On Setup > Accounting > Accounting Preferences > Approval Routing, the Vendor Payments checkbox is ticked and greyed out.

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that the Vendor Payments checkbox under Setup > Accounting > Accounting Preferences > Approval Routing is used to enable or disable the approval routing for vendor payments. If it's ticked and greyed out, it means that the approval routing for vendor payments is enabled and cannot be changed. When this option is enabled, you can create an approval workflow for vendor payments. However, it's a complex topic and you may need to refer to SuiteAnswers for detailed instructions. Article #19243 and #83923 are suggested as good starting points. If you're using the Electronic Bank Payments SuiteApp, you may encounter an issue if the approval routing is enabled for vendor payments. This is because the SuiteApp is not compatible with the Vendor Payments preference. In this case, you can go to Payments | Setup | Electronic Payments Preferences and tick the EFT Payment Batch Approval Routing box instead. Please note that you can't have both vendor payment approvals in the system and EFT in the same account - you have to choose one or the other. If you have a custom workflow for Vendor Bills and the approval routing is turned off, you may not see the pending approval bills in the Approve Bills page. In this case, you can create a custom view saved search to see the pending approval bills. If you're using a custom workflow with approval routing enabled, make sure you're setting up the next approver. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
