    RPC_DISCONNECTED…the dreaded “The object invoked has disconnected from its clients.” issue. There are a ton of causes to this, looks like you’ve covered the global variables issue with Excel.. Can you put the first ReleaseCOM(ReportSheet) below ReportBook(Close) and run it? Also, check out this.
