Hi, I have a problem with the Purchases Module of Open ERP 7.

I have made a Purchase Order. I received the material and i recorded the same in Purchases module, i Received the invoice and recorded it as well. still when i go o purchase orders and go to the particular Purchases order, the status is not converted to done but stays as Purchase order and i get the option to receive the invoice even though i have already recorded the invoice.

When i press the receive invoice options, it takes me to the invoice i already recorded.

I am unable to change the status from Purchase order to Done for all my Purchases orders.

How can i fix this issue.
