• What is the cause and solution for SAP error message M&171 - Subroutines cannot be created in production systems (SAP Note 1651031) ?

  The SAP error message M&171 indicates that subroutines cannot be created in production systems. This is a common restriction in SAP environments to maintain system integrity and stability, especially in production environments where changes should be controlled and minimized.
  Cause:
  The primary cause of this error is that the system is configured to prevent the creation of subroutines in production systems. This is a standard practice in SAP to ensure that only tested and approved changes are made in production environments. Subroutines are typically created during development or testing phases, and allowing their creation in production could lead to untested code being executed, which can cause system instability or errors.
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check System Configuration: Ensure that you are working in the correct environment. If you are in a production system, you should not be trying to create subroutines directly.
  
  
  Use Development or Quality Assurance Systems: If you need to create or modify subroutines, do so in a development or quality assurance (QA) system. After testing, you can transport the changes to the production system using the SAP transport management system.
  
  
  Transport Requests: If you have created subroutines in a development environment, create a transport request to move these changes to the production system. Ensure that all changes are thoroughly tested before transporting.
  
  
  Review SAP Notes: Check SAP Note 1651031 and any related notes for additional guidance or updates regarding this error. SAP Notes often provide specific instructions or workarounds for known issues.
  
  
  Consult with Basis Team: If you believe that there is a need to change this configuration (which is generally not recommended), consult with your SAP Basis team or system administrator. They can provide insights into the implications of such changes.
  
  
  Related Information:
  
  SAP Notes: Always refer to the latest SAP Notes for updates on specific error messages and their resolutions. SAP Note 1651031 may have additional context or updates.
  Transport Management: Familiarize yourself with the SAP transport management system, as it is crucial for moving changes from development to production.
  Development Best Practices: Follow best practices for development in SAP, including proper testing and documentation of changes before moving them to production.
  
  By adhering to these guidelines, you can effectively manage the creation of subroutines and avoid encountering the M&171 error in production systems.
