• What is the cause and solution for SAP error message CNV_IUUC_DB_CONN138 - View &1 cannot be created; unsupported session context variable ?

  The SAP error message CNV_IUUC_DB_CONN138 indicates that there is an issue with creating a view due to an unsupported session context variable. This error typically arises in the context of data migration or data transformation processes, particularly when using the SAP Landscape Transformation (SLT) or SAP Data Services.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Unsupported Session Context: The session context variable that is being referenced in the SQL statement or view creation is not supported in the current context. This can happen if the variable is not properly defined or if it is being used in a way that is not allowed.
  Database Compatibility: The database system you are using may not support certain features or constructs that are being used in the view definition.
  Configuration Issues: There may be configuration issues in the SLT or data migration setup that prevent the view from being created.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Session Context Variables: Review the session context variables being used in the view definition. Ensure that they are correctly defined and supported in the context where the view is being created.
  
  
  Review SQL Syntax: Check the SQL syntax used in the view creation. Make sure that it adheres to the standards and limitations of the database you are using.
  
  
  Database Compatibility: Ensure that the database you are using is compatible with the features being utilized in the view. If necessary, consult the documentation for your specific database version.
  
  
  Configuration Review: Review the configuration settings in your SLT or data migration setup. Ensure that all necessary parameters are correctly set and that there are no misconfigurations.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes or Knowledge Base Articles that may address this specific error. There may be patches or updates available that resolve the issue.
  
  
  Testing: If possible, try to create a simplified version of the view without the unsupported session context variable to see if it works. This can help isolate the issue.
  
  
  Contact SAP Support: If the issue persists after trying the above steps, consider reaching out to SAP Support for further assistance. Provide them with detailed information about the error, including the context in which it occurs and any relevant logs.
