    Hi Anonymous 

    If the columns you want to rename will always be the 1st and 2nd ones, you can reference the columns by their index (indexed from 0)

     

     

    #"Renamed Columns" = Table.RenameColumns(#"Promoted Headers",{{Table.ColumnNames(#"Promoted Headers"){0}, "TIME"}, {Table.ColumnNames(#"Promoted Headers"){1}, "MARKET"}, {"Column3", "SEGMENT"}, {"Column4", "SUB-SEGMENT"}, {"Column5", "UPC"}, {"Column6", "DESCRIPTION"}, {"Column7", "SIZE"}, {"Column8", "FLAVOR"}, {"Column9", "BRAND"}})

    No these 2 lines are not needed

     

    DynamicNameHeader= Table.ColumnNames(#"Promoted Headers"){0},
DynmaicNameHeader.1= Table.ColumnNames(#"Promoted Headers"){1},

     

    All they do is assign the names of the first 2 columns to variables.  But these variables are not used in the subsequent  Table.RenameColumns

     

    #"Renamed Columns" = Table.RenameColumns(#"Promoted Headers",{{Table.ColumnNames(#"Promoted Headers"){0}, "TIME"}, {Table.ColumnNames(#"Promoted Headers"){1}, "MARKET"}, {"Column3", "SEGMENT"}, {"Column4", "SUB-SEGMENT"}, {"Column5", "UPC"}, {"Column6", "DESCRIPTION"}, {"Column7", "SIZE"}, {"Column8", "FLAVOR"}, {"Column9", "BRAND"}})

PhilipTreacy I found a YouTube video that said to add two lines after the #Promoted Headers:

#"Promoted Headers" = Table.PromoteHeaders(#"Removed Top Rows", [PromoteAllScalars=true]),
DynamicNameHeader= Table.ColumnNames(#"Promoted Headers"){0},
DynmaicNameHeader.1= Table.ColumnNames(#"Promoted Headers"){1},
#"Renamed Columns" = Table.RenameColumns(#"Promoted Headers",{{Table.ColumnNames(#"Promoted Headers"){0}, "TIME"}, {Table.ColumnNames(#"Promoted Headers"){1}, "MARKET"}, {"Column3", "SEGMENT"}, {"Column4", "SUB-SEGMENT"}, {"Column5", "UPC"}, {"Column6", "DESCRIPTION"}, {"Column7", "SIZE"}, {"Column8", "FLAVOR"}, {"Column9", "BRAND"}})

 

Are the 'DynamicNameHeader' Lines not needed?

 

Thanks
