Can the Workflow Action "Set Field Value" set the value on Transaction Line Fields?

AI generated answer (using internal Slack threads):

Yes, the Workflow Action "Set Field Value" can set the value on Transaction Line Fields. However, this is only possible if you add a Sublist Action Group. Inside the Sublist Action Group, you can add a new Action of Set Field Value. This only works for the Items sublist. However, it's important to note that this workflow only works for the sublist item and not for the expense. If you want to copy a line level field to the header level, it would require a script or action script workflow. The challenge with this is if you have several lines of information, it's not clear which one would be copied to the header - the first or the last. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
