what is the difference between All and AllSelected?

@SandipGhosh - ALL removes all filters. ALLSELECTED removes filters inside the query but not those outside the query. Read up on ALLSELECTED before using it:

Hi, Is there any difference between

COUNTX(ALL(columnA)), columnA) and 

COUNTX(ALL(tableA)), columnA)

, but I did not understand the 

https://www.sqlbi.com/articles/the-definitive-guide-to-allselected/

it is very complex and lenthy for me.

Hi @SandipGhosh ,

The first formula, ALL removes any active filters from the columnA.

The second formula, ALL returns a table containing all columns.

About ALL and ALLSELECTED, we can create a sample to help you understand.

We want to calculate the total value of the name. So we create two measures, one uses ALL, another uses ALLSELECTED.

ALL function calculates the Total = CALCULATE(SUM('Table'[value]),ALL('Table'))

ALLSELECTED calculates the Total = CALCULATE(SUM('Table'[value]),ALLSELECTED('Table'))

We can see there is no difference between the last two measures, they are both 10.

Now we add a slicer based on Name and select A and B.

The rows become two, and the ALLSELECTED measure changed.

Because the ALLSELECTED function is affected by external filters, the Name slicer is one of external filters.

But the ALL function is not affected by external filters.

If you want to calculate the total that will not change, you can use ALL.

If you want to calculate the total that will change according to the slicer, you can use ALLSELECTED.

Maybe you can refer the following video, video explanation may help you.

@SandipGhosh let's assume you have a date table starting Jan 01st, 2019 and dec, 31st, 2020 and you have put a slicer on the date column and in slicer, you selected Jan 01st, 2020 to Aug 31st, 2020 

if you use ALL function in your measure, it will ignore the filter and all the dates.

if you use ALLSELECTED function in your measure, it will give you a full range of selected dates.

All Measure = CALCULATE ( SUM (Table[Amount] ) , ALL ( DateTable ) )

Allselected Measure = CALCULATE ( SUM ( Table[Amount], ALLSELECTED( DateTabe ) )

Assuming you have $100000 sales in 2019, 2020, and from Jan 01st, 2020 to Aug 31st, 2020 (Slicer selection), sales is $20000

if you add a table visual and date from the date table and above two measures, for each date, for ALL Meaasure you will get the value of $100000 and for ALLselected measure you will get the value of $20000
