Expense Procurement Using Deliver-To Location Without Inventory Org

We require guidance on supporting expense procurement (PR, PO, and Receiving) using only a Deliver-To Location without relying on an Inventory Organization. Although a default Inventory Org is system-mandated, it is intended only for technical purposes and should not influence accounting, approvals, or transaction processing. We seek clarification on feasible configurations, handling of account derivation without org dependency, and any potential system limitations or impacts on existing setups.
