Accounting for inventory(Material Inventory Account)

Sir in the material cost account
We usually
debit
opening balance
Purchases
Return to stores

Credit
Issues to production
Returns to suppliers
Production overheads
Statement of profit and loss

So does this mean that if a business makes a profit in the income statement
This will be debited in the material cost account?

And if the business makes a loss it would be credit in the material cost account?
