Extending Financial Year - NAV 5

We have the requirement to extend our current financial year by 2 months. Can I just add the new periods?
The next financial year has not been added yet.

It’s the first time I see such requirement, out of curiosity tried to do this, turned out the fields are editable manually [:)]

Supposing Period length is 1M in your setup:

Notice that there is one extra month after the last month of defined period, having a checkmark in New Fiscal Year column. Clear this checkmark, add 1 month (given the needed extension is 2M) + one extra, and in that extra one check the NFY field.

The batchjob CreateFiscalYear doesn’t do anything else than populate AccountingPeriods for you, if Period=1M it’s easy, but batchob can handle also weird Period lengths (and count), where date calculations are more complicated.
