I cannot understand what Define Line Layouts means in SPRO.
Financial Accounting -> General Ledger Accounting -> Line Items -> Display Line Items -> Define Line Layouts
I can see that there is some Line Layout Variant (D0,D1D2...), with some Fields, but i cannot understand where this fields or Line Layout Variants are used, in what transactions i can see changes if a made some. This variant reflects line layouts when i post something (f-02, ,f-03, f-04, f-51...) or when i want to see account items or balances ???.
