We are having few subsidiaries, and we are using multi currency. i noticed that for few subsidiary i can change the primary currency but for others is blocked, why is that and what i need to change in the settings?

AI generated answer (using internal Slack threads):

In NetSuite, the ability to change the primary currency of a subsidiary is dependent on whether there have been any transactions recorded against that subsidiary. If there have been transactions, the primary currency field will be locked and cannot be changed. This is because changing the primary currency after transactions have been recorded could lead to inconsistencies and inaccuracies in financial reporting. If you need to change the primary currency for a subsidiary that has already had transactions recorded against it, you would need to create a new subsidiary with the desired primary currency and migrate the necessary data over. However, this can be a complex process and should be done with caution to avoid any data loss or inconsistencies. For subsidiaries that have not had any transactions recorded against them, you can change the primary currency by navigating to Setup > Company > Subsidiaries. Select the subsidiary you want to change, and then in the Currency field, select the new primary currency. Click Save to apply the changes. Remember, the primary currency of a subsidiary should typically be the currency of the country where the subsidiary operates. This is because the primary currency is used for financial reporting and tax purposes. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******

In NetSuite, the subsidiary uses a Base Currency rather than a Primary Currency. The field is usually editable only while the subsidiary is new and has no saved records involving currency. Once transactions, accounts, entities, exchange rates, or other currency-linked records exist, NetSuite disables the field to protect the subsidiary’s GL history. So the subsidiaries you can still change likely haven’t been used yet, while the blocked subsidiaries already have related records. There isn’t an accounting preference that unlocks this.
