Problem with cumulative percentages

Hi all! I have a table with some information about when workers validate some information. It has the following colummns:

Division: the division to which the worker belongs.

Department: the department to which the worker belongs.

User_code: the worker's user code.

Document_date: the date of document

Validation_date: the date on which the worker validates the document

Day: the day on which the worker validates the document. It is the result of the subtraction of the two date columns.

Lack of validation: If the worker has validated the document, "NO" will be displayed. If not, the field will be blank.

Based on this information, I am trying to create a graph/table showing the evolution of the validation percentage distributed by days ("Day" column).

So I made this measures: (note that every row is a document that should be validated)

Total validated documents = CALCULATE(COUNTROWS(Hoja1),Hoja1[LACK OF VALIDATION] = "NO")  -- in order to calculate the number of validated documents.

 

Total documents = COUNTROWS(Hoja1)

 

% validate documents = DIVIDE([Total validated documents], CALCULATE([Total documents], ALLSELECTED(Hoja1)))

 

Cumulative % of validation =

CALCULATE(

    [% validate documents],

    FILTER(

ALLSELECTED('Hoja1'[DAY_OF_VALIDATION]),

        ISONORAFTER('Hoja1'[DAY_OF_VALIDATION], MAX('Hoja1'[DAY_OF_VALIDATION]), DESC)

    )

)

 

So I've created a table with this measures but the result is not what I looking for:

 

 

In the % cumulative validation is not making the addition properly.

 

Also If I filter the table by the column "Division" the result in not correct.

 

Could you please help me??

 

Thanks in advanced. I've attached the .pbix
