• What is the cause and solution for SAP error message ECATT_ODATA_ST_TST126 - &1: No containers found in metadata ?

  The SAP error message ECATT_ODATA_ST_TST126 with the description "No containers found in metadata" typically occurs in the context of using eCATT (extended Computer Aided Test Tool) for testing OData services. This error indicates that the eCATT tool is unable to find any containers in the metadata of the OData service you are trying to test.
  Causes:
  
  
  Missing or Incorrect Metadata: The OData service may not have been properly defined, or the metadata might not be accessible. This can happen if the service is not correctly implemented or if there are issues with the service registration.
  
  
  Service Not Active: The OData service might not be active or published, leading to the inability to retrieve the metadata.
  
  
  Authorization Issues: There may be authorization issues preventing access to the OData service or its metadata.
  
  
  Network Issues: If the OData service is hosted on a different server, network issues could prevent access to the metadata.
  
  
  Incorrect URL: The URL used to access the OData service might be incorrect, leading to a failure in retrieving the metadata.
  
  
  Solutions:
  
  
  Check OData Service Activation: Ensure that the OData service is active and properly registered in the SAP Gateway. You can check this in the SAP Gateway Service Builder (transaction code /IWFND/MAINT_SERVICE).
  
  
  Verify Metadata URL: Access the metadata URL directly in a web browser to see if it returns the expected XML or JSON metadata. The URL typically looks like http://<host>:<port>/sap/opu/odata/sap/<service_name>/$metadata.
  
  
  Review Service Implementation: If you are the developer of the OData service, review the implementation to ensure that it correctly defines the entities and their properties.
  
  
  Check Authorizations: Ensure that the user executing the eCATT script has the necessary authorizations to access the OData service and its metadata.
  
  
  Network Configuration: If the service is hosted on a different server, check the network configuration to ensure that there are no firewalls or other issues blocking access.
  
  
  Debugging: If you have access to the backend, you can debug the OData service to see if there are any runtime errors that might be causing the metadata to be unavailable.
