Subject Re: Auto calculation of price based on cost of material and labor.
Date Mon, 26 Jun 2006 04:43:00 GMT
Rohit,

Because your data file source for costs, minimum sales
price, etc is going to be unique to each company (or
at the very least industry) there is no standardized
way to do this.  What you'll want to do is create a
service that will update the ProductPrice entity for
the product's minimum price, cost, etc.  Then, you can
create Price Rules based on a markup over cost.  That
service isn't going to be something that standardized
enough to be in the OFBiz project, I wouldn't think.  

I have no real knowledge of what they're doing with
the BOM and manufacturing webapp, so as BJ says, there
may be a solution there as well.
