New column - If value = null, use value on previous row.
I got data from my source in a csv formated like this.
| Got this | Got this |
| 4001 | Value |
| 4002 | Value |
| Value | |
| 4003 | Value |
| Value | |
| Value | |
| Value | |
| 4004 | Value |
| Value | |
| Value | |
| Value | |
| Value | |
| Value |
In order to connect it to my other data I need it like this
| Got this | Want this | Got this |
| 4001 | 4001 | Value |
| 4002 | 4002 | Value |
| 4002 | Value | |
| 4003 | 4003 | Value |
| 4003 | Value | |
| 4003 | Value | |
| 4003 | Value | |
| 4004 | 4004 | Value |
| 4004 | Value | |
| 4004 | Value | |
| 4004 | Value | |
| 4004 | Value | |
| 4004 | Value |
How do I create the calculated(?) column in the example above?
Thanks in advance!
Just use the Fill down feature. Place the following M code in a blank query to see the steps.
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjEwMFTSUQpLzClNVYrVAQsYoQgooEsb45HGxwNqNSFTK05eLAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Got this" = _t, #"Got this.1" = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Got this", Int64.Type}}), #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each [Got this]), #"Filled Down1" = Table.FillDown(#"Added Custom",{"Custom"}), #"Reordered Columns" = Table.ReorderColumns(#"Filled Down1",{"Got this", "Custom", "Got this.1"}) in #"Reordered Columns"Please mark the question solved when done and consider giving a thumbs up if posts are helpful.
