I'm trying to Add Custom Column in Power Query with the objective to return a Table from a List of dates.
The syntax used is as follows below:
= Table.AddColumn(TypeDate, "AddTable", each Table.FromList(
List.Dates([Date_begin],1,#duration(1,0,0,0)
)))
where:
TypeDate is the name of last step in Power Query
"AddTable" is the name of added custom column
[Date_begin] is a column with dates to be considered as the start of my list
Although the syntax seems correct, Power Query returns an error described as follows:
Expression.Error: We could not convert the value #date(2021, 1, 1) on to Text.
Details:
Value=01/01/2021
Type=[Type]
Does anyone know how to handle this problem?
I'll show an image where Power Query shows the error.

Your question is unclear
You want to add a column that has a table of dates for each row, using Date_Begin and Mes_Final?
#"Added Custom" = Table.AddColumn(TypeDate, "AddTable", each Table.TransformColumnTypes(Table.FromList({Number.From([Date_Begin])..Number.From([Mes_Final])}, Splitter.SplitByNothing(), {"date"}),{{"date", type date}}))

I am working on a Power BI report and I am using a parquet file as the source. I have this column that holds info about the month:
As you see here, in MONTH_RUN, I have the data stored both as "202201" (yyyymm format) and "12/1/2021" (more like a date format).
I would need to change the values that appears like this: "12/1/2021" to "202112", so I can have all the values the same format.
I need to do this in a dynamic way, like searching for the rows that has values containing "/" character and based on that to change it into "yyyymm" format.
Is this possible?
I'm kinda new with power query and idk how should I implement this, but I would prefer to do it without creating any other additional columns.
Please, do not post sample data as images. It makes it difficult to answer your question.
One way to deal with this is to add a custom column, where the value will be either the same as MONTH_RUN (if it doesn't contain /), or it will parse the text to date, and then format it accordingly. For example:
if Text.Contains([MONTH_RUN], "/") then
Date.ToText(Date.FromText([MONTH_RUN], [Format="M/d/yyyy", Culture="en-US"]), [Format="yyyyMM", Culture="en-US"])
else
[MONTH_RUN]
Then use this custom column in your report.
I would just delete the existing MONTH_RUN column and create a new one based on the date in the DAY_RUN column.
eg:
#"Removed Columns" = Table.RemoveColumns(#"Changed Type",{"MONTH_RUN"}),
#"Added Custom" = Table.AddColumn(#"Removed Columns", "MONTH_RUN", each Date.ToText([DAY_RUN],"yyyyMM"), type text)

How to make a calculations in Power Bi using whole list for all rows. I tried to do this way
but I got error "A cyclic reference was encountered during evaluation". Is this a way to put whole column in calculated fields and make with it some calculations?
This is my table
My desire is for example if(OrderID{index}="A" then Shippedwwo{index} else Shippedowo{index -1} like in a picture below.
To get your posted output, there is no need for the Index column (or for a custom function, for that matter).
#"Added Custom" = Table.AddColumn(previousStep, "test_column",
each if [Action]="A" then [Assignwwo] else null),
#"Filled Down" = Table.FillDown(#"Added Custom",{"test_column"})
orig data

The picture I have attached shows what my power query table looks like (exactly the same as source file) and then underneath what I would like the final end product to look like.
Correct me if I'm wrong but I thought the purpose of power query/power bi was to not manipulate the source file but do this in power query/power bi?
If that's the case, how can I enter new columns and data to the existing table below?
You can add custom columns without manipulating source file in power bi. Please refer to below link.

EDIT: Based on your comment editing my answer - Not sure if this helps.
Click on edit queries after loading source file to power bi.
Using 'Enter Data' button entered sample data you provided and created new table. Data can be copy pasted from excel. You can enter new rows manually. Using Tag number column to keep reference.
Merge Queries - Once the above table is created merged it with original table on tag number column.
Expand Table - In the original table expand the merged table. Uncheck tag number(as it is already present) and uncheck use original column name as prefix.
Now the table will look like the way you wanted it.
You can always change data(add new columns/rows) manually in new table by clicking on gear button next to source.
Here is the closest solution to what I found from "manual data entry" letting you as much freedom as you would like to add rows of data, if the columns that you want to create do not follow a specific pattern.
I used an example for the column "Mob". I have not exactly reproduced the content of your cells but I hope that this will not be an issue to understand the logic.
Here is the data I am starting with:
Here is the Power Query in which I "manually" add a row:
#"Added Conditional Column" = Table.AddColumn(#"Changed Type", "Mob", each if [Tag Number] = "v" then null else null),
NewRows = Table.InsertRows(#"Added Conditional Column", 2, {[Mob="15-OHIO", Tag Number="4353654", Electronic ID=1.5, NLIS="", Date="31/05/2015", Live Weight="6", Draft="", Condition store="", Weighing Type="WEAN"]})
in
NewRows
1) I first created a column with only null values:
#"Added Conditional Column" = Table.AddColumn(#"Changed Type", "Mob", each if [Tag Number] = "v" then null else null),
2) With the "Table.InsertRows" function:
I indicated the specific line: 2, (knowing that power Bi start counting at zero, at the "headers" so it will the third line in the file)
I indicated the column at which I wanted to insert the value, i.e "Mob"
I indicated the value that all other other rows should have:
NewRows = Table.InsertRows(#"Added Conditional Column", 2, {[Mob="15-OHIO", Tag Number="4353654", Electronic ID=1.5, NLIS="", Date="31/05/2015", Live Weight="6", Draft="", Condition store="", Weighing Type="WEAN"]})
Here is the result:
I hope this helps.
You can apply this logic for all the other rows.
I do not think that this is very scalable however, becaue you have to indicate each time the values of the rows in the other columns as well. There might be a better option.
I have my data source something like below.
I need to show output in the report as below.
I tried using the unpivot column and getting something like this, how to count the occurrence value of each Business value.
Plot following mesure against Value column (from your unpivot table):
Business Occurance = COUNTROWS('your unpivot table')
We have to remove the Attribute column as the next step to Unpivot. Then my table should be looks like this.
Now create a new table with following Dax function, let's say the current table as Business Data (Your Unpivot table)
Occurrence Table = DISTINCT('Business Data')
Now end result table should look like this,
You can make use of this table for your table visual in the report.
Note: You can add n-number of rows and column into your source table and this logic will do magic to get the correct result.
I have marked two places first marked place you have to add Value column then click second marked place one dropdown value is open click count menu
I am trying to add two currency columns in a calculated column but am getting a #NULL! error.
This seems pretty straightforward but its my first time doing this in SharePoint.
SharePoint 2010 with Excel Services available.
Have create List with required columns:
Approved Value column Type = Currency
Pending Value column Type = Currency
Total Value column
Calculated (calculation based on other columns)
Type = Currency
Formula: =[Approved Value]+[Pending Value]
The values in other columns are indeed currency, but the Total shows #NULL! for all items.
I can't see anything done incorrectly.
What should I be looking for to resolve this problem?
Try using the ISBLANK function to previously check if any of the value is null.
Reference: ISBLANK function
I ended up using NZ(Value, 0)
=NZ([Approved Value],0)+NZ([Pending Value],0)
Though not sure how NULLs ended up in field or why SharePoint couldn't deal with them without this special treatment.
