If i have "statement of account" wizard to chose one of the "Unpaid options"  and i chose the unreconciled invoices which it will  print everything inside  Partner Ledger with the option "only show unreconciled Entries" 

and i put this domain :

if unpaid_options == 'unpaid_bills':
    domain += ['|', ('payment_state', 'in', ['not_paid']), ('payment_state', '=', 'partial')]

but it return only the payment which have invoice,

how can i make it give me also the payment that paid but still didn't have a invoice ??

Thanks!
