Update default_data_transaction_number.xml

<record>
<name>ATM</name>
</record>
On the Portuguese translation that option doesn't exists... Any reason?
And about a credit option? (i have send you a email, doesn't make sense appear the debit option on a credit transaction but the credit option. (just an idea i hope you don't get upset with me)
