Show continuous date and reflect '0' for missing data

Hi, Anonymous 

Based on your description, I created data to reproduce your scenario, The pbix file is attached in the end.

Table:

You may create a new query and paste the following codes in 'Advanced Editor'.

let
    Source = let mindate=List.Min(Table[Delivered Date]),maxdate=List.Max(Table[Delivered Date]) in
List.Dates(
    mindate,
    Duration.Days( maxdate-mindate)+1,
    #duration(1,0,0,0)
),
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Renamed Columns" = Table.RenameColumns(#"Converted to Table",{{"Column1", "Delivered Date"}}),
    #"Added Custom" = Table.AddColumn(#"Renamed Columns", "Cust", each Table.Distinct(
    Table.FromList( Table[Cust No],Splitter.SplitByNothing(),null,null,ExtraValues.Error )
)),
    #"Expanded Cust" = Table.ExpandTableColumn(#"Added Custom", "Cust", {"Column1"}, {"Cust.Column1"}),
    #"Added Custom1" = Table.AddColumn(#"Expanded Cust", "Custom", each let 
date = [Delivered Date],cust=[Cust.Column1],
tab = Table.SelectRows(
    Table,
    each [Delivered Date]=date and 
    [Cust No]=cust
)[Doc No]
in 
tab
),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom1", "Custom"),
    #"Added Custom2" = Table.AddColumn(#"Expanded Custom", "Custom.1", each let 
date = [Delivered Date],cust=[Cust.Column1],
c=[Custom],
val = List.Sum( Table.SelectRows(
    Table,
    each [Delivered Date]=date and 
    [Cust No]=cust and 
    [Doc No]=c
)[Vol]
)
in 
if val=null 
then 0
else val 
),
    #"Renamed Columns1" = Table.RenameColumns(#"Added Custom2",{{"Cust.Column1", "Cust No."}, {"Custom", "Doc No."}, {"Custom.1", "Vol"}})
in
    #"Renamed Columns1"

Result:

Best Regards
