Introduction

Attached is a demonstation app on multiple approvers for Joget DX. This app gives you an example on how to create an approval flow that requires ALL approvers to "Approve" the request and not just one approver. If anyone rejects the request, the whole approval process would be rejected.

Steps:

  1. Click on "Apply (Run Process)" menu and submit. The app has set the approvers by default to "admin" and "cat".

  2. Login as "admin" and "cat" to perform then approval.

  3. In the final activity, you can view the audit trail of all the approvers. Click "Complete" to end the process.

For the process design, we would require two separate workflow processes: "Approve" and "Apply".

The demonstration Multiple Approver app for Joget v6 or earlier will not work in Joget DX if the "Run Process Primary Key" is set to "UUID" ( see General Settings > Run Process Primary Key ). If you are using Joget DX or newer, do download and use the attached app below.

Figure 3: Mapping of ApproverGroup

Each of the "Approver" process instances would gather decision from the respective Approver. Then, Update Application will execute to trigger Waiting For Response activity in the parent process ( Apply" Process ) which will then execute the Process Approval tool to evaluate if it is enough to make a final decision and move forward.
