Is it possible to set the 'createpo' field on a sales order item sublist via script?

AI generated answer (using internal Slack threads):

Based on the conversations provided, it seems that the 'createpo' field on a sales order item sublist cannot be directly set via a script. However, it is possible to manipulate related fields and records through scripts, such as triggering a script to update a body level field on a Purchase Order (PO) when a line field on the item receipt has been updated. This would involve creating a UserEvent script using the AfterSubmit method, comparing old and new values on the Item Receipt record using the scriptContext.newRecord and scriptContext.oldRecord passed into the afterSubmit method, and then performing a record.update on the PO if a change is detected. In addition, it is possible to create a custom sublist in a Purchase Order where the user can input information during PO creation, similar to how user inputs info in Expenses/Item sublist. This can be achieved by creating custom child record sublists. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
