The version I should be looking at will do all except variants (attributes).
Once you start looking, there are several versions of the OSC connector in existence, branches done by different companies, highlighting one of the "problems" with Openerp: the sprawl of individual modifications of modules, and the lack of guidance by the Openerp S.A. Makes it very confusing for the newbie.
I have so many other things to busy me, I am avoiding doing anything with this OpenERP issue, for reasons not relevant to this thread.
The only detailed documentation that exists on this connector is mine. Send me a pm and I'll share you the google doc.
