expression for summation of previous 3 months columns for selected month
HI Sir,
I am developing Purchase analysis report in that I want to write expression for Consumption qty for last 3 months sum from the selected
month. for that column i have data for 12 months in terms of columns in a table MVER from SAP database. it includes 12 columns for 12 months how to write the expression for previous 3 months qty from selected month.
Ex : I have selected Aug month then I want summation of qty for May , June , July data from that table columns
It's working but when I select Jan then it will gove me GSV00 for latest year instead of that i want GSV12 for previous year. So how I will write expression for that.
