Hi,
In the example below I want to filter those Customers that have a Discovery and Project Work. I want to filter out those Customers that do not have a Discovery. So for the example below I would like to remove rows 4 and 5. Is this possible, if so can you please tell me how? I have tried numerous approaches but none succesfully.
Many thanks
Number | Customer | Project | Project Type |
1 | A | 1111 | Discovery |
2 | A | 1112 | Project Work |
3 | A | 1113 | Project Work |
4 | B | 2222 | Project Work |
5 | C | 3333 | Project Work |
6 | D | 4444 | Discovery |
7 | D | 4441 | Project Work |
Solved! Go to Solution.
In the Query Editor (Power Query) it can be done as follows.
Steps:
Generated code, starting with the first step after your last step (which I called PreviousStep, so adjust with the name of your last step):
#"Sorted Rows" = Table.Sort(PreviousStep,{{"Customer", Order.Ascending}, {"Project Type", Order.Ascending}}), #"Added Index" = Table.AddIndexColumn(#"Sorted Rows", "Index", 0, 1), #"Added Index1" = Table.AddIndexColumn(#"Added Index", "Index.1", 1, 1), #"Merged Queries" = Table.NestedJoin(#"Added Index1",{"Index"},#"Added Index1",{"Index.1"},"Previous",JoinKind.LeftOuter), #"Expanded Previous" = Table.ExpandTableColumn(#"Merged Queries", "Previous", {"Customer"}, {"Previous.Customer"}), #"Sorted Rows1" = Table.Sort(#"Expanded Previous",{{"Index", Order.Ascending}}), #"Added Custom" = Table.AddColumn(#"Sorted Rows1", "Keep", each if [Project Type] = "Discovery" then true else (if [Customer] <> [Previous.Customer] then false else null)), #"Filled Down" = Table.FillDown(#"Added Custom",{"Keep"}), #"Filtered Rows" = Table.SelectRows(#"Filled Down", each ([Keep] = true)), #"Removed Columns1" = Table.RemoveColumns(#"Filtered Rows",{"Index", "Index.1", "Previous.Customer", "Keep"}) in #"Removed Columns1"

Thank you, took me a while to get my head round it, but that works.
