Do custom records affect transaction line usage?

AI generated answer (using internal Slack threads):

Based on the provided Slack threads, it appears that custom records can indeed affect transaction line usage in NetSuite. In the first thread, a user reports an issue with custom transaction records returning doubled values intermittently. This issue seems to be related to the "Main Line" criteria in the search. If the "Main Line" criteria is not defined, the search result may return duplicate lines. However, the user reports that even with "Main Line" set to True, the issue persists, suggesting that there may be a problem with NetSuite itself. In the second thread, a user asks if a custom Transaction Line field on an item fulfillment can be sourced from a native transaction line field on the sales order. The response suggests that this is possible by selecting the appropriate transactions in the custom line field's record and ensuring that the field is shown in the selected transaction's form. In the third thread, a user asks how to create a custom transaction record with their line items. The response provides a link to the NetSuite help center, suggesting that creating custom transaction records with line items is possible. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
