  It sounds like the staging tables are fairly small though. When they are small, individual insert selects will run quite quickly and it will be a similar time to get the job done if you just launch them when the data for that store is avalable and allow them to sequence through.  


Appreciate the response.

Are you indicating that as data for some group of Stores arrive we "build" a UNION statement comprising only those source tables manually and then Insert/Select?

That option may not work as we are trying to build a fully automated process. Am I missing something here ?


Thanks.
