## Calculate Duration Dynamically Hi,

Im trying to calculate the duration of an event over time in Power BI, The screenshot above is a sample of the data, what I need to do is calculate how long was spent in Status A,B,C etc. but as you can see the status can change back and forth in the data, so id need to calculate how long a duration it spent in each status but it needs to take into account the status changes , because if i was just to filter it to status A for example theres jumps in Time and vise verca so just summing that up alone wouldnt take into account that it has changed status multiple times within the day and there are time jumps which skew the results or make them look longer than it has actuually spent.

The overall aim to create a small sumary chart summing how long in total each status lasted.

In the example above it would need to be something like this:

Status       Total Time Spent (minutes)

A               15

B               5

C               4

D              0

E               5

F               0

This would be straightforward to do it in excel however I have many scenarios to do it for so a dynamic solution would be preffered .

Thanks

Hi @Sher

Below is a simplified sample for your reference.

`IF = IF(Table1[Status]=LOOKUPVALUE(Table1[Status],Table1[Index],Table1[Index]-1),0,1)`
`Group = SUMX(FILTER ( Table1, Table1[Index] <= EARLIER ( Table1[Index] ) ),Table1[IF])`
```DiffTime =
CALCULATE (
DATEDIFF ( MIN ( Table1[DateTime] ), MAX ( Table1[DateTime] ), MINUTE ),
ALLEXCEPT ( Table1, Table1[Group] )
)```

Then you may get the table as below:

`Table = SUMMARIZE(Table1,Table1[Status],Table1[DiffTime])` Regards,

## Re: Calculate Duration Dynamically

One approach is to create an index column, then use some conditional logic - say if the statuses are different, then it's zero, otherwise it's the difference in datetime values between this row and the previous row. There's a few threads on this if you search

## Re: Calculate Duration Dynamically

Hi @v-cherch-msft  , I have got around to trying this and it has worked more or less spot on. Thank you for your help on this.

What if I was to introduce another variable (See Screenshot below) The appliance. anf therefore wanted to do the same as before but have a total for the time spent in each status but this time for each appliance. Is this possible?
