SSIS 2012 pass values from child package to parent with project deployment model

Question

i\'m using the new project deployment model.

I have a master package called ETL. The first thing my ETL package does is run a package called get SFTP files as shown

Answer 1

The Simple Solution is

Add The Variables in Master Package (which Needs Back to use in Master)

Assign Values in Child Packages to Master Package Variables (Access no issue in child for Master Package Varibales)

And Once Control came back to Master Used them ...and because they are declared in Master Package you can use their values which were assinged under Child Packages
