On Setup > Accounting > Accounting Preferences > Approval Routing, the Vendor Payments checkbox is ticked and greyed out. (Let's refer to these settings "Advanced Approval Routing" because there are standard permissions for approval routing on roles, too.) However, working "Advanced Approval Routing" means I need to configure a SuiteFlow to set the Next Approver field and select an approver for those bill payments. The problem is that Next Approver allows for only a single employee to be selected. Questions: • What would make the checkbox for vendor payments get checked and greyed out? (That must be some core feature, right?) • How to ungrey and subsequently then deactivate Approval Routing for Vendor Bill Payments and go by permissions "Vendor Payment Approval" allowing multiple users to approve the vendor bill payments?

there are already some vendor payment is in que for approval. You need to clear them - then you should be able to uncheck the routing check box.
