how to change the currency in a po if it's not received

AI generated answer (using internal Slack threads):

To change the currency in a Purchase Order (PO) that has not been received yet, you would need to delete the existing PO and create a new one with the desired currency. This is because once a transaction is created in NetSuite, certain fields such as currency and subsidiary cannot be changed in order to maintain the integrity of the General Ledger (GL). If you are creating a dropship PO from a Sales Order (SO), the currency of the PO is determined by the primary currency of the vendor record. If you need the PO currency to be different, you can enable the vendor as a multi-subsidiary vendor and set a different currency for each subsidiary. However, this workaround may not be ideal if the PO currency needs to be one of the secondary currencies. As for paying a PO in a different currency, it is possible to pay POs/Bills with a bank account whose currency matches the PO or one that matches the functional currency of the subsidiary the PO is on. For example, if you create a PO in Euro, you can pay it in dollars if the PO is on a USD subsidiary. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
