Hi @kikobi23 

Accroading the picture you have provided, do you want to calculate the value of the min id of each account?

e.g the min id of the accout 1 is 100, the min id of the account 2 is 130?

if you want to implement this, you can create a blank query and input the following code to advanced editor.

Sample data 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTI0MACRRqZKsTpQEUOwiDmSiJEBVCVIxAjENgaLmBkhREwgagwRIqYgESMTE6XYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Account = _t, ID = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Account", Int64.Type}, {"ID", Int64.Type}, {"Value", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Account"}, {{"MinID", each List.Min([ID]), type nullable number}, {"Data", each _, type table [Account=nullable number, ID=nullable number, Value=nullable number]}}),
    #"Expanded Data" = Table.ExpandTableColumn(#"Grouped Rows", "Data", {"ID", "Value"}, {"ID", "Value"}),
    #"Added Custom" = Table.AddColumn(#"Expanded Data", "RelatedValue", each List.Min(Table.SelectRows(#"Expanded Data",(x)=>x[Account]=[Account] and x[ID]=[MinID])[Value])),
    #"Reordered Columns" = Table.ReorderColumns(#"Added Custom",{"Account", "ID", "Value", "MinID", "RelatedValue"})
in
    #"Reordered Columns"

Output

If the solution above cannot meet your requirment, can you provide some sample data and the output you want? 

Best Regards!
