invoice group page missing add to group button

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like you're having trouble with the 'Add to Group' button missing on the Invoice Group page. This could be due to a few reasons: 1. The 'For Invoice Grouping' checkbox is not enabled on the Sales Order. This checkbox indicates that the sales orders will get grouped. You can find this checkbox on the sales order page. Here is the documentation for reference: https://netsuite.custhelp.com/app/answers/detail/a_id/94869/related/1 2. There might be scripts or workflows running on the Invoice items sublist that are causing issues. If you have any scripts or workflows running, try turning them off and then turning them back on one by one to test which one is causing the error. 3. If you're using Item Group instead of Kit, make sure you're not trying to edit the end of group line. If you're getting an error message saying 'You cannot edit the end of group line. You must delete the group.', it might be due to a workflow trying to update the end of group line. You can put a condition to only update items in the sublist that are not description items or do not contain “End of Group”. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
