i want formula get the cumulative opening balance in the saves search

AI generated answer (using internal Slack threads):

To get a cumulative opening balance in a saved search, you can create a formula field in your saved search. However, NetSuite does not natively support running totals or cumulative sums in saved searches. A workaround for this is to use a SQL trick involving concatenating a string of numbers and then using the LENGTH function to get a running total. This method was described in a blog post by Marty Zigman / Prolecto. Here is the link to the blog post: https://blog.prolecto.com/2015/05/26/solving-the-netsuite-cumulative-saved-search-tally-challenge/ Please note that this method may not work in all cases and may require adjustments based on your specific needs. For example, you may need to accommodate for different locations and transaction types. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
