How an accounting rule can be defined in SLA in costing that will derive a certain account based on PO line/ PO total amount for a specific purchase category. I tried defining a segment rule for expense class in Deliver to Inventory event type as below but didn't work since this rule didn't appear in JERS account segment for Expense as "Line Amount" is not a source for "Deliver to Inventory", checked in Manage Subledger Application Transaction Objects - PO Delivery into Inventory.
