Hi,

I inherited the class purchase_order and wrote my method _prepare_inv_line to override the one of the class, but when I ran the code it was not called.

The question is, why this method was not called,

second, how to override such functions ?

Here is my own method I inserted in the inherited class purchase_order

	def _prepare_inv_line(self, cr, uid, account_id, order_line, context=None):
		res = super(purchase_order,self)._prepare_inv_line(cr, uid, account_id, order_line, context)
		line = self.pool.get('purchase.order.line').browse(cr,uid,order_line)
		if not line.order_id.requisition_id:
			""" get the account # defined as reserved for this department """
			account_obj = self.pool.get('account.account')
			acct_id = account_obj.search(cr,uid,[('department_id','=',line.order_id.department_id.id)])
			res['account_id'] = acct_id
		return res

I'm OpenERP 7.0

in this method if the PO is not linked to a Purchase Requisition then I have to get the account id from the chart of accounts that is related to the department of the user initiated the PO

This method has not been visited when I ran the code

thx in advance for help
