Can you update sales orders and opportunities in NetSuite that are in a closed period?

AI generated answer (using internal Slack threads):

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** Based on the conversations, it appears that updating sales orders and opportunities in NetSuite that are in a closed period is not typically allowed. This is because closed periods are often locked to prevent changes that could impact financial reporting and auditing. In one conversation, a user wanted to update a custom field on a CashSale record in a closed period. The response was that the only option to make such a change would be to reopen the period, which is generally not recommended due to the potential impact on financial data. Another suggestion was to create Journal Entries to offset the amounts to the correct departments, but this would not directly update the CashSale record. In another conversation, a user was importing Opportunities, including closed ones, from another system into NetSuite. They wanted to set the actual close date, but found that this was not possible through CSV import or a workflow field update. The responses suggested that the actual close date aligns with the invoices/sales orders being loaded, and if these are not being loaded into NetSuite, it may not be possible to set the actual close date. In conclusion, while there may be workarounds, directly updating sales orders and opportunities in NetSuite that are in a closed period is generally not possible due to the potential impact on financial data.
