Id form is an invalide custom form Some item import successfully but the rest failed

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like you're encountering an issue with the CSV import in NetSuite where the custom form ID is not being recognized, causing some items to fail during the import. This could be due to a few reasons: 1. The custom form ID you're using is not valid or active. Please double-check the ID and its status. 2. The custom form is not selected in the advanced import options. Before running the import, you should select the custom form from the drop-down menu in the advanced options. 3. The custom form is not set as the preferred form. If the standard form is set as the preferred form, it might cause issues with the import. If you're trying to keep the current custom form on the item during the CSV import, one solution could be to separate your imports by form. However, this might not be feasible if you can't see the current form on the item. Another solution could be to use the standard form during the import and see if it changes the form stored with the record. However, this might result in some unexpected behavior, such as changing the form to the preferred form set on the Custom Entry Forms 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. ******
