FAQ - ExpensiError FF0076: Could not find employee in FinancialForce
If you are running into this error when attempting to export your reports, you'll want to go to Contacts in FinancialForce and add the report creator/submitter's Expensify email address to their employee record, or create a record with that email listed.
If a record already exists then search for their email address to confirm it is not associated with multiple records.
