Zero Balance Adjustment Entries not generated for sales transaction in the item ledger

Hi , I've been facing some scenarios where most of the sales transactions are undergoing the same type of transaction and situation where the inventory is fully relieved where balances are still in the account. Some transactions would generate a zero balance adjustment in the item ledger (F4111) but some would not generate any zero balance adjustment entries in the item ledger which causes item balance/item ledger integrity issues. Is a common issue or are there any additional setups that I've missed out? Assistance on this issue would be appreciated . Thanks
