Error Specified key is not a valid size for this algorithm

Hey Greg_Deckler , I am extracting from an SAP Database:

let
Source = SapHana.Database("mrkhana01:30015", [Query="SELECT * from ""EDW_STAGING"".""CORPORATE_SHAREPOINT_DAILY_PRODUCTION_NUMBERS"""]),
#"Removed Columns" = Table.RemoveColumns(Source,{"ORG_KEY", "MODIFIED_BY", "MODIFIED_DATE", "CREATED_BY", "CREATED_DATE", "BATCH_ID_ORIGINAL", "BATCH_ID_UPDATED", "ID"}),
#"Filtered Rows" = Table.RemoveColumns(Source,{"ORG_KEY", "MODIFIED_BY", "MODIFIED_DATE", "CREATED_BY", "CREATED_DATE", "BATCH_ID_ORIGINAL", "BATCH_ID_UPDATED", "ID"}),
#"Filtered Rows3" = Table.SelectRows(#"Filtered Rows", each ([ESTIMATE_FORECAST] = "Estimate")),
#"Renamed Columns" = Table.RenameColumns(#"Filtered Rows3",{{"DATE", "Date"}, {"MINE", "Mine"}, {"ESTIMATE_FORECAST", "Plan Version"}}),
#"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Renamed Columns", {"Date", "Mine", "Plan Version"}, "Attribute", "Value"),
#"Renamed Columns1" = Table.RenameColumns(#"Unpivoted Columns",{{"Attribute", "Metric"}}),
#"Added Custom" = Table.AddColumn(#"Renamed Columns1", "Version", each "Actuals"),

in 

#"Added Custom"

When I try to Pivot the data, the error is thrown. I would add the step in the Query Editor and it appears like this in the Advanced Editor:

#"Pivoted Column1" = Table.Pivot(#"Renamed Columns2", List.Distinct(#"Renamed Columns2"[#"Metric Code"]), "Metric Code", "Actuals", List.Sum),
