Question:
I have a SSIS package which has some execution problem in production environment and I need to check it and perform debugging on my local machine, however when I add the package into my SSIS project and open it in BIDS, my BIDS hangs for a long time.
 
Answer:
This issue is usually caused by the fact that your SSIS package is complex with many tasks including many connection managers. When you open the SSIS package in BIDS, by default the validation process on each task will start. Since your SSIS package is copied from another place, the connections may be invalid. In this case, the validation process will spend a lot of time and cause the BIDS not working during this time.
 
To resolve this issue, you can do as follows:
1.Before you add the SSIS package, select your SSIS project first, then click the SSIS menu, and change your SSIS project to Offline mode by checking "Work Offline".
2.Add your SSIS package to the project and change each Task's DelayValidation property to True.
3.After these steps, you can modify the connections to be valid based on your local test environment.
