  The SAP error message CRM_WSC403 indicates that there is an issue with the creation of a source tree in the context of a Web Service Consumer (WSC) in SAP CRM. Specifically, the error states that the method you are trying to use does not have an output parameter defined, which is necessary for the source tree to be created.
  Cause:
  
  Missing Output Parameter: The method you are trying to use in your Web Service does not have any output parameters defined. In SAP, methods that are intended to return data must have output parameters.
  Incorrect Method Definition: The method may not be correctly defined in the service interface or the service implementation.
  Service Interface Issues: There may be issues with the service interface that prevent the proper generation of the source tree.
  
  Solution:
  
  
  Check Method Definition:
  
  Go to the service interface where the method is defined.
  Ensure that the method has at least one output parameter defined. If it does not, you will need to add an appropriate output parameter that matches the expected return type.
  
  
  
  Modify the Service Interface:
  
  If you have access to modify the service interface, add the necessary output parameters to the method.
  Ensure that the output parameters are correctly mapped to the expected data types.
  
  
  
  Regenerate the Source Tree:
  
  After making changes to the method definition, regenerate the source tree in the Web Service Consumer.
  This can usually be done through the transaction code CRMD_ORDER or the relevant transaction for your CRM system.
  
  
  
  Test the Web Service:
  
  After making the necessary changes, test the web service to ensure that it is functioning correctly and that the output parameters are being returned as expected.
