Minimum period window size is set to 2 but all future periods are open

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like you're dealing with an issue related to the period window size in NetSuite. The period window size is a setting that determines how many future periods can be open at a time. If you have set the minimum period window size to 2, it means that at least two future periods must be open at all times. However, you mentioned that all future periods are open, which seems unusual. This could be due to a configuration issue or a misunderstanding of how the period window size works. In NetSuite, you can close a period only if all previous periods are closed. This is indicated by a green checkmark in the period close column. If you're getting a message to close a previous period before working on a new one, it could be because a previous period is still open. Also, it's important to note that when you're bringing in open transactions to a subsidiary in a OneWorld environment, you can date them correctly but select the current period as the posting period. However, you need to ensure that the 'Allow Non-G/L Changes' box is checked in the Accounting Preferences. Remember, foreign currency exchange rates are something you need to watch out for. You should mirror the original rate on your open items and post the foreign exchange revaluation reversal in your first active period. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
