Hi @dduc2310 ,

1. Whole M In Power Query:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUQooSi1OzStJTVGK1YGI+OWXKFAmiirihFUddlFnDN3OxKiLBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ProjectName = _t, #"Presented Or Not" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ProjectName", type text}, {"Presented Or Not", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"ProjectName"}, {{"Count", each _, type table [ProjectName=nullable text, Presented Or Not=nullable text]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each if Table.Contains([Count],[Presented Or Not="Presented"]) then "Presented" else "Not Presented"),
    #"Expanded Count" = Table.ExpandTableColumn(#"Added Custom", "Count", {"Presented Or Not"}, {"Presented Or Not"})
in
    #"Expanded Count"

2. try the following DAX formula:

Result = 
var _t=DISTINCT( SUMMARIZE('Table','Table'[ProjectName], 'Table'[Presented Or Not]))
return IF( COUNTX(FILTER(_t,[ProjectName]=EARLIER('Table'[ProjectName])),[Presented Or Not])=2,"Presented",[Presented Or Not])

Below is the final output:

This is better done in DAX.  Use COUNTROWS(VALUES([ProductName])) and test if it is more than 1.
