Dear Experts,
After configuring all the necessary customizing in ECC (releasing, workflow, authorization) and the Gateway (scenario definition and authorization) and checking the gateway if it can receive the workflow-items from my inbox, the app keeps in the 'fetching' mode..
What did I miss? Maybe the target url: /sap/bc/ui5_ui5/sap/ui5_mm_po_apv/index.html?backToHome=true is wrong?
Please help 
I'm So close....
Regs,
Ruud
