Smart SAP Assistant

• What is the cause and solution for SAP error message /IWNGW/CM_BEP_RT005 - Methods '&1' not implemented in provider id '&2' ?

  The SAP error message /IWNGW/CM_BEP_RT005 Methods '&1' not implemented in provider id '&2' typically occurs in the context of SAP Gateway services, particularly when a method that is expected to be implemented in a service provider is not found. This can happen in OData services when the backend implementation does not support the requested operation.
  Cause:
  
  Missing Implementation: The specified method (e.g., GET, POST, PUT, DELETE) is not implemented in the backend service provider.
  Incorrect Service Configuration: The service might not be properly configured to expose the required methods.
  Service Activation: The OData service might not be activated or properly registered in the SAP Gateway.
  Provider ID Issues: The provider ID specified in the error message may not correspond to a valid service or may be incorrectly configured.
  
  Solution:
  
  
  Check Implementation:
  
  Go to the transaction code SEGW (Gateway Service Builder) and check the service definition.
  Ensure that the method indicated in the error message is implemented in the corresponding entity set.
  
  
  
  Implement Missing Methods:
  
  If the method is not implemented, you need to implement it in the service. This can be done by:
  
  Right-clicking on the entity set in the service builder.
  Selecting "Implement" and then choosing the appropriate method (e.g., GET_ENTITY, GET_ENTITYSET, etc.).
  Writing the necessary ABAP code to handle the request.
  
  
  
  
  
  Check Service Registration:
  
  Use transaction code IWFND/MAINT_SERVICE to check if the service is registered and active.
  If not, register the service and ensure it is activated.
  
  
  
  Check Service Metadata:
  
  Use the URL http://<your_sap_system>:<port>/sap/opu/odata/sap/<service_name>/$metadata to check the service metadata.
  Ensure that the methods you expect to be available are listed in the metadata.
  
  
  
  Debugging:
  
  If the issue persists, you can debug the service call to see where it fails. Use transaction SE80 or SE37 to analyze the function modules or methods involved.
  
  
  
  Check Authorization:
  
  Ensure that the user has the necessary authorizations to access the service and the methods.
