• What is the cause and solution for SAP error message SADL_GW_MDE_TABLE003 - Property & already exists in & ?

  The SAP error message SADL_GW_MDE_TABLE003 typically indicates that there is an issue with the metadata definition in the SAP Gateway when trying to create or update a service. The error message states that a property already exists in the specified entity type, which can occur during the definition of a service or when trying to register a new service.
  Cause:
  
  
  Duplicate Property Definition: The error usually arises when there is an attempt to define a property in the metadata that already exists in the entity type. This can happen if:
  
  The same property is defined multiple times in the service definition.
  There is a mismatch in the naming conventions or case sensitivity.
  The service is being generated from a data model that has conflicting definitions.
  
  
  
  Model Changes: If the underlying data model has been changed (e.g., properties added or renamed) and the service has not been updated accordingly, this can lead to conflicts.
  
  
  Caching Issues: Sometimes, caching issues in the SAP Gateway can lead to stale metadata being used, which may cause conflicts.
  
  
  Solution:
  
  
  Check Metadata Definitions: Review the metadata definitions for the service in question. Ensure that there are no duplicate property definitions. You can do this by:
  
  Navigating to the service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Checking the entity types and their properties for duplicates.
  
  
  
  Update Service: If changes have been made to the underlying data model, ensure that the service is updated:
  
  Regenerate the service by right-clicking on the service in the Service Builder and selecting "Generate".
  Activate the service after making changes.
  
  
  
  Clear Cache: If you suspect caching issues, you can clear the cache:
  
  Use transaction code /IWFND/MAINT_SERVICE to manage services and clear the cache.
  You can also use transaction code /IWFND/CACHE to clear the Gateway cache.
  
  
  
  Check Naming Conventions: Ensure that the naming conventions used for properties are consistent and do not conflict with existing properties.
  
  
  Debugging: If the issue persists, consider debugging the service registration process to identify where the conflict is occurring.
