Large databases that have changed names (new custnrs etc.) - how fix?
I have a problem that someone probably knows a easy way to solve. I have large excelcharts with all salesdata for the last years in detail. The problem is that we have changed customer numbers (customer segments names, some artnrs etc.) and a lot more. Can someone please advise on how to combine these in an easy way so I can use this in Qlikview?
