Nav 2016: Looking for a report that would show the least amount of sales against items within Bin Contents.

The old 80/20 rule - 20% of inventory usually accounts for 80% of sales.

Therefore 80% of inventory is slower movers.

I would like to see what our slowest moving items are and move them if they happen to be in high-efficiency picking locations.

Rule is universal and is right also.
But I dont think we have any such report in our base of Navision.
You have to customize and create your create by your developer.
