Negative payments without bank Info

[Former Member]

Hi,
We using the procedure of Negative payments: we recorded customer documents with mode of payment incoming C3 (Which Has Been linked on the payment Outgoing F3).
On both of Payment (C3 and F3) has inserted a generic bank 'not real', with generic accounts and no information IBAN / Account.
From the wizard Payment, in step 5, We select the mode of payment C3 and set a real specific Bank (Present in the Banks setting).
Payment is recorded on coge generic and not on what you selected in step 5 and the Creation of the test file to the bank we have the Following Error:

<IBAN>- Company House Bank: Value "" violates the expected format "[a-zA-Z]{2,2}[0-9]{2,2}[a-zA-Z0-9]{1,30}"

Payment Information- <IBAN> - value is missing

<BIC>- Company House Bank: Value "" violates the expected format "[A-Z]{6,6}[A-Z2-9][A-NP-Z0-9]([A-Z0-9]{3,3}){0,1}"

The same payment F3 with the generic bank or no indication of the bank, is used without problems for Generation vendor payments and the creation file of bank.

Ideas??
Thank you
