For a given SKU, you can view a comprehensive timeline of pricing and inventory updates and orders associated with the SKU. Here's how:
In the Catalog => click a SKU
On the left sidebar for a given SKU => Click the 3-vertical-dot icon at the top of the page => Select Product History
Click the "All Activity" drop-down list if you would like to select "Inventory Updates Only" or "Pricing Updates Only"
Pricing updates will be stored in the product history. There is also a graph tracking the previous 48 hours of the item price on Zentail. This graph will denote whether this product owned Amazon's buy box at a specific price and time.
Product Data Updates
Currently, changes to Title, Smart Type, Amazon Item Type, Package Weight, and Model Number are tracked as Product Data changes. Other changes, like images, description, and bullet points, are not tracked in the Product History of a SKU.
