Accounting issue in Payables

Hello,

Normally we can pass manual accounting entry in xla(subledger) if user want to pass accounting entry. Event_type_code & Accounting_entry_code value as MANUAL for manual accounting entries in xla.

But i have seen few accounting entries with event_type_code & accounting_entry_code as MANUAL along with source_id_int_1 as invoice_id. It is automatically passed by create accounting program.

And also i have seen description as "Accounting Error Correction - Offsetting journal entry for the event_id xxx For invoice_id: xxx in xla_ae_headers & xla_ae_lines table:

Just i want to know when system will pass manual accounting entry for invoice.
