S/4HANA Flexible Workflow: How to print Workflow Details on the very first PO PDF output?

Hi everyone, We are facing an issue trying to get the Approver’s Name and Approval Date to print on the very first automated PDF output right after a Purchase Order is approved via the Fiori My Inbox app. We understand that since it’s the first print following approval, data won’t be available in Workflow tables (i.e. I_WorkflowStatusOverview) yet, so using BAdI MM_PUR_S4_PO_MODIFY_HEADER would not take effect unless PO is changed.
