You can push process design changes to the “sleeping” process instance(s). 

These design changes can affect workflow steps that have already been completed or are in progress. 

Let's examine the example of the workflow process below. 

You need to create and execute a new process instance. Click the “View Instance” hyperlink to view the process instance. 

The process instance is displayed on a new page, and the status is “sleeping” at the “Task” step. 

You need to return to the process designer and modify the workflow design. Save the process definition. Note: Design changes are significant when applied to a process path that has not yet been executed. 

On the process instance page, select the “sleeping” instance, then click the Utils > Update > Design menu option to apply the design changes. 

You can also apply the design changes on the Render Instance page. Select the Utils > Update > Design menu option. 

A pop-up window appears for confirmation. You can choose to re-execute “All, Changed or No” waiting steps by selecting the appropriate buttons. Click the OK button to continue.  

The design changes have been applied, and an alert is displayed as shown below. 

You can render the process instance to view the design changes. 

Design changes are recorded in the process instance's history log. Select the process instance, then click the Utils > History menu option. 

The Process Instance > View history tab shows the design updated event as shown below. 

Note: Values passed to variables or globals in a process instance through the API are retained by default, regardless of whether they are correct.
