Master / Slave ECC System - Impact on BW

We have several instances of SAP and are looking at making one system the primary master data system that updates the other systems. So master data is created on the master system and it is then transferred to the slave systems. So, for example, materials will exist on both systems - same key and attributes etc.

At the moment our BW system links to all SAP instances and take master data from all SAP instances. Thinking aloud, other than duplicate data, are there any obvious issues that might arise from this scenario?

Thoughts gratefully received.
