• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT087 - You have defined &1 parameters. For IF two or three parameters supported. ?

  The SAP error message /IWBEP/CM_MGW_RT087 indicates that there is an issue with the number of parameters defined in your OData service. Specifically, the message states that you have defined a certain number of parameters (indicated by &1), but the service only supports two or three parameters.
  Cause:
  This error typically occurs when:
  
  You have defined more parameters in your OData service than the maximum allowed (which is usually two or three).
  The service implementation is not aligned with the expected number of parameters for the operation being performed (e.g., a function import or an action).
  There may be a mismatch between the service definition and the actual implementation in the backend.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the OData Service Definition:
  
  Check the service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Look for the function imports or actions that are causing the issue and verify the number of parameters defined.
  
  
  
  Limit the Number of Parameters:
  
  If you have defined more than three parameters, consider refactoring your service to reduce the number of parameters. You can combine parameters into a single complex type if applicable.
  
  
  
  Adjust the Implementation:
  
  Ensure that the backend implementation (e.g., ABAP code) matches the service definition. If you have modified the service definition, make sure to adjust the corresponding ABAP code accordingly.
  
  
  
  Regenerate the Service:
  
  After making changes, regenerate the service and activate it. This can be done in the Service Builder by selecting the service and choosing the "Generate" option.
  
  
  
  Test the Service:
  
  After making the necessary adjustments, test the OData service again to ensure that the error is resolved.
