Anyone using MRP? Is there a difference between MRP and MPS on item records? I can't tell what the difference and there is not much info out there.

The only difference is the MRP / MPS tags on the Workbench. There is no difference in functionality

Thank you!

i would suggest you stick with one over the other so you at least have some consistency if it doesn't change in the future - but i have also not seen these function differently.
