Adjusting percentages based on filter

[BruceSV]

I have a measure that calculates the percentage of column_numbers based on a selection which works on the total data when using specific boolean type filter based on column_boolean. The measure is as follows:

percentage = (DIVIDE(SUM(data[column_numbers]),CALCULATE(SUM(data[column_numbers]),ALL(data))))*100

However, I also have a column_dates in my dataset. When I select a specific month I want it to display the percentage of that specific month, and not the included records as a percentage of a whole. 

Example of dataset:

column_dates	column_numbers	column_boolean
Jan	1	true
Jan	2	false
Feb	3	true
Feb	4	false
Mar	5	true
Mar	0	false

Outcome examples:

selection 1: column_dates = all, column_boolean = true

expected outcome 1: 53% (calculation: 1 + 3 + 5 / 15)

selection 2: column_dates = Jan, column_boolean = true

expected outcome 2: 33% (1 / 3)

selection 3: column_dates = Jan & Mar, column_boolean = true

expected outcome 3: 75% (1 + 5 / 😎

With the current measure only selection 1 provides the correct result.

Thank you for your answer. Didn't know about the removefilters() function. Will need to do some research on it. 

Thanks again.

@BruceSV 

pls  try this

Measure = DIVIDE(sum('Table'[column_numbers]),CALCULATE(sum('Table'[column_numbers]),REMOVEFILTERS('Table'[column_boolean])))
