Hi, I have created a custom vendor field at line level on Expenses of a vendor bill record, and I want to source the header vendor value into this custom field. I know we can pull it from the items sublist, and that works for the Item tab, but it doesn’t work for Expenses. Can you please let me know if there is a way to do it? Your immediate response is highly appreciated.

You cannot manipulate the expenses Sublist using a workflow. It would need to be a script

Thanks, Maven. I knew it could be done using a script, but keep this as a last option. If that is the only way to get it. Can you please share the pointers?

Only item sublist can be used in workflow. In your it's not possible through workflow you must need to use a suite script
