Automatic Intercompany immediately creates the corresponding Purchase Order. However, the intercompany Sales Order is created by the scheduled Auto Multi Company process. Process details can be seen in the System Monitor.
When the created intercompany orders have been shipped an AR Invoice will be created and posted, while an AP Invoice will be created and posted when the Auto Multi Company process runs.
Furthermore, when a parent company handles centralised payments, Automatic Intercompany will automatically process and accept AP Invoices when they have been pushed to the parent company.
