Consequences of different Company Codes in Networks and WBS
I'm aware that we are able to use many different Company Codes in a Project (while they all have the same Controlling Area) in multiple ways.
But what's the point of having the network header assigned to a company code and its activities to a different one? It must be some consequences worthy to keep in mind, which?
And why network's company code can not be changed while WBSE's can?
