• What is the cause and solution for SAP error message SCTS_HDI402 - HDI namespace &1&2&3 already exists in container &4 (non-generated) ?

  The SAP error message SCTS_HDI402 indicates that there is an attempt to create an HDI (HANA Deployment Infrastructure) namespace that already exists in the specified container. This error typically occurs during the deployment of HDI artifacts when the system detects that the namespace you are trying to create is already present.
  Cause:
  The error is caused by one of the following reasons:
  
  Namespace Already Exists: The namespace you are trying to create is already defined in the HDI container.
  Deployment Conflict: There may be a conflict with existing artifacts or namespaces in the container that prevent the creation of the new namespace.
  Incorrect Deployment Configuration: The deployment configuration might be incorrectly set up, leading to attempts to create existing namespaces.
  
  Solution:
  To resolve the SCTS_HDI402 error, you can take the following steps:
  
  
  Check Existing Namespaces:
  
  Use the SAP HANA Database Explorer or the HDI container management tools to check if the namespace already exists in the specified container.
  If it exists, you may need to modify your deployment to use the existing namespace instead of trying to create a new one.
  
  
  
  Modify Deployment Artifacts:
  
  If you are trying to deploy artifacts that reference the namespace, ensure that they are correctly configured to use the existing namespace.
  Update your .hdbsynonym or .hdbtable files to reference the existing namespace.
  
  
  
  Clean Up the Container:
  
  If the existing namespace is not needed, you can consider cleaning up the HDI container by removing the unnecessary artifacts or namespaces.
  Be cautious with this approach, as it may affect other applications or services relying on those artifacts.
  
  
  
  Review Deployment Scripts:
  
  If you are using deployment scripts or tools, review them to ensure they are not attempting to create namespaces that already exist.
  
  
  
  Consult Documentation:
  
  Refer to the SAP HANA documentation for more details on HDI namespaces and deployment best practices.
