The attribute only active the historisation on the records of the Models but the only way to access the historized data is by setting a _datetime in context. But in some cases like in sale_opportunity, you want to have read access on those data (or a subset). For that you must create your own Model that will use a SQL query as table. As this query is not generic and depends of the business cases we can not provide a default one. -- Cédric Krier B2CK SPRL Rue de Rotterdam, 4 4000 Liège Belgium Tel: +32 472 54 46 59 Email/Jabber: cedric.kr...@b2ck.com Website: http://www.b2ck.com/
