Before creating the workflow definitions in the system, be ready with the list of approvers whom can process the workflow tasks. This blog post describes about how you can enable the approvers and assign them to people picker(agent list) present in the workflow definition.

Firstly, we should understand how the employees are maintained in the cloud environment.The following diagram covers all important aspects needed to handle workforce, both employees and contingent workers in SAP S/4HANA Cloud.

Using either one of the mechanisms, maintain the employee data in the cloud environment and make sure that the following has been maintained.

• Employee master data.
• Workassignments with active validity date.
• Supervisor/manager assignment.

Please go this link for the detailed information.

Once the employee master is created, there comes the part of assigning the right roles to the selected approvers.The system administrator needs to add the manager role to the user because this role is required to use the My Inbox – application to approve/reject the workflow tasks. For example, if the selected employee is the approver of any purchase order then the his/her profile should have SAP_BR_MANAGER or SAP_BR_PURCHASING_MANAGER roles.

After completing these steps, then the people picker present in the workflow definition will have the list of approvers/agents.
