Hello everyone,

I'm new to Odoo and need help fixing records after importing all field service, timesheet and invoice records. 

Have managed to link field service and timesheets. But can't figure out how to link them to the invoice they were billed on. It only offers to create a new invoice/sales order.

I could create new invoices, merge them with the old ones and hope that works. But it'd be super time-consuming and manual for years of records.

Going to look at the DB directly later today. If anyone could provide some advice on how to get this done it would be much appreciated.
