Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Tax Code Usage: The tax code you are trying to modify is currently in use in an external exchange rate table. This means that the system has dependencies on this tax code, and changing it could lead to inconsistencies in tax calculations.

  Solution:
  
  
  Check Usage: First, identify where the tax code is being used. You can do this by checking the external exchange rate tables and any related configurations. Use transaction codes like OB40 (for maintaining exchange rates) or OBY6 (for tax codes) to review the settings.

  Ensuring that no transactions or configurations are currently using the tax code.
  
  
  
  Change Tax Status: Once you have confirmed that the tax code is no longer in use, you can proceed to change the tax status in the relevant configuration settings.
