Product IDs

Hi everyone,

I am new to Power BI and I have a table with 4 columns, each containing product IDs. How can I extract all unique product IDs from these columns into one list?


Column 1 (Product IDs) Column 2 (Product IDs) Column 3 (Product IDs) Column 4 (Product IDs)
P001 P010 P020 P030
P002 P011 P021 P031
P003 P012 P022 P032
P004 P013 P023 P033

pls try this

    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("NY2xDQAwCMN+Ye4ASQ/pjvj/jVakTFZkS8m04x62HsIbEOhWqy1kFUFgjKWsIgjE2N37H0AtaVUX", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t]),
    Custom1 = List.Union( Table.ToColumns( Source))
in
