Global-Child project cost transfer and capitalization

Hi,

I would like to highlight a scenario in Project Costing and seek your advises/suggestions on the same.

Assume, we have 5 Operating Units like S1,S2,S3,S4 and S5. We would like to Create Global Project (Parent Project: P1) in one Operating Unit S1. Once we Create Global Project in S1, it should be  visible across all the Operating Units. Based on this we want to track all Labor Cost and Supplier Invoice under Global Project across multiple Operating Units as shown in illustration below.

S1 -LABOR COST  -$2500; S1 -SUPPLIER COST   -$3000

S2 -LABOR COST   -$4000; S2 -SUPPLIER COST  -$1000
