What are the options to cancel a planned purchase order and to be rejected from planning workbench

AI generated answer (using internal Slack threads):

To cancel a planned Purchase Order (PO) that is not yet fully approved, you can follow these steps: 1. If there is a workflow in action, cancel the workflow system notes - workflow. This essentially detaches the workflow from the PO. 2. Edit and close all the lines on the PO. 3. If desired, you can even delete the PO since it is a non-posting transaction. As for handling rejected POs, you have a few options: 1. Leave them in a rejected state if you don't plan to edit and use them again. 2. Use the lock record action in the workflow to remove the edit option from these POs. This can be useful if you want to prevent users from editing the rejected PO and making changes to get it approved. Please note that keeping POs in a rejected state will still make them visible in the user view. If this is not desirable, you may need to consider other options for handling rejected POs. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
