Cproject structure with cross-company resources

Hello All,

Kindly guide as what will be the best C-Project structure to

handle the below which might involve:

1. Resources from Multiple Company codes under same controlling area

2. Resources from Multiple Company codes under different controlling area

My scenario is a New Product Development scenario in which resources from

multiple part of the world will collaborate. It also needs accounting integration

with Backend WBS elements, time confirmation need to happen using CATs. Should multiple CProjects need to be created and

for each company code (as a sub project) and connected using Tasks assigned to Sub Projects ???? Please guide.

Thanks,

Sachin
