The Concatenate action allows you to create a list by merging the data of two other lists.
Concatenate was previously called Concatenate Lists.
As a PROCESIO user, I want to have an action that concatenates 2 lists (the lists can be simple or DM). The action outputs a new list containing values from both input lists.
The example requires a process with just the Concatenate action with the following configuration.
Step 1. Create a new process and give it a name.
Step 2. Drag the Concatenate action to the canvas and link it to the other actions.
