Yesterday I got a query by a user of ours with the DOS system who wanted to see if he could do an analysis of magazine's supplies with his system. He also felt that there was a big difference between magazine's suppliers.
The conclusions were interesting for 18 months; we ran our DOS system has a fine system for analysising sales data. If you use POS DOS you will find it in Stock->Supply reports->Magazine
Here is the result. You tell me if you can see much difference. I do not. Click on image below for more details
I think this shows the danger of using feel rather than data. Data should always be right.
