SSIS(change connections at run time from Parent to child package)

Hi,

We have 2 ETL packages (parent and child)

We are calling child package multiple times from the parent package. Child package is called 9 times in parallel from the parent. We are passing ODBC DSN name as a parameter to the child package to connect to the source system. Parameter is passing correctly (from parent to child) as we have checked it using the script task. But we are unable to determine if the package is connecting to which "data source" at a time while bringing the data.

we have 9 different ODBC connections for 9 different sources(branches)

In SSIS child package we have kept only one connection and wants that to be changed based on the parameter value(9 different values like MiamiSourceValue1, NewYorkSourceValue2...) passed from the parent package)

We are unable to change the connections at run time.

Please help me out, as badly stuck in this problem.

Thanks

Shailendra
