Avoid cyclical dependencies. Be careful not to create cyclical dependencies among your processes. For example, your flowchart has a Select process that provides input to a Create Seg process. If you choose as input in your Select process a segment that will be created by the same Create Seg process that the Select process provides output to, you will have created a cyclical dependency. This situation will result in an error when you try to run the process.

Applying global suppressions. If your organization uses the global suppression feature, be aware that a particular set of IDs might be automatically excluded from use in target cells and campaigns.
