• What is the cause and solution for SAP error message SO326 - Only parameters of type PC can be maintained in a non-SAP system ?

  The SAP error message SO326 ("Only parameters of type PC can be maintained in a non-SAP system") typically occurs when there is an attempt to maintain or configure parameters in a non-SAP system (like a third-party email system) that are not compatible with the expected parameter types in SAP.
  Cause:
  The error arises because SAP is trying to access or modify parameters that are not supported in the context of a non-SAP system. Specifically, the parameters in question are expected to be of type "PC" (which stands for "parameter class"), but the system being used does not support this type.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Configuration: Ensure that the configuration settings for the non-SAP system are correct. Verify that the parameters you are trying to maintain are indeed compatible with the non-SAP system.
  
  
  Use Compatible Parameters: If you are trying to maintain parameters that are specific to SAP, you may need to switch to parameters that are compatible with the non-SAP system. Review the documentation for the non-SAP system to identify the correct parameters.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address this issue. SAP frequently releases notes that provide fixes or workarounds for known issues.
  
  
  Consult Documentation: Review the documentation for both SAP and the non-SAP system to understand the limitations and requirements for parameter maintenance.
  
  
  Contact Support: If the issue persists, consider reaching out to SAP support or the support team for the non-SAP system for further assistance.
  
  
  Related Information:
  
  Parameter Types: Familiarize yourself with the different parameter types in SAP and how they interact with external systems.
  Integration Scenarios: If you are integrating SAP with a non-SAP system, ensure that you are following best practices for integration, including the use of middleware if necessary.
  System Compatibility: Always check the compatibility of the systems involved in the integration to avoid such errors.
  
  By following these steps, you should be able to identify the root cause of the SO326 error and implement a suitable solution.
