Soft Close - control data input access while reconciling
Soft Close is a way to lock down your previous month's data from being written to, including by yourself, while the month is being reconciled. Every month, if you choose, as a part of your reconciliation checklist, one of the first things to do is to go to GL>Tasks and the "Open/Close Posting Period" task and put a check mark in the current period.
This way the data stays in tack while you are doing the necessary reconciling. Once all tie outs are complete, you have to manually open the period you are reconciling to make adjustments and entries. At this time you can also check the new file to see if there have been any entries that have been made and could not be posted to the month while you were reconciling. This way YOU are in control of your data.
When all adjustments are made and you have completed your monthly financial statements, you must do the "Close Current Period" task in GL to close that month permanently.
