Currently in accounting document generated for billing document am getting two line items ( one credit for G/L( say GL01) against posting key 50) and second for debit against posting key 01.( scenario for periodic billing)
Now business wants to add another line item for tax against another G/L say GL02.
I know G/L01 is added in VKOA that's why am getting that account in accounting document ( though GL02 is also added against some AAG).
Now how can I get three line items in accounting document for periodic billing , what changes do I need to do in VKOA against GL02 and or GL01.
