how to rank a customer within several categories in the script reading a qvd file?
I have a qvd with customers transactions gruped by month by type of transactions (5 differente types).
I want to rank each customer by each month by each type of transaction in the script since I need to create a QVD that will serve to other applications that will use this information.
Actually I am doing it in a chart and I creeated a macro to export the result to a QVD file , but is manual and time consuming
