SAP Workflow: Workflow log not appearing in Workflow Overview and Rejection text/reason also not coming as attachment under 'Services for Object' button

Hello Gurus,

My workflow log is not coming in workflow overview of the document for which the workflow gets triggered. Even the rejection message also not coming in attachments section of the document.

The document here is the Down Payment Request created for a PO.

I have done the binding too from container to task for BOR and also for _Attach_Objects.

Please suggest and help with your valuable inputs !! Thanks
