Hi there, I want to manage a BOM where a part of the work is done by a contractor.

For the sake of example let's say that I build a hammer made of a head and a handle. I make the first part of the manufacturing, cutting a handle. Once cut, I need the handle to be sent to a subcontracted painter who'll paint the handle. I'm looking for how to model this in OpenERP knowing that I need to track:

• The sending to the painter via a transporter (take 2 days and costs 10 coins to send, then 1 day and 5 coins sending back)
• The fact that painting takes 3 days, and costs 5 coins, that I receive a painted handle

How do I manage to track the manufacturing time? How do I update this planning knowing that after I sent the handle, the painter tells me that he's gonna have 2 days delay?

I guess that's a pretty wide question, but I've tried fiddling with the native tools, and the only solutions I find imply quite heavy development. If it's unavoidable, no worries, we'll go for it, but even that way, there may be some suggestions about how to approach the problem.

Any hint welcome!
