Compare 2 Rows in Power BI and Delete Matched Rows

tejapowerbi · Dec 1, 2018

Please see below scenarios and provide your suggestions,
My data source is in Oracle to power bi and as per my requirements I need to compare order no rows, if order number has .1 then I need to find order number without .1 and delete both rows. Does any one has any suggestion?

Order No	Match	Result
123	Yes	Delete
123.1	Yes	Delete
555	No	Keep it
444	Yes	Delete
444.1	Yes	Delete

How about you replace .1 with nothing in the order number column, then group by order number and count the number of rows. Anything with 2 has to be deleted. Join this back on the version of the order number with the .1 removed and do a left anti-join.

This is what Matt had in mind

Code:

let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Order No", type text}}),
#"Replaced Value" = Table.ReplaceValue(#"Changed Type",".1","",Replacer.ReplaceText,{"Order No"}),
Grouped = Table.Group(#"Replaced Value", {"Order No"}, {{"Count", each Table.RowCount(_), type number}}),
#"Merged Queries" = Table.NestedJoin(#"Replaced Value",{"Order No"},Grouped ,{"Order No"},"Grouped ",JoinKind.LeftOuter),
#"Expanded Table1" = Table.ExpandTableColumn(#"Merged Queries", "Grouped ", {"Count"}, {"Count"}),
#"Filtered Rows" = Table.SelectRows(#"Expanded Table1", each ([Count] = 1)),
#"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Count"})
in #"Removed Columns"
