Since some items have huge amounts of customer demand history, 
in order to speed up the opening of the item planning detail page we only present a slice of the top 80% of customer demand for the item in the history table.

At the bottom right corner of the history table there are four view options:

• 
Standard: This is the current view when first viewing the item
• Extended: Shows the all top 80% of customers as a horizontal scroll.
• All Else: Shows the customers in all else
• Full: Shows everything.
