Hello Cédric and thanks for reply.
I did the test creating the payment method from the menu financial - configuration journals - invoice payment methods and created new accounts but at the time of making the payment did not show me the method of payment.
Then I tried to create the payment method from the search method payment and something strange happened, pressed the new button to go to the payment method form: enter the name, journal but when I went to the debit account or credit account it did not show none of the accounts.
I started and created a new account for debit account and added it but when I went to add the credit account it did show the accounts, but when i did click account to add it, that action deleted company name and deactivated the company field.
Note: Before adding the debit account or the credit account in the search form, no account is shown, accounts are only shown when I add one of them first (debit or credit account).
