why are you unable to set a specific currency for a bank account related to a customer payment

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. ****** In NetSuite, the currency of a bank account is set at the time of creation and cannot be changed. This is because the bank account is tied to the base currency of the subsidiary it is associated with. When making vendor payments, users can only select bank accounts that have the same currency as the vendor or the company's base currency. For example, if a vendor's currency is US Dollars and the user's base currency is also US Dollars, users may only pay from a US Dollar bank account. Other bank currencies are restricted from the list of available bank accounts. This restriction also applies to customer payments. The currency of the customer payment must match the currency of the bank account. In your case, if you are trying to pay a bill in USD from a bank account in GBP, NetSuite will not allow this. Even if the vendor base currency was in GBP, it would not work because the bank account currency must match the vendor or company's base currency. There are workarounds, such as creating a sub-account of the GBP bank account denominated in USD, and paying from that. Then transfer the amount at the relevant exchange rate out of the GBP account. However, these workarounds may involve a lot of transfers and intercompany work. Please note that any deviation from this native process would require heavy scripting.
