Hello,

On my side all works as expected, instead of the « Purchase Orders » button ( the one that show you all the purchase orders, purchase_amount_total field), i have this error when trying to click on it 

The above exception was the direct cause
of the following exception:
 
Traceback (most recent call last):
  File
"/opt/odoo/odoo/odoo/http.py", line 641, in _handle_exception
    return
super(JsonRequest, self)._handle_exception(exception)
  File
"/opt/odoo/odoo/odoo/http.py", line 317, in _handle_exception
    raise
exception.with_traceback(None) from new_cause
ValueError: External ID not found in the
system: purchase.action_orders

Sales buttons work, i can click on sales quotation and sales orders, for purchase i can only click on purchase quotation, so after validating my purchase quotation (and so becoming an order), i cant see it from my lead anymore

Thanks by advance for your help

Easy to install, and adds functionality we think is really useful: to see which products we're expecting to sell on an opportunity in CRM. 

PPTS were very helpful when I had a query, and have already improved the app.
