SSIS: Working with 3 constrains where 2 should be OR and one should be AND So I have an SSIS flow in which I am working with three constraint within a task, but 2 of them must be an OR and one must be an AND. In pseudo-code would be something like:

if ( (constraint-a OR constraint-b) AND constraint-c)


Problem is, we can only set OR/AND to all precedents:



Are there any solutions in which we could group some of these constraints?
Here is my original solution for this problem, which apparently is not as bad as I thought. The only problem with it is that the designer canvas can get quite crowded.

I managed to achieve the desired solution with a little kludge, which gives me exactly what I want. However I can't help but feel a little dirty doing it, so I wonder if there is a better way. Here is a diagram of what I have done:



NOTE: It is important to emphasise that I need Main Script B to start as soon as Main Script A completes.

Script Task B1 is the one requiring the complex constraint. As you can see in the centre of the diagram, I grouped failure of Main Script A and completion of Script Task A2 in an empty container.

This allows for script tasks A1 and A2 to be bypassed if Main Script A fails, and Script Task B1 to be executed after previous script tasks have been completed. But Script Task B1 must wait for Main Script B to finish as well.

Here are the results using this cheap kludge:

When Main Script A succeeds:


When Main Script A fails:


I wonder if there are alternatives to this solution, though.
