Days between dates column not correctly computing

Hello


I am running two columns which cacluate days between dates and both are throwing incorrect results

 

Time to Close RFIs = IF(ISBLANK(RFIs[ANSWERED_DATE]),BLANK(),(RFIs[ANSWERED_DATE]-RFIs[SUBMITTED_DATE])*1.)

 

Lapse Days=Time to Close RFIs = IF([ANSWERED_DATE]> [Required Date],[ANSWERED_DATE]-[Required_DATE])*1.0,Blank())

Re: Days between dates column not correctly computing

Recreated your table and created two different calculated columns with the same results

 

datediff =
IF (
    DATEDIFF ( 'Table2'[RequiredDate], Table2[AnswerDate], DAY ) > 0,
    -1 * ( DATEDIFF ( 'Table2'[RequiredDate], Table2[AnswerDate], DAY ) ),
    DATEDIFF ( 'Table2'[RequiredDate], Table2[AnswerDate], DAY )
)

where

  • 'Table2' should be replaced with your table and
  • RequiredDate is PMSCRFI_ANSWERED_DATE and
  • AnswerDate is PMSCRFI_REQUIRED_DATE

Another Calculated column

datediff 2 =
IF (
    Table2[RequiredDate] < Table2[AnswerDate],
    -1 * DATEDIFF ( 'Table2'[RequiredDate], Table2[AnswerDate], DAY ),
    DATEDIFF ( 'Table2'[RequiredDate], Table2[AnswerDate], DAY )
)

These give the same result

Re: Days between dates column not correctly computing

Have you tried using the DATEDIFF function instead?

Re: Days between dates column not correctly computing

I tried but doesnt help

 

Time to Resolve = SWITCH(TRUE(),RFIs[PMSCRFI_REQUIRED_DATE]<RFIs[PMSCRFI_ANSWERED_DATE],-1*DATEDIFF(RFIs[PMSCRFI_REQUIRED_DATE],RFIs[PMSCRFI_ANSWERED_DATE],DAY),RFIs[PMSCRFI_REQUIRED_DATE]>RFIs[PMSCRFI_ANSWERED_DATE],DATEDIFF(RFIs[PMSCRFI_ANSWERED_DATE],RFIs[PMSCRFI_REQUIRED_DATE],DAY),0)

Re: Days between dates column not correctly computing

Can you share some sample data, what result you are getting and what result you are expecting?

Re: Days between dates column not correctly computing

The formula does look like it produces the correct answer sometimes, but not all the time.

 

In your table, are you summarizing your Date fields in any way?  For example are you showing "First" or "Last" date for any reason?  I'm wondering if your data is in such a way that your formula is calculating using a different context to how your matrix is displaying the rows.

Re: Days between dates column not correctly computing

Thanks everyone for stepping in

 

Both your answers were correct

 

Yes my filter context in the table was incorrect which was giving inconsistent results

 

The forumlas provided below work great too
