Hi there,
Good day!
There can be multiple used cases when it comes to using power automate with SAP By Design especially procurement.
1- Approval process: As per my limited knowledge and experience about procurement process, one thing is for sure the multiple level of approval processes. Power automate gives you approval flows that can be initiated via email and it can optimize the process. (Learning Link)
2- Process Advisor: As usually procurement process have multiple stages so we can leverage out process advisor option that will help in explaining out the individual stages of the process stages that may require redesigning and optimization. (Learning Link)
Happy Learning & remember "This low code no code is the way ;)"
