• What is the cause and solution for SAP error message S1112 - & parameter & is defined twice ?

  The SAP error message S1112, which states that a parameter is defined twice, typically occurs when there is a conflict in the definition of parameters in a program or function module. This can happen in various scenarios, such as when you are defining parameters in a report, function module, or method, and you inadvertently use the same name for multiple parameters.
  Cause:
  
  Duplicate Parameter Names: The most common cause is that the same parameter name has been defined more than once within the same scope (e.g., in a function module or method).
  Inclusion of Multiple Includes: If you are using includes in your program, and the same parameter is defined in multiple includes, this can lead to the error.
  Inheritance Issues: In object-oriented programming, if a method in a subclass has a parameter with the same name as a parameter in the superclass, it can lead to this error.
  
  Solution:
  
  Check Parameter Definitions: Review the code where the error occurs and ensure that each parameter has a unique name. Rename any duplicate parameters to resolve the conflict.
  Review Includes: If you are using includes, check all included programs or function modules to ensure that the same parameter is not defined in multiple places.
  Check Inheritance: If you are working with classes, ensure that method parameters do not conflict with inherited parameters. Rename them if necessary.
  Use Unique Naming Conventions: Implement a naming convention that helps avoid such conflicts in the future, such as prefixing parameter names with the function/module name.
  
  Related Information:
  
  Debugging: Use the ABAP debugger to step through the code and identify where the duplicate parameter is being defined.
  Documentation: Refer to SAP documentation or the ABAP programming guidelines for best practices on parameter naming and scope management.
  SAP Notes: Check SAP Notes for any specific issues related to your version of SAP that might provide additional context or solutions.
  
  By following these steps, you should be able to resolve the S1112 error and prevent it from occurring in the future.
