I have to refer to a previous date value. I have an expression which gives me Maxdate value month wise. I need to calculate the previous day value in the next column. That is, I need something like : Below( Previous calculated column). But it is not working. Any help is appreciated. I am using a straright table.
Thanks a lot Anatoly. I was struggling with this AGGR, RANK and IF ordering. Now i would look into it carefully and improve my knowledge base for sure.
