In Transaction Locking, once you lock a module, you will not be able to modify the transactions created before the lock date. However, you can still create transactions on the date that is specified as the lock date and modify them.
If you do not want transactions to be created on the date specified as the lock date, set the next date from the intended date as the lock date. For example, if you want to lock transactions created until March 31st, set the lock date as April 1st.
