Perhaps i did not explain myself that well.
What i means is that I want to make a budget for 2020 split in months.
In December 2019 i have an estimated closing balance (which i made in October 2019, so it is not equal to the actual closing figures for 2019 - but estimated). I want to enter that estimated end-2019 balance somewhere, so that January 2020 knows that e.g. "Other Debt" starts in 400.000 EUR, meaning if i want end-January 2020 to be 500.000, i just enter the month's transaction of 100.000, and not just the 500.000 as end-balance.
The reason for this, is that in Financial Reports i calculate the cash flow automatically, and i cannot figure out how i only show the periodic flow in January 2020 - and also how i show opening cash, which of course is caused by the same issue, that i cannot enter an opening balance.
What i tried to do was to enter figures in the same scenario, which i called "BUD20" for December 2019, but my opening balance for January 2020 still shows zero.
I may just have overlooked a simple solution, but it is completely invisible for me right now.
