I have three reports for testing/commenting on that look at the frequency that products are being sold:
(new) Product Frequent Seller Report - lists frequent sellers over the last N months
(new) Product Infrequent Seller Report - lists infrequent sellers over the last N months
(modified) Stocktake Export Report - corrected a bug and modified with more extensive selection conditions including the ability to omit infrequent sellers

All these are for 1.9 and later.
The frequent/infrequent sellers reports will work for practices that do not use stock control - because they look at sales not stock movements.

These reports are designed to make it easier for logistics staff to separate the fast moving products from the slow moving ones. The enhanced Stocktake Export report should go into 2.0, the other two will either go into the Resource Library or into 2.0 if people feel that these are needed to run an efficient practice.

I would appreciate any feedback.
