QWebException: ('AccessError', u'Sorry, you are not allowed to access this document.

I must re-add for "Public" and "Portal" these Record Access Rule:

stock.warehouse, Product Template

stock.location, Location ,

stock.move, Stock

stock.quant, Quantities,

product.uom, UofM Products,

sale.order

sale.order.line

But What kind of python script can remove these Record???

Probably you are accessing unpublished product through link.. Otherwise you changed something..

This should work out of the box. What did you change?
