• What is the cause and solution for SAP error message CNV_00001161 - Method &1 has more than one exporting parameter ?

  The SAP error message CNV_00001161 indicates that a method in an ABAP class has been defined with more than one exporting parameter, which is not allowed in certain contexts, particularly when using the SAP Conversion Tools or during data migration processes.
  Cause:
  The error occurs because:
  
  In ABAP, methods can have multiple parameters, but when a method is expected to have only one exporting parameter (for example, when being called in a specific context), having more than one leads to this error.
  This can happen if the method signature is incorrectly defined or if the method is being called in a way that expects a single exporting parameter.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Method Definition:
  
  Go to the ABAP class where the method is defined.
  Review the method signature and ensure that it has only one exporting parameter. If it has multiple exporting parameters, consider refactoring the method to either:
  
  Combine the parameters into a single structure or table.
  Change the method to use importing parameters instead of exporting parameters if applicable.
  
  
  
  
  
  Modify Method Call:
  
  If the method is being called from another location, ensure that the call is made correctly according to the method's definition. If the method is expected to have only one exporting parameter, ensure that the call aligns with that expectation.
  
  
  
  Refactor Code:
  
  If the method is part of a larger codebase or framework, consider refactoring the code to ensure that it adheres to the expected method signature.
  
  
  
  Testing:
  
  After making changes, test the method to ensure that it behaves as expected and that the error no longer occurs.
  
  
  
  Related Information:
  
  ABAP Method Signatures: In ABAP, methods can have different types of parameters: importing, exporting, changing, and returning. Understanding how to properly define and use these parameters is crucial for avoiding such errors.
  SAP Documentation: Refer to the official SAP documentation for guidelines on method definitions and best practices in ABAP programming.
  SAP Community: Engaging with the SAP Community forums can provide insights and solutions from other developers who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the CNV_00001161 error and ensure that your method definitions comply with the expected standards.
