Sharing custom variables between tasks in a package.
In this example, I’ll illustrate the use of a package-level variable being shared between ForEach Loop Container and Script Task Control Flow tasks.
This package will iterate through text files and display the name of each to the user.
As I explained in my Overview of Variables article, I’ll begin by adding an new Package Level variable and naming it Filename.
Next, I’ll drag a ForEach Loop Container Control Flow item unto the designer and configure it to loop through text files in my source folder.
For its Variable Mappings, I’ll select the Package-level variable I added in the first step.
Now I’ll drag a Script Task into the ForEach Loop Container configure its ReadOnlyVariables to use the package-level variable.
I’ll program the script to display the name of each file in my sources folder.
By executing my package, each file found in my source folder is displayed to me in a pop up window.
