TEM SUA 2.0 ETL process has been redesigned as compared to SUA 1.3 in order to prevent users from accessing the SUA UI access and usage during ETL. Therefore the ETL process is a bit longer than what used to be in SUA 1.3 (the first one) but users are not bolcked from using the UI.
Further ETLs are usually faster as well as catalog updates.
Can you specify which ones
We are going to add this capability back in as part of coming content update within 1Q2013
As to TEM SUA 2.0 the catalog updates will be provided via Fixlet content streaming. This will occurr shortly when we are going to deliver the first catalog update for TEM SUA 2.0.
This capability is not there yet but we are looking for adding it in the future updates of TEM SUA.
Working on those to be made available within 1Q2013.
