create list of dates with same values on dax

[eliasayy]

let
    Source = Table.Combine({
    Table.FromRows(
        {{
List.Dates( #date(2022,8, 1),  Number.From(DateTime.Date(DateTime.LocalNow())- #date(2022, 7, 31)) , #duration(1, 0, 0, 0)), 
Splitter.SplitByNothing(), {"Date"}, null, ExtraValues.Error,"Investor A",-10000,0.10}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    ),
 Table.FromRows(
        {{"8/1/2022","Investor B",-5000,0.05}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    ),
     Table.FromRows(
        {{"8/1/2022","Investor C",-15000,0.15}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    ),
 Table.FromRows(
        {{"8/1/2022","Investor D",-10000,0.10}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    ),
     Table.FromRows(
        {{"9/1/2022","Investor E",-20000,0.2}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    )
}),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Investment Company", type text}, {"Initial Value", Currency.Type}, {"Percentage", Percentage.Type}})
in
    #"Changed Type"

i tried to make a code that lists date and i want the same value so for example i nvestor A to always have 10,000 on initial value, 0.1 on percentage

because i want to createa  relationship between table and date table

Hi @eliasayy ,

According to your M code, I think first part for investor A will return 8 values, however there are only four keys in your table.

 {{
List.Dates( #date(2022,8, 1),  Number.From(DateTime.Date(DateTime.LocalNow())- #date(2022, 7, 31)) , #duration(1, 0, 0, 0)), 
Splitter.SplitByNothing(), {"Date"}, null, ExtraValues.Error,"Investor A",-10000,0.10}}

Here I suggest you to try this M code to achieve your goal.

let
    Source = Table.Combine({
    Table.FromRows(
        {{
List.Dates( #date(2022,8, 1),  Number.From(DateTime.Date(DateTime.LocalNow())- #date(2022, 7, 31)) , #duration(1, 0, 0, 0)), 
"Investor A",-10000,0.10}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    )
}),
    #"Expanded Date" = Table.ExpandListColumn(Source, "Date"),
    #"Combine" =
    Table.Combine({
#"Expanded Date",
        Table.FromRows(
        {{"8/1/2022","Investor B",-5000,0.05}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    ),
     Table.FromRows(
        {{"8/1/2022","Investor C",-15000,0.15}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    ),
 Table.FromRows(
        {{"8/1/2022","Investor D",-10000,0.10}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    ),
     Table.FromRows(
        {{"9/1/2022","Investor E",-20000,0.2}},
        {"Date", "Investment Company","Initial Value","Percentage"}
    )
}),
    #"Changed Type" = Table.TransformColumnTypes(Combine,{{"Date", type date}, {"Investment Company", type text}, {"Initial Value", Int64.Type}, {"Percentage", Percentage.Type}})
in
    #"Changed Type"

 Result is as below.
