PO25 and inventory item

There are a number of things that could cause a req/PO to disregard the contract price.

Was the agreement not released or on hold for some reason when the order was created? Might be difficult to determine. The audit trail on PO25.1/PO25.6 doesn't track when an agreement is released but it will tell you if it was put on hold or when changes were mad that could have put it in an unreleased state.
Was the agreement line on hold?
Does the vendor on the agreement match the vendor selected on the req/PO line?
Is there a purchase from location on the agreement and does that match the req/PO line? If none on the agreement then any purchase from or none on the line should pull the contract cost.
Is there another active agreement for this item with the $7.27 cost? All else being equal, Lawson will choose the lower cost.
How is your cost defaulting order set in PO01.4?
Lastly the participants, but you said those look ok.

Thanks for your reply.
I verified all your suggestions and all looked correct.
What I did notice on PO25.1 was under UOM's MUST MATCH, flag was YES.
On the PO25 line item, the price is $83.10 per CASE. (I incorrectly stated $8.77/BX above).
The PO was created by the BX. (10BX to a Case).
Looks like I need to change UOM MUST MATCH flag to No.

Well, when I tried to change the flag to YES, I got the following error message "UOMs Must Match flag must be Y for items with multiple UOM".
So I changed the PO25 line cost to $8.31/BX.
IC11 has BX as default Buy UOM (1) with Case as Valid UOM (2).
Hoping that corrects it going forward.

I think you found it.

"UOMs Must Match flag must be Y for items with multiple UOM" indicates you have a line(or lines) on there twice with two different UOMs. But yes, if you only buy by BX - that should do it.
