Mavenlink Line Item Locks API

Line Item Locks provide a way for you to lock time in the past so that previous time entries cannot be edited or updated and new time entries cannot be created before the selected lock date. Line Items can be locked to any Saturday in the past on a per-account basis. Keep in mind that this feature does not lock the ability to invoice approved time entries, nor does it lock the submission or approval of expenses. Also note: Line Item Locks cannot be modified or deleted. If you would like to move the lock date forward, simply create a new lock at a later date, and your account will be locked at the new date. Once your account has been locked, the lock cannot be moved earlier, or removed.
