  Cause:

The absence of these values can occur due to several reasons, such as:
  
  Missing Configuration: The tax configuration in the system may not be set up correctly, leading to missing tax base or unit information.
  Data Entry Errors: During the creation of a transaction or document, the required fields may not have been filled out correctly.
  Integration Issues: If the transaction involves data from other systems or modules, there may be issues with data transfer or mapping.
  Business Logic: The business logic implemented in the system may not be correctly handling the calculation of tax bases or units.

  Check the transaction or document that triggered the error. Ensure that all required fields, especially the tax base and tax unit, are filled out correctly.
  If applicable, verify that the relevant master data (e.g., customer or vendor records) is complete and accurate.
  
  
  
  Review Integration Points:
  
  If the transaction involves data from other systems, check the integration points to ensure that data is being transferred correctly.
  Look for any mapping issues that may prevent the tax base or unit from being populated.
  
  
  
  Debugging:
  
  If you have access to debugging tools, you can trace the execution of the program or function module that is generating the error to identify where the values are not being set.
