This function enables users to push design changes to their sleeping process instances. 

Consider the following scenario. 

On the Process Definition page, select the process from the table and click on the Actions - Design menu option.

The definition is opened in the designer canvas. 

Generate and execute a new process instance. 

You can now confirm that the instance is “sleeping” on the Process Instance page. 

Navigate to the Process Definition Designer page and make the design changes shown below. Then, save the process definition. An alert notification message appears in the top right corner. 

Go to the Process Definition page. Choose the previous process definition and click on 'Utils' - 'Update Waiting Instances'. 

A pop-up window appears for configuration, indicating the number of instances affected by the design changes. Select the "Re-Execute Waiting Steps" checkbox, then click Update to confirm. Note: Choosing “All” will re-execute all the “sleeping” steps. Selecting “Changed” will only re-execute the modified “sleeping” steps. Picking “None” means no “sleeping” steps are re-executed. Click the Update button to start. 

A confirmation message shows the total number of instances being updated. 

Navigate to the Process Instances page and select the process instance by name. Use the Search box to narrow down the result list. Then, click on the View—Render menu option. 

The process instance appears on the new page. The design changes applied are shown below.  

Alternatively, you can update the design from the Process Instances page. Select the process instance and click the Utils - Update - Design menu option. 

A pop-up window appears for confirmation. Select the "Re-Execute Waiting Steps" checkbox. Click Update to confirm. Note: Selecting “All” will re-execute all the “sleeping” steps. Choosing “Changed” will only re-execute the changed “sleeping” steps. Selecting “None” confirms no “sleeping” steps will be re-executed. Click the Update button to proceed. 

The pop-up window reappears, confirming the changes. Click OK to continue.
