Why can't I depreciate assets past the end of my financial year?
To process depreciation for the next financial year, the database requires a “rollover” to the new financial year. Before the "rollover" happens, all significant data entry to July of the current year, especially stock transactions, should be complete.
You do not have to include tax adjustments and adjustments made by accountants and auditors – these can be done after rollover.
The alternative is to post an estimated depreciation journal to get you through July, which can be reversed when the system is rolled and the correct depreciation is done. It can be made very accurate by rolling over a TEST copy of the LIVE database and then performing the depreciation actions so you can have accurate data for your journal.
More information is available in the End of year rollover guide.
