stock balance adjustment without accounting effect

[zamir77]

I have a stock that was not charged out back in 2018, I need to charge out the stock in 2023. The Quantity carried forward was 2000 kg in the amount of RM1,300. The first step was taken by using MR21 to change the price from RM1,300 to RM0.00. The T-code used to post the stock out was done in MIGO using code Z01. However, it has reflected the income statement under "loss on revaluation of stock" due to a price reduction from RM1,300 to RM0.00. Previously, the transaction used GL code to record the cost of sales without using the MM module. Please assist me with how we can deduct the quantity in the stock card (MM module) as zero balance without hitting the expenses, or else we have a double charge to the account, which was taken into account in 2018 using the GL code. This is urgent for me to clean up the balance previously done by other staff.
