P43081 Cannot remove message for approved purchase order in E1 9.0

Hello Distribution Community,

When a user modifies a PO detail line that is at next status 280 or 400, then the line status reverts to 230 as expected. The purchasing manager re-approves the order and the line status moves to 280. Then either the purchasing manager or the buyer uses P43025 to move the order to status 400. So far, so good.

At some later date when the purchasing manager inquires on Approval Program P43081, the order still appears in the queue for orders awaiting approval.

The purchasing manager selects the orders, and P43081 moves to W43081B Purchase Order Approval. The "Status" field shows "Approved".
