Storing derived fields

Store a derived field if you want to be able to use it in another process in the same or a different flowchart.

About this task

Derived fields are variables that do not exist in a data source; they are created from one or more existing fields, even across different data sources. A derived field is available only within the process where it was created. It is not available in any other process (except an immediately following process if Make persistent is enabled).

If you want to store a derived field definition so that you can use it in other processes and flowcharts, follow the procedure below.

Procedure

  1. From the configuration window of a process that supports derived fields, click Derived fields and create the derived field that you want to store.
    For example, define an expression such as (Balance / Credit_limit) * 100.
  2. In the Create derived field dialog, open the Stored derived fields list and select Save current expression to stored list.
  3. Use the Save derived field expression dialog to specify whether to save the expression in a folder. You can assign a security policy and optionally change the expression and assign it a different name. The expression that you save will be stored in a list that you can access when you configure other processes and flowcharts.
  4. Click Save.
