• What is the cause and solution for SAP error message SDDL_PARSER_MSG143 - Old and new client annotations must not be combined ?

  The SAP error message SDDL_PARSER_MSG143 indicates that there is a conflict between old and new client annotations in your SAP system. This typically occurs when there is an attempt to use both old-style and new-style annotations in the same context, which is not allowed.
  Cause:
  
  Mixing Annotations: The error arises when both old and new client annotations are used together in a single request or configuration. This can happen during the development of OData services or when configuring SAP Gateway services.
  Inconsistent Metadata: If the metadata definitions for the service are not consistent, it can lead to this error. This might occur if there are changes in the service definitions that have not been properly updated or synchronized.
  
  Solution:
  
  
  Review Annotations: Check the annotations used in your OData service or configuration. Ensure that you are using either the old or the new style, but not both. 
  
  Old annotations typically start with @ and are used in the context of the older versions of the OData services.
  New annotations are more structured and follow the latest standards.
  
  
  
  Update Service Definitions: If you are using an older version of the service, consider updating it to use the new annotations. This may involve:
  
  Modifying the service definition in the SAP Gateway.
  Regenerating the service to ensure that it uses the correct annotations.
  
  
  
  Check for Consistency: Ensure that all parts of your service (including the metadata and any related configurations) are consistent and do not mix old and new annotations.
  
  
  Clear Cache: Sometimes, cached versions of the service can cause issues. Clear the cache for the OData service and try again.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the differences between old and new annotations and how to properly implement them.
