hi,
our implementation, includes a parameter summary level: legacy mode (detailed incl balance), group by account (my example), summary accounts.
this is not not in the core yet, there are significant changes, including tree-level implementation and java class customization. Need interest, make design proposal idempiere way, then implementation.
the benefit against fin. report, simple run w/o any setup as is.
example: account level print format basic
example: account level print format group by L3
example: by account, the solution using script column for monthly calculation
