I am following the Wrox book by Brian Knight and others. I am building a For Each Loop container for a data flow task. I am following the steps in the book but when I get to the step on page 140 that says assisgn my User variable to ConnectionString I dont have ConnectionString as one of my choices.
I have added the loop container, dragged my task onto it, assigned the variable and location of files. I am no on propererties of my data flow task under Expressions and am in the Property Expressions Editor. This Property drop down box does not have ConnectionString. Did I miss a step???
