Hi everybody,

I have the current problems describe below ( OpenERP 7) :

If I create an invoice for my sale order and I canceled it, I can only recreate the same sale_order.

However, it happen that someone created a full invoice and want to cancel it to create a invoice per percentage.

Is it possible to "go back" in the workflow like before created the first one?

So in the stage "wait_invoice"?

I was thinking do some transition like this:

        <record id="trans_wait_invoice_invoice_manual" model="workflow.transition">
            <field name="act_from" ref="act_invoice_except"/>
            <field name="act_to" ref="act_wait_invoice"/>
            <field name="signal">invoice_reset</field>
        </record>
        <record id="trans_wait_invoice_invoice_manual" model="workflow.transition">
            <field name="act_from" ref="act_invoice_cancel"/>
            <field name="act_to" ref="act_wait_invoice"/>
            <field name="signal">invoice_reset</field>
        </record>

My signal is a button :

<button name="invoice_reset" string="Reset Invoice" type="object" attrs="{'invisible': [('state', '!=', 'invoice_except')]}" groups="base.group_user" />

Someone knows why it is not working? Any idea to correct it? Or another way to resolve my issue?

Many thanks,

Selverine
