We have several apps used to extract and transform data into QVDs. These apps contain the same script within their data load editors. But this script now needs amending and I will have to repeat the process for each app in turn.
Ideally, I would like to have just one piece of script which our ETL apps could call within their load editor (e.g. like a SAS autoexec file). So when it came to maintaining the script I would only have to update in one place.
