If you want to keep the previous tax code, you might need to manually set it back after the customer change. However, this could be a complex process depending on your specific business rules and requirements. One possible solution could be to use a SuiteScript to set the tax code back to its original value after the customer change. This would involve writing a script that triggers on the customer field change, captures the original tax code, and then sets it back after the customer change. Another approach could be to use a tax schedule instead of a tax item in the customer record. In a tax schedule, you can assign different tax codes per nexus. This could potentially allow you to set specific tax codes for specific customer types buying specific item types in specific nexuses. Please note that these are general suggestions and may not work in all scenarios. You should test any changes thoroughly in a sandbox environment before deploying them to your live account.
