Hiya good people,
I am trying to solve, possibly a wierd problem. I have a table as below :
What I want to do is as follows :
In each of the table under the [Data] column, i want to insert a column which will populate the new column with the corresponding name under the column [Account]. E.g. In the 1st table, from the [Data] column, I would like to insert a column, filled with the account name, "JioMart"
If I simply use Table.AddColumn, I am getting an error.
Is there a way to solve this in power query?
Any help much appreciated
Solved! Go to Solution.
NewStep=Table.ReplaceValue(PreviousStepName,each [Account],"",(x,y,z)=>Table.AddColumn(x,"Account",each y),{"Data"})
@wdx223_Daniel - That worked like a charm, although I could not understand the logic fully...
E.g. how is the function getting its values for x,y & z?
the 4th parameter of Table.ReplaceValue is a function of Replacer.ReplaceText or Replacer.ReplaceValue
and, about the syntax of those function you can refer to this site.

NewStep=Table.ReplaceValue(PreviousStepName,each [Account],"",(x,y,z)=>Table.AddColumn(x,"Account",each y),{"Data"})
