I have seen older posts on here and other forums with the similar code to the one below and cannot figure out where a portion of it comes from.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlHSUXJ0BBJOiUXJqTn5eYlAdlhiTmpecmaiUqxOtJIpTAVcFFkxSIUZTIVvYkpRZgqQEZSfC5Eyh0mBReAqQFIW2GxGkrfEMBXVVkMDkAInfE43NIQpwel2QyOQEmesjjc0hslhut7QBCaHbDtCqymaViRbYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [ID = _t, Company = _t, Origin = _t, Destiny = _t]),
Group = Table.Group(Source, {"Origin"}, {{"Count", each List.Count(List.Distinct(_[Destiny])), type number}, {"Destinations", each Table.FromRows({List.Distinct(_[Destiny])}), type table}}),
AllColumnNames = Table.ColumnNames(Table.Combine(Group[Destinations])),
#"Expanded Destinations" = Table.ExpandTableColumn(Group, "Destinations", AllColumnNames, AllColumnNames)
in
#"Expanded Destinations"
What I cannot figure out is where the "i45WMlHSUXJ0BBJOiUXJqTn5eYlAdlhiTmpecmaiUqxOtJIpTAVcFFkxSIUZTIVvYkpRZgqQEZSfC5Eyh0mBReAqQFIW2GxGkrfEMBXVVkMDkAInfE43NIQpwel2QyOQEmesjjc0hslhut7QBCaHbDtCqymaViRbYwE=" part comes from. I know it can be from if data is manually entered but I have also seen where it can link to other data sources. I have a use case where I have calculated columns in dax but need to manipulate those calculated columns in Power Query. Is there a place where this string is stored for each data source? I understand everything after the source line but this has me stumped.
