can I modify the setup of the native "otherrefnum" field?

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that the native "otherrefnum" field in NetSuite is not required by default and can be modified. It is used as a reference to the customer’s Purchase Order (PO) number on Sales Orders (SOs). However, it's important to note that any changes to this field should be handled programmatically to maintain data integrity and satisfy audit requirements. This can be achieved through a workflow or script that writes back to the underlying record. In terms of setting the "otherrefnum" field on a record, it has been confirmed that scripts can be used to set this field on some records, although it's not explicitly stated if this can be done on a PO. If you need to display the "otherrefnum" field (Customer PO numbers) on a statement and it doesn't work, a workaround could be to create a new field on the body and line that sources the "otherrefnum" field and use that value in the PDF instead. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
