Hi All, I am stuck in a problem where I have a data which is today's data, there is a column named current data, I want that data to be in my workflow which is simple, now comes the tricky part where I want a new column which has a previous data, in this column I want to update data of yesterdays "current data". I have only one input file for today, I can't have 2 inputs, so this becomes difficult for me to distinguish between today and yesterday, can someone please explain the solution.
