Creating dynamic measures to calculate duration between different timestamps

Dear all,

I have a database with logs of clients going through different stages of a process.

Each process has timestamp indicating the date when the single client has reached that stage of the process.

I want to create in DAX a dynamic measure that would allow users to choose the stages they want to calculate a lag time between. E.g.: one might be interested to investigate how many days (on average) elapse between date 1 and date 0, or between date 2 and date 0, and so on...

I tried using field parameters for start date and arrival date, in order for the user to just choose in a filter the starting point and the arrival point of the measure, which would be ideal for me. Nonetheless, it seems I can't be able to get this to work.

How would you proceed?

Thanks in advance for your kind help.

Giorgio

HI Anonymous,

I'd like to suggest you convert the table records to do complex unpivot column operation on these status and date fields:

Full query:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [SNDG = _t, #"Data 0: Inizio monitoraggio" = _t, #"1: Contatto cliente" = _t, #"Data 1: Contatto cliente" = _t, #"2: Rintraccio" = _t, #"Data 2: Rintraccio" = _t, #"3: Analisi posizione e condivisione strategia" = _t, #"Data 3: Analisi posizione e condivisione strategia" = _t, #"4: Delibera" = _t, #"Data 4: Delibera" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"SNDG", Int64.Type}, {"Data 0: Inizio monitoraggio", type text}, {"1: Contatto cliente", type text}, {"Data 1: Contatto cliente", type text}, {"2: Rintraccio", type text}, {"Data 2: Rintraccio", type text}, {"3: Analisi posizione e condivisione strategia", type text}, {"Data 3: Analisi posizione e condivisione strategia", type text}, {"4: Delibera", type text}, {"Data 4: Delibera", type text}}),
    fxTrans= (tb as table) =>
        let 
            #"Unpivoted Columns" = Table.UnpivotOtherColumns(tb, {}, "Attribute", "Value"),
            #"Added Custom" = Table.AddColumn(#"Unpivoted Columns", "Step", each Text.Combine(List.Select(Text.ToList([Attribute]), each Value.Is(Value.FromText(_), Int32.Type )))),
            #"Grouped Rows2"= Table.Group(#"Added Custom", {"Step"}, {{"Count", each Table.Transpose(Table.SelectColumns(_,{"Value"})), type table }}),
            #"ExpandTableColumn" = Table.ExpandTableColumn(#"Grouped Rows2", "Count", {"Column1", "Column2"}, {"Status", "Date"})
        in
            #"ExpandTableColumn",
    #"Grouped Rows" = Table.Group(#"Changed Type", {"SNDG", "Data 0: Inizio monitoraggio"}, {{"Content", each fxTrans(Table.RemoveColumns(_,{"SNDG", "Data 0: Inizio monitoraggio"})), type table }}),
    #"Expanded Content" = Table.ExpandTableColumn(#"Grouped Rows", "Content", {"Step", "Status", "Date"}, {"Step", "Status", "Date"})
in
    #"Expanded Content"

After these steps, you can simply use Dax expression with current group field value(SNDG) and steps as conditions. Then you can use them to find out correspond date values and calculated in DATEDIFF function.

Hi Anonymous ,

Can you please share a pbix or some dummy data that keep the raw data structure with expected results? It should help us clarify your scenario and test to coding formula.

Here is the dummy data I'm starting from.

As you can see, there are several steps of the process, and each step has a datestamp (Data 1, Data 2, Data 3, etc.)
My measure would ideally use DATEDIFF or a similar function but the starting and end datestamps should be variable or subject to user decision.

Thanks for your help!
