We have created a principal site and 3 other sub site (correspond with 3 different compagnies).
In principal site we want to put all informations related to our company.
When we enter a second-hand cars’ (VO) list, we need to dispatch this cars in the 3 sub site (company A, compagny B, compagny C).
Ex : Ford à company A
Peugeot à compagny B
Citroen à company C
Audi à compagny A + C
When you update VO list, this automatically update the 3 other sub site. How to do this ? We want to use Designer but someone say us that you can use this only for a principal site not for 3 or more sites.
After, if someone want one car, he can put as an option and this information must go up in principal site.
