Creating counters in more than one instance

OsmanEmi , Create a new column like

countx(filter(Table, [Restaurant ID] = earlier([Restaurant ID]) && [Delivery Date] >=earlier([Delivery Date]) ),[Restaurant ID])

Hi OsmanEmi 

 amitchandak 's reply use countx funtion to achieve your goal, and you can try my way to use rankx function to build a calculated column or use M query to build a column in Power Query Editor.

Calculated column:

C.Counter = RANKX(FILTER('Table','Table'[Restaurant ID]=EARLIER('Table'[Restaurant ID])),'Table'[Delivery Date],,DESC)

M query:

You need sort ID column by asc and sort Date column by Desc, group by ID column (Operation = ALLROWS)

Add a custom column , reomve other columns and expand custom column.

Custom = Table.AddIndexColumn([AllROWS],"Rank",1,1)

Mquery in Advanced Editor.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTIy1zc01DcyMDJQitWJVjLCFDLGFAJrNMMUMsU0yxTTLFNMjSYIoVgA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Restaurant ID     " = _t, #"   Delivery Date                    " = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Restaurant ID     ", Int64.Type}, {"   Delivery Date                    ", type text}}),
    #"Renamed Columns" = Table.RenameColumns(#"Changed Type",{{"   Delivery Date                    ", "Delivery Date"}, {"Restaurant ID     ", "Restaurant ID"}}),
    #"Sorted Rows" = Table.Sort(#"Renamed Columns",{{"Restaurant ID", Order.Ascending}, {"Delivery Date", Order.Descending}}),
    #"Grouped Rows" = Table.Group(#"Sorted Rows", {"Restaurant ID"}, {{"AllROWS", each _, type table [Restaurant ID=nullable number, Delivery Date=nullable text]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each Table.AddIndexColumn([AllROWS],"Rank",1,1)),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Restaurant ID", "AllROWS"}),
    #"Expanded Custom" = Table.ExpandTableColumn(#"Removed Columns", "Custom", {"Restaurant ID", "Delivery Date", "Rank"}, {"Custom.Restaurant ID", "Custom.Delivery Date", "Custom.Rank"}),
    #"Renamed Columns1" = Table.RenameColumns(#"Expanded Custom",{{"Custom.Rank", "Counter"}}),
    #"Sorted Rows1" = Table.Sort(#"Renamed Columns1",{{"Custom.Delivery Date", Order.Descending}}),
    #"Renamed Columns2" = Table.RenameColumns(#"Sorted Rows1",{{"Counter", "MQ.Counter"}, {"Custom.Restaurant ID", "Restaurant ID"}, {"Custom.Delivery Date", "Delivery Date"}})
in
    #"Renamed Columns2"

Result is as below.
