Error:  Transaction date is before the Financial Cutoff Date

You can set up and manage the Financial Cutoff Date in (GL > Financial Cutoff Date).  

This screen provides a means of controlling the ‘Posting’ of transactions that have a financial implication.   For example, you may already have carried out Tax returns based upon a fixed period (Month, 3 months, etc).   Having completed the return you will want to prevent any further transactions within that time period.  If posting an invoice prior to this date, make sure to check with your company accountant so that they are expecting a potential change in previous numbers/reports.
