You should create the location D as child of of Location C. Creat and initialize the locations then change the Parent of Location D as Location C.
Read the Global Admin manual.
Thanks for the response.
I've gone through the manual and tried to have kind of combination what i explained in my previous post.
I wanted to understand whether the DBs which are Secondary at Satellite C can be allocated to Satellite D by Satellite C.
I was not able to do the allocation.
Will I be able to create Extracts of DB from a satellite C and allocate it to Satellite D ( Sorry only Hub license is with us no satellite lic so could not test this)
