Create an expense paid by company for $100
Create the expense report > Submit to manager > Approve > Post journal entries
Go to Expenses > Expense reports, expense sheet payment status is 'paid'
Add a bank statement line for the expense and set amount to -$100
Match the bank statement with the expense payment

Issue:
Go to Expenses > Expense reports, expense sheet payment status is 'In
payment'

This occurs because in account_accountant the invoice in payment state
is 'in payment' but in expense the flow is already over
