NewStep=#table(Table.ColumnNames(PreviousStepName),Table.ToList(PreviousStepName,each let a=List.Count(_) in List.LastN(List.Repeat({null},a)&List.Distinct(_),a)))

Thank you for your reply, sorry, I could not make it work, would you please explain a bit more? as I am not familiar with M code. especially what does #table mean? how should I replace it?

Hi @Walter_W2022 ,

Here you can open the advanced editor:

To the left of the "=" sign are the names of the individual steps; if they contain special characters (e.g. spaces), they must be nested outside #"".

Our previous step name was #"change type", so here we replace PreviousStepName with #"change type" and you can replace this step name as required.

Finally we need to return the result of the Custom1 step, so the result after in needs to be changed to Custom1.

Result.
