recently we've started setting up OpenERP for our three companies. We have a multi-company envorinment with three companies. Sometimes it happens that we have intercompany projects, company 1 has a project linked to a customer but company 2 also has this project but the customer does not know this. So company 2 must send his timehseets to company 1 so company 1 can invoice the timesheets to the customer. I have searched for a module for intercompany project but I did not find anything. I think maybe this problem can just be taken care of within the system without an extra module, please help me?
