In Architect, create a collection variable in the task editor’s Update Data data action. The types of collections you see may depend on the flow type that you use. In the Update Data action’s design area, add an update statement and choose to create a Collection. Next, select the collection’s data type. 

On the design form, Architect creates a variable name | value-to-assign pairing. When you enter the Variable Name, Architect creates either a flow level variable or task level variable, based on the entry. If the entry matches an existing variable name, Architect uses the existing name instead of creating a new variable.

Note: Under Initial Value, you can set the literal value, or from the list choose Use default. When you choose to use default, the value is NOT_SET.
  1. From the Architect home page, click or hover over the Flows menu and select the desired flow type.
  2. Create a new flow or select an existing one. The flow’s configuration page opens.
