognised by EXcel as a date field. You can sort the dates successfully using the manual A-Z function. But I need to do it automatically using VBA.
I had hoped (againt hope) that using two sorting parameters on the SQL query might do the trick:
sql = "SELECT * FROM myView ORDER BY Customer, Date"
Set pt = Worksheets("MyReport").PivotTables("MyPivot")
pt.PivotCache.CommandText = sql
pt.RefreshTable
But it doesn't.
I see than in Excel 2010 onwards there's a handy AutoSort function that should do what I need. But I'm stuck with 2007. Is there a way to sort my data in both dimensions?
Turns out there is an AutoSort feature in Excel 2007, but it belongs to the PivotFields object, rather than the pivot table itself.
Dim pt As PivotTable
Set pt = Worksheets("myWorksheet").PivotTables("myPivotTable")
pt.PivotFields("DATE").AutoSort xlAscending, "DATE"
