Display First and Last date based on two week index

I currently have an index column on my Date table that counts the amount of pay periods passed since the first of the year. Each pay period is two weeks. So from 1/1/2020 to 1/14/2020 the payroll ind...

    Hi Anonymous ,

     

    Please try to use the what-if parameter. You can interact with the variable as a slicer, and visualize and quantify different key values in your reports.

    Here's my solution.

    First, I created the Payroll Index from Jan20 on my own way.

     

    Then, create a what-if parameter on the Modeling tab.

    Set your own parameters according to your needs, here my maximum value is set to 26.

    You can get a slider and a calculated table.

    Create a relationship between two tables, then you can filter through the slider.

     

    Now you can create a measure to get the text "1/1/2020 - 1/14/2020" to be displayed when the slider is selected to 0.

     

     

    Measure = MIN('Calendar'[Date])&"-"&MAX('Calendar'[Date])

     

     

    Reference: Use what-if parameters to visualize variables - Power BI | Microsoft Docs

    You can check more details from my attachment.

     

     

     

    Best Regards,

    Stephen Tao

Hi,

Try Group by on payrol index column and create aggreagations as minimum and maximum of date. Be carefoul that if in each year first period number is equal 0 then you should add custom column with the year number and group on that column as well.

 

Hope this will help you to create your own solution.

Not sure how to go about creating groups within a date table. These are my only options. 

 

Note: The index starts on 1/1/2020 so anything before that will have a negative value. It accumulates year to year so at the end of the year it doesn't reset to 0.

    Hi,

     

    Here's example how it can be done based on solution from this  post

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ZdLLDcQgEATRXDjb0nxggFgs55+GF/uyQ13fqVrq6yomYqfoKVGOIuU+/qiTBmmCVEhKMpL/SDNVUiMFqZMGaYJs1VsmJRnJSZXUSEFa9Z5pkCbIhaQbLSUZaQ2qmSqpkYLUSYM0Qe+ZWiYlGclJldRIQVr1kWmQJug900ZKMpKTVn3P1EhB6qSxkX+f2Mg+uh8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, #"Payroll index from Jan2020" = _t]),
    Custom1 = List.Buffer(List.Zip({Source[Date],Source[#"Payroll index from Jan2020"]})),
    Custom2 = Source,
    #"Added Custom" = Table.AddColumn(Custom2, "DateMin", each List.Min(List.Transform(List.Select(Custom1, (x)=>x{1}=[#"Payroll index from Jan2020"]), each _{0}))),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "DateMax", each List.Max(List.Transform(List.Select(Custom1, (x)=>x{1}=[#"Payroll index from Jan2020"]), each _{0})))
in
    #"Added Custom1"

     

    Second solution using grouping function

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ZdLLDcQgEATRXDjb0nxggFgs55+GF/uyQ13fqVrq6yomYqfoKVGOIuU+/qiTBmmCVEhKMpL/SDNVUiMFqZMGaYJs1VsmJRnJSZXUSEFa9Z5pkCbIhaQbLSUZaQ2qmSqpkYLUSYM0Qe+ZWiYlGclJldRIQVr1kWmQJug900ZKMpKTVn3P1EhB6qSxkX+f2Mg+uh8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, #"Payroll index from Jan2020" = _t]),
    #"Grouped Rows" = Table.Group(Source, {"Payroll index from Jan2020"}, {{"DateMin", each List.Min([Date]), type nullable text}, {"DateMax", each List.Max([Date]), type nullable text}}),
    #"Merged Queries" = Table.NestedJoin(Source, {"Payroll index from Jan2020"}, #"Grouped Rows", {"Payroll index from Jan2020"}, "Grouped Rows", JoinKind.LeftOuter),
    #"Expanded Grouped Rows" = Table.ExpandTableColumn(#"Merged Queries", "Grouped Rows", {"DateMin", "DateMax"}, {"DateMin", "DateMax"})
in
    #"Expanded Grouped Rows"

    Hope this will help.

      This is very close. But how do I make the source my Date table rather than just the sample json above?
