Prohibit Self Approval for Requisition and PO is not same

Summary:

Hi Team

We did below setup for Document Approval(PO) and ReqApproval (Requisition)

• Go to the Setup and Maintenance work area.
• Search and open the Manage Task Configurations task.
• Search for your specific workflow task in the BPM Worklist.
• Click the Edit task icon and select the Configuration subtab.
• Find the Prohibit User Self-Approval section.
• Check the box for Prohibit self-approval by users named in these payload attributes.
• Add the relevant payload attribute (e.g., /task:task/task:creator or the specific requestor field).

But what we obvserve is
For PR, if for a PR only approver is creator then PR is getting Rejected but whereas for a PO if only approver is creator then its getting auto approved
