For Each looping issue question.

I am maintaining some SSIS packages for a client. The master package goes out to MDS and gets a list of companies that are "active" from an mds entity view. The package then loops through multiple ETL packages for each company in the list. The logic works fine most of the time however when the client adds a new company to the MDS entity and set it to active some of the ETL packages do not run correctly until I manually execute the package for the specific company. Does anyone have any ideas why this would occur in a for each loop in SSIS?
