• What is the cause and solution for SAP error message DBPROC_PROXY057 - INOUT parameters are not supported (&) ?

  The SAP error message DBPROC_PROXY057 indicates that there is an issue with the use of INOUT parameters in a database procedure call. This error typically arises when a database procedure is invoked with parameters that are not supported in the context of the operation being performed.
  Cause:
  
  INOUT Parameters: The error specifically points to the use of INOUT parameters, which are parameters that can both receive input values and return output values. Not all database systems or configurations support INOUT parameters, especially in certain contexts or with specific types of procedures.
  Database Compatibility: The database you are using may not support INOUT parameters in the way that the SAP application is trying to use them. This can happen if the database is not configured correctly or if the procedure itself is not defined to handle INOUT parameters.
  Procedure Definition: The procedure being called may not be defined correctly to accept INOUT parameters, or there may be a mismatch between the expected parameter types and the actual parameters being passed.
  
  Solution:
  
  Check Procedure Definition: Review the definition of the database procedure to ensure that it is correctly defined to accept INOUT parameters. Make sure that the parameter types match what is being passed from the SAP application.
  Modify Parameter Usage: If the database does not support INOUT parameters, consider modifying the procedure to use either IN or OUT parameters only. This may involve changing the logic of how data is passed to and from the procedure.
  Database Compatibility: Ensure that the database version and configuration are compatible with the SAP application. If necessary, consult the database documentation to confirm support for INOUT parameters.
  SAP Notes and Documentation: Check SAP Notes and documentation for any known issues or patches related to this error. SAP may have specific recommendations or updates that address this issue.
  Testing: After making changes, thoroughly test the procedure call to ensure that it works as expected without generating the error.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidance on database procedures and parameter handling.
  Database Documentation: Consult the documentation for the specific database you are using (e.g., HANA, Oracle, SQL Server) to understand how it handles INOUT parameters.
