Formula Import and export inventory according to expiration date and age of inventory

Dear all

I have an import and export table of raw materials. I need to install the formula from columns I to Q. I want to calculate product inventory by date (first in, first out)
for example, product A has the beginning number of the period on November 30 as 5, the input is 150 (in which December 31, 2022 is 50 and January 1, 2023 is 100, I am applying import first before export). Before, 30 should be exported, including 5(November 30), 25(December 31), so the final number of product A is 125 kg, including 25kg(December 31, 2022) and 100 kg(January 1, 2023). I want the remaining number of product A according to the warehouse date to calculate the age of the inventory

THanks in advance
