create a new sequence :

Settings>>Technical>> Sequences & Identifiers>>Sequence Codes. image description then

Settings>>Technical>> Sequences & Identifiers>>Sequences. image description

then create a new module to add a Employee Code

class hr_employee(osv.osv):
    _inherit = "hr.employee"

    def _get_code(self, cr, uid,context, *args):
        obj_sequence = self.pool.get('ir.sequence')    
        return obj_sequence.next_by_code(cr, uid, 'hr.employee.sequence', context=context)

    _columns = { 'code' : fields.char('Code', size=64), }

    _defaults = { 'code': _get_code, }


you can define this sequence in your module :

my_module_data.xml :

<?xml version="1.0" encoding="UTF-8"?>
    <data noupdate="0">
        <record model="ir.sequence.type" id="hr_employee_code_sequence">
            <field name="name">Code sequence hr employee</field>
            <field name="code">hr.employee.sequence</field>
        <record model="ir.sequence" id="hr_employee_sequence">
            <field name="name">Sequence For employee</field>
            <field name="code">hr.employee.sequence</field>
            <field name="active">TRUE</field>
            <field name="prefix">EMP</field>
            <field name="number_increment">1</field>
            <field name="number_next">1000</field>
            <field name="implementation">standard</field>

and in __openerp__.py:

"init_xml": ["my_module_data.xml"],

I have an error Constraint Error

code must be unique

you can define a another sequence just replace <field name="code">hr.employee.sequence</field> to <field name="code">hr.employee.sequence2</field>

In odoo9 we can create a sequence code:

Create a new module name prod_quantity

 class prod_quantity(models.Model):     
  _name = 'products.car'

q_serial_no=fields.Char('Quantity Serial Number',default=lambda obj:



     <field name="q_serial_no"/>


 Create a new view file :


<data noupdate="0">

<record model="ir.sequence" id="product_sequence">

<field name="name">Sequence For Product</field>

<field name="code">products.car</field>

<field name="implementation">standard</field>

<field name="active">TRUE</field>

<field name="prefix">QTY</field>

<field name="padding">3</field>

<field name="number_increment">1</field>

<field name="number_next_actual">1000</field>




Apply view file in openerp:

'data': [
