Hello dear PBI Community,
I'm struggling with the following transformation..
I have two Tables, The one on top contains the Values I'm trying to get onto the second Table ( column1, Group 0, Group 1 ), this table doesn't get updated.
For each row in the second Table below, for the "Group 0", the values need to be compared to the "Group" &"Number 0" column ( Yellow Table ), and replace it with its corresponding numerical value. Same for "Group 1" / "Number 1", to be at the end able to see the same end result table
What is the best optimal way to achieve this transformation, knowing that my ( Column1, Group 0, Group 1 ) Table, is being updated with new rows on a weekly basis.
Thank you all for the help

Hi, @Vrykolakas ;
Try it.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WKkktLsnMS1fSUXICYkelWB1kMWcgRhMCq0QVcsQi5gLGmOqw2eCsFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, #"Group 0" = _t, #"Group 1" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Group 0", type text}, {"Group 1", type text}}),
Custom1 = let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WKkktLsnMS1fSUXICYkelWB1kMWcgRhMCq0QVcsQi5gLGmOqw2eCsFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, #"Group 0" = _t, #"Group 1" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Group 0", type text}, {"Group 1", type text}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each {List.Zip({#"Table1"[Group],#"Table1"[Number 0]}),List.Zip({#"Table1"[Group],#"Table1"[Number 1]})}
),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each List.ReplaceMatchingItems({[Group 0]},[Custom]{0}){0}
),
#"Added Custom2" = Table.AddColumn(#"Added Custom1", "Custom.2", each List.ReplaceMatchingItems({[Group 1]},[Custom]{1}){0}
)
in
#"Added Custom2",
#"Removed Columns" = Table.RemoveColumns(Custom1,{"Group 0", "Group 1", "Custom"})
in
#"Removed Columns"
