• What is the cause and solution for SAP error message EZ754 - Import parameter &1 already exists ?

  The SAP error message EZ754, which states "Import parameter &1 already exists," typically occurs during the execution of a function module or method where an import parameter is being defined or passed, but a parameter with the same name has already been defined in the same context. This can happen in various scenarios, such as when creating or modifying function modules, methods, or when using certain ABAP constructs.
  Cause:
  
  Duplicate Parameter Definition: The most common cause is that the import parameter is defined more than once in the function module or method signature.
  Inconsistent Naming: If you are trying to import a parameter with a name that is already used in the same scope, it will lead to this error.
  Copy-Paste Errors: Sometimes, copying and pasting code can inadvertently lead to duplicate parameter definitions.
  
  Solution:
  
  Check Parameter Definitions: Review the function module or method definition to ensure that each import parameter has a unique name. Remove or rename any duplicate parameters.
  Refactor Code: If you find that the same parameter is needed in different contexts, consider refactoring your code to avoid duplication. You might need to change the parameter name or consolidate the logic.
  Use Unique Names: When defining parameters, use descriptive and unique names to avoid conflicts. This is a good practice in general programming to enhance code readability and maintainability.
  Check for Includes: If your function module or method includes other includes or uses inheritance, ensure that there are no conflicting parameter names in those included definitions.
  
  Related Information:
  
  Function Module/Method Definition: When defining a function module or method, you can specify import, export, and changing parameters. Ensure that the names are unique across all parameter types.
  ABAP Development Guidelines: Following best practices in ABAP development can help prevent such issues. This includes naming conventions and code organization.
  Debugging: If you encounter this error during runtime, use the debugger to trace back to the point where the parameters are being passed to identify the source of the duplication.
  
  By addressing the above points, you should be able to resolve the EZ754 error and ensure that your function modules or methods work as intended.
