Not sure what loss commission is. If it is money you would have gotten but did not, you can’t deduct that. Many businesses do not have a profit from time to time. If you have good records you need not be concerned. If you have a loss more than 2 times in 5 years you will be considered as having a hobby and can’t deduct any expenses.
EDIT. 3 times in 5 years is correct as pointed out by @Opus 17.
