title: Execute different SSIS packages based on Flat File name
body: <p>I have several SSIS packages that parse different files into their respective tables. Using SSIS File Watcher task, I want to create a master package that will check a folder for the files and then select the proper sub package based on the OutputVariableName using a precedence constraint. I'm not sure how to write the expression to set the variable correctly. I want to set it based on a FINDSTRING() in the file name.</p>
