Is there also a way to access the actual previous period, i.e. the period right before the current one?
e.g. for a monthly reporting client, when I am in the period for March, I want to access the period for February, etc.

Wait, you probably mean reports right, instead of Liquid-templates ?

If so, that is indeed not possible but it shouldn’t be because you can add an extra period which gives you the desired number, through the drag-and-drop function to add periods. Or did you wish to calculate with it in a formula?

I appologize for the lack of clarity in my previous post.
I did indeed mean to use this notation to acquire the value of an account(range) at the end of a previous period, to use in calculations in formulas in reports.

For now not possible indeed (however, this has been added as a feature request). If you want to know the status of this, be sure to ask this through our chat or support@silverfin.com

But, you should be able to have a workaround where you calculate the formula through liquid. Take the outcome of that into a result, so you can link that number into a report.
