Node calculation Financial statement version FSV

[JAS3311]

Hello all, I would like to do some calculations of nodes in my FSV in our starter system for Public cloud V2402. 
I found applications Define Financial Statement Nodes: Summands and Define Financial Statement Nodes: Node Calculation in CBC for my starter system. 
I don't understand the process of doing the calculation operations (see the picture). I create a summand ID in the app Define Financial Statement Nodes: Summands for my existing node that I created in my FSV in the Manage financial statement versions app. 
I then add this new summand ID in some calculation on the Define Financial Statement Nodes: Node Calculation app, I save it, and when I download a PDF version of my balance sheet from the app Balance Sheet/Income statement there is no change. 

Is it calculation of nodes shown in the picture really functioning? Like node Y001 - Y002 + Y003. Is there anyone who knows the process? 

Thank you!

Thank you

Hi Peter,

Yes, the calculation is really functioning. The customizing below is valid only for Czechia Financial Statement DRC report. There you can define the formulas based on the lined in the FS are calculated. Of course there is further customizing where you are able to link between node (e.g. Y001) and node in the FSV.
