Source bill reference on a payment file format. is it ${refnum} or ${tranid} or something else. Do I need to reference the bill record before sourcing this field?

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that the correct reference for the bill on a payment file format would be

${apply.refnum}

. This is the field that references the invoice transaction number on an email template that is sent from a payment record. However, it's important to note that customer payments can have multiple invoices on them, and the invoice related information is found on the apply sublist of the customer payment. If

${apply.refnum}

is not working, it might be due to a configuration issue. The "Reference number" should be on the "Bill Payment" form. If it's not, you might need to look into your configuration settings. Remember, sublists are represented as sequences, so you need to use different syntax to access them. Also, the representation used for your template is the same as when you edit the customer payment, the apply sublist shows multiple invoices available to be applied to, not just the ones you selected. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
