Blanket Order set up

We are on E1 9.2.5.3 - trying to set up a demo of blanket order processing. I am following document

E1: 43: Blanket Orders in Procurement (P4310, P43060) (Doc ID 2284834.2)

to complete set up. When I enter a PO via P4310 in my version set to the instructions in the document I do not get the green checkmark nor the Blanket Exists indicator in the grid. I entered the Supplier and item same as OB. When I move to next line I can see that the price updates to the OB rate as expected.

Am I perhaps following an old document? Any help is greatly appreciated! The attachment includes screenshots of my setup.
