• What is the cause and solution for SAP error message CONV351 - Function module is not contained in whitelist ?

  The SAP error message CONV351 indicates that a function module is not included in the whitelist for the system. This typically occurs in the context of security measures implemented in SAP systems, particularly when using the SAP NetWeaver Application Server.
  Cause:
  The error arises when a function module that is being called is not part of the approved list (whitelist) of function modules that can be executed. This is often a security feature to prevent unauthorized or potentially harmful function calls. The whitelist is a configuration that restricts which function modules can be executed in certain contexts, such as remote function calls (RFC) or web services.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Identify the Function Module: Determine which function module is causing the error. This information is usually provided in the error message or can be found in the logs.
  
  
  Check Whitelist Configuration:
  
  Go to transaction SE37 (Function Builder) and enter the name of the function module to check its properties.
  Verify if the function module is indeed not included in the whitelist.
  
  
  
  Add to Whitelist:
  
  If you have the necessary authorizations, you can add the function module to the whitelist. This is typically done in the transaction SICF (Maintain Service) or through specific configuration settings in the system.
  Navigate to the relevant service or configuration area and add the function module to the whitelist.
  
  
  
  Consult Security Policies: Before adding a function module to the whitelist, ensure that it complies with your organization's security policies. Adding a function module to the whitelist can expose the system to risks if the function is not secure.
  
  
  Testing: After making changes, test the functionality to ensure that the error is resolved and that the system behaves as expected.
  
  
  Documentation: Document any changes made to the whitelist for future reference and compliance purposes.

  Security Best Practices: Familiarize yourself with SAP security best practices to ensure that you are not inadvertently exposing your system to vulnerabilities by modifying the whitelist.
  System Logs: Review system logs (transaction SM21) for any additional context or related errors that may help in diagnosing the issue.
  
  If you are not authorized to make these changes or if you are unsure about the implications, it is advisable to consult with your SAP Basis or security team for assistance.
