Unable to create transactions in multiple subadiaries getting nexus error

AI generated answer (using internal Slack threads):

The error

Transaction Nexus not valid for Transaction Subsidiary

typically refers to a situation where the Nexus associated with the transaction does not match the Nexus associated with the subsidiary. In NetSuite, a Nexus is a relationship or connection between two entities, such as a customer and a subsidiary. If you are trying to create a transaction for a customer who is part of a different subsidiary than your account, you need to ensure that the Nexus of the customer is added in the Nexuses subtab of the Subsidiary record. This is necessary because NetSuite uses the Nexus to determine tax obligations. In the case of the Return Authorization record, the error might be occurring because the shortcut you created is automatically associating the transaction with a Nexus that does not match the subsidiary. To resolve this, you should not create the shortcut while on an order with a customer. Instead, create the shortcut from a neutral location that does not automatically associate a Nexus. Regarding the creation of multiple parent subsidiaries, once a subsidiary hierarchy is created in NetSuite, it cannot be changed. The same rule applies to the base currency and country of the subsidiary.
