Date parameter for filtering multiple tables

[pbinewb]

Hi Evereyone,

I have Dynamics NAV tables to join where some tables are imported from overseas. Because the internet connection over there is crappy i would like to dynamically filter the table (rows) based on a "From Date" parameter at the opening of the pbix file?

Ideally I would like to have a custom table with specific parameter values that are used in the filtering of other tables.

So i have a testtable like this:

let
    Source = Excel.Workbook(File.Contents("C:\Temp\BITEST.xlsx"), null, true),
    testTable_Sheet = Source{[Item="testTable",Kind="Sheet"]}[Data],
    #"Promoted Headers" = Table.PromoteHeaders(testTable_Sheet, [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"No_", Int64.Type}, {"Date", type date}, {"Description", type text}})
in
    #"Changed Type"

Which contains:

No_	Date	Description
123	29-09-17	test 123
124	03-10-17	test 124
125	05-10-17	test 125

And would like to have a Parameters Table with something like this:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcivKz3VJLElV0lEyMNQ1NNA1NFeKjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Parameter = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Parameter", type text}, {"Value", type date}})
in
    #"Changed Type"

Which contains:

Parameter	Value
FromDate	01-10-17

How can I filter the first table to only import rows where the Date > Parameter.FromDate ?

Or maybe there are better solutions.

The actual tables contain 30+ columns and 400K+ rows and only need about 10% of that in my Dashboard.

Thanks in advance.

You can also use single parameters in PowerBI, but a table works just as fine in my eyes. So assume your parameter table is called "Parameters" this code should work:

let
    Source = Excel.Workbook(File.Contents("C:\Temp\BITEST.xlsx"), null, true),
    testTable_Sheet = Source{[Item="testTable",Kind="Sheet"]}[Data],
    #"Promoted Headers" = Table.PromoteHeaders(testTable_Sheet, [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"No_", Int64.Type}, {"Date", type date}, {"Description", type text}})
    #"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([Date] >= Parameters{[Parameter="FromDate"]}[Value]))
in
    #"Filtered Rows"

Hi Imke,

Thanks for your solution.

Its works, so now i can extend the Parameters table with additional filters.

Beginning to see the advantages of PowerBI.
