DATEDIFF between DateTime Values by ID
I have a Table_A, which tracks the DateTime of status changes.
| DateTime | ID | Entry | Exit |
| 29/10/2020 14:25 | 1001 | 1 | 0 |
| 01/12/2020 15:30 | 1002 | 1 | 0 |
| 05/02/2021 12:00 | 1001 | 0 | 1 |
| 15/04/2021 21:45 | 1002 | 0 | 1 |
I want to calculate the amount of time between Entry and Exit for each ID (TimeSpent).
| DateTime | ID | Entry | Exit | TimeSpent |
| 29/10/2020 14:25 | 1001 | 1 | 0 | null |
| 01/12/2020 15:30 | 1002 | 1 | 0 | null |
| 05/02/2021 12:00 | 1001 | 0 | 1 | 99 |
| 15/04/2021 21:45 | 1002 | 0 | 1 | 135 |
Something like this
TimeSpent =
DATEDIFF(
FILTER('TableA'[DateTime], Entry = 1),
FILTER('TableA'[DateTime], Exit = 1),
Day
)
I get the following error message "The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value."
I doubt very much that FILTER is the right way to identify cases for the calculation... I've tried CALCULATE but that didn't work either.
Any ideas?

Anonymous , Try a measure like
averageX(values(Table[ID]), calculate(datediff(minx(filter(Table, Table[Entry] =1), [DateTime]),maxx(filter(Table, Table[exit] =1), [DateTime]),minute)))

Hi Amitchandak,
Is it possible to filter this measure [TimeSpent] by a Date table 'Date'?
You would need to specify in the Measure that the filter applies to the Exit DateTime. Or possibly ignore the lesser date with something like ...FILTER(ALL('Date'[DateTime]),'Date'[DateTime]<=MAX('Date'[DateTime]))
Hi, Anonymous
Please check the below picture and the sample pbix file's link down below.
Time Spent Measure =VAR currentid =MAX ( 'Table'[ID] )VAR entrydatetime =CALCULATE (MAX ( 'Table'[DateTime] ),FILTER ( ALL ( 'Table' ), 'Table'[ID] = currentid && 'Table'[Entry] = 1 ))RETURNIF (ISFILTERED ( 'Table'[ID] ),IF (SELECTEDVALUE ( 'Table'[Exit] ) = 1,DATEDIFF ( entrydatetime, SELECTEDVALUE ( 'Table'[DateTime] ), DAY ),"null"))Hi, My name is Jihwan Kim.

Hi, Anonymous
Thank you for your feedback.
in my sample, ID is a number format.
If your ID column is a text format, please try writing something like below.
"1" "2" ...
Thank you.
