Number of Days Value to Rows

[fleming507]

 I have a dataset that I need to maniuplate for year end reporting, but the data from source is not entirely suitable. For each service there is a Scheduled Start Date and Numbder of days scheduled. What I'm trying to do is join it on to a calendar table (or something else) so that I have a row for each day scheduled (excluding weekends)

eg,

ServiceName    ScheduledStartDate   NumberOfDays

InstallApp         19/07/2018                5.0

to become...

ServiceName   ScheduledDate

InstallApp        19/07/18

InstallApp        20/07/18

InstallApp        23/07/18

InstallApp        24/07/18

InstallApp        25/07/18

I have a good idea how I would do this in SQL, but im trying to avoid using a database layer in between

Thanks

You can also achieve this by power query, here is link to a post which describe how this can be done?

I thought I replied to this, seems to have disappeared.

This solution works in most cases but where service may be 0.5 or 1 even 2 days it seems to add an extra day on the end.

Hi @fleming507

Try this calculated table. Assuming your table name is Table1

Table =
VAR Temp1 =
    GENERATE (
        Table1,
        VAR mydays =
            CALCULATE (
                VALUES ( Table1[ NumberOfDays] ),
                Table1[ServiceName] = EARLIER ( Table1[ServiceName] )
            )
        VAR adddays =
            (
                INT ( mydays / 7 )
                    + 1
            )
                * 2
        RETURN
            GENERATESERIES ( 1, mydays + adddays )
    )
VAR temp2 =
    ADDCOLUMNS (
        ADDCOLUMNS ( Temp1, "Scheduled Dates", [ScheduledStartDate ] + [Value] - 1 ),
        "WeekDay", WEEKDAY ( [Scheduled Dates], 2 )
    )
VAR temp3 =
    FILTER ( temp2, [WeekDay] < 6 )
VAR temp4 =
    ADDCOLUMNS (
        temp3,
        "RANK", RANKX (
            FILTER ( temp3, [ServiceName] = EARLIER ( [ServiceName] ) ),
            [Scheduled Dates],
            ,
            ASC,
            DENSE
        )
    )
VAR temp5 =
    FILTER ( temp4, [RANK] <= [ NumberOfDays] )
RETURN
    SUMMARIZE ( temp5, [ServiceName], [Scheduled Dates] )
