How System will suggest automatically Min-Max at item level based on Planning policy Profiles

Dear Experts,

Anyone can guide us on how the system is providing the Minimum and Maximum quantities at the item level based on the Min - Max planning policy.

The below are the parameters i have given:

Item Level before running the "calculate Min-Max Planning Policy Parameters"

Minimum= 8
Maximum = 10

This Item having Inventory Transactions

17 - Dec - Account receipt = 50

17- Dec - Account issue = 32

Item Level after running the "calculate Min-Max Planning Policy Parameters"

Minimum= 7

Maximum = 13

Min-Max Policy profile:

Default safety stock days of cover = 10

History data in days = 50

Safety stock calculation Method = "Days of cover"

Maximum quantity calculation Method = Days of cover
