When we try to create workflow rule sets for "FIN AP INVOICE APPROVAL" in BPM, it is directing us to the "Manage Workflow Rules in Spreadsheet" task to configure the rules for the Payables Invoice Approval workflow. We have planned to handle all ERP workflows in BPM. Is there a way to enable the BPM approach in the instance, or is the "Manage Workflow Rules in Spreadsheet" task the only option available for creating workflows for AP? Please let us know.
