Initialization question

hai all,

I have a QA system that has been just released after upgrade. It is nothing but a copy of production. So, the source system and initialization are for production servers. Now as this is QA, the connetions are only for R/3 QA only. I am trying to initialize and load data but its allways giving me a short dump and terminating it.

My question is:

When a system has initilization and data from a different source system, can I create another initialization for another source system and load deltas? Or is initialization specific to data targets?
