Time status
Hi all,
I have data that looks like this:
| Date | Time | Status |
| 1899-10-12 | 02:40:00 | M |
| 1899-10-12 | 02:40:50 | M |
| 1899-10-12 | 02:41:21 | X |
| 1899-10-12 | 02:41:56 | X |
| 1899-10-12 | 02:42:34 | X |
| 1899-10-12 | 02:43:01 | M |
| 1899-10-12 | 02:44:21 | M |
| 1899-10-12 | 02:44:59 | X |
| 1899-10-12 | 02:45:46 | X |
| 1899-10-12 | 02:46:38 | M |
Now what I want to do is to calculate how much time the status was "X" and so I would need to calculate the time between the first record that has X till the last record that has X with no other status then X between them. So for example in my dummy data you can see that this happens 2 times: 02:41:21 until --> 02:42:34 And 02:44:59 until --> 02:45:46.
So my expected result would be: 00:01:13 + 00:00:47 = 00:02:00 X status
I hope the above is understandable, thanks in advance !

Revised solution below. You can create a new - blank - query, go to the advanced editor and replace the default code by the code below.
Remark: the first step was the result of using option "Enter Data". If you want to adjust data, you can use the gear button at the right from "Source" in the "Applied Steps" pane at the right hand side of the query window.
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("fc5LCoAwDATQu2RdMN+qcwf3Qun9r2GhGwNWyGLgkUxaI5FNx7DsVIgVzmAe8aJepmrWyJp2BSoj3t+7gqhJ7a0K87UaWFJvUp+9S41zfTngP19V2DEv9wc=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Date = _t, Time = _t, Status = _t]), Typed = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Time", type time}, {"Status", type text}}), AddedDateTime = Table.AddColumn(Typed, "DateTime", each [Date] & [Time], type datetime), Grouped1 = Table.Group(AddedDateTime, {"Status"}, {{"First", each List.Min([DateTime]), type datetime}, {"Last", each List.Max([DateTime]), type datetime}}, GroupKind.Local), AddedFirstDate = Table.AddColumn(Grouped1, "First Date", each DateTime.Date([First]), type date), AddedLastDate = Table.AddColumn(AddedFirstDate, "Last Date", each DateTime.Date([Last]), type date), #"Added Custom" = Table.AddColumn(AddedLastDate, "Date", each List.Dates([First Date],Duration.Days([Last Date]-[First Date])+1,#duration(1,0,0,0)), type {date}), #"Expanded Date" = Table.ExpandListColumn(#"Added Custom", "Date"), AddedStart = Table.AddColumn(#"Expanded Date", "Start", each if [Date] = [First Date] then [First] else [Date] & #time(0,0,0), type datetime), AddedEnd = Table.AddColumn(AddedStart, "End", each if [Date] = [Last Date] then [Last] else [Date] & #time(23,59,59.9999999), type datetime), AddedDuration = Table.AddColumn(AddedEnd, "Duration", each [End] - [Start], type duration), SelectedColumns = Table.SelectColumns(AddedDuration,{"Status", "Date", "Duration"}) in SelectedColumnsThe result is a table with 1 row per status/date. This will allow you to filter on status and/or dates in your visualizations.
Also the total durations - these are decimal values in the data model - need to be calculated in your visuals - or with DAX - as these depend on filter context.
I don't know if the (total) durations can be formatted as (h):mm:ss: that would require some DAX beyond my knowledge.
My advice would be to raise a new topic, specifically for "Totalling decimal values in DAX and have the results displayed as {h}:mm:ss". (Please use similar text as the topic title. "Time status" won't win the best topic title award).
Hi Anonymous
Using your Sample Data
Here are the steps
Step#1: RANK by time
Add a calculated column which will RANK based on TIME column
RANK = RANKX ( TableName, TableName[Time],, asc, DENSE )
Step 2: Identify Starting and End Points for "X"
Using this calculated Column
Previous/Next Status Is X = IF ( TableName[Status] = "X" && CALCULATE ( VALUES ( TableName[Status] ), FILTER ( ALL ( TableName ), TableName[RANK] = EARLIER ( TableName[RANK] ) - 1 ) ) <> "X", "Starting Point", IF ( TableName[Status] = "X" && CALCULATE ( VALUES ( TableName[Status] ), FILTER ( ALL ( TableName ), TableName[RANK] = EARLIER ( TableName[RANK] ) + 1 ) ) <> "X", "End Point" ) )Step# 3: Compute the Time Difference
Diff = IF ( TableName[Previous/Next Status Is X] = "End Point", DATEDIFF ( MAXX ( FILTER ( TableName, TableName[RANK] < EARLIER ( TableName[RANK] ) && TableName[Previous/Next Status Is X] = "Starting Point" ), TableName[Time] ), TableName[Time], SECOND ) )

This can be done in Power Query, using Group By and adjust the generated code by adding parameter GroupKind.Local, which will group the data by consecutive values.
let Source = Data, AddedDateTime = Table.AddColumn(Source, "DateTime", each [Date] & [Time], type datetime), Grouped1 = Table.Group(AddedDateTime, {"Status"}, {{"First", each List.Min([DateTime]), type datetime}, {"Last", each List.Max([DateTime]), type datetime}}, GroupKind.Local), Filtered = Table.SelectRows(Grouped1, each ([Status] = "X")), AddedDuration = Table.AddColumn(Filtered, "Duration", each [Last] - [First], type duration), Grouped2 = Table.Group(AddedDuration, {"Status"}, {{"TotalDuration", each List.Sum([Duration]), type duration}}) in Grouped2- AnonymousNot applicable
Hi MarcelBeug,
Thanks for your quick response, but if possible i'd like to achieve my outcome through a DAX formula not through Power Query.

Another thing is that I want to create 2 different functions for 2 seperate "Status" values. In my real dataset there are more than 2 "Status" values. That is why it would be convenient if it would be possible through a measure for example, since that would be dynamic aswell. I also need to be able to filter on "Date" in the future.

Hi MarcelBeug,
Since I was/am a complete stranger to Power Query I was a bit reticent about using it. Although I decided to try to use your code provided, it looks like it gets really close to what I want to achieve. Except it is returning the following error:
Expression.Error: We cannot apply operator - to types Text and Text.
Details:
Operator=-
Left=1899-10-1202:42:34
Right=1899-10-1202:41:21Another question I had was, in this approach is it also possible to keep the function to filter on a single day or date ? Or does this just return the totalduration for the entire file dataset ? Since I'd like to keep the filter option.
Best regards,
L.Meijdam

The date and time column must be in date and time format respectively, before using my code.
In that case, the concatenation of date and time will give a datetime field.
In your case it's just text.
The solution returns the duration for consecutive values, as requested, not per date.
If you want to filter by date, then the solution must be completely revised.
E.g. split at midnights, or will there also be additional requirements to limit the results to working hours and exclude weekends and holidays?
