Append to Array

An array is a series or list of data elements of the same type. You can add a single data element to an array with the append action available in the data mapper. For example, you can append strings to a string array.

The append action is available in the Data Association editor for both structured and dynamic processes.

Ensure the following:

  • The target expression type must be always an array.
  • The source expression type must be of the same data type as the target array.
  • Both the source and target expressions have to be valid.

To append to an array while configuring data associations:

  1. Select an activity in a process that needs data association and click More Options.
  2. Select Data Association and choose either Input or Output.
  3. Drag and drop the data objects into the input and output fields to configure an association. You can also begin typing and select from auto complete entries that display.
  4. Click the data association icon, and in the resulting dialog toggle the Append button.
    The data association can be valid or invalid.
