• What is the cause and solution for SAP error message HRPADARINFOTYPES031 - RFC error: TAX_NUMBER_CHECK module cannot be called through RFC ?

  The SAP error message "HRPADARINFOTYPES031 RFC error: TAX_NUMBER_CHECK module cannot be called through RFC" typically occurs when there is an attempt to call a function module that is not designed to be executed in a Remote Function Call (RFC) context. This specific error is related to the TAX_NUMBER_CHECK function module, which is used for validating tax numbers in the HR module.
  Cause:
  
  RFC Restrictions: The TAX_NUMBER_CHECK function module is not RFC-enabled, meaning it cannot be called from a remote system. This is a common restriction for certain function modules that are designed to be executed only in a local context.
  Configuration Issues: There may be configuration issues in the system that lead to the incorrect invocation of this function module in an RFC context.
  Custom Code: If there is custom code or enhancements that attempt to call this function module remotely, it will trigger this error.
  
  Solution:
  
  Check Function Module: Verify if the TAX_NUMBER_CHECK function module is RFC-enabled. You can do this by checking the attributes of the function module in transaction SE37. If it is not RFC-enabled, you cannot call it remotely.
  Local Execution: If you need to use the functionality of TAX_NUMBER_CHECK, consider executing it in a local context instead of through an RFC call. This may involve restructuring your code to ensure that the function is called within the same system.
  Alternative Approaches: If you need to validate tax numbers in a remote context, look for alternative RFC-enabled function modules or create a wrapper function that can handle the logic locally and then return the results to the calling RFC.
  Custom Development: If necessary, you can create a custom RFC-enabled function module that encapsulates the logic of TAX_NUMBER_CHECK and can be called remotely. Ensure that this custom module handles the data appropriately and adheres to the required business logic.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or updates related to the TAX_NUMBER_CHECK function module. SAP may provide patches or recommendations for similar issues.
  Documentation: Review the SAP documentation for the HR module and the specific function module to understand its intended use and limitations.
  Testing: After making changes, thoroughly test the functionality to ensure that tax number validation works as expected without triggering RFC errors.
  
  By following these steps, you should be able to resolve the error and implement a suitable solution for your requirements.
