How to change customer on project

AI generated answer (using internal Slack threads):

In NetSuite, once a transaction is linked to a project record, the option to change the customer is removed. This is standard functionality and cannot be changed as the customer gets associated with a lot of transactions when you hit the project record on a transaction. The only workaround is to create a new project with the correct customer and update the transaction records via CSV import, mass update, scripting, etc. If you have advanced projects enabled, you should be able to select a subsidiary without selecting a customer in the project. If you are unable to do so, it could be due to a form issue, a workflow, or a script disabling the subsidiary. For basic projects, you have to create the project from the customer record. If you are unable to do so, it could be due to someone disabling the Projects feature in the Setup. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
