Hi,all:
As we know in 'Project' module we have 'partner_id' as customer(related to res.partner),then I add a new field in res.partner called 'created_time',then when create a project I should check customer's created_time,if our customer is not created for more than three months,this project is not supposed to be created,so how should I use res.partner's created_time in project module?
Thanks for your help.
