3736482 - Workflow restart BADI MMPUR_PO_WORKFLOW_RESTART fiori app vs me22n

In SAP standard it is possible to control the conditions under which a workflow restart is triggered via the the configuration node 'Manage Conditions to Restart Flexible Workflow for Purchase Orders' (SSCUI 103345) 
Where additional business conditions are to be considered it is possible to implement additional control using the BADI MMPUR_PO_WORKFLOW_RESTART. 
When implementing BADI MMPUR_PO_WORKFLOW_RESTART it is observed that a different restart behavior occurs between Fiori apps 'manage purchase order' and webgui apps 'Change Purchase Order' (ME22N)
