• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED112 - NP bind. (ES '&1'): Complex type '&2' not found for property '&3' ?

  The SAP error message /IWBEP/CM_V4_MED112 NP bind. (ES '&1'): Complex type '&2' not found for property '&3' typically occurs in the context of SAP Gateway and OData services. This error indicates that the OData service is trying to bind a property that is expected to be of a complex type, but the specified complex type cannot be found in the metadata.
  Causes:
  
  Missing Complex Type Definition: The complex type that is referenced in the OData service is not defined in the service's metadata.
  Incorrect Metadata: The metadata might not be properly generated or might be outdated, leading to discrepancies between the service definition and the actual implementation.
  Service Registration Issues: The OData service might not be properly registered or activated in the SAP Gateway.
  Model Issues: There could be issues with the data model or the way the entity types and complex types are defined in the service.
  
  Solutions:
  
  
  Check Metadata: Verify that the complex type is defined in the service's metadata. You can do this by accessing the service's metadata URL (e.g., http://<host>:<port>/sap/opu/odata/sap/<service_name>/$metadata) and checking for the presence of the complex type.
  
  
  Regenerate Service: If the complex type is missing, you may need to regenerate the OData service. This can be done using transaction code /IWFND/MAINT_SERVICE to maintain and activate the service.
  
  
  Check Data Model: Review the data model in the service definition (using transaction code SEGW) to ensure that the complex type is correctly defined and associated with the appropriate entity types.
  
  
  Activate Service: Ensure that the OData service is activated in the SAP Gateway. You can do this in the same transaction mentioned above.
  
  
  Clear Cache: Sometimes, clearing the cache can resolve issues related to outdated metadata. You can do this using transaction code /IWFND/CACHE to clear the OData cache.
  
  
  Check for Typos: Ensure that there are no typos in the names of the complex types or properties in your service definition.
  
  
  Debugging: If the issue persists, consider debugging the OData service to trace where the error is occurring and gather more context about the missing complex type.
