title: SSIS 2012 "Global" Variables
body: <p>I'm running into an issue trying to pass data into a child package.
  My parent package runs through a db, checks it against another in order to run or not. Currently i'm using a ForEach Loop in order to do so. I then can identify the row i need to run by one unique id. Then i pass it to the appropriate child package to process it.</p>
  
  <p>My question is, what's the easiest method of writing that identifier to a 4 byte variable so that it is available on a solution level, instead of package level. I can't pass anything through to the child package as far as i have seen either.</p>
  
  <p>Thanks for assist!
