Dears,
Usually, Upon Validating an invoice, it takes a new sequence from sequence (e.g. SAJ/%(year)s/), and in case that invoice has an internal_number (case of canceled invoice set to draft), it should use its internal_number. But the unwanted behavior now is when validating a draft invoice - previously canceled - the system generates new sequence number. I need to re-use the existing internal number.
Thank you,

The problem was from a configuration in the Journal (account.journal) . Every time I validate an invoice it will create new Journal entry with new Sequence number (e.g. SAJ/2017/55545), so I unchecked the Autopost Created Move. Now. when I attemp to validate an invoice already canceled it will use it's existing internal_number as invoice number.
========================
Scenario:
-create invoice, INV number N1 is assigned to inv
-state goes to OPEN
-cancel the invoice then set to draft: the number disappear from the interface
-validate the invoice -> new number became the same existing N1
