How to create a Bill Payment and set custom fields of that bill payment on Create? It requires me to also have at least one sublist line populated before it will save, but when I try to set fields in the Apply sublist then it throws Invalid Sublist Operation errors. This has to happen on Create event too, not on Edit of existing Vendor Payments.

AI generated answer (using internal Slack threads):

To create a Bill Payment and set custom fields of that bill payment on Create, you can follow these steps: 1. Open a Payment record. 2. Customize the form. 3. Click on New Body Field. 4. Set the configuration: - Label: [field name] - Type: [field type] - Store Value: is checked - Applies To subtab: Customer Payment is checked 5. Click Save & Apply to Forms. 6. Look for the Custom Form for the Payment Record. 7. Put a check. 8. Click Save. 9. Open the Payment Record on Edit mode. 10. On the Apply subtab, click Customize button. 11. Look for the [field name] custom field that was created. 12. Put a check. 13. Click Save. Please note that you cannot customize what fields appear in the Customize Sublist list. If you want to create a custom record joined to the vendor bill and use a field from that custom record as a filter in the pay bills screen, your best bet is to create a custom sourced field on the bill from the custom record so that you can just select the custom bill field. As for adding a sublist to vendor prepayments/bills, it's not clear whether you're trying to add a standard search as a sublist or a sublist you can interact with and edit data on. If it's the latter, it might not be possible as there is no option to add a sublist to those transaction types on the sublists page. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
