Hi Naren,
The system is not accounting properly because the finance team is running the VF01 for a billing plan line that has due date for three months later or whatever out of the current fiscal period.
In this way, as the vf01 is executed in july for exame for a billing plan line that has due date in september, as september is not an open period for accounting yet, the document is created, bur as accounting fails it goes to the vfx3 log.
Please let me know if it clarifies.
Thanks
Aislan
