1. The document describes how to create a workflow in Open ERP 7 including defining states, buttons, activities, and transitions. 2. States are added as a selection field to the model. Buttons are added to the form view to trigger workflow activities. 3. Workflow activities are created and linked to the model. The first activity sets the initial 'draft' state. Additional activities define actions like approval steps. 4. Transitions connect activities and define the signals, like a button click, needed to move between states in the workflow.

1. OPEN ERP 7
CREATE A WORKFLOW

2. STEP BY STEP
1.Create state in column fields
2.Create button and field in form view
3.Create workflow activity
4.Create workflow transition

3. CREATE STATE IN COLUMN FIELDS
class crossovered_budget(osv.osv):
_inherit = "crossovered.budget"
_description = "inherited to crossovered.budget"
_columns = {
#other fields
'state' : fields.selection(
[('draft','Draft'),
('cancel', 'Cancelled'),
('check','Wait Approval Manager'),
('authorize','Wait Approval Dir Opr'),
('authorize_finance','Wait Approval Dir. Fin'),
('confirm','Wait Approval Finance'),
('validate','Validate'),
('done','Done')],
'Status', select=True, required=True, readonly=True)
}

4. CREATE BUTTON AND FIELD IN FORM VIEW
<header>
<button string="Confirm1" name="confirm" states="draft" type="workflow" class="oe_highlight"/>
<button string="Approve" name="check" states="check" type="workflow" class="oe_highlight"/>
<button string="Wait Approval Manager" name="authorize" states="authorize" type="workflow"
class="oe_highlight"/>
<button string="Wait Approval Dir. Operational" name="authorize_finance"
states="authorize_finance" type="workflow" class="oe_highlight"/>
<button string="Wait Approval Dir. Finance" name="confirm" states="confirm" type="workflow"
class="oe_highlight"/>
<button string="Done" name="done" states="validate" type="workflow" class="oe_highlight"/>
<button name="draft" states="cancel" string="Reset to Draft" type="workflow" />
<button string="Cancel Budget" name="cancel"
states="check,authorize,authorize_finance,confirm,validate" type="workflow"/>
<field name="state" widget="statusbar"
statusbar_visible="draft,check,authorize,authorize_finance,confirm,validate,done"/>
</header>

5. CREATE WORKFLOW ACTIVITY
<record model="workflow" id="wkf_crossovered_budget">
<field name="name">wkf.crossovered.budget</field>
<field name="osv">crossovered.budget</field>
<field name="on_create">True</field>
</record>
<record model="workflow.activity" id="act_draft">
<field name="wkf_id" ref="wkf_crossovered_budget" />
<field name="flow_start">True</field>
<field name="name">draft</field>
<field name="action">write({'state':'draft'})</field>
<field name="kind">function</field>
</record>

6. CREATE WORKFLOW ACTIVITY CONTINUE
<record model="workflow.activity" id="act_done">
<field name="wkf_id" ref="wkf_crossovered_budget" />
<field name="name">done</field>
<field name="flow_stop">True</field>
<field name="kind">stopall</field>
<field name="action">budget_done()</field>
<field name="join_mode">XOR</field>
</record>

7. CREATE WORKFLOW TRANSITION
<record model="workflow.transition" id="t1">
<field name="act_from" ref="act_draft" />
<field name="act_to" ref="act_confirm" />
<field name="signal">confirm</field>
</record>
<record model="workflow.transition" id="t2">
<field name="act_from" ref="act_confirm" />
<field name="act_to" ref="act_validate" />
<field name="signal">validate</field>
</record>
