To remove financial periods, go to Step 1: Update Data in the settings for your company. Under the 'Financials' section, there is a link called 'remove periods'. Here, you can remove the prior, incomplete or future periods from your company.
Note: When removing prior periods, you will not be able to add the periods to back once they are deleted. You will need to delete and re-import the company to add these periods back at a later time.
Viewing YTD periods
You can also remove periods to see YTD results to a specific period. For example, if you remove July to December 2018, your YTD results should display as expected (to June).
At any time in the future you can then update and re-import results for these periods, when these periods are ready for analysis.
