Deleting/Removing specific rows in Power BI Query

[Anonymous]

Hi Power BI Team,

I need your help! 

I got a column with actions like refurbisment, Load and Credit(Gutschrift). 

The action Credit shows wrong and unneeded data. I want to delete the wrong rows but How can I do this with only the PB Option delet first and last rows...
I also need the other actions. I can not just only select Credit.

 
I want everything delet in Action(Maßnahme) Credit(Gutschrift) which has not these numbers:

 
The big problem is that I only want to affect a part of a column and Query not the entire thing...

Hello @Anonymous 

to delete some rows you can use Table.SelectRows and filter them out. If you need to keep some of this deleted rows, you can use a list and add in the Table.SelectRows a List.Contains-function. Here a practical example how this could work for you

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUQosTczJLDm8pEQpVidaKQlDJBko4l5aUpycUZSZBhHCrg1NEdH68FsXCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Maßnahme = _t, IDS = _t]),
    ChangedType = Table.TransformColumnTypes(Source,{{"Maßnahme", type text}, {"IDS", type text}}),
    YourListWithNumbersToKeep = {"a","b","c"},
    SelectYourRows = Table.SelectRows
    (
        ChangedType,
        (row)=> not(row[IDS]="Gutschrift" and List.Contains(YourListWithNumbersToKeep, row[Maßnahme]))
    )

in
    SelectYourRows

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
