Enabling SSIS Packages On Demand

In work with a current client, they required that the execution and processing of certain packages to be configurable via a web interface.  In my case, I wanted to proactively enable/disable the importing of certain data sources.  If a source system goes down or is in maintenance mode, I need to be able to shut off the import process for that one and still updated the data warehouse.   By using SSIS Configurations, Variables, SSIS package expressions, I was able to allow an administrator to control which packages (i.e. the data source importing) were going to be processed.

Trial Run: Using the Precedence Constraint 

One possible solution that I considered was using the precedence constraint to determine if the package should be executed or branch to another path (or ignore all together).  Something like this:

Ignore the Script components, but think of them as Packages calling other Packages

However, this didn’t really meet my requirements.  I just needed to read from SSIS Config table and then enable/disable the child package.

The Solution

Here’s my solution:

1. Create the SSIS package variables

2. Your SSISConfiguration table will be updated with the variables.

3. Update your SSIS package to contain sequence containers and any dependencies.  In my case, I needed run SalesForce updates after the other stuff.

* Notice the pink triangle in the upper left corner.  This is the notification from BIDS Helper to let the developer know that there is an expression used in the property section of the package

4. Update the Package Component Expressions section to Enable/Disable the package when reading from the Variable.  I need to use the “!” expression to reverse out the boolean value.  I am using the DISABLE property of the component, so if it is TRUE, then that means DISABLE it, but I want the reverse.

5. Now update your SSIS Configurations with the property boolean values and run the package.  You will see that the variable will enable/disable the execution of the package when you need it.


I hope you’ve found this helpful. Feel free to contact me at if you have any questions and look forward to my next post.
