Hi,
I want to sync the technical system details from Central SLD into local SLD, so I added a local SLD in the Central SLD with following method
You should create a data supplier bridge in you Central SLD. Which you have already done.

check in logs of SLD .. in Administration.. Also to transfer SLD content from one SLD to other..
both SLD should be at CR and CIM Level.. Please check that..
Also manual way of transferring content is taking a export and import
Thanks
