• What is the cause and solution for SAP error message DBPROC_PROXY022 - Parameter name & is not unique within the procedure ?

  The SAP error message DBPROC_PROXY022 indicates that there is a problem with the parameters defined in a stored procedure. Specifically, the error message states that a parameter name is not unique within the procedure. This typically occurs when two or more parameters in the same stored procedure have the same name, which leads to ambiguity when the procedure is called.
  Cause:
  
  Duplicate Parameter Names: The most common cause of this error is that the stored procedure has been defined with two or more parameters that share the same name.
  Incorrect Procedure Definition: If the procedure was modified and parameters were added or renamed without ensuring uniqueness, this error can occur.
  Database Schema Issues: Sometimes, issues in the database schema or the way the procedure is called can lead to this error.
  
  Solution:
  
  
  Review the Procedure Definition: Check the definition of the stored procedure in the database. Ensure that all parameter names are unique. If you find duplicate names, rename them to ensure uniqueness.
  Example:
  CREATE PROCEDURE MyProcedure
  @Param1 INT,
  @Param2 INT,  -- Ensure this is unique
  @Param1Duplicate INT  -- This will cause the error
  AS
  BEGIN
      -- Procedure logic
  END
  Change it to:
  CREATE PROCEDURE MyProcedure
  @Param1 INT,
  @Param2 INT,
  @Param3 INT  -- Unique name
  AS
  BEGIN
      -- Procedure logic
  END
  
  
  Check Procedure Calls: If the procedure is being called from other parts of the application, ensure that the calls are using the correct parameter names and that there are no conflicts.
  
  
  Recompile the Procedure: After making changes to the parameter names, recompile the stored procedure to ensure that the changes take effect.
  
  
  Test the Procedure: After making the necessary changes, test the procedure to ensure that it executes without errors.
  
  
  Related Information:
  
  Database Documentation: Refer to the database documentation for guidelines on naming conventions and best practices for stored procedures.
  SAP Notes: Check SAP Notes for any specific guidance or patches related to this error message.
  Debugging Tools: Use debugging tools or SQL management tools to analyze the stored procedure and its parameters.
  
  By ensuring that all parameter names are unique within the stored procedure, you should be able to resolve the DBPROC_PROXY022 error.
