NewStep=#table(Table.ColumnNames(PreviousStepName),List.Accumulate(Table.ToRows(PreviousStepName),{{},""},(x,y)=>{x{0}&{List.RemoveLastN(y,1)&{if List.Last(y)=x{1} then null else List.Last(y)}},List.Last(y)}){0})

Thank you so much daniel. It worked as charm. 

However, I have various other columns to execute as same as above. 

As I remember the code, the code doesnt mention the column name. 

So, how Will I achieve this?

 

what is the frame of your data? and what is the rule of replacement? 

My data is like 8 columns and some rows.

Remember, what happens when we perform groupby and use some column as "SUM" aggregator while some columns to show all the rows instead of doing any aggregation?

The "All rows" aggregator repeats all the values for a specific column.

My need is to show the values of those columns only one time for each ID, not repetative.

Like in the screenshot above, You helped me in achieving each Brand name for each ID, despite having numerous model names.

I want to do the same with multiple columns. Like for 6-7 column at once.

If you have a different approach for this, feel free to enlighten me.

Thanks in Advance.
