The Union activity allows you to regroup the result of multiple activities into a single target.
The sets do not necessarily need to be homogeneous.
The Union activity is used to combine the populations from inbound transitions when performing a segmentation, defining an audience, or when preparing the message target for example.
Drag and drop a Union activity into your workflow.
Connect it to the other activities that come before it, such as queries.
Select the activity, then open it using the button from the quick actions that appear.
Select the Reconciliation type to define how duplicates are from the confrontation between inbound populations are handled:
Check the Use common additional data only box if you would like to keep only the additional data that is in all inbound transitions.
If you would like to limit the size of the final population, check the Limit size of generated population box. The size can be specified in the Maximum number of records field.
If needed, manage the activity’s Transitions to access the advanced options for the calculated population.
Confirm the configuration of your activity and save your workflow.
The following example shows the result of two query activities that aim to regroup profiles from the Adobe Campaign database who are between 18 and 27 years old and those who are between 34 and 40 years old. The result contains all the profiles of the two queries or the maximum number of records, if applicable, as specified during the configuration.
