Creating a Custom Column from CurrentDate - powerbi

I'm trying to create a new custom column from a conditional statement and current date.
Next picture explains exactly what i need to get with power query.
An example of what I need from pseudocode is:
if [fecha fin de plazo]>=CurrentDate and [fecha CIERRE investigación]=null
then "string"
My biggest problem is I don't know how to extract the current date with PowerQuery.

You could try using,
if [fecha fin de plazo]>= DateTime.LocalNow() and [fecha CIERRE investigación]=null
then "string"
DateTime.LocalNow()

Using the DateTime.LocalNow you get the date and time of your system, the problem is at time to compareting the date value with the result of DateTime.LocalNow() becsause you need to compare only dates.
That's why It must use DateTime.Date. This fucntion returns the date component of DateTime.LocalNow().
if [date1] >= DateTime.Date(DateTime.LocalNow()) and [date2]=null
then "string"
You can get more information about this functions here:
DateTime.LocalNow()DateTime.Date()

Power BI - Creating a calculated table

I am creating a dashboard in Power BI. I have to report the executions of a process in a daily basis. When selecting one of these days, I want to create another calculated table based on the day selected (providing concrete information about the number of executions and hours) as it follows:
TABLE_B = FILTER(TABLE_A; TABLE_A[EXEC_DATE] = [dateSelected])
When [dateSelected] is previously calculated from the selected day as it follows:
dateSelected = FORMAT(FIRSTDATE(TABLE_A[EXEC_DATE]);"dd/MM/yyyy")
I tried a lot of alternatives as, for example, create individualy the year, month and day to later compare. I used the format in both sides of the comparation, but none of them works for me. The most of the cases it returns me the whole source table without any kind of filters. In other cases, it doesn't return anything. But, when I put a concrete day ...
TABLE_B = FILTER(TABLE_A; TABLE_A[EXEC_DATE] = "20/02/2019")
... it makes the filter correctly generating the table as I want.
Does someone know how to implement the functionality I am searching for?
Thanks in advance.
You're almost there Juan. You simply need to use dateSelected as a varialbe inside of your DAX query:
TABLE_B =
var dateSelected = FIRSTDATE(TABLE_A[EXEC_DATE])
return
FILTER(TABLE_A, TABLE_A[EXEC_DATE] = dateSelected)
Note that all my dates are formatted as Date so I didn't need to use a FORMAT function.
Here's the final result:
I admit that this behavior can be quite confusing! Here is a useful link that will help you understand Power BI's context:
https://community.powerbi.com/t5/Desktop/Filtering-table-by-measures/td-p/131361
Let's treat option 1 as FILTER(TABLE_A; TABLE_A[EXEC_DATE] = "20/02/2019") and option 2 as FILTER(TABLE_A; TABLE_A[EXEC_DATE] = [dateSelected]). Quote from the post:
In option 1, in the filter function, you are iterating
over each row of your 'Table' (row context). In option 2, because you
are using a measure as part of the filter condition, this row context
is transformed into an equivalent filter context (context transition).
Using variables (...) is very convenient when you want to filter
a column based on the value of a measure but you don't want context
transition to apply.

How to create a new column converting date to text

I need to create a new column with an IF.
If the difference between two dates is more than a month I have to use a text-like "much time" but if it is not I have to show a date.
So the date must be converted to a string to use a text column.
How can I convert date to text?
Fecha_real =
IF( DATEDIFF(ventas[fecha_pedido]; ventas[fecha]; month) = 1 ;
"much time";
ConvertToTextInSomeWay ventas[fecha]
)
This is pretty simple with the FORMAT function.. For example, FORMAT(ventas[fecha], "Short Date") will convert fecha into textlike "12/31/2018".
That's just one format example. There are plenty of pre-defined and custom options if you'd rather something else. For example, FORMAT(ventas[fecha], "dd-mm-yyyy") would format that same date as "31-12-2018" instead.

Date comparison in power bi dax

I had a problem with my code. It returns the below error:
DAX comparison operates do not support comparing values of type date with values of type text.
Basically, I want to count rows based on some conditions. And I know there is a need to convert the data type, but I am not sure how to do it.
Total Open Issues =
--------------------
--basic info
VAR SELECTEDDATE =
DATEVALUE(SELECTEDVALUE(Calender[FullDateAlternateKey].[Date]))
--------------------
--FIND the relvent data
VAR rlvttable =
calculatetable(
Tracker,
Tracker[Catagory]="ISSUE",
DATEVALUE(Tracker[ClosedDate])>SELECTEDDATE
||Tracker[ClosedDate]=""
)
--------------------
--Results
Return
countrows(rlvttable)
Anyone could advise me how to correct it? Thanks~
Check the data type of columns Tracker[ClosedDate] and Calender[FullDateAlternateKey] - one of them is Text, rather than Date.
To fix, you could:
choose a different field which is already a Date format
change the format of the offending column
use DATEVALUE in your measure, to convert the text date to a real date.
It also looks like you need to edit this statement, as these conditions conflict:
Tracker[ClosedDate]>SELECTEDDATE
&&Tracker[ClosedDate]=""
I am trying to compare the closedDate with "". I should use blank() instead.

PowerBI/DAX: Unable to correctly compare two dates

I have this custom date that I created as a measure:
Start Date = DATE(YEAR(MAX(Loss[dte_month_end]))-1,12,31)
So this part looks fine in PowerBI and seems to be the right format.
So now I created a new column where I'm going through my data to check whether a record is equal to my "Start Date" as defined above.
IsStart = IF(Loss[dte_month_end]=[Start Date], TRUE, FALSE)
but the weird thing is that all records are evaluated to false.
I know this is actually not the case in my actual data, and I could find actual records with dte_month_end = 12/31/2017 as shown above.
Can someone help me understand why the IF statement would not be able to evaluate this correctly? I initially thought that this may be a case of the DATETIME format being inconsistent - but I purposefully changed both formats to be the same to no avail.
Thanks.
Edit1----------- FYI:
This is the format that my dte_month_end field has:
Edit2 --
I tried changing the dte_month_end format to Date instead of DateTime, and it still doesn't seem to work:
This is happening because you are using a measure inside of a calculated column. When you do this, the filter context for the measure is the row context in the table.
To fix this, you need to modify the filter context for your measure. For example:
Start Date = DATE(YEAR(CALCULATE(MAX(Loss[dte_month_end]), ALL(Loss))) - 1, 12, 31)
or
Start Date = DATE(YEAR(MAXX(ALL(Loss), Loss[dte_month_end])) - 1, 12, 31)
If you don't do this, the MAX only looks at the current row, rather than all the rows in the table.

Sharepoint calculated column based on other columns #NULL! error

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.
